Abstract
Existing drugs that are being used to treat type-2 diabetes mellitus are associated with several side effects; thus, exploring potential drug candidates is still an utter need these days. Hybrids of indenoquinoxaline and hydrazide have never been explored as antidiabetic agents. In this study, a series of new indenoquinoxaline-phenylacrylohydrazide hybrids (1-30) were synthesized, structurally characterized, and evaluated for α-amylase and α-glucosidase inhibitory activities, as well as for their antioxidant properties. All scaffolds exhibited varying degrees of inhibitory activity against both enzymes, with IC50 values ranging from 2.34 to 61.12 μM for α-amylase and 0.42 to 54.72 μM for α-glucosidase. Particularly, compounds 10, 16, 17, 18, 24, and 25 demonstrated the highest efficacy in inhibiting α-amylase, while compounds 6, 7, 8, 10, 12, 14, 13, 16, 17, 18, 24, and 25 were the most effective α-glucosidase inhibitors, compared to standard acarbose. Moreover, most of these compounds displayed substantial antioxidant potential compared to standard butylated hydroxytoluene (BHT). Kinetics studies revealed competitive inhibition modes by compounds. Furthermore, a comprehensive in silico study and toxicity prediction were also conducted, further validating these analogs as potential drug candidates. The structured compounds demonstrated enhanced profiles, underscoring their potential as primary candidates in drug discovery.

Abstract
A series of 3-substituted and 3,5-disubstituted rhodanine-based derivatives were synthesized from 3-aminorhodanine and examined for α-amylase inhibitory, DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities in vitro. These derivatives displayed significant α-amylase inhibitory potential with IC50 values of 11.01-56.04 µM in comparison to standard acarbose (IC50 = 9.08 ± 0.07 µM). Especially, compounds 7 (IC50 = 11.01 ± 0.07 µM) and 8 (IC50 = 12.01 ± 0.07 µM) showed highest α-amylase inhibitory activities among the whole series. In addition to α-amylase inhibitory activity, all compounds also demonstrated significant scavenging activities against DPPH and ABTS radicals, with IC50 values ranging from 12.24 to 57.33 and 13.29-59.09 µM, respectively, as compared to the standard ascorbic acid (IC50 = 15.08 ± 0.03 µM for DPPH; IC50 = 16.09 ± 0.17 µM for ABTS). These findings reveal that the nature and position of the substituents on the phenyl ring(s) are crucial for variation in the activities. The structure-activity relationship (SAR) revealed that the compounds bearing an electron-withdrawing group (EWG) at para substitution possessed the highest activity. In kinetic studies, only the km value was changed, with no observed changes in Vmax, indicating a competitive inhibition. Molecular docking studies revealed important interactions between compounds and the α-amylase active pocket. Further advanced research needs to perform on the identified compounds in order to obtain potential antidiabetic agents.

Abstract
Glycerophosphodiester phosphodiesterase (GDPD) is a highly conserved enzyme in both prokaryotic and eukaryotic organisms. It catalyses the hydrolysis of various glycerophosphodiesters into glycerol-3-phosphate and corresponding alcohols, which serve as building blocks in several biosynthetic pathways. This enzyme is a well-known virulence factor in many pathogenic bacteria, including Staphylococcus aureus, and is thus considered a potential drug target. In this study, competent E. coli BL21(DE3)pLysS expression cells were used to express the GDPD enzyme from vancomycin-resistant Staphylococcus aureus (VRSA), which was then purified using size exclusion and anion exchange chromatography. The hydrolytic activity of GDPD was evaluated on the non-physiological substrate bis(p-nitrophenyl) phosphate (BpNPP), which indicated functional activity of the enzyme. 79 drugs were evaluated for their inhibitory potential against GDPD enzyme by the colorimetric assay. Out of 79 drugs, 13 drugs, including tenofovir (1), adenosine (2), clioquinol (11), bromazepam (12), lamotrigine (13), sulfadiazine (14), azathioprine (15), nicotine (16), sitagliptin PO4 (17), doxofylline (18), clindamycin phosphate (19), gentamycin sulphate (20), and ceftriaxone sodium (21) revealed varying degrees of inhibitory potential with IC50 values in the range of 400 ± 0.007-951 ± 0.016 µM. All drugs were also evaluated for their binding interactions with the target enzyme by saturation transfer difference (STD-NMR) spectroscopy. 10 drugs demonstrated STD interactions and hence, showed binding affinity with the enzyme. Exceptionally, tenofovir (1) was identified to be a better inhibitor with an IC50 value of 400 ± 0.007 µM, as compared to the standard EDTA (ethylenediaminetetraacetic acid) (IC50 = 470 ± 0.008 µM). Moreover, molecular docking studies have identified key interactions of the ligand (tenofovir) with the binding site residues of the enzyme.

Abstract
A rare but lethal central nervous system disease known as granulomatous amoebic encephalitis (GAE) and potentially blinding Acanthamoeba keratitis are diseases caused by free-living Acanthamoeba. Currently, no therapeutic agent can completely eradicate or prevent GAE. Synthetic compounds are a likely source of bioactive compounds for developing new drugs. This study synthesized seventeen 1,4-benzothiazine derivatives (I -XVII) by a base-catalyzed one-pot reaction of 2-amino thiophenol with substituted bromo acetophenones. Different spectroscopic techniques, such as EI-MS, 1H-, and 13C NMR (only for the new compounds), were used for the structural characterization and conformation of compounds. These compounds were assessed for the first time against Acanthamoeba castellanii. All compounds showed anti-amoebic potential in vitro against A. castellanii, reducing its ability to encyst and excyst at 100 μM. Compounds IX, X, and XVI showed the most potent activities among all derivatives and significantly reduced the viability to 5.3 × 104 (p < 0.0003), 2 × 105 (p < 0.006), and 2.4 × 105 (p < 0.002) cells/mL, respectively. The cytotoxicity profile revealed that these molecules showed lower to moderate cytotoxicity, i.e., 36 %, 2 %, and 21 %, respectively, against human keratinocytes in vitro. These results indicate that 1,4-benzothiazines showed potent in vitro activity against trophozoites and cysts of A. castellanii. Hence, these 1,4-benzothiazine derivatives should be considered to develop new potential therapeutic agents against Acanthamoeba infections.

