Pharmacological inhibition of P2RX4 receptor as a potential therapeutic strategy to prevent intracranial aneurysm formation.
(PubMed, Exp Neurol)
- "Consistently, the selective P2RX4 antagonist NC-2600, which potently inhibited Ca2+ influx in response to shear-stress loading in endothelial cells in vitro, significantly suppressed the formation of IAs. The results of the present study contribute to our understanding of the pathogenesis of IAs and may provide benefits to society through the future development of medical therapies targeting P2RX4."

P2X4 receptor mediates macrophage infiltration leading to endometriotic cyst epithelium proliferation and hyperalgesia in mouse model.
(PubMed, F S Sci)
- "These results indicate unknown pathophysiological roles of P2X4R expressed in local macrophages at the injury site of endometriosis and in the vagina, suggesting the potential therapeutic effects of orally administered P2X4R inhibitors for alleviating the symptoms of endometriosis."

The pharmacological blockade of P2X4 receptor as a viable approach to manage visceral pain in a rat model of colitis.
(PubMed, J Drug Target)
- "Herein, we tested the pain-relieving effect of two novel and selective P2X4R antagonists (NC-2600 and NP-1815-PX) in a murine model of DNBS-induced colitis and investigated the mechanisms underlying their effect. Tested drugs and dexamethasone (DEX) were administered orally, two days after colitis induction...By contrast, CaCo2 cells treated with supernatant from THP-1 cells, previously incubated with tested drugs, counteracted the reduction of tight junctions due to the inhibition of P2X4R/NLRP3/IL-1β axis. In conclusion, these results suggest that the direct and selective inhibition of P2X4R represents a viable approach for the management of visceral pain associated with colitis via NLRP3/IL-1β axis inhibition."

ANTI-INFLAMMATORY EFFECTS OF NOVEL P2X4 RECEPTOR ANTAGONISTS, NC-2600 AND NP-1815-PX, IN A MURINE MODEL OF COLITIS
(DDW 2022)
- "Methods : Test drugs [NC-2600, NP-1815-PX and dexamethasone (DEX)] were administered orally for 6 days, immediately after the delivery of DNBS. This effect was inhibited upon incubation with NC-2600 and NP-1815-PX. Conclusion s: These findings demonstrated for the first time that the direct and selective inhibition of P2X4 receptors represent a viable approach for the management of bowel inflammation via the inhibition of the canonical and non-canonical NLRP3 inflammasome signaling pathways."

Anti-inflammatory Effects of Novel P2X4 Receptor Antagonists, NC-2600 and NP-1815-PX, in a Murine Model of Colitis.
(PubMed, Inflammation)
- "These two drugs and dexamethasone (DEX) were administered orally for 6 days, immediately after the manifestation of DNBS. In THP-1 cells, lipopolysaccharide and ATP upregulated IL-1β release and NLRP3, caspase-1, caspase-5, and caspase-8 activity, but not of caspase-4. These changes were prevented by NC-2600 and NP-1815-PX treatment. For the first time, the above findings show that the selective inhibition of P2X4 receptors represents a viable approach to manage bowel inflammation via the inhibition of NLRP3 inflammasome signaling pathways."

- "Although several P2X3R antagonists have been developed, we believe P2X4R is ideal target for chronic cough and NC-2600 will be effective for wider range of chronic cough than targeting P2X3. Its Ph-1 is completed in Japan, and no taste disturbances were observed, which is one of concerns of P2X3R antagonists."

Nociceptive signaling of P2X receptors in chronic pain states.
(PubMed, Purinergic Signal)
- "The phase I study of NC-2600 has been completed, and no serious side effects were reported. The roles played by purinergic receptors in evoking neuropathic pain provide crucial insights into the pathogenesis of neuropathic pain."
