    • The invention relates to a method for the treatment of tumors in mammals by the administration of compounds of the general formula (I) wherein A is O41 or NR42 R43 wherein R41 is hydrogen or a pharmaceutically acceptable inorganic or organic cation, or CORA wherein RA is alkyl and aryl; R42 and R43 are hydrogen, C1-C4-alkyl, cyclopropyl, cyclopentyl or cyclohexyl; or R42 is benzyl or phenethyl, optionally mono- or disubstituted by methyl, iso-propyl methoxy, fluoro, chloro, bromo, dimethylamino, trifluoromethyl or nitro and R43 is hydrogen; or R42 and R43 form a 5- or 6-membered ring; or R42 is CORB wherein RB is alkyl or aryl, —CH2N(CH3)2 or —CH2CH2COOH or CORB is a 2-acyloxymethylbenzoyl group wherein RC is methyl, ethyl, phenyl or benzyl; R42 is COORD wherein RD is C1-C4-alkyl, phenyl or benzyl; or R42 is —CH2OCO-tert.-butyl or R42 is CONRFRG wherein RF and RG are C1-C4-alkyl; or R42 is CXNHRE wherein X is O or S and RE is C1-C4-alkyl, C2-C4-alkyl functionalized with an tertiary amino group, or phenyl, optionally functionalised with a p-chloro group; or R42 is CH2NRHRI wherein RH and RI are C1-C4-alkyl and RH and RI form a morpholine ring and R43 is hydrogen, C1-C2-alkyl or cyclopropyl; R is hydrogen, C1-C4-alkyl or allyl; with the proviso that R is not hydrogen when A is OR41; R′ is hydrogen, methyl, methoxy, fluoro, chloro, bromo, cyano, nitro, azido, trifluoromethyl, or OCHxFy, wherein x=0-2, y=1-3 with the proviso that x+y=3; and that R′ is not hydrogen when R is methyl and A is OR41; R″ is hydrogen, fluoro or chloro, with the proviso that R″ is fluoro or chloro only when R′ is fluoro or chloro; R5 is hydrogen, C1-C3-alkyl; methoxy, ethoxy, thio-C1-C3-alkyl fluoro, chloro, bromo, trifluoromethyl, nitro, amino, dimethylamino or OCHxFy, or OCH2CHxFy wherein x=0-2, y=1-3 with the proviso that x+y=3 and that R5 is not fluoro or amino when A is OR41; and that R5 is hydrogen only when A is NR42 R43 and R′ is trifluoromethyl; R6 is hydrogen; or R5 and R6 taken together are methylenedioxy, or any tautomer, optical isomer or racemate thereof. The invention also comprises novel compounds, therapeutic compositions and processes for the preparation of the compounds of formula I.