Abstract
Inhibiting α-glucosidase is a reliable method for reducing blood sugar levels in diabetic individuals. Bis(dimethylamino)benzophenone derivatives 1-27 were synthesized from bis(dimethylamino)benzophenone via two-step reaction. Different spectroscopic techniques, including EI-MS and 1H NMR, were employed to characterize all synthetic derivatives. The elemental composition of synthetic compounds was confirmed by elemental analysis and results were found in agreement with the calculated values. The synthetic compounds 1-27 were evaluated for α-glucosidase inhibitory activity, except five compounds all derivatives showed good to moderate inhibitory potential in the range of IC50 = 0.28 ± 2.65 - 0.94 ± 2.20 μM. Among them, the most active compounds were 5, 8, 9, and 12 with IC50 values of 0.29 ± 4.63, 0.29 ± 0.93, 0.28 ± 3.65, and 0.28 ± 2.65, respectively. Furthermore, all these compounds were found to be non-toxic on human fibroblast cell lines (BJ cell lines). Kinetics study of compounds 8 and 9 revealed competitive type of inhibition with Ki values 2.79 ± 0.011 and 3.64 ± 0.012 μM, respectively. The binding interactions of synthetic compounds were also confirmed through molecular docking studies that indicated that compounds fit well in the active site of enzyme. Furthermore, a total of 30ns MD simulation was carried out for the most potent complexes of the series. The molecular dynamics study revealed that compound-8 and compound-12 were stable during the MD simulation.

Abstract
A library of 22 derivatives of 1,3,4-oxadiazole-2-thiol was synthesized, structurally characterized, and assessed for its potential to inhibit α-amylase, α-glucosidase, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and antioxidant activities. Most of the tested compounds demonstrated good to moderate inhibition potential; however, their activity was lower than that of the standard acarbose. Significantly, compound 3f exhibited the highest inhibition potential against α-glucosidase and α-amylase enzymes, with IC50 values of 18.52 ± 0.09 and 20.25 ± 1.05 µM, respectively, in comparison to the standard acarbose (12.29 ± 0.26; 15.98 ± 0.14 µM). Compounds also demonstrated varying degrees of inhibitory potential against AChE (IC50 = 9.25 ± 0.19 to 36.15 ± 0.12 µM) and BChE (IC50 = 10.06 ± 0.43 to 35.13 ± 0.12 µM) enzymes compared to the standard donepezil (IC50 = 2.01 ± 0.12; 3.12 ± 0.06 µM), as well as DPPH (IC50 = 20.98 ± 0.06 to 52.83 ± 0.12 µM) and ABTS radical scavenging activities (IC50 = 22.29 ± 0.18 to 47.98 ± 0.03 µM) in comparison to the standard ascorbic acid (IC50 = 18.12 ± 0.15; 19.19 ± 0.72). The kinetic investigations have demonstrated that the compounds exhibit competitive-type inhibition for α-amylase, noncompetitive-type inhibition for α-glucosidase and AChE, and mixed-type inhibition for BChE. Additionally, a molecular docking study was performed on all synthetic oxadiazoles to explore the interaction details of these compounds with the active sites of the enzymes.

Abstract
Background: Diabetes mellitus is a significant health disorder; therefore, researchers should focus on discovering new drug candidates. Methods: A series of indole-pyridine carbonitrile derivatives, 1-34, were synthesized through a one-pot multicomponent reaction and evaluated for antidiabetic and antioxidant potential. Results: In this library, 12 derivatives - 1, 2, 4, 5, 7, 8, 10-12, 14, 15 and 31 - exhibited potent inhibitory activities against α-glucosidase and α-amylase enzymes, in comparison to acarbose (IC50 = 14.50 ± 0.11 μM). Furthermore, kinetics, absorption, distribution, metabolism, excretion and toxicity and molecular docking studies were used to interpret the type of inhibition, binding energies and interactions of ligands with target enzymes. Conclusion: These results indicate that the compounds may be promising hits for controlling diabetes mellitus and its related complications.

Abstract
OBJECTIVE The growing bacterial resistance towards classical antibiotics demands the development of novel approaches for the effective treatment of potentially fatal bacterial infections in humans. Proteostasis is crucial for the survival of every living cell, as several important physiological functions depend on well-regulated proteostasis. Within bacteria, the regulation of proteostasis relies on AAA+ (Adenosine 5'-triphosphatases associated with diverse cellular activities), ATPases, such as the HslVU complex (heat shock locus gene products U and V), along with other proteases. The HslVU protease/chaperon complex is thought to be the progenitor of the eukaryotic proteasome that regulates proteostasis mostly in prokaryotes. This study aimed to determine the inhibitory potential of 3-substituted coumarin derivatives against Escherichia coli heat shock locus V (HslV) protease. MATERIALS AND METHODS In this study, twenty-three derivatives of 3-substituted coumarin were assessed for their inhibitory potential against E. coli HslV protease using both in-vitro and in-silico techniques. RESULTS Among all the tested compounds, US-I-64, US-I-66, US-I-67, and US-I-68 displayed notable inhibitory potential against the HslV protease, showing IC50 (half maximal inhibitory concentration) values ranging from 0.2 to 0.73 μM. Additionally, the inhibitory potential of these compounds against the eukaryotic proteasome was also evaluated using a separate in-silico study. It was found that these compounds did not bind with the proteasomal active site, suggesting no apparent side effects of these lead molecules. CONCLUSIONS These identified HslV protease inhibitors can be used for the development of novel and safer anti-bacterial drugs.

Abstract
Background: Quinoline and acyl thiourea scaffolds have major chemical significance in medicinal chemistry. Quinoline-based acyl thiourea derivatives may potentially target the urease enzyme. Materials & methods: Quinoline-based acyl thiourea derivatives 1-26 were synthesized and tested for urease inhibitory activity. Results: 19 derivatives (1-19) showed enhanced urease enzyme inhibitory potential (IC50 = 1.19-18.92 μM) compared with standard thiourea (IC50 = 19.53 ± 0.032 μM), whereas compounds 20-26 were inactive. Compounds with OCH3, OC2H5, Br and CH3 on the aryl ring showed significantly greater inhibitory potential than compounds with hydrocarbon chains of varying length. Molecular docking studies were conducted to investigate ligand interactions with the enzyme's active site. Conclusion: The identified hits can serve as potential leads against the drug target urease in advanced studies.

