activity and oral activity in an acute hemorrhagic assay have been explored. These compounds contained either a trifluoromethyl ketone or a boronic acid moiety to bind covalently to the Ser-195 hydroxyl of human leukocyte elastase (HLE). Boronic acid-containing inhibitors were found to be more potent than the corresponding trifluoromethyl ketones in vitro but were less active upon oral administration
已经探索了一系列5-氨基-2-嘧啶-6-酮的取代变化对急性出血试验中体外活性和口服活性的影响。这些化合物包含三氟甲基酮或硼酸部分,以与人白细胞弹性蛋白酶(HLE)的Ser-195羟基共价结合。发现含硼酸的抑制剂在体外比相应的三氟甲基酮更有效,但是口服给药时活性较低。发现化合物13b提供了口服效力,作用持续时间和酶选择性的最佳组合,因此,选择了其用于进一步的生物学测试。
