indicated that compounds 4e and 4m were reversible LSD1 inhibitors. High content analysis showed that 4e and 4m induced a dose-dependent increase of dimethylated Lys4 of histone H3 and had no impact on the expression of LSD1 in MGC-803 cells. Furthermore, 4e or 4m could remarkably increase the mRNA level of CD86, a surrogate cellular biomarker for LSD1 activity, in MGC-803 cells, suggesting that they
最近,赖氨酸特异性脱甲基酶1(LSD1)的抑制作用已成为治疗癌症和其他疾病的有吸引力的治疗靶标。作为我们不断努力寻找新型小分子LSD1抑制剂的连续性,我们设计并合成了一系列白藜芦醇衍生物,它们被证明是LSD1的有效抑制剂。其中,化合物4e和4m在酶分析中显示出最有效的LSD1抑制活性,IC 50值分别为121 nM和123 nM。生化研究和对接分析表明,化合物4e和4m是可逆的LSD1抑制剂。高含量分析表明4e和4m诱导组蛋白H3的二甲基化Lys4的剂量依赖性增加,并且对MGC-803细胞中LSD1的表达没有影响。此外,4e或4m可以显着增加MGC-803细胞中CD86的LSD1活性的替代生物标志物CD86的mRNA水平,表明它们很可能在细胞内表现出LSD1抑制活性。这些发现应鼓励进一步修饰这些化合物,以产生具有潜在抗癌活性的更有效的LSD1抑制剂。
