Abstract
The rational design of novel thiazolo[2,3-c][1,2,4]triazole derivatives was carried out based on previously identified antitubercular hit molecule H127 for discovering potent compounds showing antimicrobial activity. The designed compounds were screened for their binding efficacies against the antibacterial drug target enoyl-[acyl-carrier-protein] reductase, followed by prediction of drug-likeness and ADME properties. The designed analogues were chemically synthesized, characterized by spectroscopic techniques, followed by evaluation of antimicrobial activity against bacterial and fungal strains, as well as antitubercular activity against M. tuberculosis and M. bovis strains. Among the synthesized compounds, five compounds, 10, 11, 35, 37 and 38, revealed antimicrobial activity, albeit with differential potency against various microbial strains. Compounds 10 and 37 were the most active against S. mutans (MIC: 8 μg/mL), while compounds 11 and 37 showed the highest activity against B. subtillis (MIC: 16 μg/mL), whereas compounds 10, 11 and 37 displayed activities against E. coli (MIC: 16 μg/mL). Meanwhile, compounds 10 and 35 depicted activities against S. typhi (MIC: 16 μg/mL) and compound 10 showed antifungal activity against C. albicans (MIC: 32 μg/mL). The current study has identified two broad-spectrum antibacterial hit compounds (10 and 37). Further structural investigation on these molecules is underway to enhance their potency.

Abstract
The present study was intended for the identification of secondary metabolites in acetone extract of the lichen Hypotrachyna cirrhata using UPLC-ESI-QToF-MS/MS and the detection of bioactive compounds. This study led to the identification of 22 metabolites based on their MS/MS spectra, accurate molecular masses, molecular formula from a comparison of the literature database (DNP), and fragmentation patterns. In addition, potent antioxidant and α-glucosidase inhibitory potentials of acetone extract of H. cirrhata motivated us to isolate 10 metabolites, which were characterized as salazinic acid (11), norlobaridone (12), atranorin (13), lecanoric acid (14), lichesterinic acid (15), protolichesterinic acid (16), methyl hematommate (17), iso-rhizonic acid (18), atranol (19), and methylatratate (20) based on their spectral data. All these isolates were assessed for their free radicals scavenging, radical-induced DNA damage, and intestinal α-glucosidase inhibitory activities. The results indicated that norlobaridone (12), lecanoric acid (14), methyl hematommate (17), and atranol (19) showed potent antioxidant activity, while depsidones (salazinic acid (11), norlobaridone (12)) and a monophenolic compound (iso-rhizonic acid, (18)) displayed significant intestinal α-glucosidase inhibitory activities (p < 0.001), which is comparable to standard acarbose. These results were further correlated with molecular docking studies, which indicated that the alkyl chain of norlobaridione (12) is hooked into the finger-like cavity of the allosteric pocket; moreover, it also established Van der Waals interactions with hydrophobic residues of the allosteric pocket. Thus, the potency of norlobaridone to inhibit α-glucosidase enzyme might be associated with its allosteric binding. Also, MM-GBSA (Molecular Mechanics-Generalized Born Surface Area) binding free energies of salazinic acid (11) and norlobaridone (12) were superior to acarbose and may have contributed to their high activity compared to acarbose.

Abstract
(+)-Usnic acid (UA), a natural dibenzofuran derivative, abundantly produced by lichens and possess wide number of biomedical applications including antibacterial, anti-inflammatory, anti-oxidant and anticancer activities. In the present study, as series of usnic acid derivatives (3a-3i) were synthesised using Mannich reaction assessed for their antioxidant, α-glucosidase, and anticancer activities. The in vitro antioxidant activity showed that compound 3d displayed potent antioxidant activity by scavenging the activities of DPPH and ABTS+. The compounds 3d and 3e showed potent cytotoxic activity against HepG2 cancer cells by arresting the cell cycle at S phase and regulating the Bax/BcL2 expression and subsequently induce the apoptosis. Overall, the results clearly indicated that (+)-usnic acid derivatives bearing secondary amines are useful scaffolds for the development of drug candidates for treatment of oxidative stress mediated cancer and metabolic disorders.