Abstract
Background: Researchers seeking new drug candidates to treat diabetes mellitus have been exploring bioactive molecules found in nature, particularly tetrahydropyridines (THPs). Methods: A library of THPs (1-31) were synthesized via a one-pot multicomponent reaction and investigated for their inhibition potential against α-glucosidase and α-amylase enzymes. Results: A nitrophenyl-substituted compound 5 with IC50 values of 0.15 ± 0.01 and 1.10 ± 0.04 μM, and a Km value of 1.30 mg/ml was identified as the most significant α-glucosidase and α-amylase inhibitor, respectively. Kinetic studies revealed the competitive mode of inhibition, and docking studies revealed that compound 5 binds to the enzyme by establishing hydrophobic and hydrophilic interactions and a salt bridge interaction with His279. Conclusion: These molecules may be a potential drug candidate for diabetes in the future.

Abstract
A library of 2-oxopyridine carbonitriles 1-34 was synthesized by regioselective nucleophilic substitution reactions. In the first step, a one-pot multicomponent reaction yield pyridone intermediates. The resulting pyridone intermediates were then reacted with phenacyl halides in DMF and stirred at 100 °C for an hour to afford the desired compounds in good yields. Structures of synthetic molecules were characterized by EI-MS, HREI-MS, 1H NMR, and 13C NMR, and all thirty-four (34) compounds were found to be new. All synthetic compounds were examined for antidiabetic and antioxidant potential. The compounds exhibited α-glucosidase inhibitory potential in the range of IC50 = 3.00 ± 0.11-43.35 ± 0.67 μM and α-amylase inhibition potential in the range of IC50 = 9.20 ± 0.14-65.56 ± 1.05 μM. Among the tested compounds, 1 showed the most significant α-glucosidase inhibitory activity, with an IC50 value of 3.00 ± 0.11 μM, while the most active compound against α-amylase was 6, with an IC50 value = 9.20 ± 0.14 μM. The kinetic studies and analysis indicated that the compounds followed the competitive mode of inhibition. In addition, the molecular docking studies showed the interaction profile of all molecules with the binding site residues of α-glucosidase and α-amylase enzymes.

Abstract
Herein, a library of novel pyridone derivatives 1-34 was designed, synthesized, and evaluated for α-amylase and α-glucosidase inhibitory as well as antioxidant activities. Pyridone derivatives 1-34 were synthesized via a one-pot multi-component reaction of variously substituted aromatic aldehydes, acetophenone, ethyl cyanoacetate, and ammonium acetate in absolute ethanol. Synthetic compounds 1-34 were structurally characterized by different spectroscopic techniques. Most of the tested compounds showed more promising inhibition potential than the standard acarbose (IC50 = 14.87 ± 0.16 µM) but compounds 13 and 12 were found to be the most potent compounds with IC50 values of 9.20 ± 0.14 µM and 3.05 ± 0.18 µM against α-amylase and α-glucosidase enzymes, respectively. Compounds 1-34 also displayed moderate antioxidant potential in the range of IC50 = 96.50 ± 0.45 to 189.98 ± 1.00 µM in comparison to the control butylated hydroxytoluene (BHT) (IC50 = 66.50 ± 0.36 µM), in DPPH radical scavenging activities. Additionally, all synthetic derivatives were subjected to a molecular docking study to investigate the interaction details of compounds 1-34 (ligands) with the active site of enzymes (receptors). These results indicate that the newly synthesized pyridone class may serve as promising lead candidates for controlling diabetes mellitus and as antioxidants.

Abstract
ABSTRACT. Ti(III) and (IV) hydrazide complexes were synthesized, characterized, and screened for their tyrosinase and lipoxygenase inhibitory and cytotoxic activities. The geometry of Ti(III) hydrazide complexes is tentatively assigned as octahedral. Magnetic moments were found around 1.7 B.M. and electronic spectral transition in the range of 495-518 nm. Evaluation of Ti(IV) and Ti(III) hydrazide complexes for tyrosinase and lipoxygenase inhibitory activities revealed varying inhibition potential. Hydrazide ligands were inactive against tyrosinase, while significant activity was observed against lipoxygenase (LOX). Good to moderate inhibition activity was observed by Ti(IV) and Ti(III) hydrazide complexes against both enzymes. At the same time, promising results were obtained for Ti(IV) hydrazide complexes against tyrosinase enzymes suggesting their broad application as tyrosinase inhibitors. Complex 4d possess negative inhibition, thus behaving as a tyrosinase activator. The docking results showed a good correlation between complex experimental activities and binding energies. Cytotoxic investigation revealed the non-toxicity of complexes against normal cells.

Abstract
OBJECTIVE Proteostasis is an important process occurring in all living cells and is highly indispensable for cell survival. The HslVU protease/chaperone complex's critical role in regulating proteostasis to maintain a healthy cellular proteome and its presence in pathogenic microbes made it an important drug target. This study aimed to identify small molecular inhibitors of the HslV protease. MATERIALS AND METHODS Herein, a library of small molecules belonging to the triazine and chromone families has been evaluated for their inhibitory potential against the E. coli HslV protease using both in silico and in vitro techniques. RESULTS Four compounds, i.e., SHS-II-123a, SHS-II-147a, US-IV-89, and US-IV-92, were identified as potential inhibitors of the HslV protease having IC50 values in the range of 0.1 to 0.32 µM. Additionally, these compounds' drug-likeness and ADMET profiles indicated their compatibility to be considered safer drug candidates. CONCLUSIONS To the best of our knowledge, this is the first report on small molecules having inhibitory effects on the HslVU complex. These identified compounds can be efficiently subjected to further investigations to develop novel and safer antimicrobial agents.

Abstract
A library of hydrazinyl thiazole-linked indenoquinoxaline hybrids 1-36 were synthesized via a multistep reaction scheme. All synthesized compounds were characterized by various spectroscopic techniques including EI-MS (electron ionization mass spectrometry) and 1H NMR (nuclear magnetic resonance spectroscopy). Compounds 1-36 were evaluated for their inhibitory potential against α-amylase, and α-glucosidase enzymes. Among thirty-six, compounds 2, 9, 10, 13, 15, 17, 21, 22, 31, and 36 showed excellent inhibition against α-amylase (IC50 = 0.3-76.6 μM) and α-glucosidase (IC50 = 1.1-92.2 μM). Results were compared to the standard acarbose (IC50 = 13.5 ± 0.2 μM). All compounds were also evaluated for their DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity and compounds 2, 9, 10, 17, 21, 31, and 36 showed (SC50 = 7.58-125.86 μM) as compared to the standard ascorbic acid (SC50 = 21.50 ± 0.18 μM). Among this library, compounds 9 and 10 with a hydroxy group on the phenyl rings and thiosemicarbazide bearing intermediate 21 were identified as the most potent inhibitors against α-amylase, and α-glucosidase enzymes. The remaining compounds were found to be moderately active. The molecular docking studies were conducted to understand the binding mode of active inhibitors and kinetic studies of the active compounds followed competitive modes of inhibition.

