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
