Application Number:	09/831,808
Claims:	1. A compound of formula ##STR11## or a N-oxide, a pharmaceutically acceptable salt, or a stereochemically isomeric form thereof, wherein --a.sup.1.dbd.a.sup.2 --a.sup.3.dbd.a.sup.4 -- represents a bivalent radical of formula with the proviso that compounds wherein L is --X--R.sup.3, X is --NH--; R.sup.1 is hydrogen; --a.sup.1.dbd.a.sup.2 --a.sup.3.dbd.a.sup.4 -- represents a bivalent radical of formula (a-1); n is 0 or 1 and R.sup.2 is selected from amino or nitro and R.sup.3 is phenyl, and the compound N,N'-dipyridinyl-(1,3,5)-triazine-2,4-diamine, are not included. 2. A compound as claimed in claim 1 wherein L is --X--R.sup.3, --X-- is --O-- or --NH-- and R.sup.3 is phenyl substituted with two or three substituents each independently selected from chloro, bromo, cyano or methyl. 3. A pharmaceutical composition comprising a pharmaceutically acceptable carrier and a therapeutically effective amount of compound as claimed in claim 1. 4. A process for preparing a pharmaceutical composition as claimed in claim 3 comprising mixing a therapeutically effective amount of said compound with a pharmaceutically acceptable carrier. 5. A process for preparing a compound as claimed in claim 1, comprising a) reacting an intermediate of formula (II) with an amine derivative of formula (III) and subsequently reacting the resulting intermediate of formula (IV) with an intermediate of formula (V) in a reaction-inert solvent in the presence of a suitable base; ##STR13## wherein W.sup.1 is a suitable leaving group; b) reacting an intermediate of formula (VI) with an intermediate of formula (VII) and subsequently reacting the resulting intermediate of formula (VIII) with an amine derivative of formula (III) in a reaction-inert solvent in the presence of a suitable base; ##STR14## wherein W.sup.1, W.sup.2 are suitable leaving groups, L.sub.a is optionally substituted C.sub.1-10 alkyl, C.sub.2-10 alkenyl, C.sub.2-10 alkynyl, or C.sub.3-7 cycloalkyl; or optionally, interconverting a first compound of formula (I') to yield a second compound of formula (I'), and further, optionally, converting compounds of formula (I') into a therapeutically active non-toxic acid addition salt by treatment with an acid, or into a therapeutically active non-toxic base addition salt by treatment with a base, or, converting the acid addition salt form into the free base by treatment with alkali, or converting the base addition salt into the free acid by treatment with acid; and, optionally, preparing stereochemically isomeric forms or N-oxides thereof. 6. The combination of a compound as defined in claim 1 and another antiretroviral compound. 7. A combined preparation for simultaneous, separate or sequential use in anti-HIV treatment, comprising a product containing (a) a compound as defined in claim 1, and (b) another antiretroviral compound. 8. A pharmaceutical composition comprising a pharmaceutically acceptable carrier and as active ingredients (a) a compound as defined in claim 1, and (b) another antiretroviral compound. 9. A method of treating a subject suffering from Human Immunodeficiency Virus (HIV) infection, comprising administering to said subject a therapeutically effective amount of a compound of formula ##STR15## or a N-oxide, a pharmaceutically acceptable salt, or a stereochemically isomeric form thereof, wherein --a.sup.1.dbd.a.sup.2 --a.sup.3.dbd.a.sup.4 -- represents a bivalent radical of formula 10. The method of claim 9 further comprising administering a therapeutically effective amount of another antiretroviral compound to said subject. 11. The method of claim 10 where said compound of formula (I) and the other antiretroviral compound are administered simultaneously, separately, or sequentially to said subject.
