Semisynthetic Analogues of the Microtubule-Stabilizing Agent Discodermolide: Preparation and Biological Activity
摘要:
A series of 12 semisynthetic discodermolide analogues, 2-13, have been prepared using natural (+)discodermolide (1) and evaluated for in vitro cytotoxicity against cultured murine P-388 leukemia and A-549 human adenocarcinoma cells. These semisynthetic analogues showed a significant variation of cytotoxicity and confirmed the importance of the C-7 through C-19 molecular fragment for potency. Specifically, these analogues suggested the importance of the C-11 and C-17 hydroxyl groups and the C-13 double bond for the potency of discodermolide. The preparation, structure elucidation, and biological activity of these new analogues are described.
Acetylated Analogues of the Microtubule-Stabilizing Agent Discodermolide: Preparation and Biological Activity
摘要:
A series of eight discodermolide acetates have been prepared using natural (+)-discodermolide and evaluated for in vitro cytotoxicity against the cultured murine P-388 leukemia cells. The acetylated analogues showed a significant variation of cytotoxicity and suggested the importance of C-11 and C-17 hydroxyl groups for potency. The preparation and structure elucidation of the new analogues are described.
