INHIBITION OF THE GROWTH OF TUMOUR CELLS

摘要

The invention provides the use of a compound selected from compounds of the formula (2) and pharmaceutically acceptable salts thereof in which: R1 is halogen; either R2 is H and R3 is XR4 or R3 is H and R2 is XR4; X is -COCH=CH- or -CH=CHCO-; and XR4 is Formula (I) in which: R5, R6, R7, and R8 are independently H, halogen, OR9 or CH2- NR10R11 in which R9 is H or C₁-C₃ alkyl and R10 and R11 are together or independently H, pyrrolidinyl, piperidinyl, morpholinyl, -CH₂ - morpholine, 1 -ethyl-1 -piperizinyl, t- butylamino, dimethylamino or diethylamino, in the manufacture of a medicament for the inhibition of the growth of tumour cells.
