4-diamino-6-pteridinyl)methyl]amino]bicyclo[2.2.2]octane-1-carbonyl]-L-glutamic acid (1) was synthesized and tested for antifolate activity. N-(4-Aminobicyclo[2.2.2]octane-1-carbonyl-L-glutamic acid dimethyl ester (6), the side chain precursor to subject compound 1, was synthesized readily via reported bicyclo[2.2.2]octane-1,4-dicarboxylic acid monoethyl ester (2). The side chain precursor 6 was alkylated by 6-(bromomethyl)-2
合成了N- [4-[[2,4-二氨基-6-哌啶基)甲基]氨基]双环[2.2.2]辛烷-1-羰基] -L-谷氨酸(1),并测试了其抗叶酸活性。N-(4-氨基双环[2.2.2]辛烷-1-羰基-L-谷氨酸二甲酯(6),易于通过报道的双环[2.2.2]辛烷-1合成为目标化合物1的侧链前体。 ,4-二羧酸单乙酯(2)。用6-(溴甲基)-2,4-哌啶二胺(7)烷基化侧链前体6,随后酯水解,得到1. 1叶酸L1210二氢叶酸的抗叶酸和抗肿瘤评价还原酶(DHFR)和三种肿瘤细胞系(L1210,S180和HL60)均显示其无效,尽管化合物1在结构上与氨基蝶呤非常相似,但双环化合物[2.2]。