Abstract
Tumor protein D52 (TPD52) is a proto-oncogene overexpressed in prostate cancer (PCa) due to gene amplification and it is involved in the cancer progression of many cancers including PCa. However, the molecular mechanisms underlying the role of TPD52 in cancer progression are still under investigation. In this study, we report that the activation of AMP-activated protein kinase (AMPK) by AICAR (5-Aminoimidazole-4-carboxamide ribonucleotide) inhibited the LNCaP and VCaP cells growth by silencing TPD52 expression. Activation of AMPK inhibited the proliferation and migration of LNCaP and VCaP cells. Interestingly, AICAR treatment to LNCaP and VCaP cells led to the downregulation of TPD52 via activation of GSK3β by a decrease of inactive phosphorylation at Ser9. Moreover, in AICAR treated LNCaP cells, inhibition of GSK3β by LiCl attenuated downregulation of TPD52 indicating that AICAR acts via GSK3β. Furthermore, we found that TPD52 interacts with serine/threonine kinase 11 or Liver kinase B1 (LKB1) a known tumor suppressor and an upstream kinase for AMPK. The molecular modeling and MD simulations indicates that the interaction between TPD52 and LKB1 leads to inhibition of the kinase activity of LKB1 as its auto-phosphorylation sites were masked in the complex. Consequently, TPD52-LKB1 interaction may lead to inactivation of AMPK. Moreover, overexpression of TPD52 is found to be responsible for the reduction of pLKB1 (Ser428) and pAMPK (Thr172). Therefore, TPD52 may be playing its oncogenic role via suppressing the AMPK activation. Altogether, our results revealed a new mechanism of PCa progression in which TPD52 overexpression inhibits AMPK activation by interacting with LKB1. These results support that the use of AMPK activators and/or small molecules that could disrupt the TPD52-LKB1 interaction might be useful to suppress PCa cell growth. TPD52 interacts LKB1 and interfere with activation of AMPK in PCa cells.

Abstract
WEE1 is a checkpoint kinase critical for mitotic events, especially in cell maturation and DNA repair. Most cancer cells' progression and survival are linked with elevated levels of WEE1 kinase. Thus, WEE1 kinase has become a new promising druggable target. A few classes of WEE1 inhibitors are designed by rationale or structure-based techniques and optimization approaches to identify selective acting anticancer agents. The discovery of the WEE1 inhibitor AZD1775 further emphasized WEE1 as a promising anticancer target. Therefore, the current review provides a comprehensive data on medicinal chemistry, synthetic approaches, optimization methods, and the interaction profile of WEE1 kinase inhibitors. In addition, WEE1 PROTAC degraders and their synthetic procedures, including a list of noncoding RNAs necessary for regulation of WEE1, are also highlighted. From the standpoint of medicinal chemistry, the contents of this compilation serve as an exemplar for the further design, synthesis, and optimization of promising WEE1-targeted anticancer agents.

Abstract
Evolution of new variants of SARS-CoV-2 warrant the need for the continued efforts in identifying target-oriented new drugs. Dual targeting agents against MPro and PLPro not only overcome the incomplete efficacy but also the drug resistance, which is common problem. Since both these are cysteine proteases, we designed 2-chloroquinoline based molecules with additional imine moiety in the middle as possible nucleophilic warheads. In the first round of design and synthesis, three molecules (C3, C4 and C5) inhibited (Ki < 2 μM) only MPro by binding covalently to C145 and one molecule (C10) inhibited both the proteases non-covalently (Ki < 2 μM) with negligible cytotoxicity. Further conversion of the imine in C10 to azetidinone (C11) improved the potency against both the enzymes in the nanomolar range (820 nM against MPro and 350 nM against PLPro) with no cytotoxicity. Conversion of imine to thiazolidinone (C12), reduced the inhibition by 3-5 folds against both the enzymes. Biochemical and computational studies suggest that C10-C12 bind in the substrate binding pocket of MPro and in the BL2 loop of the PLPro. Since these dual inhibitors have least cytotoxicity, they could be further explored as therapeutics against the SARS-CoV-2 and other analogous viruses.

