The design and synthesis of 1a - e functional models for bleomycin are described in which AMPHIS, a metal-complexing model of bleomycin, and a distamycin moiety are connected with a series of linkers. Studies on the rates of DNA breakage and a mobility assay of DNA cleavage ability show that trans-1,2-disubstituted cyclopropane units are the best linkers amongst those examined.
