A taxane derivative of the formula <CHEM> wherein R<5> and R<7> are independently selected from the group comprising phenyl, naphthalene, C1/4 H psi CHCH-, and <CHEM> provided, however, R<5> and R<7> are not both phenyl; Q is CH<7>-, (CH<7>)<7>C-, CH<7>O-, Cl, Br, F, NO<6>, <CHEM> Z is -OT<5>, T<5> is hydrogen, hydroxyl protecting group, or -COT<6>, T<6> is H, C<5>-C1/4 alkyl, C<5>-C1/4 alkenyl, C<5>-C1/4 alkynyl or monocylic aryl, Ac is acetyl, and E<5> and E<6> are independently selected from hydrogen and functional groups which increase the water solubility of the taxane derivative are useful as antitumor agents. |