Abstract
Most of the existing DENV entry inhibitors were discovered through structure-based, high-throughput screening techniques and optimization approaches by aiming β-OG pocket. However, the class of precise chemical scaffolds with superior antiviral activity targeting the early stages of virus infection that is considered to be beneficial in therapeutics and is still in process. In this study, ligand-based pharmacophore modeling using existing DENV entry inhibitors provided two best models, AADRR-2 and AAADR-2 (A- accepter, D- donor, R-ring) to screen public and DrugBank datasets. Further, approximately 36000 molecules were filtered using Zinc13 by employing the ideal validated models. Additionally, using β-OG binding pocket as target site, molecular docking experiments including induced-fit studies were conducted that provided further structurally divergent ligands. Moreover, the refined list of preferential hits were filtered out based on the best fitness score, binding energy and interaction paradigm, among them fused pyrimidine, hydrazone and biphenyl core comprising scaffolds were identified possessing profound interaction profile with key amino acid residues, ALA-50, GLN-200, PHE-193 and PHE-279 in 100 ns MD simulations. Additionally, the search for similar chemical fingerprints from DrugBank library was also carried out and Eltrombopag (Promacta/Revolade® prescribed in thrombocytopenia) was identified as a preferential β-OG pocket binder. The identified pyrazole-based hydrazone class of drug, Eltrombopag is in phase II clinical trials employed to treat dengue-mediated thrombocytopenia.Communicated by Ramaswamy H. Sarma.

Abstract
Lupeol is one of the most important metabolite in the class of terpenoids and possess excellent anticancer, anti-inflammatory, anti-diabetic activities etc. In the present study, the different thiazoles and oxazoles bearing lupeol derivatives were prepared to enhance their biological activity. Initially, the in vitro cytotoxic activity results showed that the synthesized lupeol derivatives (9a-9j and 10a-10e) showed significant activity against various cancer cells and the compounds 9h and 10b exhibited excellent activity against CAL27 cells. Further, these compounds 9h and 10b arrest the cell cycle at S phase and induce the late apoptosis in CAL27 cells by downregulating the BcL2 and vimentin expression and upregulating the Bax gene expression. Moreover, the lupeol derivatives showed dose-dependent anti-inflammatory activity by inhibiting the secretion of IL-6 cytokines in LPS-induced Raw 264.7 cells. Together, these results clearly indicated that the thiazoles and oxazoles bearing lupeol derivatives can used as chemotherapeutic drugs against cancer and inflammatory diseases.

Abstract
A series of novel nimbolide derivatives bearing various substitutions on 28th position was designed and synthesized using Sonogashira (2a-2p) and Glaser coupling (3a-3e) reactions. The synthesized derivatives were assessed for in vitro cytotoxic activity against four different human cancer cell lines (A549 cells, MCF-7 cells, MDA-MB-231 cells, and HCT15 cells) and normal cell line (HEK cells) using MTT assay. Among the screened derivatives, the compound 3a showed potent activity against A549 cells with IC50 value of 0.23 μM as comparing with parent molecule 1 (1.48 μM) and the standard drug doxorubicin (0.82 μM). As well, the flow cytometry analysis confirmed that the compounds 1 and 3a arrest the cell cycle progress at S phase and induce the early apoptosis in the lung cancer. The qRT-PCR analysis revealed that the compounds 1 and 3a downregulate the BcL2 expression and upregulates the Bax gene expression level in A549 cells. The strong binding affinity of the compounds 1 and 3a with BcL2 was also confirmed using molecular docking analysis. Together, the results suggested that the compound 3a is a promising anticancer agent against lung cancer is deserved for further investigation.

Abstract
A series of 2-heteroaryl benzimidazole-chalcone hybrids were synthesized and the anticancer
activity was estimated by MTT assay in human breast, lung, colon, and ovarian cancer cell lines. The
biological results indicate that the compounds showed good anticancer activity with IC50 value in the
range of 0.056-19.5 μM. Compound 11b with hexa methoxy groups, bearing three methoxy groups on
each terminal aryl ring exhibited a significant IC50 value (56 nM) against human breast carcinoma cells,
which is 37 times higher potency in comparison with the reference Etoposide. Further compounds substituted
variably with methoxy and nitro groups on the phenyl ring of chalcone showed more promising
anticancer activity than the compounds with unsubstituted phenyl ring or variably alkyl-substituted phenyl
ring of chalcone. The molecular docking results indicate that the synthesized compounds bind in the
active site of Abl tyrosine kinase, the target of anticancer drug Imatinib. The present study provides the
synergistic effect of hybrids, benzimidazole-chalcones as potential anticancer agents that will aid in the
discovery of new anticancer agents.

