New selective nonsteroidal aromatase inhibitors: Synthesis and inhibitory activity of 2,3 or 5-(α-azolylbenzyl)-1H-indoles
摘要:
Six azolyl substituted indoles were synthesized and tested for their activity to inhibit two P450 enzymes: P450 arom and P450 17 alpha. It was observed that the introduction of alpha-imidazolylbenzyl chain at carbon 3 or 5 on indole nucleus led to very active molecules. Compounds 22, 23 and especially 33 demonstrate very high potential against P450 arom. Under our assay conditions of high substrate concentration the IC50 are 0.057, 0.0785 and 0.041 mu M,respectively. These compounds are moderate inhibitors against P450 17 alpha.

Vinylindoles and vinylpyrroles were prepared from their corresponding aldehydes or ketones using the Peterson olefination, or by use of the Nysted reagent, a commercially available gem‐dimetallic compound. The two methods provide efficient and convenient access to these useful heterocyclic 1,3‐diene systems. J. Heterocyclic Chem., (2011).
An efficient regioselective C-3 acylation of free indoles (N-H) has been accomplished via oxidative decarbethoxylation of easily available ethyl arylacetates using Cu(OAc)2 and KOtBu in DMSO.

An efficient palladium-catalyzed synthesis of 3-acylindoles using free (N–H) indoles and nitriles has been developed. The acylation reaction proceeded well under the Pd(OAc)2/2,2′-bipyridine system and with d-(+)-camphorsulfonic acid as the additive. A possible mechanism involving carbopalladation of nitriles and subsequent hydrolysis of ketimines is proposed.
