title: Retinoic acid metabolism inhibition by 3-azolylmethyl-1H-indoles and 2, 3 or 5-(alpha-azolylbenzyl)-1H-indoles.
abstract: Among a library of 70 azoles, 8 indole derivatives substituted in the 2-, 3- or 5- position with an azolylmethyl or alpha-azolylbenzyl chain were evaluated for retinoic acid (RA) metabolism inhibitory activity. The most active inhibitors identified in this study were 5-bromo-1-ethyl-3-methyl-2-[(phenyl)(1H-1,2,4-triazol-1-yl)methyl]-1H-indole (3) (68.9% inhibition) and 5-bromo-1-ethyl-2-[(4-fluorophenyl) (1H-1,2,4-triazol-1-yl)methyl]-3-methyl-1H-indole (6) (60.4% inhibition). At the same concentration (100 microM) ketoconazole exerted similar inhibitory effect (70% inhibition).
