Abstract
Serotonergic (5-hydroxytryptamine; 5-HT) receptors play critical roles in neurological and psychological disorders such as schizophrenia, anxiety, depression, and Alzheimer's diseases. Therefore, it is particularly important to develop novel radioligands or modify the existing ones to identify the serotonergic receptors involved in psychiatric disorders. Among the 16 subtypes of serotonergic systems, only technetium-99m based radiopharmaceuticals have been evaluated for serotonin-1A (5-HT1A), serotonin-2A (5-HT2A), 5-HT1A/7 heterodimers and serotonin receptor neurotransmitter (SERT). This review focuses on recent efforts in the design, synthesis and evaluation of 99mTc-radioligands used for single photon emission computerized tomography (SPECT) imaging of serotonergic (5-HT) receptors. Additionally, the discussion will cover aspects such as chemical structure, in vitro/vivo stability, affinity toward serotonin receptors, blood-brain barrier permeation (BBB), and biodistribution study.

Abstract
The design and development of novel efficient fluorescent chemical sensors for the selective detection of ions is currently of significant importance in supramolecular chemistry. Since zinc is a ubiquitous, indispensable and the second most abundant metal ion in the human body, developing chemosensors that can accurately discriminate between Zn2+ and Cd2+ ions has been a challenge due to their similar properties as they are in the same group of the periodic table. Therefore, a technique to trace and visualize free zinc ions is demanded. In this study, an innovative coumarin-based Schiff base (L) was synthesized and characterized by 1H NMR, 13C NMR and mass spectroscopy. A novel "Turn On" fluorescence chemosensor platform was developed for trace amounts of Zn2+ ions. The fluorescence Job's plot measurement was used to determine the complexation ratio between the probe and Zn2+ ion, which showed a maximum point indicating the formation of a ML2 adduct. Additionally, the geometrical parameters calculated using DFT and TD-DFT calculations were in close agreement with the experimentally observed values.

Abstract
BACKGROUND Antifungal resistance is the main health concern in the control of invasive fungal infections. This research was designed to further assess the antifungal activity of aryl-1,2,4-triazole-3-ylthio analogs of fluconazole (ATTAFs) against Candida albicans systemic candidiasis in the murine model. MATERIALS & METHODS The murine model of systemic candidiasis was designed via the inoculation of 1 × 106 CFU of Candida albicans. The treatment dosages of 3.5 and 35 mg/kg per day were selected for ATTAFs and fluconazole, respectively. The median survival time (MST) was assayed for 30 days post-infection. The quantitative and qualitative (via histopathology staining) fungal burden was also assessed. Furthermore, immunohistochemistry and biochemistry assays were performed to monitor anti-inflammatory activity using the Cyclooxygenase-2 (Cox-2) marker and changes in serum protein levels. RESULTS ATTAFs considerably improved the survival of the murine model (P < 0.003). Compared with fluconazole, the antifungal activity of ATTAFs and their MST showed no difference (P > 0.05). However, these compounds decreased the fungal burden in the kidneys, spleen, and liver. CONCLUSION Our research indicates that ATTAF-1 and ATTAF-2 are effective therapeutic agents due to their fungal clearing and increasing the MST in the murine model of systemic candidiasis. Although we concluded that these components are novel and promising candidates for the management of invasive candidiasis, further studies are warranted to correlate these findings with clinical outcomes.

Abstract
Health and convenience are two indispensable indicators of the society promotion. Nowadays, to improve community health levels, the comfort of patients and those in need of health services has received much attention. Providing Home Health Care (HHC) services is one of the critical issues of health care to improve the patient convenience. However, manual nurse planning which is still performed in many HHC institutes results in a waste of time, cost, and ultimately lower efficiency. In this research, a multi-objective mixed-integer model is presented for home health care planning so that in addition to focusing on the financial goals of the institution, other objectives that can help increase productivity and quality of services are highlighted. Therefore, four different objectives of the total cost, environmental emission, workload balance, and service quality are addressed. Taking into account medical staff with different service levels, and the preferences of patients in selecting a service level, as well as different vehicle types, are other aspects discussed in this model. The epsilon-constraint method is implemented in CPLEX to solve small-size instances. Moreover, a Multi-Objective Variable Neighborhood Search (MOVNS) composed of nine local neighborhood moves is developed to solve the practical-size instances. The results of the MOVNS are compared with the epsilon-constraint method, and the strengths and weaknesses of the proposed algorithm are demonstrated by a comprehensive sensitivity analysis. To show the applicability of the algorithm, a real example is designed based on a case study, and the results of the algorithm over real data are evaluated.

