first clinical candidate, Boceprevir (SCH 503034), we approached the depeptidization of the molecule through macrocyclization. Herein we report the design and synthesis of fluoro amino acids with desired stereochemistry required for the synthesis of macrocyclic inhibitors with fluorine at various positions of the aliphatic chain. Biological activities of representative examples are also reported.
丙型肝炎病毒(HCV)是一种主要的健康危害,其感染是全世界慢性肝病的主要原因。在努力寻找支持我们的第一个临床候选药物Boceprevir(SCH 503034)的过程中,我们通过大环化方法对分子进行了去肽化处理。在本文中,我们报道了具有在脂肪族链的各个位置上具有氟的大环抑制剂的合成所需的具有所需立体化学的氟氨基酸的设计和合成。还报道了代表性实例的生物活性。
