This invention concerns the use of compounds of formula <CHEM> the N-oxides, the pharmaceutically acceptable addition salts, quaternary amines and the stereochemically isomeric forms thereof, wherein -a<1>=a<2>-a<3>=a<4>- forms a pyridinyl, pyrimidinyl, pyridazinyl or pyrazinyl with the attached vinyl group; n is 0 to 4; and where possible 5; R<1> is hydrogen, aryl, formyl, C1-6alkylcarbonyl, C1-6alkyl, C1-6alkyloxycarbonyl, substituted C1-6alkyl, or substituted C1-6alkyloxyC1-6alkylcarbonyl; each R<2> independently is hydroxy, halo, optionally substituted C1-6alkyl, C2-6alkenyl or C2-6alkynyl, C3-7cycloalkyl, C1-6alkyloxy, C1-6alkyloxycarbonyl, carboxyl, cyano, nitro, amino, mono- or di(C1-6alkyl)amino, polyhalomethyl, polyhalomethyloxy, polyhalomethylthio, -S(=O)pR<6>, -NH-S(=O)pR<6>, -C(=O)R<6>, -NHC(=O)H, -C(=O)NHNH2, -NHC(=O)R<6>,-C(=NH)R<6> or a 5-membered heterocyclic ring; p is 1 or 2; L is optionally substituted C1-10alkyl, C2-10alkenyl, C2-10alkynyl or C3-7cycloalkyl; or L is -X-R<3> wherein R<3> is optionally substituted phenyl, pyridinyl, pyrimidinyl, pyrazinyl or pyridazinyl; X is -NR<1>-, -NH-NH-, -N=N-, -O-, -C(=O)-, -CHOH-, -S-, -S(=O)- or -S(=O)2-; Q is hydrogen, C1-6alkyl, halo, polyhalo-C1-6alkyl or an optionally substituted amino group; Y represents hydroxy, halo, C3-7cycloalkyl, optionally substituted C1-6alkyl, C2-6alkenyl or C2-6alkynyl, C1-6alkyloxy, C1-6alkyloxycarbonyl, carboxyl, cyano, nitro, amino, mono- or di(C1-6alkyl)amino, polyhalomethyl, polyhalomethyloxy, polyhalomethylthio, -S(=O)pR<6>, -NH-S(=O)pR<6>, -C(=O)R<6>, -NHC(=O)H, -C(=O)NHNH2, -NHC(=O)R<6>,-C(=NH)R<6> or aryl; aryl is optionally substituted phenyl; Het is an optionally substituted heterocyclic radical; for the manufacture of a medicine for the treatment of subjects suffering from HIV (Human Immunodeficiency Virus) infection. |
