Based on our previous research, thirty new 5-amino-1H-1,2,4-triazoles possessing 3,4,5-trimethoxyphenyl moiety were synthesized, and evaluated for antiproliferative activities. Among them, compounds IIa, IIIh, and IIIm demonstrated significant antiproliferative activities against a panel of tumor cell lines, and the promising compound IIIm dose-dependently caused G2/M phase arrest in HeLa cells. Furthermore, analogue IIa exhibited the most potent tubulin polymerization inhibitory activity with an IC50 value of 9.4 μM, and molecular modeling studies revealed that IIa formed stable interactions in the colchicine-binding site of tubulin, suggesting that 5-amino-1H-1,2,4-triazole scaffold has potential for further investigation to develop novel tubulin polymerization inhibitors with anticancer activity.

Recent target validation studies have shown that inhibition of the protein interaction between annexin A2 and the S100A10 protein may have potential therapeutic benefits in cancer. Virtual screening identified certain 3,4,5-trisubstituted 4H-1,2,4-triazoles as moderately potent inhibitors of this interaction. A series of analogues were synthesized based on the 1,2,4-triazole scaffold and were evaluated for inhibition of the annexin A2-S100A10 protein interaction in competitive binding assays. 2-[(5-{[(4,6-Dimethylpyrimidin-2-yl)sulfanyl]methyl}-4-(furan-2-ylmethyl)-4H-1,2,4-triazol-3-yl)sulfanyl]-N-[4-(propan-2-yl)phenyl]acetamide (36) showed improved potency and was shown to disrupt the native complex between annexin A2 and S100A10.

We present an efficient one-pot, three component microwave-assisted synthesis of benzo[f]pyrrolo[1,2-a]quinoline derivatives starting from benzo[f]quinoline, 2-bromo-acetophenones or 2-chloro-(N-phenyl)acetamides and electron-deficient alkynes. This synthetic strategy provides a direct and easy access to a range of novel benzo[f]pyrrolo[1,2-a]quinoline derivatives. The method has the advantages of considerable shorter reaction time, reduced solvent consumption, operational simplicity and minimal impact on the environment. Nine new benzo[f]pyrrolo[1,2-a]quinoline derivatives have been synthesized with the new method and they are fully characterized.

Indoleamine 2,3-dioxygenase 1 (IDO1) is a promising target in immunomodulation of several pathological conditions, especially cancers. Here we present the synthesis of a series of IDO1 inhibitors with the novel isoxazolo[5,4-d]pyrimidin-4(5H)-one scaffold. A focused library was prepared using a 6-or 7-step synthetic procedure to allow a systematic investigation of the structure-activity relationships of the described scaffold. Chemistry-driven modifications lead us to the discovery of our best-in-class inhibitors possessing p-trifluoromethyl (23), p-cyclohexyl (32), or p-methoxycarbonyl (20, 39) substituted aniline moieties with IC50 values in the low micromolar range. In addition to hIDO1, compounds were tested for their inhibition of indoleamine 2,3-dioxygenase 2 and tryptophan dioxygenase, and found to be selective for hIDO1. Our results thus demon-strate a successful study on IDO1-selective isoxazolo[5,4-d]pyrimidin-4(5H)-one inhibitors, defining promising chemical probes with a novel scaffold for further development of potent small-molecule immunomodulators.

We herein applied the four step-synthetic route to prepare the pyridazine core attached to the various N-aryl acetamides. By this approach, a new series of pyridazine-based compounds were synthesized, characterized and evaluated for their activities against α-glucosidase enzyme. In-vitro α-glucosidase assay established that twelve compounds are more potent than acarbose. Compound 7a inhibited α-glucosidase with the IC50 value of 70.1 μM. The most potent compounds showed no cytotoxicity against HDF cell line. Molecular docking and kinetic studies were performed to determine the modes of interaction and inhibition, respectively.