Abstract
A novel series of triazole alcohol antifungals bearing a 5-benzoylbenzimidazol-2-ylthio side chain have been designed and synthesized as hybrids of fluconazole (a typical triazole antifungal) and mebendazole (an anthelmintic agent with antifungal activity). The title compounds were synthesized via the reaction of an appropriate oxirane and desired 2-mercaptobenzimidazole. Although there was possibility for formation of different N-substituted or S-substituted products, the structures of final compounds were assigned as thioether congeners by using 13C NMR spectroscopy. The SAR analysis of the primary lead compounds (series A) was conducted by simplifying the 5-benzoylbenzimidazol-2-ylthio residue to the benzimidazol-2-ylthio (series B) or benzothiazol-2-ylthio side chain (series C), and modification of halogen substituent on the phenethyl-triazole scaffold. In general, series A (compounds 4a-e) containing 5-benzoylbenzimidazole scaffold showed better antifungal activity against Candida spp. and Cryptococcus neoformans than related benzimidazole and benzothiazole derivatives. The better results were obtained with the 4-chloro derivative 4b displaying MICs <0.063-1 μg/mL. Although, removing benzoyl group from compound 4b had negative effect on the activity, optimization of phenethyl-triazole scaffold by desired halogen substituent resulted in compound 5c being as potent as 4b. In vitro and in silico ADMET evaluations of the most promising compounds 4b and 5c indicated that the selected compounds have desirable ADMET properties in comparison to standard drug fluconazole. Docking simulation study demonstrated that the benzimidazol-2-ylthio moiety is responsible for the potent antifungal activity of these compounds.

Abstract
Levofloxacin, the optical S-(-) isomer of ofloxacin, is a broad-spectrum antibacterial agent widely used to control various infections caused by Gram-positive and Gram-negative bacteria. While the COOH group is necessary for antibacterial activity, its modification can offer anticancer activity to the fluoroquinolone framework. Therefore, several levofloxacin carboxamides 11a-j and 12 containing 5-substituted-1,3,4-thiadiazole residue were synthesized and screened in vitro for their anticancer activity. The in vitro MTT viability assay revealed that the most compounds had significant activity against cancer cells MCF-7, A549, and SKOV3. In particular, the 3-chloro- and 4-fluoro- benzyl derivatives (11b and 11h), with IC50 values of 1.69-4.76 μM were as potent as or better than doxorubicin. It should be noted that the mother quinolone levofloxacin showed no activity on the tested cancer cell lines. The SAR analysis demonstrated that the 3-chloro or 4-fluoro substituent on the S-benzyl moiety had positive effect on the activity. Further in vitro evaluations of the most promising compounds 11b and 11h by flow cytometric analysis and comet test revealed the ability of compounds in the induction of apoptosis and blockage of the cell proliferation at the G1-phase by nuclear fragmentation and DNA degradation in cancer cells. The obtained results demonstrated that the alteration of 6-COOH functional group in the levofloxacin structure and conjugation with a proper heterocyclic pharmacophore is a good strategy to obtain new anticancer agents.

Abstract
A series of novel 3-substituted-4-hydroxycoumarins 7 and 8 containing (5-aryl-1,3,4-oxadiazol-2-yl)thio or (4-amino-5-aryl-4H-1,2,4-triazol-3-yl)thio moieties have been synthesized and evaluated as anticancer agents. The in vitro MTT assay of compounds against hepatocellular carcinoma (HepG2), breast cancer (MCF7) cells, and a human colorectal adenocarcinoma cell line with epithelial morphology (HT29) indicated that the HepG2 cells had more susceptibility to the tested compounds. Indeed, all compounds (with the exception of 7b, 7c, 7g, and 8g) were more potent than the standard drug doxorubicin against HepG2 cells (IC50 values=1.65-3.83 μM). Although, the better result was obtained with the oxadiazole analog 7h against HepG2 (IC50 =1.65 μM), the N-amino-triazole derivatives 8c, 8e, 8f and, 8h with IC50 values of 1.78-6.34 μM showed potent activity against all tested cell lines. The good drug-like properties and in vitro potency and selectivity of 4-hydroxycoumarins 8 make them as good leads for the development of new anticancer agents.

