compounds were the phosphonic analogues of homo-tyrosine (K(i)=120 nM) and homo-phenylalanine (K(i)=140 nM), which even as racemic mixtures were better inhibitors in comparison with the best till now-phosphonic analogue of l-leucine (230 nM). Additional comparison of the inhibitory activity obtained for aminopeptidase N (APN, E.C.3.4.11.2) give insight into structural preferences of both enzymes.
为了优化亮氨酸氨肽酶[EC3.4.11.1] S1口袋中潜在抑制剂的侧链形状,进行了一系列结构上不同的α-氨基烷基膦酸酯的合成和生物学活性研究。对具有芳香族,脂肪族和脂环族P1侧链的一系列化合物进行分析,可以找出最适合LAP抑制剂片段的结构特征。在所有研究的化合物中,最活跃的化合物是高酪氨酸(K(i)= 120 nM)和高苯丙氨酸(K(i)= 140 nM)的膦酸酯类似物,与外消旋混合物相比,即使是外消旋混合物也是更好的抑制剂迄今为止最好的磷酸左旋亮氨酸类似物(230 nM)。对氨基肽酶N(APN,EC3.4.11。
