is associated with the tumor angiogenesis and metastasis. In this report, one new series of leucine ureido derivatives containing the triazole moiety was designed, synthesized and evaluated as APN inhibitors. Among them, compound 13v showed the best APN inhibition with an IC50 value of 0.089 ± 0.007 μM, which was two orders of magnitude lower than that of bestatin (IC50 = 9.4 ± 0.5 μM). Compound 13v
氨基肽酶N在各种恶性细胞上的过表达与肿瘤血管生成和转移有关。在该报告中,设计,合成并评估了一系列新的含有三唑部分的亮氨酸脲基衍生物,并将其评估为APN抑制剂。其中,化合物13v表现出最佳的APN抑制作用,IC50值为0.089±0.007μM,比Bestatin的IC50值低两个数量级(IC50 = 9.4±0.5μM)。化合物13v还显示出剂量依赖性的抗血管生成活性。即使在较低浓度(10μM)下,化合物13v在人脐静脉内皮细胞(HUVEC)毛细血管形成试验和大鼠胸主动脉环试验中也显示出与100μM的Bestatin相似的抗血管生成活性。此外,与Bestatin相比,13v表现出可比性,