Abstract
The bacterial HslVU complex consists of two different proteins, i.e., the HslV protease and the HslU ATPase. The functional HslVU enzyme complex forms only when the HslU c-terminal helix is inserted into the cavity located between two adjacent HslV monomers in order to allosterically activate the HslV protease. Based on its essential role in maintaining microbial proteostasis as well its absence from human beings, it is considered a promising therapeutic target for designing antibacterial agents. The goal of the present study was to find out potential drug candidates that could over-activate the HslV protease and produce aberrant proteolysis in pathogenic bacteria. Derivatives of 3-substituted coumarin have been identified as potential HslV protease activators based on their highest docking scores, ideal interaction patterns, and significant in-vitro HslV activation potential. Their ED50 values were in the sub-micromolar range, i.e., 0.4-0.48µM. The conformational stability of the contacts between the HslV dimer and the active compounds was further confirmed by molecular dynamics studies. Correspondingly, the ADMET characteristics of these lead molecules considerably demonstrated their significant non-toxic drug-like abilities. This research not only identified small non-peptidic HslV protease activators but also improved the understanding of the mode of action of 3-substituted coumarin derivatives as antibacterials.

Abstract
Variety of 2-aryl quinoxaline derivatives 1-23 were synthesized in good yields, by reacting 1,2-phenylenediamine with varyingly substituted phenacyl bromides in the presence of pyridine catalyst. All molecules 1-23 were characterized by spectroscopic techniques and evaluated for their diverse biological potential against α-amylase (α-AMY), α-glucosidase (α-GLU), acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) enzymes. Synthetic derivatives possess enhanced inhibitory potential against all enzymes at nanomolar concentrations. In particular, compound 14 was found much superior with IC50 = 294.35, 198.21, 17.04, and 21.46 nM against α-AMY, α-GLU, AChE, and BChE, respectively, as compared to standard inhibitors. Furthermore, selected potent compounds, including 3, 4, 8, 14, 15, 17, and 18, were subjected to molecular docking studies to decipher the binding energies and interactions of ligands (synthetic molecules) with all four target enzymes.

Abstract
NADH and NADPH are labile coenzymes that undergo hydration by enzymatic reaction or by heat at 5,6 double bond, and convert into non-functional hydrates, NADHX and NADPHX, respectively. The NAD(P)H hydrate dehydratase enzyme catalyzes the dehydration of S-NADHX/S-NADPHX at the expense of ATP, and thus contributes in the nicotinamide nucleotide repair process. This enzyme is also known as "metabolite-proofreading enzyme". Herein, we report the molecular cloning and expression of this highly conserved enzyme of vancomycin-resistant Staphylococcus aureus (VRSA). Its functional and inhibition studies were performed for the first time by NMR spectroscopy. NMR studies showed the dehydration of S epimer of NADHX, in the presence of R-NADHX and cyc-NADHX, by NAD(P)H hydrate dehydratase. In addition, by employing the STD-NMR approach, a library of drugs and natural products (total 79) were evaluated for their binding interactions with the NAD(P)H hydrate dehydratase enzyme. Among them, seven compounds showed ligand-like interactions with the enzyme, and thus functional activity of the enzyme was again checked in the presence of each ligand. Compound 2 (Thiamine HCl) was found to fully inhibit the enzyme's function, and recognized as a potential inhibitor. Current study demonstrates that this enzyme deserves further studies as a potential drug target, as its inhibition can disrupt the normal metabolism of pathogenic VRSA.

Abstract
A two-step reaction method was used to synthesize a series of rhodanine-based Schiff bases (2-33) that were characterized using spectroscopic techniques. All compounds were assessed for α-amylase inhibitory and radical scavenging (DPPH and ABTS) activities. In comparison to the standard acarbose (IC50 = 9.08 ± 0.07 µM), all compounds demonstrated good to moderate α-amylase inhibitory activity (IC50 = 10.91 ± 0.08-61.89 ± 0.102 µM). Compounds also demonstrated significantly higher DPPH (IC50 = 10.33 ± 0.02-96.65 ± 0.03 µM) and ABTS (IC50 = 12.01 ± 0.12-97.47 ± 0.13 µM) radical scavenging activities than ascorbic acid (DPPH, IC50 = 15.08 ± 0.03 µM; ABTS, IC50 = 16.09 ± 0.17 µM). The limited structure-activity relationship (SAR) suggests that the position and nature of the substituted groups on the phenyl ring have a vital role in varying inhibitory potential. Among the series, compounds with an electron-withdrawing group at the para position showed the highest potency. Kinetic studies revealed that the compounds followed a competitive mode of inhibition. Molecular docking results are found to agree with experimental findings, showing that compounds reside in the active pocket due to the main rhodanine moiety.

Abstract
Aims:
Synthesis of bioactive compounds has antioxidant potential.
Background:
All aerobic bodies including human beings, have an antioxidant defense systems that protects them from oxidative damage, and many enzymes to remove or heal damaged molecules. However, this normal antioxidant mechanism can be incompetent, and hence dietary intakes of antioxidant compounds are important.
Objective:
Synthesis of isophthalate Schiff base derivatives 1-14 and screened for their antioxidant activities (DPPH, ferrous ion Fe2+ chelating and ferric Fe3+ reducing activities)
Method:
Schiff bases 1-14 were synthesized by two-step reaction scheme. First step was the esterification reaction of isophthalic acid followed by the hydrazinolysis of methyl isophthalate to afford isophthalic dihydrazide. Second step was the condensation reaction of isophthalic dihydrazide with a variety of benzaldehydes to afford Schiff bases 1-14. Synthetic compounds were characterized by spectroscopic techniques such as 1H-NMR and EI-MS.
Result:
Compounds were screened for their antioxidant activities (DPPH, ferrous ion Fe2+ chelating and ferric Fe3+ reducing activities). Most of the compounds showed significant antioxidant activities. A structure-activity relationship has also been discussed.
Conclusion:
Most of the synthetic isophthalate Schiff bases were found to be moderately active when screened for their antioxidant activities by three assays such as DPPH radical scavenging, ferrous ion-chelating and ferric reducing activities. These moderately active compounds can serve as lead molecules for further modification in the structure in order to identify more powerful antioxidant agents.

