The synthesis and biological evaluation of N-[4-(2-trans-[([2,6-diamino-4(3H)-oxopyrimidin-5-yl]methyl)thio]cyclobutyl)benzoyl]-L-glutamic acid (1) is reported. Compound 1 is a potent dihydrofolate reductase (DHFR) inhibitor (Kj = 12 nM) with excellent in vitro cell culture growth inhibition (L1210, IC50 = 29 nM). Protection experiments showed that the cell growth inhibitory activity was due to DHFR
N- [4-(2-反式-[([[2,6-二氨基-4(3 H)-氧嘧啶丁-5-基]甲基]硫代]环丁基)苯甲酰基] -L-谷氨酸的合成及生物学评价(1)报道。化合物1是有效的二氢叶酸还原酶(DHFR)抑制剂(K j = 12 n M),具有优异的体外细胞培养生长抑制作用(L1210,IC 50 = 29 n M)。保护实验表明,细胞生长的抑制活性是由于DHFR抑制。合成中的关键步骤是将环丁基甲基硫醇与5-溴-2,6-二氨基-4-氧嘧啶8偶联。
