Design and development of Isatin-triazole hydrazones as potential inhibitors of microtubule affinity-regulating kinase 4 for the therapeutic management of cell proliferation and metastasis
摘要:
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 mu M, 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. (C) 2018 Elsevier Masson SAS. All rights reserved.
A sequential multistep reaction toward 5-trifluoromethylthio-1,2,3-triazoles has been established, starting from alkynes, organoazides, S8, and (trifluoromethyl)trimethylsilane (TMSCF3). This reaction features mild conditions, easy operation, and readily available substrates.
This invention relates to novel substituted triazolophthalazines and pharmaceutically acceptable salts thereof. This invention also provides compositions comprising a compound of this invention and the use of such compositions in methods of treating diseases and conditions that are beneficially treated by administering selective α5 receptor partial or full inverse agonists.

We synthesized 1,2,3-triazoles via the cyclization of 2,3-dibromopropionates with benzyl azides. Bismuth chloride is an efficient catalyst, and the reaction is accelerated by weak bases such as sodium acetate. A variety of functional groups are compatible with this catalytic protocol, and it takes advantage of oxygen stable catalyst and substrates because the reactive dibromides are saturated.