Abstract
AIMS Synthesis of bis-1,3,4-oxadiazole derivatives as novel and potential urease inhibitors. BACKGROUND Despite many important biological activities associated with oxadiazoles, they are still neglected by medicinal chemists for their possible urease inhibitory activity. Keeping in view the countless importance of urease inhibitors, we have synthesized a new library of substituted bis-oxadiazole derivatives (1-21) to evaluate their urease inhibitory potential. OBJECTIVE Synthesis of substituted bis-oxadiazole derivatives (1-21) to evaluate their urease inhibitory potential. METHOD Bis-1,3,4-oxadiazole derivatives 1-21 were synthesized through sequential reactions using starting material isophthalic acid. Esterification reaction was done by refluxing in methanol for 2 h in the presence of the catalytic amount of concentrated H2SO4 till dissolution. In the second step, dimethyl isophthalate and hydrazine hydrate in excess (1:5) were refluxed in methanol to afford isophthalic dihydrazide. Then, isophthalic dihydrazide was treated with different substituted benzaldehydes in a 1:2 ratio under acidic conditions Result: In vitro urease, the inhibitory activity of the synthesized compounds were evaluated and results demonstrated good activities with IC50 values in the range of 13.46 ± 0.34 to 74.45 ± 3.81 µM as compared to the standard thiourea (IC50 = 21.13 ± 0.415 µM). Most of the compounds were found to be more potent than the standard. The structure-activity relationship (SAR) suggested that the variations in the inhibitory activities of the compounds were due to different substitutions. Furthermore; in silico study was also performed. CONCLUSION Current study identified a new class of urease inhibitors. All synthetic compounds 1-21 showed potent as well as good to moderate urease inhibitory activities except 3. SAR suggested that hydroxy-bearing analogs were identified exceptionally good. Molecular docking revealed many important interactions made by compounds with the active site of the urease enzyme.

Abstract
The identification of novel compounds that can inhibit physiologically and metabolically important drug targets or enzymes has prime importance in medicinal chemistry. With this aim, a range of secnidazole esters 1-30 were synthesized under the heading of biology-oriented drug synthesis by the 1,1'-carbonyldiimidazole-mediated coupling reaction between secnidazole and varyingly benzoic acid derivatives. All compounds were screened for inhibitory activity against human carbonic anhydrase (hCA) I and II, acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and α-glucosidase. The results indicate that all the synthesized compounds showed potent inhibitory activities against all targets, as compared to the standard inhibitors, revealed by IC50 values. Ki values of the secnidazole derivatives 1-30 for hCA I, hCA II, AChE, BChE, and α-glucosidase enzymes were obtained in the ranges of 47.37-190.74, 44.38-198.21, 12.14-68.37, 8.04-61.53, and 7.78-45.91 nM, respectively. To assess the enzyme-ligand interactions, the optimized most active compounds 2, 3, 8, 9, 14, 17, and 23 were subjected to molecular docking studies with modeled AChE, BChE, hCA I, hCA II, and α-glucosidase enzymes, where several important and key interactions were monitored with amino acid residues of each target enzyme.

Abstract
Benzimidazole scaffolds are known to have a diverse range of biological activities and found to be antidiabetic and antioxidant. In this study, a variety of arylated benzimidazoles 1-31 were synthesized. Except for compounds 1, 6, 7, and 8, all are new derivatives. All compounds were screened for α-amylase inhibitory, 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. In vitro screening results revealed that all molecules demonstrated significant α-amylase inhibition with IC50 values of 1.86 ± 0.08 to 3.16 ± 0.31 μM as compared to standard acarbose (IC50 = 1.46 ± 0.26 μM). However, compounds showed significant ABTS and DPPH radical scavenging potentials with IC50 values in the range of 1.37 ± 0.21 to 4.00 ± 0.10 μM for ABTS and 1.36 ± 0.09 to 3.60 ± 0.20 μM for DPPH radical scavenging activities when compared to ascorbic acid with IC50 values of 0.72 ± 0.21 and 0.73 ± 0.05 μM for ABTS and DPPH radical scavenging potentials, respectively. Structure-activity relationship (SAR) was established after critical analysis of varying substitution effects on α-amylase inhibitory and radical scavenging (ABTS and DPPH) potentials. However, molecular docking was also performed to figure out the active participation of different groups of synthetic molecules during binding with the active pocket of the α-amylase enzyme.

Abstract
BACKGROUND A number of non-steroidal anti-inflammatory drugs (NSAIDs) including aspirin, indomethacin, ibuprofen, flufenamic acid, and phenylbutazone are being clinically used to treat inflammatory disorders. These NSAIDs are associated with serious side effects such as gastric ulceration, nephrotoxicity, and bleeding. Therefore, the identification of potent and safe therapy for inflammatory disorders is still of great interest to the medicinal chemist. METHODS A series of varyingly substituted benzoyl, acetyl, alkyl ester, and sulfonate ester substituted coumarins 1-64 were screened for the inhibition of ROS, generated from zymosan activated whole blood phagocytes, using luminol-enhanced chemiluminescence technique. RESULTS Among all tested compounds, 8 (IC50 = 65.0 ± 3.1 μM), 24 (IC50 = 41.8 ± 1.5 μM), 26 (IC50 = 10.6 ± 2.8 μM), 28 (IC50 = 20.9 ± 1.5 μM), and 41 (IC50 = 4.6 ± 0.3 μM) showed good anti- inflammatory potential as compared to standard antiinflammatory drug ibuprofen (IC50 = 54.3 ± 1.9 μM). Specifically, compounds 24, 26, 28, and 41 showed superior activity than standard antiinflammatory drug. Furthermore, compounds 12 (IC50 = 219.0 ± 1.4 μM), 14 (IC50 = 216.5 ± 6.2 μM), 16 (IC50 = 187.4 ± 2.2 μM), and 20 (IC50 = 196.2 ± 2.0 μM) showed moderate ROS inhibitory activity. Limited SAR study revealed that the hydroxy-substituted compound showed better ROS inhibition potential in case of 3-benzoyl and 3-ethylester coumarin derivatives. Whereas, chloro substitution was found to be important in case of 3-acetyl coumarin derivatives. Similarly, in case of sulfonate ester, chloro, and nitro groups especially at positions -4 and -3 of ring "R" played vital role in ROS inhibition. Furthermore, cytotoxicity of all active compounds was also checked on NIH-3T3 cell line. Compounds 12, 14, and 20 were found to be non-cytotoxic. Whereas, 8, 16, 24, 26, 28, and 41 were found to be very weak cytotoxic as compared to standard cycloheximide (IC50 = 0.13 ± 0.02 μM). CONCLUSION Identified ROS inhibitors offer the possibility of additional modifications that could give rise to lead structures for further research in order to obtain more potent, and safer antiinflammatory agent.