Abstract
This review provides the feasible literature on drug discovery through ML tools and techniques that are enforced in every phase of drug development to accelerate the research process and deduce the risk and expenditure in clinical trials. Machine learning techniques improve the decision-making in pharmaceutical data across various applications like QSAR analysis, hit discoveries, de novo drug architectures to retrieve accurate outcomes. Target validation, prognostic biomarkers, digital pathology are considered under problem statements in this review. ML challenges must be applicable for the main cause of inadequacy in interpretability outcomes that may restrict the applications in drug discovery. In clinical trials, absolute and methodological data must be generated to tackle many puzzles in validating ML techniques, improving decision-making, promoting awareness in ML approaches, and deducing risk failures in drug discovery.

Abstract
Cancer is one of the leading causes of death. The aim of the present study was to synthesize
and investigate the anticancer and antioxidant activities of some 3,5-bis(substituted benzylidene)-
1-ethylpiperidin-4-one analogues (4a-g).
The 3,5-bis(substituted benzylidene)-1-ethylpiperidin-4-one analogues (4a-g) were prepared from
the precursor, piperidin-4-one hydrochloride (1). The initial step involved the synthesis of intermediates,
3,5-bis(substituted benzylidene)piperidin-4-one analogues (3a-g) followed by their ethylation
with C2H5I in acetone and K2CO3 to obtain the title compounds (4a-g). The Fourier transform
infrared (FTIR), nuclear magnetic resonance (1H & 13C NMR), mass spectrometry and microanalysis
were used to characterize the title compounds (4a-g). All the compounds were further
evaluated for their anticancer activity by SRB assay and NCI US protocol, while the antioxidant
activity was evaluated by DPPH free radical assay. All the title compounds (4a-g) were subjected
to molecular docking studies against EGRF tyrosine kinase, a potential target for anticancer agents,
to study the possible mode of interaction of our compounds with the molecular target.
:
The compound 4g showed significant anticancer activity with GI50 of 28.2 μM against MCF-7
(Breast cancer cell line). The antioxidant activity of compound 4g (IC50 = 14.98±0.91 μM) was
found to be comparable to the standard drug ascorbic acid. The binding modes of compounds 4a-g
against the molecular target EGFR tyrosine kinase were also studied. The structure-activity relationship
(SAR) was also studied.

Abstract
We describe in this paper the synthesis of a novel series of anilino-2-quinazoline derivatives. These compounds have been screened against a panel of eight mammalian kinases and in parallel they were tested for cytotoxicity on a representative panel of seven cancer cell lines. One of them (DB18) has been found to be a very potent inhibitor of human "CDC2-like kinases" CLK1, CLK2 and CLK4, with IC50 values in the 10-30 nM range. Interestingly, this molecule is inactive at 100 μM on the closely related "dual-specificity tyrosine-regulated kinase 1A" (DYRK1A). Extensive molecular simulation studies have been performed on the relevant kinases to explain the strong affinity of this molecule on CLKs, as well as its selectivity against DYRK1A.

Abstract
Colorectal cancer (CRC) is one of the major causes of carcinogenic mortality in numbers only after lung and breast cancers. The mutations in adenomatous polyposis coli (APC) gene leads to formation of colorectal polyps in the colonic region and which develop as a malignant tumour upon coalition with patient related risk factors. The protein-protein interaction (PPI) of APC with Asef (A Rac specific guanine nucleotide exchange factor) overwhelms the patient's conditions by rapidly spreading in the entire colorectal region. Most mutations in APC gene occur in mutated cluster region (MCR), where it specifically binds with the cytosolic β-catenin to regulate the Wnt signalling pathway required for CRC cell adhesion, invasion, progression, differentiation and stemness in initial cell cycle phages. The current broad spectrum perspective is attempted to elaborate the sources of identification, development of selective APC inhibitors by targeting emopamil-binding protein (EBP) & dehydrocholesterol reductase-7 & 24 (DHCR-7 & 24); APC-Asef, β-catenin/APC, Wnt/β-catenin, β-catenin/TCF4 PPI inhibitors with other vital Wnt signal cellular proteins and APC/Pol-β interface of colorectal cancer. In this context, this perspective would serve as a platform for design of new medicinal agents by targeting cellular essential components which could accelerate anti-colorectal potential candidates.

