Epitalon is a synthetic tetrapeptide, meaning it is made up of four amino acids, the basic building blocks of proteins

The TP receptor antagonist (SQ29548) inhibits both cyclooxygenase (COX)-2 expression and FLS proliferation, and TP agonist U46619 enhances them

In the same context, AGEs have been also shown to quench NO and at the same time induce endothelin-1 (a powerful vasoconstrictor), further tipping the scales in favor of vasoconstriction ( in vitro experiments support that PS-exposing RBCs can be targeted by secretory phospholipase A 2 , releasing lysophosphatidic acid, a potent lipid mediator that can induce endothelial dysfunction and even vascular leak (Neidlinger et al., 2006)
