Abstract

Monascustin (1), an unusual γ-lactam, was isolated from an ethanol extract of the Monascus purpureus fermented rice. Its structure including the absolute configuration was determined by spectroscopic data analysis and confirmed by X-ray crystallography. A plausible biosynthetic pathway is discussed on the basis of amino acid derivatization. Compound 1 showed inhibitory activity against histone deacetylase 1.

摘要

红曲菌素（1）是一种不寻常的γ-内酰胺，从紫红曲霉发酵大米的乙醇提取物中分离得到。通过光谱数据分析确定了其结构，包括绝对构型，并通过X射线晶体学得到证实。基于氨基酸衍生化讨论了一种可能的生物合成途径。化合物1对组蛋白去乙酰化酶1显示出抑制活性。
