Claim:
A compound of the formula or the pharmaceutically acceptable salts thereof; wherein each of rings A and B is independently a pyridinyl optionally substituted with one or more substituents selected from the group consisting of alkyl (C 1-10 ), alkenyl (C 2-10 ), and alkynyl (C 2-10 ); ring C is an unsubstituted piperidine or is piperidine substituted only at position 4 with OH, OMe, CN, OBz, ═NOEt, or ═NOBz; wherein Y is phenyl, benzimidazole or imidazole; or is selected from the group consisting of, —(CH 2 ) m NH 2 , —(CH 2 ) m NHCH 3 , —(CH 2 ) m NH(CH 2 ) m NH 2 , —(CH 2 ) m NH(CH 2 ) m NH(CH 2 )mNH 2 , —(CH 2 ) m OH, —(CH 2 ) m CO(CH 2 ) m OH, —(CH 2 ) m CO(CH 2 ) m NH 2 , —(CH 2 ) m CO(CH 2 ) m NH(CH 2 ) m NH 2 , —(CH 2 ) m NHCO(CH 2 ) m NH 2 , —(CH 2 ) m NH (CH 2 ) m CO 2 H, —(CH 2 ) m NH (CH 2 ) m SO 2 H, —(CH 2 ) m NHCO(CH 2 ) m NH(CH 2 ) m NH 2 , —(CH 2 ) m NHCO(CH 2 ) m NH(CH 2 ) m NH(CH 2 ) m NH(CH 2 ) m NH 2 , —(CH 2 ) m NH(CH 2 ) m OH, —(CH 2 ) m CH═NOH, —(CH 2 ) m CONH(CH 2 ) m OH, —(CH 2 ) m N[(CH 2 ) m CO 2 H] 2 , —(CH 2 ) m NHCOZ and —(CH 2 ) m NH—(CH 2 ) m Z, wherein each m is independently 0-4; and Z is an optionally substituted aromatic or heteroaromatic moiety containing 5-12 ring members; L is (CR 3 2 ) 1 where each R 3 is H or alkyl wherein a single bond in alkyl may be replaced with a double or triple bond and wherein 1 is 1-6.