Abstract
Colorectal cancer, which is considered one of the leading causes of mortality worldwide, develops through the formation of benign polyps on the inner colon or rectum wall. Truncations in adenomatous polyposis coli (APC) gene lead to the spread of the disease in the entire colon region when combined with the guanine nucleotide exchange factor (GEF) Asef. A series of peptidomimetic agents were previously discovered as protein-protein interaction inhibitors that can target the APC-Asef interface. Structure-based virtual screening (SBVS), using a set of docking methods combined with molecular dynamics simulations, was carried out to identify new small drug-like agents. After the initial screening process, compounds with diverse chemical scaffolds and direct interaction with Arg549 and other active site residues were chosen and subjected to induce fit. The amide functional group found in the ligand hit structures showed strong interactions with Arg549, leading to observable conformational changes that allow suitable positioning within the peptide binding site. Furthermore, the pH-specific MD simulations of the top hit 838 within the APC-Asef binding site depicted significant interactions required for biochemical recognition in changing microenvironment. Predicted inhibitory constant (Ki) values and binding free energies of hits further described the significance of the amide group over the other chemical scaffolds. This combination of in silico approaches provides key insights for colorectal drug discovery programs targeting the APC-Asef interaction.

Abstract
Oxadiazoles are an important class of heterocyclic compounds, having broad-spectrum activity.
They were also reported as anticancer, and antioxidant agents, hence it is of significant importance
to explore new oxadiazoles. A series of eleven (5-aryl-N-[4-(trifluoromethyl)phenyl]-1,3,4-
oxadiazol-2-amines (6a-k) was synthesized based on the structures of reported compounds, SU-101,
IMC38525, and FTAB. All these oxadiazoles were synthesized, characterized by spectral data, and further
tested against melanoma, leukemia, colon, lung, CNS, ovarian, renal, breast and prostate cancer
cell lines’ panels at a single dose of 10 μM drug concentrations. N-(4-(Trifluoromethyl)phenyl)-5-(3,4-
dimethoxyphenyl)-1,3,4-oxadiazol-2-amine (6h) showed significant anticancer activity, and the most
sensitive five cell lines were NCI-H522 (% GI = 53.24), K-562 (% GI = 47.22), MOLT-4 (% GI =
43.87), LOX-IMVI (% GI = 43.62), and HL-60(TB) (% GI = 40.30). The compound, 6h revealed better
%GIs than imatinib, against 36 cell lines, taking 54 cell lines in common. The maximum sensitivity
was recorded against cancer cell line CCRF-CEM (% GI = 68.89) by 2-(5-(4-(trifluoromethyl)
phenylamino)-1,3,4-oxadiazol-2-yl)phenol (6f). The antioxidant activity of 4-(5-(4-(trifluoromethyl)
phenylamino)-1,3,4-oxadiazol-2-yl)-2-methoxyphenol (6i) was promising with an IC50 of 15.14 μM. It
was observed that the oxadiazoles reported herein showed significant anticancer and antioxidant activities.

Abstract
A series of new 1,4-dihydroindeno[1,2-c]pyrazole tethered carbohydrazide hybrids (5a-u) were designed, synthesized and evaluated for their antimicrobial activity. Compounds 5d, 5g, 5j, 5k and 5q demonstrated significant activity against the entire panel of test pathogens. Further, compounds 5d and 5g exhibited significant anti-Candida activity. These potential hybrids (5d and 5g) also exhibited promising ergosterol biosynthesis inhibition against Candida albicans, which was further validated through molecular docking studies. Furthermore, compounds 5d and 5g caused intracellular ROS accumulation in C. albicans MTCC 3017 and were non-toxic to normal human lung cell line MRC5. In silico studies revealed that they demonstrated drug likeness and an appreciable pharmacokinetic profile. Overall, the findings demonstrate that 5d and 5g may be considered as promising leads for further development of new antifungal drugs.

