Novel Cyclopropapyrroloindole Derivative (AT-3510) Bearing Methoxycarbonyl and Trifluoromethyl Groups
摘要:
The seco-Cl 3-methoxycarbonyl-2-trifluoromethylcyclopropapyrroloindole (MCTFCPI) derivatives dl- and/or (S)-10 carrying various acyl moieties at the NG-position were synthesized along with their prodrugs (S)-12, and their antitumor activity was evaluated. Among these derivatives, AT-3510 [(S)-12m], the novel prodrug MCTFCPI derivative carrying a 5-(7-methoxybenzofuran-2-ylcarbonyl)aminoindole-2-carbonyl group at the NG-position, was found to exhibit more excellent antitumor activity against human tumor xenografts than the clinical trial candidates carzelesin (6) and KW-2189 (7) and cisplatin.
