substituted analogues were built up stepwise from p-aminobenzoic acid or analogues. The compounds were tested as inhibitors of methotrexate uptake as a measure of binding to the reduced folate transport system, as inhibitors of glycinamide ribonucleotide transformylase, as substrates for folylpolyglutamate synthetase, and as inhibitors of tumor cell growth in cell culture. With the exception of 2'-F substituent
这项研究描述了嘌呤从头生物合成抑制剂的合成及其体外抗肿瘤活性,这些抑制剂是N- [4-[[3-(2,4-diamino-1,6-dihydro-6-oxo-5-pyrimidinyl )丙基]氨基]苯甲酰基-L-谷氨酸(5-DACTHF)。通过关键的还原胺化步骤,由保护的嘧啶基丙醛和取代的谷氨酸苯甲酸酯部分合成苯环取代的类似物。由对氨基苯甲酸或类似物逐步构建嘧啶和连接链取代的类似物。测试这些化合物作为甲氨蝶呤摄取的抑制剂,作为与减少的叶酸转运系统的结合的量度,作为甘氨酰胺核糖核苷酸转化酶的抑制剂,作为叶酰聚谷氨酸合成酶的底物,以及作为细胞培养中肿瘤细胞生长的抑制剂。除了2' -F取代基,环取代的类似物的活性低于母体化合物。用碳,硫或氧替代10-氮对体外生物活性的影响不到2倍。嘧啶环上2位的四原子连接链和一个氨基对于良好的活性很重要。