Abstract
Dimethylarginine dimethylaminohydrolase1 (DDAH1) inhibitors are important therapeutics by virtue of their ability to control nitric oxide (NO) production by elevating asymmetric dimethylarginine (ADMA) levels. In a screening campaign, we identified that DD1E5 (3-amino-6- tert-butyl-N-(1,3-thiazol-2-yl)-4-(trifluoromethyl)thieno[2,3- b]pyridine-2- carboxamide) inhibits the DDAH1 activity both in vitro and in cultured cells. Mechanistic studies found that DD1E5 is a competitive inhibitor (dissociation constant ( Ki) of 2.05 ± 0.15 μM). Enzyme kinetic assays showed time and concentration dependent inhibition of DDAH1 with DD1E5, which shows tight binding with an inactivation rate constant of 0.2756 ± 0.015 M-1 S-1. Treatment of cancer cells with DDAH1 inhibitors shows inhibition of cell proliferation and a subsequent decrease in NO production with ADMA accumulation. DD1E5 reversed the elevated VEGF, c-Myc, HIF-1α, and iNOS levels induced by exogenous DDAH1 overexpression in PCa cells. Moreover, DD1E5 significantly increased intracellular levels of ADMA and reduced NO production, suggesting its therapeutic potential for cancers in which DDAH1 is upregulated. In in vitro assays, DD1E5 abrogated the secretion of angiogenic factors (bFGF and IL-8) into conditional media, indicating its antiangiogenic potential. DD1E5 inhibited in vivo growth of xenograft tumors derived from PCa cells with DDAH1 overexpression, by reducing tumor endothelial content represented with low CD31 expression. VEGF, HIF-1α, and iNOS expression were reversed in DD1E5 treated tumors compared to respective control tumors. In this work, integrating multiple approaches shows DD1E5 is a promising tool for the study of methylarginine-mediated NO control and a potential therapeutic lead compound against pathological conditions with elevated NO production such as cancers and other diseases.

Abstract
Inhibition of cyclin dependent kinase 4 (Cdk4) prevents cancer cells from entering the early G0/G1 phase of the cell division cycle whereas inhibiting tubulin polymerization blocks cancer cells' ability to undergo mitosis (M) late in the cell cycle. We had reported earlier that two non-planar and relatively non-toxic fascaplysin derivatives, an indole and a tryptoline, inhibit Cdk4 with IC50 values of 6.2 and 10 μM, respectively. Serendipitously, we had also found that they inhibited tubulin polymerization. The molecules were efficacious in mouse tumor models. We have now identified Cink4T in a 59-compound quinazolinone library, designed on the basis of ligand-based virtual screening, as a compound that inhibits Cdk4 and tubulin. Its IC50 value for Cdk4 inhibition is 0.47 μM and >50 μM for inhibition of Cdk1, Cdk2, Cdk6, Cdk9. Cink4T inhibits tubulin polymerization with an IC50 of 0.6 μM. Molecular modelling studies on Cink4T with Cdk4 and tubulin crystal structures lend support to these observations. Cancer cell cycle analyses confirm that Cink4T blocks cells at both G0/G1 and M phases as it should if it were to inhibit both Cdk4 and tubulin polymerization. Our results show, for the very first time, that virtual screening can be used to design novel inhibitors that can potently block two crucial phases of the cell division cycle.

Abstract
Background:
Cancer caused nearly 8.8 million deaths in 2015. Limited efficacy, selectivity,
drug resistance and toxicity are major complications associated with chemotherapy, potentiating
the discovery of anticancer agents.
Methods:
A new series of N-(7-hydroxy-4-methyl-2-oxoquinolin-1(2H)-yl)acetamide/benzamide
analogues (5a-j) was prepared from the precursor, 7-hydroxy-4-methyl-2H-chromen-2-one (3), as
anticancer agent. The structural assignment of quinolone analogues (5a-j) was based on spectroscopic
data analyses. The cytotoxicity was tested on breast cancer cell lines (MCF7 and MDA-MB-
231) by sulforhodamine B (SRB) assay and three dose-related parameters GI50, TGI, and LC50 were
calculated.
Results:
2-(2-chlorophenoxy)-N-(7-hydroxy-4-methyl-2-oxoquinolin-1(2H)-yl)acetamide (5a)
showed the most potent cytotoxicity against the MCF7 and MDA-MB-231 cancer cell lines with
GI50 of 18.7 and 48.1 µM respectively. The glide scores of the compounds, 5a-d were found to be
related to the cytotoxicity profile and the emodel scores for ligands, 5a-j were found to be related to
significant cytotoxicity.
Conclusion:
Compound 5a exhibited the most potent cytotoxicity and this report may provide some
predictions to design more potent novel quinolines as cytotoxic agents.

