Overexpression of lysine specific demethylase 1 (LSD1) has been found in many cancers. New anticancer drugs targeting LSD1 have been designed. The research on irreversible LSD1 inhibitors has entered the clinical stage, while the research on reversible LSD1 inhibitors has progressed slowly so far. In this study, 41 stilbene derivatives were studied as reversible inhibitors by three-dimensional quantitative structure–activity
在许多癌症中都发现了赖氨酸特异性脱甲基酶 1 (LSD1) 的过度表达。已经设计出针对 LSD1 的新型抗癌药物。不可逆LSD1抑制剂的研究已进入临床阶段,而可逆LSD1抑制剂的研究至今进展缓慢。在这项研究中,通过三维定量构效关系 (3D-QSAR) 研究了 41 种二苯乙烯衍生物作为可逆抑制剂。比较分子场分析(CoMFA q2 = 0.623, r2 = 0.987, rpred2 = 0.857)和比较分子相似性指数分析(CoMSIA q2 = 0.728, r2 = 0.960, rpred2 = 0.899)用于建立模型,结构-活性等高线图解释了化合物的关系。结合位点由两种不同的软件预测,并进一步探索了化合物的结合模式。发现一系列关键氨基酸 Val288、Ser289、Gly314、Thr624、Lys661 在化合物的活性中起关键作用。对具有不同活性的化合物 04、17、21 和
