Preparation and pharmacological profile of 7-(α-Azolylbenzyl)-1H-indoles and indolines as new aromatase inhibitors
摘要:
Aromatase (P450 arom) is a target of pharmacological interest for the treatment of breast cancer. New series of 7-(alpha-azolylbenzyl)-1H-indoles and indolines were synthesized as non-steroidal inhibitors of P450 arom. Selectivity was studied towards P450 17alpha enzyme. The most active compound, 1-ethyl-7-[(imidazol-1-yl)(4-chlorophenyl)methyl]-1H-indole 12c exhibited promising relative potency (rp) of 336 (rp, of aminoglutethimide = 1) and most of the described azoles were active and selective towards P450 arom.

A palladium-catalyzed direct addition of arylboronic acids to unprotected 2-aminobenzonitriles has been developed, leading to a wide range of 2-aminobenzophenones with moderate to excellent yields. The transformation has broad scope and high functional group tolerance. Moreover, 2-oxoindoline-7-carbonitrile and indole-7-carbonitrile were applicable to this process for the construction of 7-benzoyl-2-oxoindolines and 7-benzoylindoles, respectively. Among the compounds examined, compound 4e possessed the most potent anticancer activity against H446 and HGC-27 in vitro, with IC50 values of 0.02 μmol L−1 and 0.09 μmol L−1, respectively, while compound 4a showed the best potent anticancer activity against SGC-7901 with an IC50 value of 0.01 μmol L−1. Furthermore, we also performed in silico molecular docking calculations to investigate the interaction mode and binding affinity between the examined compounds and their tubulin target.

Rhodium Enalcarbenoids: Direct Synthesis of Indoles by Rhodium(II)-Catalyzed [4+2] Benzannulation of Pyrroles
electrophilic rhodium enalcarbenoid which results from rhodium(II)‐catalyzeddecomposition of a new class of enaldiazo compounds. The synthetic utility of these enalcarbenoids has been successfully demonstrated in the first transition‐metal‐catalyzed [4+2] benzannulation of pyrroles, thus leading to substituted indoles. The new benzannulation has been applied to the efficientsynthesis of the natural