Abstract
BACKGROUND Chikungunya is a viral infection caused by Chikungunya virus (CHIKV), an arbovirus transmitted through mosquito (Aedes aegypti and Aedes albopictus) bite. The virus from sylvatic cycle in Africa mutated to new vector adaptation and became one of the major emerging and re-emerging viral infections in the past decade, affecting more than 40 countries. Efforts are being made by many researches to develop means to prevent and control the infection through vaccines and vector control strategy. On the other hand, search for novel chemotherapeutic agents for the treatment of infected patients is on. Approach of repurposed drug is one way of identifying an existing drug for the treatment of CHIKV infection. OBJECTIVE Review the history of CHIKV nsp2 protease inhibitors derived through structure-based computer-aided drug design along with phytochemicals identified as anti-CHIKV agents. METHODS A survey on CHIKV inhibitors reported till date has been carriedout. The data obtained were organized and discussed under natural substances and synthetic derivatives obtained as result of rational design. RESULTS The review provides a well organized content in chronological order that has highly significant information for medicinal chemist who wish to explore the area of Anti-CHIKV drug design and development. Natural compounds with different scaffolds provides an opportunity to explore Ligand based drug design (LBDD), while rational drug design approaches provides opportunity to explore the Structure based drug design. CONCLUSION From the presented mini-review, readers can understand that this area is less explored and has lots of potential in anti-CHIKVviral drug design & development. of reported literature inferred that, unlike other viral proteases, the nsP2 protease can be targeted for CHIKV viral inhibition. The HTVS process for the identification of anti-CHIK agents provided a few successive validated lead compounds against CHIKV infections.

Abstract
BACKGROUND The anti-mitotic activity of podophyllotoxin derivative targeting tubulin enzyme proved them as strong polymerization inhibitors. The introduction of heteroatom along with different heteroaryl systems in naturally obtained lignans created a latitude for design of bioactive components. A novel one-pot sequential propargylation/cycloaddition reaction strategy has been followed to synthesize triazolo-heterolignans. OBJECTIVE To screen anti-proliferative activity of novel heterolignans and to determine their mode of action. METHOD SRB assay, Cytotoxicity evaluation, PI uptake for analysis of cell cycle, caspase-3 activity, Western blot analysis and Immunofluorescence and molecular docking studies. RESULTS SRB assay of synthesised compounds were provided compound 3a and 5f to be highly active among the synthesized compounds. The Compound 3a showed cell cycle arrest at G2/M phase and 5f arrest the cells at G1 phase. Compound 5f displayed caspase 3 mediated apoptotic effect at lower levels. Compound 3a and 5f displayed microtubule disassembly inhibition same as paclitaxel and found to be occupying colchicine binding site of tubulin, both ligands were depicted π-cation interaction with Lys352 residue and triazole ring accommodated at the lactone binding site. CONCLUSION A novel one-pot sequential propargylation/cycloaddition reaction has been developed for the synthesis of triazolo-heterolignans. Compound 3a and 5f were displayed good cytotoxic activities and found to inhibit microtubule disassembly. The importance of triazole ring of heterolignans has been studied by molecular docking experiments and results were compared.

Abstract
Background:
1,3,4-Oxadiazole heterocycles possess a broad spectrum of biological activities. They
were reported as potent cytotoxic agents and tubulin inhibitors; hence it is of great interest to explore new
oxadiazoles as cytotoxic agents targeting tubulin polymerization.
Objective:
Two new series of oxadiazoles (5a-h and 12a-h) were synthesized, structurally related to the heterocyclic
linked aryl core of IMC-038525, NSC 776715, and NSC 776716, with further modification by incorporating
methylene linker.
Method:
The 2,5-disubstituted-1,3,4-oxadiazoles (5a-h and 12a-h) were synthesized by refluxing an equimolar
mixture of the intermediates [(4) and (8a-d)] and aromatic aldehydes in water-ethanol system using sodium
bisulphite catalyst. The cytotoxicity evaluation was carried out according to the National Cancer Institute (NCI
US) Protocol, while the tubulin polymerization assay kits from Cytoskeleton ™(bk011p) was used to perform an
in vitro tubulin polymerization assay.
Results:
2-(5-{[(4-Chlorophenyl)amino]methyl}-1,3,4-oxadiazol-2-yl)phenol (5f) and 2-[(2,4-dichlorophenoxy)
methyl]-5-(3,4-dimethoxyphenyl)-1,3,4-oxadiazole (12c) showed maximum cytotoxicity with the mean percent
growth inhibitions (GIs) of 71.56 and 72.68 respectively at 10 µM drug concentrations. Both the compounds (5f
and 12c) showed superior cytotoxicity than clinically prevalent anticancer drugs, Imatinib and Gefitinib in one
dose assay. The compound 12c showed promising results in five dose assay, with GI50 values varies between
1.61 and >100 µM. Furthermore, the compounds, 5f and 12c also inhibited the polymerization of tubulin with,
an IC50 of 2.8 and 2.2 µM, respectively.
Conclusion:
The oxadiazoles reported herein are tubulin inhibitors and cytotoxic agents. These findings will be
helpful in future drug design of more potent tubulin inhibitor cytotoxic agents.

