The present invention provides a group of novel compounds that inhibit the proteolytic activity of 3C proteases which are found in picornaviruses, particularly rhinoviruses. In picornaviruses the RNA genome is translated into a single large viral polyprotein precursor. The precursor demonstrates auto-proteolytic activity, cleaving itself into mature viral gene products. Therefore, compounds of the current invention are particularly useful in treating picornaviral infections by interrupting the processing of the viral gene products into mature and infectious viral particles. The current invention also provides a novel process the preparation of compounds of the current invention. The process entails the selective reduction of an imide intermediate representing a marked improvement over processes known in the art for making peptidyl-aldehydes.
本发明提供了一组新颖的化合物,可以抑制在小RNA病毒中发现的3C蛋白酶的蛋白水解活性,特别是鼻病毒。在小RNA病毒中,RNA基因组被翻译成一个单一的大型病毒多肽前体。该前体表现出自体蛋白水解活性,将自身切割成成熟的病毒基因产物。因此,本发明的化合物特别适用于通过干扰病毒基因产物的加工过程,使其成熟并具有传染性的病毒颗粒,从而治疗小RNA病毒感染。本发明还提供了一种制备本发明化合物的新方法。该方法包括选择性还原代表对于制备肽醛已知技术的显著改进的酰胺中间体。
