novel bleomycin (BLM) analogs were prepared by totalsynthesis to permit the evaluation of the role of individual thiazole moieties in the processes of bleomycin-mediated oxygen activation and DNA degradation. Each of the compounds was structurally related to deglycobleomycin demethyl A 2 but contained an S-methyl-L-cysteine moiety in lieu of one of the two thiazoles normally present in bleomycin
通过全合成制备了两种结构新颖的博来霉素 (BLM) 类似物,以评估单个噻唑部分在博来霉素介导的氧活化和 DNA 降解过程中的作用。每种化合物在结构上都与去甘博来霉素脱甲基 A 2 相关,但含有 S-甲基-L-半胱氨酸部分,代替了通常存在于博来霉素中的两种噻唑中的一种
