[Synthesis and biological evaluation of indole derivatives acting as anti-inflammatory or antitumoral drugs].
Two axes of research have been explored, one about promising non-acidic non-steroidal anti-inflammatory derivatives, with indolin-2-one as structural core and another one about aromatase inhibitors, characterized by azolylmethyl or alpha-azolylbenzyl chain on indole nucleus. Knoevenagel reaction led to indolin-2-ones substituted by either 2,6-di-tert-butylphenol chain or 1, 4-dihydropyridine chain, revealing antioxydant or anti-inflammatory activities. Aromatase is a logical target in the treatment of hormono-dependent breast cancer in postmenopausal women. Among non steroidal inhibitors of this enzyme, diverse compounds with anilino or azaheterocyclic moiety are currently used or undergoing clinical trials. Our pharmacomodulation in azolylmethylindole or alpha-azolylbenzylindole series led to compounds with high level aromatase inhibitory activity. Work to determine their selectivity by measuring their inhibitory effect on P450 17alpha enzyme was also carried out. A first molecular modeling approach with Discover software was performed to evaluate interactions between our molecules and the catalytic site of P450cam.
