Pyrimido[5,4-e][1,2,4]triazine-5,7(1H,6H)-dione derivatives were investigated as novel small molecule amplifiers of heat shock factor 1 transcriptional activity. Lead optimization led to the discovery of compound 4A-13, which displayed potent HSF1 activity under mild heat stress (EC50 = 2.5 μM) and significant cytoprotection in both rotenone (EC50 = 0.23 μM) and oxygen-glucose deprivation cell toxicity
嘧啶[5,4- e ] [1,2,4]三嗪-5,7(1 H,6 H)-二酮衍生物被研究为热休克因子1转录活性的新型小分子放大器。铅的优化导致化合物4A-13的发现,该化合物在轻度热应激下(EC 50 = 2.5μM)表现出强大的HSF1活性,在鱼藤酮(EC 50 = 0.23μM)和氧-葡萄糖剥夺细胞毒性模型中均具有显着的细胞保护作用(在2.5μM时具有80%的保护)。
