culture with the aim of comparing their activity with that of N alpha-(4-amino-4-deoxypteroyl)-N delta-hemiphthaloyl-L-ornithine, a potent antifolate whose side chain likewise contains a hydrophobic aromatic ring with an acid group on the ring. All three anilides were potent DHFR inhibitors, with activity comparable to MTX and AMT. The gamma-(m-boronoanilide) displayed growth inhibitory potency similar
制备了甲氨蝶呤(MTX)的迄今未知的γ-(间羧基苯胺)和γ-(间硼酰苯胺)衍生物以及氨蝶呤(AMT)的γ-(间羧基苯胺)衍生物,并作为二氢叶酸还原酶(DHFR)的抑制剂进行了测试。 ),并作为培养物中细胞生长的抑制剂,目的是将其活性与N alpha-(4-氨基-4-deoxypteroyl)-N delta-hemiphthaloylyl-L-ornithine的活性进行比较,后者是一种有效的抗叶酸药物,其侧链同样含有一个在环上带有酸性基团的疏水性芳香环。所有三种苯甲酰胺都是有效的DHFR抑制剂,其活性可与MTX和AMT媲美。γ-(间甲硼酰基苯胺)的生长抑制能力类似于半邻苯二甲酰鸟氨酸类似物,IC50仅为0.7 nM。该化合物是迄今为止测试的MTX中最有效的γ-酰胺,也是在侧链带有B(OH)2基团的抗叶酸剂的第一个报道实例,并且由于其具有通过与活性位点上的富电子的OH或NH2基团反应形成稳
