4-tetrahydronaphthyl)acetyl]-L- thioprolyl]thiazolidine (13) exhibited an approximately 20-fold (IC50 = 2.3 nm) increase in potency compared with 1. Compounds having a formyl or a cyano group showed much more potent inhibitory activities than those which lack such a functional group. Among all compounds tested in vitro, 1-[1-(2-indanylacetyl)-L-prolyl]prolinal (27), 1-[1-[(S)-2-(1,2,3,4-tetrahydronaphthyl)acetyl]-L-
通过对1- [1-(4-苯基丁酰基)-L-脯氨酰基]-吡咯烷(SUAM-1221,1)或1- [1-(苄氧羰基)-L-脯氨酸]脯氨酸(Z- Pro-proalal,2)和被测试对犬脑中纯化的脯氨酰内肽酶(PEP)的体外抑制活性。在一系列缺少甲酰基或氰基的化合物中,3- [3-[(S)-2-(1,2,3,4-四氢萘基)乙酰基] -L-硫代脯氨酰基]噻唑烷(13)与1相比,效价提高了约20倍(IC50 = 2.3 nm)。具有甲酰基或氰基的化合物显示出比没有这种官能团的化合物更有效的抑制活性。在体外测试的所有化合物中,1- [1-(2-茚满基乙酰基)-L-脯氨酰基]脯氨酸(27),1- [1-[(S)-2-(1,2,3,4-四氢萘基)乙酰基] -L-脯氨酰]脯氨酸(29),1- [3-[(S)-2-(1,2,3,
