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.

Paragraph 0021, (2017/01/12)
The present invention relates to synthesis of 7? Halo indole method, comprising the steps of:O-halogenated aniline, chloral hydrate and hydroxylamine hydrochloride by the Sandmeyer reaction to synthesize 7? halogenating isatin ; 7? halogenating isatin dissolved with an organic solvent, in the reducing agent by reduction reaction under the conditions of 7? Halo indole, the reducing agent is an alkali metal borohydride system, four system adopts, lithium hydride system or triethyl silane system. The beneficial effect of the invention is:in order to O-halogenated aniline and the chloral hydrate is, hydroxylamine hydrochloride as raw materials, by the Sandmeyer shall synthesis method for preparing compositions b isonitroso 7? halogenating isatin, and then by further reduction and system reduction to prepare 7? Halo indole; by the 7? Preparation halogenating isatin 7? Halo indole method, the raw material is easy to obtain, low price, higher process yield, the product purity is good, simple operation, and the like, is suitable for batch preparation 7? Halo indole.

In an effort to develop the potent anticonvulsant agents, a series of novel isatin-1-N-phenylacetamide derivatives was synthesized and screened for their in vivo anticonvulsant activity against maximal electroshock test and evaluated for their neurotoxicity by the rotarod test at the same dose levels. Ten compounds exhibited the anticonvulsant activity. 2-(5-Methyl-2,3-dioxoindolin-1- yl)-N-phenylacetamide (4b) was found to be the most potent compound of the series with an ED50 of 91.3 mg/kg, TD50 of >1,000 mg/kg, a higher protective index (PI = TD50/ED50, >11) was gained than the reference drug phenobarbital and carbamazepine. The essential structural features responsible for interaction with receptor site are established within a suggested pharmacophore. Springer Science+Business Media 2013.
