Abstract

The invention is directed to physiologically active compounds of general formula (I): wherein Het is an optionally substituted, saturated, partially saturated or fully unsaturated 8 to 10 membered bicyclic ring system containing at least one heteroatom selected from O, S or N; R1 is optionally substituted aryl, heteroaryl, alkyl, alkenyl, alkynyl, cycloalkyl or heterocycloalkyl; R2 is hydrogen, halogen, lower alkyl or lower alkoxy; Z1 is NR5; L1 is a —R6—R7— linkage (where R6 is alkylene, alkenylene or alkynylene and R7 is a direct bond, cycloalkylene, heterocycloalkylene, aryldiyl, heteroaryldiyl, —C(═Z3)—NR5—, —NR5—C(═Z3)—, —Z3—, —C(═O)—, —C(═NOR5)—, —NR5—, —NR5—C(═Z3)—NR5—, —SO2—NR5—, —NR5—SO2—, —O—C(═O)—, —C(═O)—O—, —NR5—C(═O)—O— or —O—C(═O)—NR5—); L2 is an alkylene chain substituted by hydroxy, oxo, —OR4, —O—C(═O)—R4, —N(R8)—C(═O)—R9, &#821…
