and 10b). Derivatives 4a,b, 6a,b–10a,b were tested for in vitro alkylating activity while compounds 7a, 7b and 9a were tested for in vivo antitumor activity. As determined by in vitro Preussmann tests, compounds 4, 6 and 7 possess strong alkylating activity. Compounds 10 have moderate potential for alkylation, whereas the remaining compounds 8 and 9 are only weakly active. The derivatives 7a, 7b and
(±)-O-乙酰基扁桃酰氯分别与2-羟基钠或2-羟基钠反应的产物2-羟基-5-甲基苯乙酮 被溴化并与 亚磷酸三甲酯得到Perkov产物4a和4b,Wittig型产物6a和6b以及标题为的3-膦衍生物色酮,7a 2- [1-(±)-乙酰氧基苄基] -3-(二甲氧基磷酰基)-4-氧代-4 H-色烯}和7b 2- [1-(±)-乙酰氧基苄基] -3-(二甲氧基磷酰基)-4-氧代-6-甲基-4 H-色烯}。 酯类 7a和7b经受了酸性水解 给相应的 膦酸 8a和8b,以及意外的膦酸内酯9a和9b。他们也接受了苄胺形成相应的环状膦酰基内酯盐(10a和10b)。衍生物图4a,b,图6a,b - 10a中,b是为测试体外的烷基化活性,而化合物7A,7B和图9A中为测试体内抗肿瘤活性。如通过在体外Preussmann测试中,化合物4,6和7具有强烷基化活性。化合物10具有中等潜力烷基化,而其余化合
