Synthesis and biological evaluation of 5-[(aryl)(1H-imidazol-1-yl)methyl]-1H-indoles: potent and selective aromatase inhibitors

Bioorg Med Chem Lett. 2006 Mar 1;16(5):1134-7. doi: 10.1016/j.bmcl.2005.11.099. Epub 2005 Dec 27.

Abstract

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 (IC(50)=15.3 nM). Chiral chromatography allowed isolation of the (+) enantiomer 8b2, which was about twice as active as the racemate (IC(50)=9 nM).
