To identify cell-active sirtuin inhibitors containing N-thioacetyl lysine, we synthesized compound 1, which was designed based on the structure of the reported N-ethoxycarbonylacetyl lysine-based sirtuin inhibitor NCS-12k. Compound 1 selectively inhibited SIRT1 in enzyme assays. Compound 1 also caused a dose-dependent increase in p53 acetylation in human colon cancer HCT116 cells, indicating the inhibition of SIRT1 in these cells.
为了鉴定含N-硫代乙酰赖氨酸的细胞活性沉默调节蛋白抑制剂，我们合成了化合物1，它是基于已报道的基于N-乙氧羰基乙酰赖氨酸的沉默调节蛋白抑制剂NCS-12k的结构设计的。在酶分析中，化合物1选择性地抑制SIRT1。化合物1还导致人结肠癌HCT116细胞中p53乙酰化呈剂量依赖性增加，表明在这些细胞中SIRT1受到抑制。
