The present invention concerns taxane derivatives of formula I,
wherein R¹ is hydrogen, C1-8 alkyloxy, C2-8 alkenyloxy, or C2-8 alkynyloxy, each can be optionally substituted with hydroxy; R is hydroxy, -OC(O)Rx or -OC(O)ORx; R⁴ and R⁵ are independently C1-8 alkyl, C2-8 alkenyl, C2-8 alkynyl, or -Z-R⁶; p is zero or one; Z is a direct bond, C1-8 alkylene or C2-8 alkenediyl; R⁶ is aryl, substituted aryl, C3-8 cycloalkyl or heteroaryl; and Rx is C1-8 alkyl optionally, substituted with one to six same or different halogen atoms, C3-8 cycloalkyl or C2-8 alkenyl; or Rx is a radical of the formula
wherein D is a bond or C1-8 alkyl; and Ra, Rb and Rc are independently hydrogen, amino, C1-8 alkylamino, di-C1-8alkylamino, halogen, C1-8 alkyl, or C1-8 alkyloxy, their use as antitumor agents and pharmaceutical compositions containing the novel compounds.
