title: New highly active taxoids from 9beta-dihydrobaccatin-9,10-acetals. Part 3.
abstract: We synthesized novel water-soluble and orally active taxane analogues, 7-deoxy-9beta-dihydro-9,10-O-acetal taxanes. Cytotoxicities of the synthetic compounds were greater than those of paclitaxel and docetaxel, especially against resistant cancer cell lines expressing P-glycoprotein. In addition, some compounds showed potent antitumor effects against B16 melanoma BL6 in vivo by both iv and po administration.
