Abstract

A compound of formula 301, 302, 303, 304, 305, 306, 307, 308 or 309 wherein: R1 is an alpha-oriented alkoxycarbonyl or hydroxycarbonyl radical; -A-A- is the group -CHR4-CHR5- or -CR4=CR5-; R3, R4 and R5 are independently hydrogen, halo, hydroxy, alkyl, alkoxy, hydroxyalkyl, alkoxyalkyl, hydroxy carbonyl, cyano or aryloxy; -B-B- is the group -CHR6-CHR7- or an alpha or beta- oriented group of formula III; R6 and R7 are independently hydrogen, halo, alkoxy, acyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonyl, alkyl, alkoxycarbonyl, acyloxyalkyl, cyano or aryloxy; and R8 and R9 are independently hydrogen, hydroxy, halo, alkoxy, acyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonyl, alkyl, alkoxycarbonyl, acyloxyalkyl, cyano or aryloxy, or together comprise a carbocyclic or heterocyclic ring structure, or R8 or R9 together with R6 or R7 comprise a carbocyclic or heterocyclic ring structure fused to the pentacyclic D ring.