Abstract
N-Aryl-3,4-dihydroisoquinoline carbothioamide analogues 1-22 were synthesized by a simple one-step reaction protocol and subjected to in vitro urease inhibition studies for the first time. All compounds 1-22 were found active and showed significant to moderate urease inhibitory potential. Specifically, analogues 1, 2, 4, and 7 were identified to be more potent (IC50 = 11.2 ± 0.81-20.4 ± 0.22 μM) than the standard thiourea (IC50 = 21.7 ± 0.34 μM). The structure-activity relationship showed that compounds bearing electron-donating groups showed superior activity. Molecular docking study on the most active derivatives revealed a good protein-ligand interaction profile against the corresponding target with key interactions, including hydrogen bonding, hydrophobic, and π-anion interactions.

Abstract
Background:
A number of synthetic scaffolds, along with natural products, have been
identified as potent antioxidants. The present study deals with the evaluation of varyingly substituted,
medicinally distinct class of compounds “chalcones and bis-chalcones” for their antioxidant potential.
Methods:
In vitro radical scavenging activities were performed on a series of synthetic chalcones 1-
13 and bis-chalcones 14-18.
Results:
All molecules 1-18 revealed a pronounced 2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2ʹ-
azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicals scavenging potential in the
ranges of IC50s = 0.58 ± 0.14 - 1.72 ± 0.03 and 0.49 ± 0.3 - 1.48 ± 0.06 μM, respectively. Ascorbic
acid (IC50s = 0.5 ± 0.1 and 0.46 ± 0.17 μM for DPPH and ABTS, respectively) was used as a standard
radical scavenger.
Conclusion:
Structure-activity relationship (SAR) revealed an active participation of various
groups, including -SMe and -OMe in scavenging activity.

Abstract
A variety of dihydroquinazolin-4(1H)-one derivatives (1-37) were synthesized via "one-pot" three-component reaction scheme by treating aniline and different aromatic aldehydes with isatoic anhydride in the presence of acetic acid. Chemical structures of compounds were deduced by different spectroscopic techniques including EI-MS, HREI-MS, 1H-, and 13C-NMR. Compounds were subjected to α-amylase and α-glucosidase inhibitory activities. A number of derivatives exhibited significant to moderate inhibition potential against α-amylase (IC50 = 23.33 ± 0.02-88.65 ± 0.23 μM) and α-glucosidase (IC50 = 25.01 ± 0.12-89.99 ± 0.09 μM) enzymes, respectively. Results were compared with the standard acarbose (IC50 = 17.08 ± 0.07 μM for α-amylase and IC50 = 17.67 ± 0.09 μM for α-glucosidase). Structure-activity relationship (SAR) was rationalized by analyzing the substituents effects on inhibitory potential. Kinetic studies were implemented to find the mode of inhibition by compounds which revealed competitive inhibition for α-amylase and non-competitive inhibition for α-glucosidase. However, in silico study identified several important binding interactions of ligands (synthetic analogues) with the active site of both enzymes.

Abstract
(E)-3-(2-Benzylidenehydrazinyl)-5,6-diphenyl-1,2,4-triazines analogs 1-27 were synthesized by multi-step reaction scheme and subjected to in vitro inhibitory screening against α-amylase and α-glucosidase enzymes. Out of these twenty-seven synthetic analogs, ten compounds 14-17, 19, and 21-25 are structurally new. All compounds exhibited good to moderate inhibitory potential in terms of IC50 values ranging (IC50 = 13.02 ± 0.04-46.90 ± 0.05 µM) and (IC50 = 13.09 ± 0.08-46.44 ± 0.24 µM) in comparison to standard acarbose (IC50 = 12.94 ± 0.27 µM and 10.95 ± 0.08 µM), for α-amylase and α-glucosidase, respectively. Structure-activity relationship indicated that analogs with halogen substitution(s) were found more active as compared to compounds bearing other substituents. Kinetic studies on most active α-amylase and α-glucosidase inhibitors 5, 7, 9, 15, 24, and 27, suggested non-competitive and competitive types of inhibition mechanism for α-amylase and α-glucosidase, respectively. Molecular docking studies predicted the good protein-ligand interaction (PLI) profile with key interactions such as arene-arene, H-<, <-<, and <-H etc., against the corresponding targets.

Abstract
Background:
Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, aspirin,
indomethacin, flufenamic acid and phenylbutazone are used to treat most of the inflammatory
disorders. These NSAIDs are also associated with serious side effects including gastric ulceration,
nephrotoxicity, and bleeding, mainly due to acidic nature. Hence, there is a need to identify highly
potent and safer treatment for inflammatory disorders.
Methods:
Herein, synthetic hydrazinyl thiazole substituted coumarins and chromones 1-48 were
evaluated for ROS inhibitory activity. ROS were generated from zymosan activated whole blood
phagocytes.
Results:
Among all tested compounds, compounds 1 (IC50 = 38.3 ± 7.1 μM), 2 (IC50 = 5.7 ±
0.2 μM), 5 (IC50 = 28.3 ± 3.5 μM), 23 (IC50 = 12.5 ± 3.1 μM), 27 (IC50 = 32.8 ± 1.1 μM), 39 (IC50 =
20.2 ± 1.6 μM), and 42 (IC50 = 43.2 ± 3.8 μM) showed potent ROS inhibition as compared to
standard ibuprofen (IC50 = 54.3 ± 1.9 μM). Whereas, compounds 3 (IC50 = 134.7 ± 1.0 μM), 16
(IC50 = 75.4 ± 7.2 μM), 24 (IC50 = 102.4 ± 1.0 μM), and 31 (IC50 = 86.6 ± 1.5 μM) were found to be
moderately active. Compounds 1, 2, 5, 23, 27, 39, and 42, having potent ROS inhibitory activity
were also screened for their nitric oxide (NO) inhibition. Cytotoxicity was also checked for all active
compounds on NIH-3T3 cell line. Cyclohexamide (IC50 = 0.13 ± 0.02 μM) was used as standard.
Conclusion:
Identified active compounds from these libraries may serve as lead candidates for future
research in order to obtain a more potent, and safer anti-inflammatory agent.

