In the past five years, our team had been committed to click chemistry research, exploring the biological activity of 1,2,3-triazole by synthesizing different target inhibitors. In this study, a series of novel indole-2-one derivatives based on 1,2,3-triazole scaffolds were synthesized for the first time, and their inhibitory activity on vascular endothelial growth factor receptor-2 (VEGFR-2) was tested. Most of the compounds had shown promising activity in the VEGFR-2 kinase assay and had low toxicity to human umbilical vein endothelial cells (HUVECs). The compound 13d (IC50 = 26.38 nM) had better kinase activity inhibition ability than sunitinib (IC50 = 83.20 nM) and was less toxic to HUVECs. Moreover, it had an excellent inhibitory effect on HT-29 and MKN-45 cells. On the one hand, by tube formation assay, transwell, and Western blot analysis, compound 13d could inhibit VEGFR-2 protein phosphorylate on HUVECs, thereby inhibiting HUVECs migration and tube formation. In vivo study, the zebrafish model with VEGFR-2 labeling also verified that compound 13d had more anti-angiogenesis ability than sunitinib. On the other hand, molecular docking and molecular dynamics (MD) simulation results showed that compound 13d could stably bind to the active site of VEGFR-2. Based on the above findings, compound 13d could be considered an effective anti-angiogenesis drug and has more development value than sunitinib.

Microtubule affinity-regulating kinase 4 (MARK4) is a potential drug target as the same is found to be over expressed in several types of cancers. In search of effective MARK4 inhibitors, we have synthesized and characterized Isatin-triazole hydrazones (9a-i) and evaluated their inhibitory potential. Of all the compounds, 9g showed better binding affinity and enzyme inhibition potential in sub micromolar range. Human serum albumin (HSA) binding assay suggested an easy transportation of 9g in blood stream due to its binding affinity. In vitro anticancer studies performed on MCF-7, MDA-MB-435s and HepG2 cells using 9g showed inhibition of cell proliferation and cell migration. Further, 9g induces apoptosis in these cancerous cells, with IC50 values of 6.22, 9.94 and 8.14 μM, respectively. Putatively, 9g seems to cause oxidative stress resulting in apoptosis. Functional assay of 9g with a panel of 26 kinases showed MARK4 specific profile. In conclusion, 9g seems to possess an effective inhibitory potential towards MARK4 adding an additional repertoire to anticancer therapeutics.
