Design, synthesis, and antitumor activity-absolute configuration relationships of podophyllotoxin aza-analogues
摘要:
Optically active and racemic podophyllotoxin aza-analogues 3 approximately 7 were designed and synthesized by a highly stereoselective condensation reaction of a cyclic urethane 10 or 16 with 3,4,5-trimethoxybenzaldehyde 11 and were found to show a promising in vitro and in vivo antitumor activity.
Determination of the absolute configuration of fasidotril, a potent dual ACE/NEP inhibitor
摘要:
The absolute configuration of fasidotril has been established by a chemical correlation leading to the stereochemical assignment of the intermediate (S)-3-acetylsulfanyl-2-(benzo[1,3]dioxol-5-ylmethyl)propanoic acid. (C) 2003 Elsevier Ltd. All rights reserved.
