The synthesis and screening of antitumor activity in vitro (cytotoxicity) of various oxygen, nitrogen, sulfur and platinum-containing derivatives of allobetulin, including different arrangements of the double bonds in the A and B rings, penta- and hexacyclic ring A, 21-acetyl-20,28-epoxy-18α,19βH-ursane-isomeric cycle E, was carry out. (3R,5R)-19β,28-Epoxy-4,5-seco-18α-olean-3(5)-ozonide and 2,3-i
合成和筛选多种别氧白蛋白的含氧,氮,硫和铂的体外抗肿瘤活性(细胞毒性),包括A和B环,五环和六环A,21-进行了乙酰基-20,28-环氧-18α,19βH-ur烷异构体循环E。(3R,5R)-19β,28-环氧-4,5-seco-18α-olean-3(5)-臭氧化物和2,3-吲哚-21β-乙酰基-20β,28-环氧-18α,H-19β -ursane适当地显示了对黑色素瘤MeWo和白血病SR细胞的显着细胞毒活性。第一化合物的(3S,5S)-非对映异构体没有显示细胞毒性。
