The preparation of (oxodioxolenyl)methyl carbamates and their evaluation as novel nonchiral prodrug moieties for chiral primary and secondary amino functional drugs are described. 4-(Carbamoylmethyl)-2-oxo-1,3-dioxolene derivatives of 3,4-dimethoxyphenethylamine with 5-methyl, 5-phenyl, and 5-anisyl substitution (5a, 5b, and 5c) on the dioxolenone ring were prepared as model amine prodrugs by a one
描述了氨基甲酸(氧二氧杂环戊烯基)甲基酯的制备及其作为手性伯胺和仲氨基功能药物的新型非手性前药部分的评价。制备了在二氧戊烯酮环上具有5-甲基,5-苯基和5-茴香基取代基(5a,5b和5c)的3,4-二甲氧基苯乙胺的4-(氨基甲酰基甲基)-2-氧代-1,3-二氧戊烯衍生物作为模型胺的前药,其是通过一步法进行的,包括从这些氨基甲酸酯的适当取代的开环中置换对硝基苯酚,导致级联反应,从而导致母体胺药物的快速定量再生。尽管5-苯基-(1b)和5-茴香基-4-甲基-1的水解速率,pH 7.4磷酸盐缓冲液中的3-dioxol-4-en-2-one(1c)比5-甲基取代的类似物(1a)快2-3倍。该前药策略在手性纤维蛋白原受体拮抗剂L-734,217上的应用产生了一种前药,在体外大鼠和狗血浆中定量转化,母体药物在狗中的口服生物利用度为23 +/- 6%。
