MRS 2365

MRS2365 is a potent and selective P2Y1 receptor (EC50=0.4 nM) /[35S]GTPγS binding/β-arrestin 2 recruitment agonist with an EC50 of 0.4 nM. MRS2365 relieves mechanical allodynia and increases mechanical sensitivity. MRS2365 shows little agonist or antagonist activity at the P2Y12 or P2Y13 receptors[1][2][3][4].

Highly potent, selective P2Y 1 receptor agonist (EC 50 = 0.4 nM). Displays no activity at P2Y 12 receptors and only very low agonist activity at P2Y 13 receptors (at concentrations up to 1 μ M).

P2Y1 Receptor: 0.4 nM (EC₅₀)
