Introducing the mercaptoethyl group at the 7-N position of mitomycin C 1 has led to the isolation of 7-N,7'-N'-dithiodiethylenedimitomycin C 2. The compound 2 showed excellent antitumor activity against sarcoma 180 (sc-ip) and leukemia P388 (ip-ip) in mice. As an extension of this study, we synthesized mitomycin dimers with symmetrical disulfide and mitomycin derivatives with unsymmetrical disulfide
在丝裂霉素C 1的7-N位置引入巯基乙基导致分离出7-N,7'-N'-二硫代二亚乙基二丝裂霉素C2。化合物2对肉瘤180(sc-ip)和小鼠中的P388白血病(ip-ip)。作为这项研究的扩展,我们合成了在对称7-N侧链上具有对称二硫键的丝裂霉素二聚体和在非对称二硫键上的丝裂霉素衍生物。在这些化合物中,带有γ-L-谷氨酰基-L-半胱氨酰甘氨酸乙酯的水溶性缀合物3对肉瘤180和白血病P388的疗效远比1更好。在随后的3个潜在同类物研究阶段,化合物4(水溶性:大于500 mg / ml),命名为KW2149,
