2-MeSADP

2-MeSADP (2-Methylthioadenosine diphosphate; 2-Methylthio-ADP) is a potent purinergic P2Y receptors agonist, with EC50s of 19, 6.2, and 5 nM for human P2Y13, mouse P2Y13 and human P2Y12, respectively. 2-MeSADP has pEC50s of 8.29 and 5.75 for human P2Y1 and rat P2Y6, respectively. 2-MeSADP induces platelet aggregation and shape change, and inhibits cyclic AMP accumulation in platelets exposed to prostaglandin E1[3].
