inhibition. However, para- and some meta-substitutions of the terminal phenyl ring enhanced inhibitory activity and led to improve metabolic stability. This agrees with the result from metabolism studies with compound 1 that the primary route of biotransformation is oxidation, mainly at the para position of the phenyl ring and the α position of the sulfonyl group in the aliphatic side chain.

环丙烷和苯氧基苯基的存在对于明胶酶抑制很重要。然而,末端苯环的对位和一些间位取代增强了抑制活性并导致改善代谢稳定性。这与化合物1 的代谢研究结果一致
生物转化的主要途径是氧化,主要在苯环的对位和脂肪族侧链中磺酰基的α位。