Abstract
Background:
Previous identification of N,N-diethylthiobarbiturates as potential
α-glucosidase inhibitory potential prompted us to investigate the antiglycation activity of these
synthetic compounds (1-25) in order to identify the lead candidates for their possible antidiabetic
potential.
Methods:
Synthetic compounds (1-25) were evaluated for their antiglycation activity using Bovine
Serum Albumin assay (BSA).
Results:
Compounds exhibited varying degree of inhibition in the range of IC50 = 61.16 ± 2.3 - 656.71
± 2.5 µM as compared to the standard rutin (IC50 = 294.5 ± 1.50 µM). Among the twenty five
synthetic molecules, seven compounds showed good activity in comparison with the standard.
Compound 4 (IC50 = 61.16 ± 2.3 µM) having hydroxy substituents was the most active molecule of
the library. This study revealed that compound 4 has dual acting antidibetic molecule.
Conclusion:
In conclusion, the synthetic N,N-diethylthiobarbiturates can act as lead molecules.
Furthermore, synthetic variations on N,N-diethylthiobarbituric acid moiety might be helpful in
generating a library of potential anti diabetic agent. Especially, compound 4 has been identified as
dual acting antidiabetic agent i.e. α-glucosidase inhibitor and antiglycating agent.

Abstract
Novel ibuprofen derivatives 1-19 including ibuprofen hydrazide 1, and substituted thiourea derivatives 2-19 were synthesized and characterized by EI-MS, FAB-MS, HREI-MS, HRFAB-MS, 1H-, and 13C-NMR spectroscopic techniques. The synthetic molecules 1-19 were examined for their in vitro urease inhibition and were found to display a diversified degree of inhibitory potential in the range of IC50 = 2.96-178 μM as compared to the standard thiourea (IC50 = 21.32 ± 0.22 μM). Out of nineteen, thirteen derivatives 2-4, 6, 7, 9, 11-15, 17, and 18 demonstrated remarkable inhibitory activity with IC50 values of 2.96 ± 1.11 to 16.1 ± 1.07 μM, compound 5 exhibited moderate inhibition with IC50 value of 37.3 ± 0.41 μM, whereas, compounds 1, 8, and 10 demonstrated weak inhibition against urease enzyme. Almost all structural features are participating in the activity; however, limited structure-activity relationship was discussed on the basis of different structural features, i.e., different functional groups and their positions at aryl part. In addition, molecular docking study was performed in order to understand the ligands binding interactions with the active site of urease enzyme.

Background:Albendazole is a drug, belongs to the family of benzimidazole, and used as an anthelmintic agent in both human and veterinary medicine. It is marketed as Albenza which is used for the treatment of a variety of parasitic worm infestations such as roundworms, tapeworms, and flukes. In recent past, we have reported various classes of compounds as anti-glycating agents, in continuation of Biology-oriented Drug Synthesis (BIODS), seventeen albendazole derivatives 2-18 were synthesized evaluated for yeast glucose uptake activity.Methods:In the present study, Albendazole (2 g, 7.5 mmol), potassium hydroxide (3 g) were dissolved in ethanol (50 mL) into a 250 mL round-bottomed flask and refluxed for 48 h. TLC (ethyl acetate: hexane, 6:4) was monitored in order to check the reaction progress. After completion, the reaction mixture was dried under air and washed with an excess of distilled water. Precipitates were dried and crystallized from ethanol. The product was characterized by EI-MS and 1H-NMR.Results:Our present study showed that all compounds showed a varying degree of yeast glucose uptake activity ranging between IC50 = 51.41-258.40 µM, compared with standard metronidazole (IC50 = 41.86 ± 0.09 µM). This study has identified a series of potential leads for anti-glycating agents.Conclusion:Biology-oriented drug synthesis and in vitro yeast glucose uptake activity of albendazole derivatives gave rise to a number of lead molecule such as 3 (IC50 = 59.37 ± 0.26 µM), 5 (IC50 = 59.70 ± 0.32 µM), 6 (IC50 = 60.78 ± 0.54 µM), 8 (IC50 = 54.61 ± 0.20 µM), 16 (IC50 = 56.57 ± 0.04 µM) and 14 (IC50 = 51.41 ± 1.25 µM).

Abstract
Background:
Tyrosinase enzyme is one of the important targets to reduce melanoma and
other skin disorders. Standard inhibitors of tyrosinase enzyme including arbutin and kojic acid are
less effective. Some NSAIDs such as acetylsalicylic acid, mefanamic acid, and diclofenac are known
to possess inhibitory potential against melanogenesis. The current study deals with the screening of
tyrosinase inhibitory potential of S-naproxen derivatives.
Methods:
Synthetic S-naproxen derivatives 1-33 were evaluated for tyrosinase inhibitory activity in
vitro.
Results:
Six compounds 2, 8, 9, 20, 21, and 29 showed good to moderate activity in the range of
(IC50 = 21.05 ± 0.9-53.22 ± 0.7 µM) as compared to the standard kojic acid (IC50 = 16.9 ± 1.3 µM).
Compound 9 (IC50 = 21.05 ± 0.9 µM) was found to be significantly active and showed activity close
to the standard. Compounds 2 (IC50 = 33.23 ± 1.1 µM), 8 (IC50 = 42.10 ± 1.0 µM), 20 (IC50 = 35.40
± 0.4 µM), 21 (IC50 = 41.01 ± 0.6 ±M), and 29 (IC50 = 53.22 ± 0.7 µM) were found to be moderately
active. Structure-activity relationship (SAR) was rationalized on the basis of different substituents
and functionalities present on the main scaffold.
Conclusion:
This study has identified a number of compounds derived from S-naproxen with
comparable tyrosinase inhibitory activity.

