Histone lysine specific demethylase 1 (LSD1) is overexpressed in diverse hematologic disorders and recognized as a promising target for blood medicines. In this study, molecular docking-based virtual screening united with bioevaluation was utilized to identify novel skeleton of 5-arylidene barbiturate as small-molecule inhibitors of LSD1. Among the synthesized derivatives, 12a exhibited reversible and
组蛋白赖氨酸特异性脱甲基酶1(LSD1)在各种血液系统疾病中过表达,被公认为是血液药物的有希望的靶标。在这项研究中,结合生物评估的基于分子对接的虚拟筛选被用来鉴定5-芳基巴比妥酸酯的新骨架作为LSD1的小分子抑制剂。在合成的衍生物中,12a 对MAO-A和MAO-B表现出可逆和有效的抑制作用(IC 50 = 0.41μM)和高选择性。值得注意的是,12a强烈诱导了对急性早幼粒细胞白血病NB4细胞系的分化作用,并明显提高了组蛋白3赖氨酸4(H3K4)的甲基化水平。我们的研究结果表明5-芳基巴比妥酸酯可能代表了LSD1抑制剂的新骨架和12a应该作为进一步研究的有希望的媒介。
