摘要:
Parallel synthesis of the C-terminal-modified DAPT (1) derivatives was accomplished utilizing our novel resin 7. Condensation reaction of the N-acylamino acid 10 with the amines 11a-o proceeded smoothly to give the corresponding amides 6a-o without any epimerization. Among the analogues, the benzophenonemethyl amide derivative 6o showed 30 times more potent activity than the original DAPT (1). (C) 2004 Elsevier Ltd. All rights reserved.
