7-dihydro-7,7-(ethylenedioxy)mitomycins was synthesized and evaluated for antitumor and anticellular activities. These compounds were prepared by basic treatment of 7-methoxymitomycins with ethylene glycol, and were structurally novel mitomycin derivatives containing a masked quinone moiety. 5,6-Enol or 6-chloro derivatives of 6,7-dihydro-7,7-(ethylenedioxy)mitomycins were also prepared and the (allyloxy)carbonyl
合成了一系列的6,7-二氢-7,7-(乙二氧基)丝裂霉素并评估了其抗肿瘤和抗细胞活性。这些化合物是通过用乙二醇对7-甲氧基丝裂霉素进行碱性处理而制备的,并且是结构上新颖的包含被掩蔽的醌部分的丝裂霉素衍生物。还制备了6,7-二氢-7,7-(乙二氧基)丝裂霉素的5,6-Enol或6-氯衍生物,并证明氮丙啶氮上的(烯丙氧基)羰基是化学修饰中的有效保护基丝裂霉素。这些丝裂霉素衍生物大多数在小鼠中表现出对P388白血病的有效抗肿瘤活性,对HeLa S3细胞的抗细胞活性。
