A compound for use as a medicine having formula (I), a pharmaceutically acceptable acid addition salt form or a stereochemically isomeric form thereof, wherein R<1> and R<2> each independently are hydrogen, C1-6alkyl or C3-6cycloalkyl; or R<1> and R<2> taken together with the nitrogen atom bearing said R<1> and R<2> may form a pyrrolidinyl, piperidinyl, morpholinyl, piperazinyl or 4-C1-4alkylpiperazinyl group; X is O or S; R<3> is hydrogen or C1-6alkyl; R<4>, R<5> and R<6> each independently are hydrogen, halo, C1-6alkyl, C1-6alkyloxy, nitro, trifluoromethyl, cyano, aminomethyl, carboxyl, C1-4alkyloxycarbonyl, C1-4alkyl-carbonyl, aminocarbonyl or hydroxy; R<7> is hydrogen or halo; and R<8>, R<9> and R<10> each independently are hydrogen, halo, C1-6alkyl, C1-6alkyloxy, nitro, hydroxy, trifluoromethoxy, 2,2,2-trifluoroethoxy, (trifluoromethyl)carbonyl, aminocarbonyl, (cyclopropyl)carbonyl or a radical C1-6alkyl-(C=Y)- wherein =Y represents =O, =N-OH, =N-OCH3, =N-NH2 or =N-N(CH3)2; provided that (1) R<1> is other than n-propyl when R<2>, R<3>, R<4>, R<5>, R<6>, R<7>, R<9> and R<10> represent hydrogen, R<8> represents 4-ethoxy and X represents oxygen, and (2) X is other than sulfur, when R<1>, R<2>, R<3>, R<6>, R<7>, R<8>, R<9> and R<10> represent hydrogen and R<4> and R<5> represent 3,4-dimethoxy. Novel compounds, pharmaceutical compositions containing said compounds of formula (I), and processes for preparing said compositions. |
