A series of 1-substituted mitosene analogues of the mitomycin antitumor antibiotics was prepared by total synthesis and screened for activity against P388 leukemia in mice. In general, analogues with moderately good leaving groups (mostly esters) at the 1 position were active, whereas analogues without such substituents were inactive or barely active. These results lend support to the idea that mitosenes
通过全合成制备一系列丝裂霉素抗肿瘤抗生素的1-取代的米托烯类似物,并筛选其抗小鼠P388白血病的活性。通常,在1位具有适度良好的离去基团(主要是酯)的类似物是有活性的,而没有这种取代基的类似物是无活性的或几乎没有活性。这些结果为以下想法提供了支持:在位置1处具有离去基团的米托涅能够以类似于丝裂霉素C的方式对DNA进行双功能烷基化。活性最高的米托涅在效力(最小有效剂量)方面与相应的叠氮基次油基相等,但它们在延长寿命方面效果不佳。
