title: 1-Oxacephem-based human chymase inhibitors: discovery of stable inhibitors in human plasma.
abstract: 1-Oxacephem derivatives were evaluated as a novel series of chymase inhibitors. The structure-activity relationship studies of 1-oxacephems led to compounds 15, which exhibited 27 nM inhibition of human chymase and improvement of stability in human plasma (t 1/2 1.5 h).
