摘要

To identify new orally active inhibitors, further modification of 1 (ONO-6818) was performed. Peptidic derivatives 4b, 4c and 4n showed more potent inhibitory activity than nonpeptidic derivatives 3a–c. As a result, a series of peptidic inhibitors, 4a–s and 5a–v, were discovered. Among these N-aryl derivatives 5a–g, 5i, 5m and 5o–v showed oral activity. Their oral activity showed good correlation with their metabolic stability. Compounds 5h and 5j–l, ...
