Amplification of HSF1 transcriptional activity in human HeLa cells assessed as HFS1 granule count at 80 uM by immunocytochemical staining - BioAssay Summary
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 (EC(50)=2.5microM) and significant cytoprotection in both rotenone (EC(50)=0.23microM) and oxygen-glucose deprivation cell toxicity models (80% protection at 2.5microM). ..more

Title: Pyrimido[5,4-e][1,2,4]triazine-5,7(1H,6H)-dione derivatives as novel small molecule chaperone amplifiers.
