Full details of the concise and convergent synthesis (eight steps, 19% overall yield), its extension to the preparation of a series of key analogues, and the molecular target and pharmacophore of largazole are described. Central to the synthesis of largazole is a macrocyclization reaction for formation of the strained 16-membered depsipeptide core followed by an olefin cross-metathesis reaction for
描述了简洁和收敛的合成(八个步骤,总产率为 19%)的全部细节,其扩展到一系列关键类似物的制备,以及拉格唑的分子靶点和药效团。拉格唑合成的核心是形成紧张的 16 元缩酚肽核心的大环化反应,然后是用于安装硫酯的烯烃交叉复分解反应。拉格唑及其关键类似物的生物学评价,包括乙酰类似物、硫醇类似物和羟基类似物,表明组蛋白脱乙酰酶 (HDAC) 是拉格唑的分子靶点,拉格唑是 I 类 HDAC 抑制剂。此外,构效关系 (SAR) 研究表明,硫醇基团是天然产物的药效团。拉格唑'
