Opiranserin (VVZ-149), a non-opioid and non-NSAID analgesic candidate, is a dual antagonist of glycine transporter type 2 (GlyT2) and serotonin receptor 2A (5HT2A), with IC50s of 0.86 and 1.3 μM, respectively. Opiranserin shows antagonistic activity on rP2X3 (IC50=0.87 μM). Opiranserin is development as an injectable agent for the treatment of postoperative pain[1][2][3].

GlyT2: 0.86 μM (IC₅₀); P2X3 Receptor; rP2X3: 0.87 μM (IC₅₀); 5-HT_2A Receptor: 1.3 μM (IC₅₀)