Abstract
Poster session 1, September 21, 2022, 12:30 PM - 1:30 PM Objectives Candida albicans is the most common cause of nosocomial bloodstream infections and are associated with substantial morbidity and mortality in immunocompromised individuals. However, limited therapeutic approaches against invasive candidiasis are available. The rise in antifungal resistance highlights the urgent need to develop new therapeutic options and novel treatment strategies to combat later infections. A novel compound Aryl-1, 2, 4-triazol-3- ylthio, fluconazole alcohol-derived analogs (ATTAFs), has newly developed with potent in vitro activity against Candida species, including fluconazole-resistant isolates. The objective of this study was to further evaluate the in vivo effectiveness in a murine model of invasive candidiasis due to C. albicans. Methods Treatment with ATTAF-1 and ATTAF-2 significantly increased the survival of infected mice compared to the control group (5% DMSO plus inoculum). Results The antifungal action of ATTAF-1 and ATTAF-2 and their median survival time provided no evidence of a difference versus fluconazole. Although there was an obvious fungal load (mean log CFU/g of tissue) decrease by ATTAF-1 and ATTAF-2 in the kidney, spleen, and liver of the treated mice in comparison with the control group and not similar to each other in regard of the dose, fluconazole showed a significant decrease in the number of fungal loads, similar to the group treated with ATTAF-1 and ATTAF-2. Nevertheless, the results of this study indicate that the use of ATTAF-1 and ATTAF-2 as a therapeutic agent can exert significant in vitro and in vivo antifungal effects against C. albicans, increasing animal survival and significantly decreasing fungal loads. Conclusion Although we have identified two new compounds, ATTAF-1 and ATTAF-2, as novel promising Candidates for the treatment of Candida infection, more studies of ATTAF-1 and ATTAF-2 activity and their action mechanisms in animal models are warranted to enhance our understanding and establish their efficacy.

Abstract
Toxoplasmosis is a disease with a worldwide prevalence that is caused by Toxoplasma gondii. Pyrimethamine and sulfadiazine are two pharmacological agents commonly used to treat of this infection. However, they are accompanied by some side effects. Therefore, the identifying of new drugs with low toxocytosis seems to be a matter of vital importance. Quinolones are DNA replication inhibitors, exerting inhibitory effects against many pathogens, including bacteria, mycoplasma, and protozoa. Given the importance of quinolones and their efficacy, the present in vitro study was conducted to investigate the antiparasitic activities of new quinolones (NFQ-2, NFQ-5, and NFQ-6) containing nitrofuran moiety against T. gondii. To this end, Vero cells were incubated with various concentrations of new quinolones and pyrimethamine (positive control) to determine their viability. Subsequently, they were infected with T. gondii (RH strain) and then subjected to drug treatment. The obtained IC50 values were 3.60, 4.84, 5.59, 3.44 and 2.75 μg/mL for NFQ-2, NFQ-5, NFQ-6, ciprofloxacin and pyrimethamine, respectively. The CC50 values for the NFQ-2, NFQ-5, and NFQ-6 were 25.20, 29.89, and 28.43 μg/mL, indicating the selectivity indexes more than 5 for these compounds. The anti-Toxoplasma efficiency was determined by evaluating infection index, number and size of plaques, and T. gondii intracellular proliferation. As the results indicated, the administration of new quinolone derivatives resulted in the reduction of intracellular proliferation, infection index, and the number and size of plaques in comparison to uninfected treated cells (P < 0.05). The results were indicative of a considerable synergetic effect when each of the derivatives was used in combination with pyrimethamine, compared to when used alone. Based on our results, the nitrofuran-derived quinolones can be considered as new leads for the design of new anti-Toxoplasma agents.

Abstract
The causative agent of coronavirus disease‐2019 (COVID‐19), severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), enters the host cells via an angiotensin‐converting enzyme 2 (ACE2)‐mediated endocytosis‐dependent manner. Because ACE2 is highly expressed in the heart, SARS‐CoV‐2 can severely infect heart tissue and arteries, causing acute and chronic damage to the cardiovascular system. Therefore, special attention should be paid to finding appropriate agents to protect this vital system during COVID‐19 treatment. Papaverine is a unique vasodilator alkaloid that is clinically used in the treatment of vasospasm. Interestingly, this compound has potent and direct effects on a wide range of viruses, and could also prevent viral exploitation mechanisms of the host cell facilities by inhibiting some cellular signaling pathways such as p38 MAPK. This pathway was recently introduced as a promising target for the treatment of COVID‐19. Papaverine also has anti‐inflammatory effects which is useful in combating the hyper‐inflammatory phase of the COVID‐19. Unlike some medications that have severe dosage‐restrictions in the treatment of COVID‐19 due to cardiac side effects, papaverine is recommended for use in many heart disorders. The ability of papaverine to treat COVID‐19 has become more promising when the results of some extensive screenings showed the strong ability of this compound to inhibit the cytopathic effects of SARS‐CoV‐2 with EC50 of 1.1 μM. Having several therapeutic effects along with desired safety profile raises this hypothesis that papaverine could be a promising compound for the suppression of SARS‐CoV‐2 and prevention of ischemia/vasoconstriction‐related complications in COVID‐19 disease, especially in patients with underlying cardiovascular diseases (CVDs).

Abstract
Kojic acid (KA) is a hydroxypyranone natural metabolite mainly known as tyrosinase inhibitor. Currently, this compound is used as a whitening agent in cosmetics and as an anti-browning agent in food industry. Given the easy-manipulation in different positions of the KA molecule, many investigations have been carried out to find new tyrosinase inhibitors derived from KA. Beside anti-tyrosinase activity, many KA-based compounds have been designed for targeting other enzymes including human neutrophil elastase, catechol-O-methyltransferase, matrix metalloproteinases, monoamine oxidase, human lactate dehydrogenase, endonucleases, D-amino acid oxidase, and receptors such as histamine H3 and apelin (APJ) receptors. This review could help biochemists and medicinal chemists in designing diverse KA-derived enzyme inhibitors.

