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