A synthetic model for the metal binding site of bleomycin with a 4-methoxypyridine nucleus and atert-butyl group is shown to be comparable to bleomycin in terms of dioxygen activation. This model ligand is coupled with a DNA affinity moiety, tetrapeptide S, to afford a mandesigned bleomycin which exhibits potent DNA cleaving activityin vitro.
博来霉素具有4-甲氧基吡啶核和惰性丁基的金属结合位点的合成模型显示在双氧活化方面与博来霉素相当。该模型配体与DNA亲和力部分四肽S偶联,以提供人工设计的博来霉素,其在体外表现出有效的DNA切割活性。
