Compounds of the formula IA or IB
wherein A represents an optionally substituted saturated divalent grouping which together with the two carbon atoms to which it is attached represents a fused 8, 9, 10, 11 or 12 membered carbocyclic ring selected from cycloocteno, cyclononeno, cyclodeceno, cycloundeceno and cyclododeceno; each unsubstituted or mono-, di-, tri- or tetra-substituted on carbon atoms within A by lower alkyl, lower alkylidene, C₃-C₇-cycloalkyl, hydroxy, acyloxy, oxo, lower alkoxy, aryl or aryl-lower alkoxy; and when disubstituted on the same carbon atom within A, said carbon atom in each ring is substituted by two lower alkyl or two aryl-lower alkyl groups, or by one lower alkyl or aryl-lower alkyl group and one group selected from hydroxy, lower alkoxy, aryl-lower alkoxy and acyloxy groups; or each disubstituted on the same carbon atom within A by straight chain alkylene of 2 to 6 carbon atoms forming the carbon to which the alkylene chain is attached a spiro-fused 3 to 7 membered ring; or each ring ring; R₁ represents lower alkyl, phenyl, or phenyl substituted by one or two radicals selected from lower alkyl, lower alkoxy, halogen and trifluoromethyl; or R₁ represents a five-membered unsaturated heterocyclic radical containing one hetero atom selected from sulfur, oxygen, and unsubstituted or lower alkyl substituted amino nitrogen, or a said radical containing two hetero atoms consisting of one imino nitrogen and one member selected from unsubstituted or lower alkyl substituted amino nitrogen, sulfur and oxygen; or R₁ represents an unsaturated six membered heterocyclic radical containing one or two nitrogen atoms; or R₁ represents a bicyclic benzo-fused five membered unsaturated heterocyclic radical containing one hetero atom selected from sulfur, oxygen and unsubstituted or lower alkyl substituted amino nitrogen; or R₁ represents a bicyclic benzo-fused five membered unsaturated heterocyclic radical containing two hetero atoms consisting of one imino nitrogen and one member selected from unsubstituted or lower alkyl substituted amino nitrogen, oxygen and sulfur; or R₁ represents a bicyclic benzo-fused 6-membered unsaturated heterocyclic radical containing one or two nitrogen atoms; or R₁ represents any of said heterocyclic radicals mono- or di-substituted on carbon by lower alkoxy, lower alkyl or halogen; R₂, R₃ and R₃ʹ independently represent hydrogen or lower alkyl; or tautomers thereof; or a pharmaceutically acceptable salt thereof; are useful as benzodizepine receptor modulators for the treatment of nervous system disorders. Pharmaceutical compositions, methods of preparation and certain intermediates useful as benzodiazepine receptor modulators are also disclosed.
They can be prepared for example by reacting a pyridin-4-one-3-carboxylate compound (III) with a compound of formula R-NH-NH-R₁(IV).
