comprehensive SAR investigation of the C2-position of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) monomer antitumor agents is reported, establishing the molecular requirements for optimal in vitro cytotoxicity and DNA-binding affinity. Both carbocyclic and heterocyclic C2-aryl substituents have been studied ranging from single arylrings to fused ringsystems, and also styryl substituents, establishing across
Compounds of formula (I) : formula (I) and salts, solvates, chemically protected forms, and prodrugs thereof, are disclosed wherein R2 is selected from: an optionally substituted napthyl group; an optionally substituted thiophenyl or furanyl group; and a phenyl group substituted by: one or more chloro or fluoro groups; an ethyl or propyl group; a 4-t-butyl group; a 2-methyl group; or two methyl groups in the 2- and 6- positions.
