To improve cytotoxicity of 10-deoxy-10-C-morpholinoethyl docetaxel analogues against various turner cell lines including resistant cells expressing P-glycoprotein (P-gp), we modified the 7-hydroxyl group to hydrophobic groups (methoxy, deoxy, 6,7-olefin, alpha -F, 7-beta -8-beta -methano, fluoromethoxy). Among these analogues. the 7-methoxy analogue showed the strongest cytotoxicity. This analogue showed potent activity against B16 melanoma BL6 in a vivo by oral administration.
