摘要

A compound having the formula (1) in which the ring containing E is a phenyl, a pyridine, or a pyrimidine. In formula (1) the symbol A represents (see structures) wherein the group R⁴ represents halogen, CF₃, or H, provided that the maximum number of CF₃ groups on any A is 2, and the maximum number of hydrogens on A is 2 for the A groups which together with the carbon atoms to which they are attached form 6-membered rings, and the maximum number of hydrogens on A is 1 for the A group which together with the carbon atoms to which it is attached forms a 5-membered ring. Z represents N or CH when E forms a phenyl ring, and represents CH when E forms a pyridine or pyrimidine. The groups R¹, R² and R³ and the subscripts a, b, and d are as defined in the text and claims. Pharmaceutical compositions containing a compound of formula (1) and methods of treating cancer using compounds of formula (1) are also disclosed and claimed.