Abstract
The present outbreak associated with Ebola disease in Western countries of the African continent which is believed to be one of the massive eruptions caused by the Ebola viral infections. In the present scenario ebola has been transmitted to the European and American regions through the travelers from wide spread countries like Guinea, Liberia, Sierra Leone and Nigeria. The viral disease is spreading through the contact in any form by the infected persons or patients and creating huge risks to the mortals. The symptoms related to ebola virus are often highly pathogenic; about 70-80% of death cases are reported due to critical hemorrhagic fever. Early in infection, ebola virus infects macrophages and endothelial cells. It mainly produces a Viral Protein 24 (eVP24) which prevents interferon-based signals which are important for destruction of viruses. How ebola virus manipulates the function of the immune system is still unclear. Due to lack of this knowledge, no approved treatment is available. In this review, we have tried to compile the epidemiology, pathogenesis and treatment of ebola virus infection. The promising ligands against ebola virus have been also discussed which will be helpful for researchers to design drugs for the treatment of ebola virus disease.

Abstract
Curcumin, a main component of Curcuma Longa Linn, is a plant polyphenol used as an immune-enhancer in the Indian system of traditional medicine. However, its underlying mechanism of immune-protection remains unknown. The present study is designed to delineate the role of curcumin in deltamethrin (DLM)-induced thymocyte apoptosis and altered immune functions. In silico studies revealed that curcumin has a strong binding affinity toward CD4 and CD8 receptors. DLM (25 µM) induces thymocytes apoptosis through oxidative stress and caspase-dependent pathways. Various concentrations of curcumin (1, 10 and 50 µg/ml), when added along with DLM, caused a concentration- and time-related amelioration in apoptogenic signaling pathways induced by DLM. Inhibition of DLM-induced reactive oxygen species production, replenishment of glutathione and suppression of caspase activities by curcumin may thus be responsible for the suppression of downstream cascade of events, i.e. apoptosis, phenotypic changes and altered cytokine release. Thus, this study clearly demonstrates that the mechanism of immunoprotection of curcumin in DLM-induced thymic apoptosis includes inhibition of oxidative stress and caspase-dependent pathways underlying apoptosis.

Abstract
Tuberculosis (TB), a dreadful disease is one of the most important health problems worldwide, and is responsible for approximately 1.3 million death tolls in 2012. DOTS is the currently used drug therapy in TB and the long term drug regimens and patients' poor compliance lead to emergence of multidrug resistant (MDR) and extensively drug resistant (XDR) TB, which invigorates the research efforts to address the urgent need for the quick diagnosis and for newer antitubercular agents and vaccines to completely eradicate TB. Today we have at least 20 new diagnostic test platforms, 14 TB vaccine candidates in clinical trials and over 35 candidates in preclinical development, and among the antitubercular agents under clinical investigation, 4 anti-TB agents are in Phase III (efficacy) trials and 7 anti-TB agents are in Phase II, early bactericidal activity and sputum culture conversion trials (rifapentine is in a Phase II and a Phase III trial), 5 anti-TB agents in preclinical development and 3 anti-TB agents in Good Laboratory Practice toxicity evaluation. Recently US FDA has approved TMC207 as a part of combination therapy to treat adults with MDR pulmonary TB in the absence of other alternatives. We provide here the concise review on the chemical entities currently in the clinical trials, the new vaccines in the developmental pipeline, and the new diagnostic test.