Abstract
Quinazolines are considered as a promising class of bioactive heterocyclic compounds with broad properties. Particularly, the quinazoline scaffold has an impressive role in the design and synthesis of new CNS-active drugs. The drug-like properties and pharmacological characteristics of quinazoline could lead to different drugs with various targets. Among CNS disorders, Alzheimer's disease (AD) is a progressive neurodegenerative disorder with memory loss, cognitive decline and language dysfunction. AD is a complex and multifactorial disease therefore, the need for finding multi-target drugs against this devastative disease is urgent. A literature survey revealed that quinazoline derivatives have diverse therapeutic potential for AD as modulators/inhibitors of β-amyloid, tau protein, cholinesterases, monoamine oxidases, and phosphodiesterases as well as other protective effects. Thus, we describe here the most relevant and recent studies about anti-AD agents with quinazoline structure which can further aid the development and discovery of new anti-AD agents.

Abstract
In continuation of our research to find strong and safe anticonvulsant agents, a number of (arylalkyl)azoles (AAAs) containing naphthylthiazole and naphthyloxazole scaffolds were designed and synthesized. The in vivo anticonvulsant evaluations in BALB/c mice revealed that some of them had significant anticonvulsant activity in both maximal electroshock (MES) and pentylenetetrazole (PTZ) models of epilepsy. The best profile of activity was observed with compounds containing imidazole and triazole rings (C1, C6, G1, and G6). In particular, imidazolylmethyl-thiazole C1 with median effective dose (ED50)= 7.9 mg/kg in the MES test, ED50= 27.9 mg/kg in PTZ test, and without any sign of neurotoxicity (in the rotarod test, 100 mg/kg) was the most promising compound. The patch-clamp recording was performed to study the mechanism of action of the representative compound C1 on hippocampal dentate gyrus (DG) cells. The results did not confirm any modulatory effect of C1 on the voltage-gated ion channels (VGICs) or GABAA agonism, but suggested a significant reduction of excitatory postsynaptic currents (EPSCs) frequency on hippocampal DG neurons. Sub-acute toxicity studies revealed that administration of the most active compounds (C1, C6, G1, and G6) at 100 mg/kg bw/day for two weeks did not result in any mortality or significant toxicity as evaluated by assessment of biochemical markers such as lipid peroxidation, intracellular glutathione, total antioxidant capacity, histopathological changes, and mitochondrial functions. Other pharmacological aspects of compounds including mechanistic and ADME properties were investigated computationally and/or experimentally. Molecular docking on the NMDA and AMPA targets suggested that the introduction of the heterocyclic ring in the middle of AAAs significantly affects the affinity of the compounds. The obtained results totally demonstrated that the prototype compound C1 can be considered as a new lead for the development of anticonvulsant agents.

Abstract
Helicobacter pylori is one of the main causal risk factor in the generation of chronic gastritis, gastroduodenal ulcers and gastric carcinoma. Thus, the eradication of H. pylori infection is an important way for preventing and managing the gastric diseases. Multiple-therapy with several antibacterial agents is used for the eradication of H. pylori infections; however the increase of resistance to H. pylori strains has resulted in unsatisfactory eradication and unsuccessful treatment. Furthermore, the combination therapy with high dosing leads to the disruption of intestinal microbial flora and undesired side effects. Therefore, the search for new therapeutic agents with high selectivity against H. pylori is a field of current interest. In recent years, diverse compounds originating from natural sources or synthetic drug design programs were evaluated and tried to optimize for applying against H. pylori. In this review, we have described various classes of anti-H. pylori compounds, their structure-activity relationship studies, and mechanism of actions, which could be useful for the development of new drugs for the treatment of H. pylori infections.

Abstract
With a poor prognosis, glioblastoma multiforme is the most aggressive tumor of the central nervous system in humans. The aim of this study was to develop novel tracers for the tumor targeting and imaging of overexpressed serotonin-7 receptors (5-HT7Rs) in U-87 MG glioma xenografted nude mice. Two phenylpiperazine derivatives named as PHH and MPHH were designed, and the corresponding radiotracers 99mTc-PHH and 99mTc-MPHH were synthesized in high radiochemical purity (>95%). 99mTc-MPHH showed a higher affinity to 5-HT7Rs on U-87 MG cells compared to 99mTc-PHH. In biodistribution studies, the radiocomplexes showed good brain uptake at 15 min combined with good radioactivity retention in the brain for 240 min. Regional rabbit brain studies indicated a higher radioactivity concentration in the hippocampus and diencephalon than in the cerebellum. Compared to 99mTc-MPHH, the 99mTc-PHH exhibited a significantly increased tumor uptake at 15 and 60 min, but the rapid blood clearance of 99mTc-MPHH led to enhanced tumor-to-muscle ratios at 240 min. A significant reduction in tumor uptake 60 min after an injection of pimozide (5-HT7 receptor antagonist) confirms the tumor uptake was receptor-mediated specifically. The tumor-to-contralateral muscle tissue ratio of 99mTc-PHH and 99mTc-MPHH in nude mice with U-87 MG xenograft was measured (5.25 and 4.65) at 60 min as well as (6.25 and 6.76) at 240 min, respectively.

