Type I collagen, type V collagen, chymase, β-myosin heavy chain, and A-Raf differential expression were consistent in western blotting. In conclusion, salvianolate had a protective effect on myocardial tissues of rats with myocardial infarction. Several proteins including type I collagen, type V collagen, chymase, β-myosin, and A-Raf may be salvianolate targets for treatment of myocardial infarction.The unfolded protein response (UPR) is an emerging target pathway for cancer treatment owing to its ability to induce cell death. In our previous analysis of UPR-modulating small molecules, we had reported that piperazine oxalate derivative compounds (AMC-01-04) are able to promote increased phosphorylation of eukaryotic translation initiation factor-2 alpha (eIF2α). In this study, we found that AMC-04 induces apoptotic cell death via the activation of UPR in human breast and liver cancer cells. AMC-04 upregulated the expression of activating transcription factor-4 (ATF4)-C/EBP homologous protein (CHOP) and death receptor 5 (DR5) in cancer cells, as revealed by microarray analysis, small-interference RNA assay, and western blotting. From a mechanistic perspective, cytotoxic UPR pathway activation by AMC-04 is mediated by reactive oxygen species (ROS) and p38 mitogen-activated protein kinase (p38 MAPK) signaling. A chemical informatics approach predicted that AMC-04 modulates histone methyltransferase activity. Based on biochemical analysis, the activity of histone methyltransferases, including SUV39H1, SUV39H2, SETDB1, and EHMT1, was inhibited by AMC-04. Furthermore, chemical inhibition of the identified target proteins induced UPR activation
