1. A compound of general formula I wherein Y is selected from —CRay═CRby—, —C≡C—, —CHRay—CHRby—CHRcy—, —CHRay—CRby═CRcy—, and —CHRay—C≡C—; each Ray, Rby, and Rcy is independently selected from hydrogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, and substituted or unsubstituted C2-C12 alkynyl; each R1, R2, R3, R4, and R5 is independently selected from hydrogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, and substituted or unsubstituted C2-C12 alkynyl; R6 is selected from NR8R9, and OR10; A is W is NR7; R7 is selected from hydrogen, CORa, COORa, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, and substituted or unsubstituted C2-C12 alkynyl; R8 is selected from hydrogen, CORa, COORa, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, substituted or unsubstituted C2-C12 alkynyl, and substituted or unsubstituted C4-C12 alkenynyl; R10 is selected from hydrogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, and substituted or unsubstituted C2-C12 alkynyl; each dotted line represents an optional additional bond, but when a triple bond exists between the C atoms to which R1 and R2 are attached, R1 and R2 are absent, and when a triple bond exists between the C atoms to which R3 and R4 are attached, R3 and R4 are absent; R9 is selected from hydrogen, CORa, COORa, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, substituted or unsubstituted C2-C12 alkynyl, and substituted or unsubstituted C4-C12 alkenynyl, with the proviso that when Y is —CHRay—CHRby—CHRcy— or —CHRay—CRby═CRcy— and a single or a double bond exists between the C atoms to which R3 and R4 are attached then R9 is substituted or unsubstituted C4-C12 alkenynyl; R16, R17 and R18 are independently selected from hydrogen, ORa, OCORa, OCOORa, NRaRb, NRaCORb, and NRaC(═NRa)NRaRb, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl and substituted or unsubstituted C2-C12 alkynyl; each Ra and Rb are independently selected from hydrogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C2-C12 alkenyl, substituted or unsubstituted C2-C12 alkynyl, substituted or unsubstituted aryl and substituted or unsubstituted heterocyclic group; or a pharmaceutically acceptable salt, tautomer or stereoisomer thereof.