Abstract
The quinolone-3-carboxylic acid scaffold is essential structure for antibacterial activity of fluoroquinolones such as ciprofloxacin. Modification of 3-carboxylic functionality in this structure can be used for switching its activity from antibacterial to anticancer. Accordingly, a series of C-3 modified ciprofloxacin derivatives containing N-(5-(benzylthio)-1,3,4-thiadiazol-2-yl)-carboxamide moiety was synthesized as novel anticancer agents. Most of compounds showed significant activity against MCF-7, A549 and SKOV-3 cancer cells in the MTT assay. In particular, compounds 13a-e and 13g were found to be as potent as standard drug doxorubicin against MCF-7 cell line (IC50s = 3.26-3.90 µM). Furthermore, the 4-fluorobenzyl derivatives 13h and 14b with IC50 values of 3.58 and 2.79 µM exhibited the highest activity against SKOV-3 and A549 cells, being as potent as doxorubicin. Two promising compounds 13e and 13g were further tested for their apoptosis inducing activity and cell cycle arrest. Both compounds could significantly induce apoptosis in MCF-7 cells, while compound 13e was more potent apoptosis inducer resulting in an 18-fold increase in the proportion of apoptotic cells at the IC50 concentration in MCF-7 cells. The cell cycle analysis revealed that compounds 13e and 13g could increase cell portions in the sub-G1 phase, inducing oligonucleosomal DNA fragmentation and apoptosis confirmed by comet assay.

Abstract
The data have been obtained for tautomers and enantiomers of ATTAF-1 and ATTAF-2 that were developed based on antifungal standard drugs with triazole scaffold. These compounds were docked into the human and fungal lanosterol-14α-demethylase. In order to validate the data, 8 standard triazole antifungal drugs (Fluconazole, Itraconazole, Posaconazole, Ravuconazole, Albaconazole, Voriconazole, Isavuconazole and Efinaconazole) were also docked into the human and fungal lanosterol-14α-demethylase. The binding conformations of these molecules and their interactions with lanosterol-14α-demethylase may inform the development of further small molecule lanosterol-14α-demethylase inhibitors with significant selectivity toward this enzyme. The analysis has done on the basis of type of interactions (bond type and distance). The length of the Fe-N coordination bond for (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 complexes is obtained 6.36 and 4.19 Å, respectively and about 2 Å in the other tautomer and enantiomer complexes, reflecting the lower basicity of the N-4 atom in the 1,2,4-triazole ring of (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 in comparison with the N-4 atom in the 1,2,4-triazole ring in other tautomers and enantiomers and supporting higher selectivity of (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2 towards the target CYP51 enzymes vs. human. Interestingly, we have investigated unfavorable interactions (donor-donor) with TRP239 and MET378 for (R)-N2-ATTAF-1 and (S)-N1-ATTAF-2, respectively. These unfavorable interactions also have been seen in case of posaconazole and isavuconazole. The data presented in this article are related to the research paper entitled "In silico prediction of ATTAF-1 and ATTAF-2 selectivity towards human/fungal lanosterol 14α-demethylase using molecular dynamic simulation and docking approaches".

Abstract
As part of our effort to develop potential tyrosinase inhibitors, we have conjugated the well-known tyrosinase inhibitor kojic acid (KA) with several phenolic natural products such as umbelliferone, sesamol, thymol, carvacrol, eugenol, isoeugenol, vanillin, isovanillin, and apocynin that some reports have shown their activity on tyrosinase enzyme. The designed compounds were synthesized using click reaction and 1,2,3-triazole formation. All compound showed potent anti-tyrosinase activity significantly higher than KA. The best activities were observed with apocynin and 4-coumarinol analogs (10c and 16c) displaying IC50 values of 0.03 and 0.02 μM, respectively. The potency of 16c was >460-times more than that of KA. Cell-based assays against B16F10 and HFF cells revealed that the representative compounds can efficiently suppress the melanogenesis without significant toxicity on cells.