Abstract
Background:Diabetes is the primary cause of fatality and disability all over the world, in recent past, we have reported various classes of compounds as anti-glycating agents and we have also reported benzimidazole and benzothiazole derivatives as a potential class of anti-glycating agents. This encouraged us to evaluate the pyridinyl benzimidazole/pyridinyl benzothiazole derivatives 1-27 for yeast glucose uptake activity.Methods:In the present study, an equimolar mixture of pyridine carboxaldehyde derivatives (1 mmol) and sodium metabisulphite (1 mmol) in DMF (10 mL) was stirred for 10 to 15 min, followed by addition of o-phenylene diamine/2-aminothiophenol (1 mmol) into it and refluxed for 3 h. The progress of the reaction was monitored by TLC. After completion, the reaction mixture was poured into crushed ice. Precipitates were formed which were collected by filtration to produce compounds 1-27 in good yields. Recrystallization from methanol yielded pure crystals.Results:Our present study showed that all compounds showed a varying degree of yeast glucose uptake activity in the range IC50 = 36.43-272.20 µM, compared to standard metronidazole (IC50 = 41.86 ± 0.09 µM). Compounds 5 (IC50 = 38.14 ± 0.17 µM), 6 (IC50 = 40.23 ± 0.20 µM), and 7 (IC50 = 36.43 ± 0.02 µM) showed an excellent yeast glucose uptake activity better than the standard.Conclusion:Pyridinyl benzimidazole/pyridinyl benzothiazole derivatives 1-27 were synthesized, structurally characterized, and evaluated for in vitro yeast glucose uptake activity. Compounds 5 (IC50 = 38.14 ± 0.17 µM), 6 (IC50 = 40.23 ± 0.20 µM), and 7 (IC50 = 36.43 ± 0.02 µM) demonstrated potent yeast glucose uptake activity as compared to standard metronidazole (IC50 = 41.86 ± 0.09 µM). This study identified a number of potential lead molecules which can be helpful in lowering the blood glucose level in hyperglycemia.

Abstract
Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, 1H-, and 13C NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for α-glucosidase and α-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 μM against α-glucosidase and α-amylase enzymes, respectively. The synthetic compounds were divided into two categories "A" and "B", in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 ± 1.31 μM), (IC50 = 2.5 ± 1.21 μM), 36 (IC50 = 2.12 ± 1.35 μM), (IC50 = 2.21 ± 1.08 μM), and 37 (IC50 = 2.00 ± 1.22 μM), (IC50 = 2.04 ± 1.4 μM) with chloro substitution/s at aryl ring were found to be most active against α-glucosidase and α-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against α-amylase and non-competitive mode of inhibition against α-glucosidase enzyme.

Abstract
BACKGROUND Results of our previous studies on antiglycation activity, and the noncytotoxicity of 2-mercapto benzothiazoles, encouraged us to further widen our investigation towards the identification of leads against diabetes mellitus. METHODS 33 derivatives of 2-mercapto benzothiazoles 1-33 were evaluated for in vitro α- glucosidase inhibitory activity. Mode of inhibition was deduced by kinetic studies. To predict the interactions of 2-mercapto benzothiazole derivatives 1-33 with the binding pocket of α-glucosidase enzyme, molecular docking studies were performed on the selected inhibitors. RESULTS Compounds 2-4, 6-7, 9-26, 28 and 30 showed many folds potent α-glucosidase inhibitory activity in the range of IC50 = 31.21-208.63 μM, as compared to the standard drug acarbose (IC50 = 875.75 ± 2.08 μM). It was important to note that except derivative 28, all other derivatives were also found previously to have antiglycating potential in the range of IC50 = 187.12-707.21 μM. CONCLUSION A number of compounds were identified as dual nature as antiglycating agent and α- glucosidase inhibitors. These compounds may serve as potential lead candidates for the management of diabetes mellitus.

Abstract
Background: Alkaline Phosphatase (AP) is a physiologically important metalloenzyme
that belongs to a large family of ectonucleotidase enzymes. Over-expression of tissue non-specific
alkaline phosphatase has been linked with ectopic calcification including vascular and aortic calcification.
In Vascular Smooth Muscles Cells (VSMCs), the high level of Reactive Oxygen Species
(ROS) resulted in the up-regulation of TNAP. Accordingly, there is a need to identify highly potent
and selective inhibitors of APs for treatment of disorders related to hyper activity of APs.
</P><P>
Methods: Herein, a series of coumarinyl alkyl/aryl sulfonates (1-40) with known Reactive Oxygen
Species (ROS) inhibition activity, was evaluated for alkaline phosphatase inhibition against human
Tissue Non-specific Alkaline Phosphatase (hTNAP) and Intestinal Alkaline Phosphatase (hIAP).
</P><P>
Results: With the exception of only two compounds, all other compounds in the series exhibited
excellent AP inhibition. For hIAP and hTNAP inhibition, IC50 values were observed in the range
0.62-23.5 µM, and 0.51-21.5 µM, respectively. Levamisole (IC50 = 20.21 ± 1.9 µM) and Lphenylalanine
(IC50 = 100.1 ± 3.15 µM) were used as standards for hIAP and hTNAP inhibitory
activities, respectively. 4-Substituted coumarinyl sulfonate derivative 23 (IC50 = 0.62 ± 0.02 µM)
was found to be the most potent hIAP inhibitor. Another 4-substituted coumarinyl sulfonate derivative
16 (IC50 = 0.51 ± 0.03 µM) was found to be the most active hTNAP inhibitor. Some of the
compounds were also found to be highly selective inhibitors of APs. Detailed Structure-Activity
Relationship (SAR) and Structure-Selectivity Relationship (SSR) analysis were carried out to identify
structural elements necessary for efficient and selective AP inhibition. Molecular modeling and
docking studies were carried out to rationalize the most probable binding site interactions of the
inhibitors with the AP enzymes. In order to evaluate drug-likeness of compounds, in silico ADMETox
evaluation was carried out, most of the compounds were found to have favorable ADME profiles
with good predicted oral bioavailability. X-ray crystal structures of compounds 38 and 39 were
also determined.
</P><P>
Conclusion: Compounds from this series may serve as lead candidates for future research in order
to design even more potent, and selective inhibitors of APs.
