  Inhibition of norovirus 3CL protease by bisulfite adducts of transition state inhibitors

  摘要：

  Noroviruses are the most common cause of acute viral gastroenteritis, accounting for >21 million cases annually in the US alone. Norovirus infections constitute an important health problem for which there are no specific antiviral therapeutics or vaccines. In this study, a series of bisulfite adducts derived from representative transition state inhibitors (dipeptidyl aldehydes and alpha-ketoamides) was synthesized and shown to exhibit anti-norovirus activity in a cell-based replicon system. The ED50 of the most effective inhibitor was 60 nM. This study demonstrates for the first time the utilization of bisulfite adducts of transition state inhibitors in the inhibition of norovirus 3C-like protease in vitro and in a cell-based replicon system. The approach described herein can be extended to the synthesis of the bisulfite adducts of other classes of transition state inhibitors of serine and cysteine proteases, such as alpha-ketoheterocycles and alpha-ketoesters.

  hydroxylamines, followed by N-protection, and oxidative cleavage of the carboxyl precursor gave a range of N-protected amino acids and esters. The method was exemplified by the synthesis of a range of derivatives of non-proteinogenic amino acids such as 4-bromophenylalanine, tert-leucine, norvaline, cyclohexyl- and aryl-glycines, 2-amino-8-oxodecanoic acid (Aoda) and alpha-methylvaline.

  描述了一种新的α-氨基酸的不对称合成方法，其中关键步骤是将有机锂羧基合成子（2-呋喃基锂，苯基锂，乙烯基锂）高度非对映选择性地添加到（R）-和（S）-O-（1-苯基丁基） ）肟产生羟胺，乙烯基锂是最令人满意的亲核试剂。随后还原羟胺中的NO键，然后进行N-保护，然后对羧基前体进行氧化裂解，得到一系列N-保护的氨基酸和酯。通过合成一系列非蛋白质氨基酸的衍生物（例如4-溴苯丙氨酸，叔亮氨酸，正缬氨酸，环己基和芳基甘氨酸，2-氨基-8-氧代十二烷酸（Aoda）和α）来举例说明该方法。 -甲基缬氨酸。

  CPL-catalysed resolution. The mechanism of the CPL-catalysed enantioselective alcoholoysis of the amino acids is discussed to delineate the substrate requirements for CPL-catalysed resolution. Finally, the reaction was scaled up, and the products were separated and obtained in good yields (≥ 80 %). The (S)-3-amino-3-phenylpropanoic acid obtained was used as a key chiral intermediate in the synthesis
