AF-353 is a P2X3 receptor antagonist. Antagonism of the P2X3 receptor is one of the potential therapeutic strategies for the management of neuropathic pain because P2X3 receptors are predominantly localized on small to medium diameter C- and Aδ-fiber primary afferent neurons, which are related to the pain-sensing system.

AF-353 (Ro-4) is a highly potent inhibitor of α,β-meATP-evoked intracellular calcium flux in cell lines expressing recombinant rat and human P2X3 and human P2X2/3 channels.
AF-353 (Ro-4) also blocks human P2X2/3 channel function with marginally reduced potency with a p50 of 7.3.
AF-353 (Ro-4) does not compromise oxygen levels or cardiac function.
AF-353 (Ro-4) (10 mg/kg, 20 mg/kg; i.v.; for 4-6 hours) inhibits the purinergic response in both normal and spinal cord-injured (SCI) rats.
AF-353 (Ro-4) (10 mg/kg, 20 mg/kg; i.v.; for 4-6 hours) also reduces the inter-contractile interval in normal but not in SCI rats; however, the frequency of non-voiding (NVC) in SCI rats is significantly reduced.
