Benzoxazoles 166-177 elastase, neutrophil expressed Homo sapiens 24-27 7837243-4 1995 Several heterocycles, including oxazoline and benzoxazole, afforded extremely potent inhibitors of HNE (1p-r) with nanomolar to subnanomolar Ki values. Benzoxazoles 46-57 elastase, neutrophil expressed Homo sapiens 99-102
