title: Synthesis of 6- or 4-functionalized indoles via a reductive cyclization approach and evaluation as aromatase inhibitors.
abstract: Two new series of benzonitrile derivatives on position 6 or 4 of indole ring were successfully synthesized via a Leimgruber-Batcho reaction. All the compounds were evaluated in vitro on the inhibition of aromatase (CYP19) and 17alpha-hydroxylase-C17,20-lyase (CYP17). The racemate, 4-[(1H-imidazol-1-yl)(1H-indol-4-yl)methyl]benzonitrile 9, showed high level of inhibitory activity towards CYP19 (IC(50)=11.5 nM).
