Synthesis and biological evaluation of 5-[(aryl)(1H-imidazol-1-yl)methyl]-1H-indoles: Potent and selective aromatase inhibitors
摘要:
The synthesis and the aromatase (CYP19) inhibitory activity of 5-[(aryl)(imidazol-1-yl)methyl]-1H-indoles were reported. Among the tested racemate compounds, 5-[(4-chlorophenyl)(1H-imidazol-1-yl)methyl]-1H-indole 8b emerged as a potent CYP19 inhibitor (IC50 = 15.3 nM). Chiral chromatography allowed isolation of the (+) enantiomer 8b2, which was about twice as active as the racemate (IC50 = 9 nM). (C) 2005 Elsevier Ltd. All rights reserved.

The carbonylative Suzuki cross-coupling reaction of arylboronic acid with aryl and heteroaryl iodides using polymer supported palladium-N-heterocyclic carbene complex (PS-Pd-NHC) as an efficient heterogeneous, recyclable catalyst is described. The developed catalyticsystem is found to be effective for the carbonylative coupling reaction of aryl, heteroaryl, and bicyclic heteroaryl iodides (5-iodoindole

The carbonylativeSuzukicouplingreaction of aryl boronic acid with different aryl and heteroaryliodides was carried out to synthesize various unsymmetrical biaryl ketones by using Pd/C as an efficient, heterogeneous and reusable catalyst. The catalyst exhibits remarkable activity, and its reusability was tested up to four consecutive cycles. The reaction is applicable for various aryl and heteroaryl
