Piromelatine (Neu-P11) is a melatonin MT1/MT2 receptor agonist, serotonin 5-HT1A/5-HT1D agonist, and serotonin 5-HT2B antagonist. Piromelatine (Neu-P11) possesses sleep promoting, analgesic, anti-neurodegenerative, anxiolytic and antidepressant potentials. Piromelatine (Neu-P11) also possesses pain-related P2X3, TRPV1, and Nav1.7 channel-inhibition capacities[1][2][3].
