Claim:
A compound of formula (1A)′ or (IB), or a salt thereof: wherein W is ═CH— or ═N—; R 3 is a radical selected from those of formulae A-J: wherein K is (Alk 2 ) n -Q, wherein Alk 2 are optionally substituted C 1 -C 6 alkylene, C 2 -C 6 alkenylene, or C 2 -C 6 alkynylene radicals, which may optionally terminate with or be interrupted by —O—, —S—, —S(O)—, —S(O 2 )—, —NH—, —N(CH 3 )—, or —N(CH 2 CH 3 )—; and wherein Q is hydrogen, halogen, nitrile, or hydroxyl or an optionally substituted monocyclic carbocyclic or heterocyclic radical having 3 to 6 ring atoms; or an optionally substituted bicyclic carbocyclic or heterocyclic radical having 5 to 10 ring atoms; and wherein n is 0 or 1, and wherein any unsubstituted ring carbon is optionally substituted, R 4 and R 5 are independently fluoro or chloro, or one of R 4 and R 5 is hydrogen while the other is fluoro or chloro; and R 2 , R 6 and R 7 are independently hydrogen or a radical of formula -(Alk 3 )x-(Z 2 )y-(Alk 4 ) z -H wherein x, y and z are independently 0 or 1 , Z 2 is —O—, —S—, —S(O)—, —S(O 2 )—, —NH—, —N(CH 3 )—, —N(CH 2 CH 3 )—, —C(═O)—, —0—(C═O)— or —C(═O)—O—; Alk 3 and Alk 4 are optionally substituted C 1 -C 3 alkylene, C 2 -C 3 alkenylene, or C 2 -C 3 alkynylene radicals, which may optionally terminate with or be interrupted by —O—, —S—, —S(O)—, —S(O 2 )—, —NH—, —N(CH 3 )—, or —N(CH 2 CH 3 )—.
