Synthesis and structure–activity relationships of taxuyunnanine C derivatives as multidrug resistance modulator in MDR cancer cells

New taxoids bearing a bulky acyloxy group at C-2, C-5, C-7, C-9, C-10, and C-14 were obtained by chemical and bio- transformations of taxuyunnanine C and its analogs. In them, compounds 3, 5, 6, 8, and 9a have significant effects of the accumulation of calcein in MDR 2780AD. Since compounds 6 and 8...
