Omuralide, a transformation product of the microbial metabolite lactacystin, was the first molecule discovered as a specific inhibitor of the proteasome and is unique in that it specifically inhibits the proteolytic activity of the 20S subunit of the proteasome without inhibiting any other protease activities of the cell. The total syntheses of omuralide and (+)-lactacystin are reported. An important
Omuralide 是微生物代谢产物乳胞素的转化产物,是第一个被发现作为蛋白酶体特异性抑制剂的分子,其独特之处在于它特异性抑制蛋白酶体 20S 亚基的蛋白水解活性而不抑制细胞的任何其他蛋白酶活性. 报告了 omuralide 和 (+)-lactacystin 的全合成。在早期合成了一个重要的关键中间体,这使得这两种天然产物的类似物很容易制备。
