Popis: | Inhibitory activities towards human placental aromatase of novel pyrrolidinone and piperidinone drugs were investigated and compared with those of aminoglutethimide (AG) in vitro . All compounds showing a stronger inhibitory effect than this of AG had the following common structural feature: an imidazole side-chain in C-3 position, with a substituted or non-substituted aromatic ring in the C-2 position and an aliphatic chain ( n -butyl or n -octyl) or a phenyl moiety on the nitrogen of the pyrrolidone or piperidone ring. When the C-3 side-chain did not bear any imidazole ring, no activity was observed. Respective K i values for the competitive inhibition exerted by the more potent inhibitors 10, 11, 13 and 21 with androstenedione as substrate were 19.2, 20.3, 16.8 and 15.4 μM, respectively ( K i AG = 77.0 μM). |
