MedKoo CAT#: 530558

CAS#: 4499-01-8 (sodium)

Description: PSB-1011 is a competitive inhibitor of the rat P2X2 receptor with a Ki value of 79 nM. PSB-1011 exhibited a competitive mechanism of action (pA(2) 7.49). It was >100-fold selective versus P2X4, P2X7, and several investigated P2Y receptor subtypes (P2Y(2,4,6,12)); selectivity versus P2X1 and P2X3 receptors was moderate (>5-fold). PSB-1011 was >13-fold more potent at the homomeric P2X2 than at the heteromeric P2X2/3 receptor.