Abstract
Background:
Chromene and anilinopyrimidine heterocyclics are attractive anticancer
compounds that have inspired many researchers to design novel derivatives bearing improved anticancer
activity.
Methods:
A series of pyrimidine-fused benzo[f]chromene derivatives 6a-x were synthesized as
anticancer hybrids of 1H-benzo[f]chromenes and anilinopyrimidines. The inhibitory activity of the
synthesized compounds 6a-x against cell viability of human chronic myelogenous leukemia
(K562), human acute lymphoblastic leukemia (MOLT-4) and human breast adenocarcinoma
(MCF-7) cell lines was evaluated using MTT assay. The interaction of the most promising compound
with calf-thymus DNA was also studied using spectrometric titrations and Circular Dichroism
(CD) spectroscopy.
Results:
Most compounds showed promising activity against tested cell lines. Among them, 2,4-
dimethoxyanilino derivative 6g exhibited the best profile of activity against tested cell lines
(IC50s = 1.6-6.1 μM) with no toxicity against NIH3T3 normal cell (IC50 >200 μM). The spectrometric
studies exhibited that compound 6g binds to DNA strongly and may change DNA conformation
significantly, presumably via a groove binding mechanism.
Conclusion:
The results of this study suggest that the prototype compound 6g can be considered as
a novel lead compound for the design and discovery of novel anticancer agents.

Abstract
Several flexible and rigid analogs of 4H-1,2,4-triazoles (compounds 8a-g and 9a-g) bearing trimethoxyphenyl pharmacophoric unit, were designed and synthesized as potential anticancer agents. The in vitro cytotoxic assay indicated that both flexible and rigid analogs (8 and 9, respectively) can potentially inhibit the growth of cancerous cells (A549, MCF7, and SKOV3), with IC50 values less than 5.0 µM. Furthermore, compounds 10a-l as regional isomers of compounds 9 exhibited remarkable cytotoxic activity with IC50 values ranging from 0.30 to 5.0 µM. The rigid analogs 9a, 10h and 10k were significantly more potent than etoposide against MCF7, SKOV3 and A549 cells, respectively. These compounds showed high selectivity towards cancer cells over normal cells, as they had no significant cytotoxicity against L929 cells. In addition, the representative compounds 9a and 10h could inhibit the tubulin polymerization at micro-molar levels. By determining changes in the colchicine-tubulin fluorescence, it was suggested that compound 10h could bind to the tubulin at the colchicine pocket. The molecular docking study further confirmed the inhibitory activity of promising compounds 9a, 10h and 10k on tubulin polymerization through binding to the colchicine-binding site.

Abstract
Background:
Alzheimer’s disease (AD) is an age-related progressive neurodegenerative disease.
Its prominent hallmarks are extracellular deposition of β-amyloids (amyloid plaques), intracellular
neurofibrillary tangles (NTFs), neurodegeneration and finally loss of cognitive function. Hence, AD diagnosis
in the early stage and monitoring of the disease are of great importance.
Methods:
In this review article, we have reviewed recent efforts for design, synthesis and evaluation of
99mTc labeled small molecule for AD imaging purposes.
Results:
These small molecules include derivatives of Congo red, benzothiazole, benzofuran, benzoxazole,
naphthalene, biphenyl, chalcone, flavone, aurone, stilbene, curcumin, dibenzylideneacetone,
quinoxaline, etc. The different aspects of 99mTc-labeled small molecules including chemical structure,
their affinity toward amyloid plaques, BBB permeation and in vivo/vitro stability will be discussed.
Conclusion:
The findings of this review confirm the importance of 99mTc-labeled small molecules for AD
imaging. Future studies based on the pharmacophore of these designed compounds are needed for improvement
of these molecules for clinical application.

Abstract
A number of 1H-1,2,4-triazole alcohols containing N-(halobenzyl)piperazine carbodithioate moiety have been designed and synthesized as potent antifungal agents. In vitro bioassays against different Candida species including C. albicans, C. glabrata, C. parapsilosis, C. krusei, and C. tropicalis revealed that the N-(4-chlorobenzyl) derivative (6b) with MIC values of 0.063-0.5 µg/mL had the best profile of activity, being 4-32 times more potent than fluconazole. Docking simulation studies confirmed the better fitting of compound 6b in the active site of lanosterol 14α-demethylase (CYP51) enzyme, the main target of azole antifungals. Particularly, the potential of compound 6b against fluconazole-resistant isolates along with its minimal toxicity against human erythrocytes and HepG2 cells make this prototype compound as a good lead for discovery of potent and safe antifungal agents.

