Facile Synthetic Access to and Biological Evaluation of the Macrocyclic Core of Apoptolidin
摘要:
[GRAPHICS]Oxidative cleavage of the C-20/C-21 bond in apoptolidin (1) provides two fragments of similar complexity, facilitating a divide-and-diversify strategy for the determination of the structural basis for apoptolidin's biological activity, the remarkably selective induction of apoptosis in sensitive cell lines. The ability of compounds derived from this cleavage to inhibit mitochondrial F0F1-ATPase is reported.
Toward a Structure−Activity Relationship for Apoptolidin: Selective Functionalization of the Hydroxyl Group Array
摘要:
[GRAPHICS]To investigate the structural basis for the exceptional selectivity and activity of apoptolidin (1), a strategy has been devised that allows for selective functionalization of seven of its eight hydroxyl groups based on progressive silyl protection, derivatization, and deprotection. The syntheses of these derivatives and their ability to inhibit F0F1-ATPase are reported.
