Abstract In this paper, a series of novel 5-fluorouracil-dithiocarbamate conjugates were designed, synthesized and evaluated in vitro . The results of cytotoxicity assays illuminated that these conjugates had anti-tumor activity against B16, Hela and U87MG, and compound P3 exhibited excellent growth inhibition against U87MG cells. Interestingly, the cytotoxicity of these conjugates was significantly increased when combined with copper ions. Meanwhile, colony-formation assays, transwell migration assays, cell apoptosis assays and cell cycle distribution assays were performed to explore the anti-tumor mechanism of conjugates. Compound P3 and P4 exhibited good biological activity in above four experiments when combined with copper ions. Especially, P3 displayed better bioactivity compared to the other three compounds. These results indicated that conjugates might be metabolized in the cells to produce dithiocarbamates, then metabolites formed complexes with copper ions, generating anti-tumor effects. Furthermore, conjugates and their metabolized dithiocarbamate derivatives were investigated by molecular docking, the results exhibited that P3 had the strongest interaction with the proteins 6CCY and 5T92, which was consistent with the obtained results of cell experiments. Compound P3 might be a potential lead-compound for the treatment of breast cancer and glioma. Further research in vivo about these compounds would be performed in our following work.

Background: Bedaquiline is a novel anti-tuberculosis drug that inhibits Mycobacterial ATP synthase. However, studies have found that bedaquiline has serious side effects due to high lipophilicity. Recently, the complete structure of ATP synthase was first reported in the Journal of Science. Objective: The study aimed to design, synthesise and carry out biological evaluation of antituberculosis agents based on the structure of bedaquiline. Methods: The mode of action of bedaquiline and ATP synthase was determined by molecular docking, and a series of low lipophilic bedaquiline derivatives were synthesized. The inhibitory activities of bedaquiline derivatives towards Mycobacterium phlei 1180 and Mycobacterium tuberculosis H37Rv were evaluated in vitro. A docking study was carried out to elucidate the structureactivity relationship of the obtained compounds. The predicted ADMET properties of the synthesized compounds were also analyzed. Results: The compounds 5c3, 6a1, and 6d3 showed good inhibitory activities (MIC=15.62 ug.mL-1). At the same time, the compounds 5c3, 6a1, and 6d3 also showed good drug-like properties through molecular docking and ADMET properties prediction. Conclusion: The results of in vitro anti-tuberculosis activity assays, docking studies and ADMET predictions indicate that the synthesized compounds have potential antifungal activity, with compounds 6a1 being further optimized and developed as lead compounds.

New hetero annulated indoles were synthesized and structurally characterized by spectral means. In order to understand the nature of interactions of these molecules, we carried out molecular docking studies using the protein kinase CK2 inhibitors. The docking results provided some useful information for the futuredesign of more potent inhibitors. The in vitro cytotoxicity was evaluated for all the new compounds by MTT assay against HeLa and compared with the standard drug ellipticine. All the compounds showed moderate to potent activity against the cell lines. The preliminary structure–activity relationships were carried out.

This study focuses on the design, synthesis, biological evaluation, and computer-aided structure-activity relationship (SAR) analysis for a novel group of aromatic triazine-methylpiperazines, with an hydantoin spacer between 1,3,5-traizine and the aromatic fragment. New compounds were synthesized and their affinities for serotonin 5-HT6, 5-HT1A, 5-HT2A, 5-HT7, and dopamine D2 receptors were evaluated. The induced-fit docking (IFD) procedure was performed to explore the 5-HT6 receptor conformation space employing two lead structures. It resulted in a consistent binding mode with the activity data. For the most active compounds found in each modification line, anti-obesity and anti-depressive-like activity in vivo, as well as “druglikeness” in vitro, were examined. Two 2-naphthyl compounds (18 and 26) were identified as the most active 5-HT6R agents within each lead modification line, respectively. The 5-(2-naphthyl)hydantoin derivative 26, the most active one in the series (5-HT6R: Ki = 87 nM), displayed also significant selectivity towards competitive G-protein coupled receptors (6–197-fold). Docking studies indicated that the hydantoin ring is stabilized by hydrogen bonding, but due to its different orientation, the hydrogen bonds form with S5.44 and N6.55 or Q6.58 for 18 and 26, respectively. Compound 26 exerted anxiolytic-like and antidepressant-like activities. Importantly, it demonstrated anti-obesity properties in animals fed palatable feed, and did not show toxic effects in vitro.

A class of 1-((benzo[d]thiazol-2-ylamino)(phenyl)methyl)naphthalen-2-ol derivatives (4a-t) has been synthesized in good yields through a three component coupling reaction. The newly synthesized compounds were evaluated for their in vitro antiproliferative activity against five cell lines such as DU145 (human prostate cancer), MDA-MB-B231 (human breast cancer), SKOV3 (human ovarian cancer), B16-F10 (mouse skin melanoma) and CHO-K1 (Chinese hamster ovary cells), a noncancerous cell line. In vitro inhibitory activity indicates that compounds 4a, 4b, 4c, 4d, 4g, 4j, and 4o exhibited potent anti-proliferative behavior. Among them, compounds 4g, 4j and 4o found to be the most active members exhibiting remarkable growth inhibitory activity. Molecular docking facilitates to investigate the probable binding mode and key active site interactions in tubulins α and β proteins. The docking results are complementary to experimental results.

<p class="Abstract">The present study aimed at the evaluation of anti-hyperglycemic and hepatoprotective potential of a new drug candidate, 5-[(4-chlorophenoxy) methyl]-1,3,4-oxadiazole-2-thiol (OXCPM) through in vitro and in vivo assays, respectively. The compound displayed excellent dose-dependent ɑ-amylase (28.0-92.0%), ɑ-glucosidase (40.3-93.1%) and hemoglobin glycosylation (9.0%-54.9%) inhibitory effects and promoted the uptake of glucose by the yeast cells (0.2 to 26.3%). The treatment of the isoniazid- and rifampicin- (p.o., 50 mg/kg of each) intoxicated rats with OXCPM (100 mg/kg, p.o.) resulted in restoring the normal serum levels of the non-enzymatic (total bilirubin, total protein and albumin) and bringing about a remarkable decrease in the levels of enzymatic (alanine transaminases, aspartate transaminases and alkaline phosphatase) biomarkers. The molecular docking studies indicated high binding affinity of the compound for hyperglycemia-related protein targets; fructose-1,6-bisphosphatase, beta<sub>2</sub>-adrenergic receptors and glucokinase. The results indicate that OXCPM may not only reduce hyperglycemia by enzyme inhibition but also the disease complications through protection of hemoglobin glycosylation and hepatic injury.</p><p class="Abstract"><strong>Video Clip of Methodology:</strong></p><p class="Abstract">Glucose uptake by yeast cells:   4 min 51 sec   <a href="https://www.youtube.com/v/8cJkuMtV0Wc">Full Screen</a>   <a href="https://www.youtube.com/watch?v=8cJkuMtV0Wc">Alternate</a></p>
