在我们在花生上培养产黄曲霉毒素的实验中,我们意外地发现粘附在花生上的一种细菌强烈抑制黄曲霉产生黄曲霉毒素(AF)。该细菌被分离并鉴定为产气克雷伯氏菌,被发现能产生 AF 生成抑制剂。从细菌培养上清液中分离得到的环(L-Ala-Gly)是主要活性成分。环(L-Ala-Gly)的黄曲霉毒素产生抑制活性尚未见报道。 Cyclo(l-Ala-Gly) 抑制黄曲霉中 AF 的产生,而不影响其在液体培养基中的真菌生长,其效力比环(l-Ala-l-Pro) 更强。在已知的抑制 AF 产生的二酮哌嗪类化合物中,Cyclo(l-Ala-Gly) 具有最强的 AF 产生抑制活性。环(1-Ala-Gly)中的甲基部分被乙基、丙基或异丙基取代的相关化合物显示出比环(1-Ala-Gly)强得多的活性。与 (l-Ala-l-Pro) 不同,Cyclo(l-Ala-Gly) 不会抑制黄曲霉中的重组谷胱甘肽-S-转移酶

The present invention relates to peptidomimetic compounds useful as protease inhibitors, particularly as serine protease inhibitors and more particularly as hepatitis C NS3 protease inhibitors; intermediates thereto; their preparation including novel steroselective processes to intermediates. The invention is also directed to pharmaceutical compositions and to methods for using the compounds for inhibiting HCV protease or treating a patient suffering from an HCV infection or physiological condition related to the infection. Also provided are pharmaceutical combinations comprising, in addition to one or more HCV serine protease inhibitors, one or more interferons exhibiting anti-HCV activity and/or one or more compounds having anti HCV activity and a pharmaceutically acceptable carrier, and methods for treating or preventing a HCV infection in a patient using the compositions. The present invention is also directed to a kit or pharmaceutical pack for treating or preventing HCV infection in a patient.
