antagonists methotrexate and 10-ethyl-10-deazaaminopterin are oxidized in vivo to their 7-hydroxy derivatives. A specific cyanation at the C-7 position of the pteridine ring system using diethyl phosphorocyanidate converted the dimethyl esters of methotrexate and 10-ethyl-10-deazaaminopterin to the corresponding 7-cyano dimethyl ester derivatives, which were hydrolyzed to the 7-hydroxy metabolites.
有效的叶酸拮抗剂甲氨蝶呤和10-乙基-10-去氮杂氨基蝶呤在体内被氧化为其7-羟基衍生物。使用二乙基磷腈基酯在蝶啶环系统的C-7位进行特定的氰化反应,将甲氨蝶呤和10-乙基-10-去氮杂氨基蝶呤的二甲基酯转化为相应的7-氰基二甲基酯衍生物,将其水解为7-羟基代谢物。
