Abstract: The discovery of potent STAT3 inhibitors has gained noteworthy impetus in the last decade. In line with this trend, considering the proven biological importance of 1,2,4-triazoles, herein, we are reporting the design, synthesis, pharmacokinetic profiles, and in vitro anticancer activity of novel C3-linked 1,2,4-triazole-N-arylamide hybrids and their in silico proposed mechanism of action via inhibition of STAT3. The 1,2,4-triazole scaffold was selected as a privilege ring system that is embedded in core structures of a variety of anticancer drugs which are either in clinical use or still under clinical trials. The designed 1,2,4-triazole derivatives were synthesized by linking the triazole-thione moiety through amide hydrophilic linkers with diverse lipophilic fragments. In silico study to predict cytotoxicity of the new hybrids against different kinds of human cancer cell lines as well as the non-tumor cells was conducted. The multidrug-resistant human breast adenocarcinoma cells (MDA-MB-231) was found most susceptible to the cytotoxic effect of synthesized compounds and hence were selected to evaluate the in vitro anticancer activity. Four of the designed derivatives showed promising cytotoxicity effects against selected cancer cells, among which compound 12 showed the highest potency (IC50 = 3.61?μM), followed by 21 which displayed IC50 value of 3.93?μM. Also, compounds 14 and 23 revealed equipotent activity with the reference cytotoxic agent doxorubicin. To reinforce these observations, the obtained data of in vitro cytotoxicity have been validated in terms of ligand–protein interaction and new compounds were analyzed for ADMET properties to evaluate their potential to build up as good drug candidates. This study led us to identify two novel C3-linked 1,2,4-triazole-N-arylamide hybrids of interesting antiproliferative potentials as probable lead inhibitors of STAT3 with promising pharmacokinetic profiles.

In this paper, novel 2-((5-amino-1,3,4-thiadiazol-2-yl)thio)-N-arylacetamide derivatives (7a–l) are designed, synthesized, and evaluated in vitro for their urease inhibitor activities. The compounds are synthesized efficiently in three steps in high isolated yields from amines, 2-chloroacetyl chloride, hydrazinecarbothioamide, and carbon disulfide. The molecular docking simulation were performed using AutoDock4 by docking all synthesized compound and standard inhibitors into the crystal structure of Jack bean urease. Comparison between the urease inhibitory activity of compounds 7a–l with the IC50 of (2.85–5.83 μM) and thiourea and hydroxyurea as standards inhibitors with the IC50 of (22.00 and 100.00 μM, respectively) proved the high activity of the synthesized compounds against the mentioned enzyme. Docking results were in good agreement with experimental results and indicate that synthesized compounds could interact well with the active site of the urease enzyme and among all; compound 7j shows more favorable interactions with the active site which confirm its great inhibitory activity with IC50 of 2.85 μM. Therefore, compound 7j might be a promising candidate for further evaluation.

The present work reports the synthesis and biological activity of a series of 14 benzimidazole derivatives designed to act on the enzyme triosephosphate isomerase of Trypanosoma cruzi (TcTIM). This enzyme is involved in the metabolism of glucose, the only source of energy for the parasite. In this study, we found four compounds that inhibit TcTIM moderately and lack inhibitory activity against human TIM (HsTIM). In vitro studies against T. cruzi epimastigotes showed two compounds that were more active than the reference drug nifurtimox, and these presented a low cytotoxic effect in mouse macrophages (J744 cell line).
