The synthesis and evaluation of N-[4-[5-(2,4-diamino-6-oxo-1,6-dihydropyrimidin-5-yl)-2-(2,2,2-trifluoroacetyl)pe ntyl]benzoyl]-L-glutamic acid (2) as an inhibitor of glycinamide ribonucleotide transformylase (GAR Tfase) and aminoimidazole carboxamide ribonucleotide transformylase (AICAR Tfase) are reported. The inhibitor 2 was prepared in a convergent synthesis involving C-alkylation of methyl 4-(4
N- [4- [5-(2,4-二氨基-6-氧代-1,6-二氢嘧啶-5-基)-2-(2,2,2-三氟乙酰基)戊基]苯甲酰基的合成和评价报道了作为甘氨酰胺核糖核苷酸转化酶(GAR Tfase)和氨基咪唑羧酰胺核糖核苷酸转化酶(AICAR Tfase)抑制剂的] -L-谷氨酸(2)。抑制剂2是通过收敛合成制备的,该合成包括将4-(4,4,4-三氟-3-二甲基肼基丁基)苯甲酸甲酯与1-氯-3-碘丙烷的C-烷基化,然后构建嘧啶酮环。发现化合物2是重组人GAR Tfase(K(i)= 0.50 microM)的有效抑制剂,而它对大肠杆菌GAR Tfase和重组人AICAR Tfase没有活性(K(i)> 100 microM)。 。化合物2表现出适度的特性