Abstract
As current toxoplasmosis chemotherapies have many side effects along with toxicity on patients, we examined the anti-Toxoplasma effect of a biologically important natural antibiotic, kojic acid, in vitro and in vivo. Vero cells were incubated with different concentrations of kojic acid or pyrimethamine (positive control), and the cellular viability was determined. Next, Vero cells were infected with T. gondii (RH strain) and treated with drugs. Then, we calculated the infection index, T. gondii intracellular proliferation and the number and measure of plaque. Moreover, the effect of kojic acid on survival times, serum levels of IFN-γ and TNF-α and histopathological changes in the liver and spleen of Balb/c mice infected with T. gondii were determined. Kojic acid reduced the infection index, intracellular proliferation, the number and measure of plaque in vitro when compared to untreated infected cells. Kojic acid (100 mg/kg/day) also showed a better survival rate than infected untreated control mice (P < 0.05). IFN-γ and TNF-α secretions were significantly increased by kojic acid treatment in comparison to untreated groups (P < 0.05). In addition, its inhibitory effects on inflammatory alterations, apoptosis, and necrosis have been shown in sections of liver and spleen. We conclude that kojic acid exhibit potent anti-Toxoplasma activity with direct and indirect effects on the parasite, although further studies are needed before consideration of clinical trials.

Abstract
Previously, we have described a series of azole antifungals namely 3-(1,2,4-triazol-1-yl)flavanones (TFs) containing an N-(phenethyl)azole framework required for sterol 14α-demethylase (CYP51) inhibitory activity. Similar mechanism of action of azoles in fungi and protozoan parasites prompted us to investigate the potential effects of TFs against promastigote and amastigote forms of Leishmania major (L. major), as well as their toxicity against macrophages, apoptosis induction and in silico interactions with the target enzyme. All compounds showed more potent anti-parasitic activity against L. major in comparison with reference azole drug fluconazole and standard antileishmanial agent glucantime. Among the tested compounds, the 4-chloro derivative (TF-2) was found to be the most potent one, being about 13 times more potent than fluconazole against promastigotes. TF-2 decreased both mean infection rate of macrophages (MIR) and mean number of amastigotes per macrophages (MNAPM), significantly more than fluconazole (P < .001). Furthermore, the cytotoxicity assay against J774.A.1 macrophages revealed that this compound displays high selectivity against amastigotes over macrophages (SI = 30.21). The in silico study showed that TF-2 can properly accommodated in the active site of parasitic CYP51 and coordinated to the heme. The SAR analysis showed that the introduction of 4-chloro on 2-phenyl moiety results in the best profile of activity and selectivity. Accordingly, the compound TF-2 prototype can be considered as promising candidate for development of new antileishmanial agents.

Abstract
A novel series of benzylpyridinium-based benzoheterocycles (benzimidazole, benzoxazole or benzothiazole) were designed as potent acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. The title compounds 4a-q were conveniently synthesized via condensation reaction of 1,2-phenylenediamine, 2-aminophenol or 2-aminothiophenol with pyridin-4-carbalehyde, followed by N-benzylation using various benzyl halides. The results of in vitro biological assays revealed that most of them, especially 4c and 4g, had potent anticholinesterase activity comparable or more potent than reference drug, donepezil. The kinetic study demonstrated that the representative compound 4c inhibits AChE in competitive manner. According to the ligand-enzyme docking simulation, compound 4c occupied the active site at the vicinity of catalytic triad. The compounds 4c and 4g were found to be inhibitors of Aβ self-aggregation as well as AChE-induced Aβ aggregation. Meanwhile, these compounds could significantly protect PC12 cells against H2O2-induced injury and showed no toxicity against HepG2 cells. As multi-targeted structures, compounds 4c and 4g could be considered as promising candidate for further lead developments to treat Alzheimer's disease.

Abstract
A series of kojic acid-derived compounds 6a-p bearing aryloxymethyl-1H-1,2,3-triazol-1-yl moiety were designed by modifying primary alcoholic group of kojic acid as tyrosinase inhibitors. The target compounds 6a-p were synthesized via click reaction. All compounds showed very potent anti-tyrosinase activity (IC50s = 0.06-6.80 µM), being superior to reference drug, kojic acid. In particular, the naphthyloxy analogs 6o and 6p were found to be 31-155 times more potent than kojic acid. The metal-binding study of selected compound 6o revealed that the prototype compound possesses metal-chelating ability, particularly with Cu2+ ions. The promising compounds 6o and 6p had acceptable safety profile as demonstrated by cytotoxicity assay against melanoma (B16) cell line and Human Foreskin Fibroblast (HFF) cells.

