in peptide vinyl sulfone and peptide epoxy ketone-based proteasome inhibitors. Pyridin-2-ones have previously been used as constrained peptide isosteres capable to act as a hydrogen-bond acceptor. Our results demonstrate that 5-methylpyridin-2-one can be introduced into proteasome inhibitors, but that the activity of the resulting compounds is compromised compared to their parent peptide vinyl sulfones
人类蛋白酶体是肿瘤学中经过验证的靶标,并且是免疫相关疾病的有希望的靶标。许多基于肽的蛋白酶体抑制剂已进入临床,其他几种目前正在临床试验中进行研究。尽管取得了这些成就,但基于肽的抑制剂可能容易受到蛋白酶介导的降解。在本文中,我们报告了在肽乙烯基砜和基于肽环氧酮的蛋白酶体抑制剂中引入 5-methylpyridin-2-one 部分的结果。Pyridin-2-ones 以前曾被用作能够作为氢键受体的受限肽等排体。我们的结果表明 5-methylpyridin-2-one 可以被引入蛋白酶体抑制剂中,