Abstract
AIM AND BACKGROUND Azoles as antifungal drugs have been used to treat leishmaniasis for many years. Several evidences suggesting that the primary target of azoles is the heme protein, which co-catalyzes cytochrome P-450-dependent 14α-demethylation of lanosterol. Little is known about the structural changes caused by azoles with atomic force microscopy (AFM) or scanning electron microscopy (SEM). In the current work, several patented antileishmanial agents reviewed (US8809555) (US 0269803 A1) (TW201802093 A). The present study aimed to determine ultrastructural damage in Leishmania major (L.major) induced by the newly synthesized azole. METHODS In this study, we investigated the morphological alterations of the parasite treated with our new synthesized azole namely trans-2-(4-chlorophenyl)-2,3-dihydro-3-(1Himidazol- 1-yl)-4H-1-benzopyran-4-one (IF-2) against L.major promastigotes stage using two high-resolution microscopic techniques: atomic force microscopy and scanning electron microscopy. RESULTS The results showed remarkable topographical and morphological alterations in the cell membrane at promastigote stage of L. major treated with the potent investigated azole (IF-2) ( IC50 values ≤8.9 µg/mL). Both techniques revealed membrane damage and also losing the flagellum in the observed cells. CONCLUSION Our results strongly confirm the Leishmania cell wall as a potent target for the new synthesized azole (IF-2). Accordingly, focus on membrane integrity and glycoconjugates of Leishmania parasite to design new therapeutic agents is recommended.

Abstract
OBJECTIVES Pentavalent antimonials have been used for the treatment of leishmaniasis for over 70 years, however they are limited by their toxicity. Unfortunately, the efficacy of first-line drugs for the treatment of leishmaniasis has decreased and resistance is noticeable. Luliconazole is a new azole with unique effects on fungi that has not yet been tested on Leishmania parasites. METHODS In this study, the cytotoxicity and antileishmanial activity of luliconazole were evaluated in vitro against promastigotes and intracellular amastigotes of Leishmania major. The docking simulation with the target enzyme, sterol 14α-demethylase (CYP51) was performed using AutoDock 4.2 program. RESULTS The IC50 (concentration of test compound required for 50% inhibition) against promastigotes revealed that luliconazole (IC50=0.19μM) has greater potency than ketoconazole (KET), meglumine antimoniate (MA) and amphotericin B (AmB) (IC50 values of 135, 538 and 2.52μM, respectively). Against the amastigote stage, luliconazole at a concentration of 0.07μM decreased the mean infection rate and the mean number of amastigotes per macrophage more effectively than MA (P<0.004) and KET (P<0.043), but there was no difference compared with AmB (P>0.05). A docking study of luliconazole with the cytochrome P450 enzyme sterol 14α-demethylase (CYP51) revealed that this azole drug can properly interact with the target enzyme in Leishmania mainly via coordination with heme and multiple hydrophobic interactions. CONCLUSION These results show the potent activity of luliconazole at extremely low concentrations against L. major. It may therefore be considered as a new candidate for treatment of leishmaniasis in the near future.

Abstract
Cutaneous leishmaniasis is a neglected tropical disease and a major public health in the most countries. Leishmania major is the most common cause of cutaneous leishmaniasis. In the Leishmania parasites, sterol 14α-demethylase (CYP51), which is involved in the biosynthesis of sterols, has been identified as an attractive target for development of new therapeutic agents. In this study, the sequence and structure of CYP51 in a laboratory strain (MRHO/IR/75/ER) of L. major were determined and compared to the wild-type strain. The results showed 19 mutations including seven non-synonymous and 12 synonymous ones in the CYP51 sequence of strain MRHO/IR/75/ER. Importantly, an arginine to lysine substitution at position of 474 resulted in destabilization of CYP51 (ΔΔG = 1.17 kcal/mol) in the laboratory strain; however, when the overall effects of all substitutions were evaluated by 100 ns molecular dynamics simulation, the final structure did not show any significant changes (p-value < 0.05) in stability parameter of the strain MRHO/IR/75/ER compared to the wild-type protein. The energy level for the CYP51 of wild-type and MRHO/IR/75/ER strain were −40,027.1 and −39,706.48 Kcal/mol respectively. The overall Root-mean-square deviation (RMSD) deviation between two proteins was less than 1 Å throughout the simulation and Root-mean-square fluctuation (RMSF) plot also showed no substantial differences between amino acids fluctuation of the both protein. The results also showed that, these mutations were located on the protein periphery that neither interferes with protein folding nor with substrate/inhibitor binding. Therefore, L. major strain MRHO/IR/75/ER is suggested as a suitable laboratory model for studying biological role of CYP51 and inhibitory effects of sterol 14α-demethylase inhibitors.

Abstract
A series of 4-amino-5-cinnamoylthiazoles 3a-p were designed and synthesized as chalcone-like anticancer agents. The synthesized derivatives 3a-p were evaluated for their in vitro antiproliferative activities against three different human cancer cell lines including MCF-7, HepG2 and SW480. Most of compounds could significantly prevent proliferation of tested cell lines. In particular, the pyrrolidine derivative 3e namely (E)-1-(4-amino-2-(pyrrolidin-1-yl)thiazol-5-yl)-3-(2,4-dichlorophenyl)prop-2-en-1-one showed promising activity, especially against HepG2 cells (IC50 = 10.6 μg/ml). Flow cytometric analyses revealed that the prototype compound 3e can prevent the proliferation of HepG2 cells by blockade of the cell cycle at the G2 phase and induction of apoptosis.
