NP-1815-PX sodium

Customer Review

Based on 1 Customer Validation

NP-1815-PX sodium is an orally active dual inhibitor of P2X4 and prostaglandin TP receptors, with an IC₅₀ of 0.26 μM against human P2X4 receptors. NP-1815-PX sodium specifically inhibits ATP-mediated prostaglandin production, TP receptor-induced calcium elevation, and the canonical/non-canonical NLRP3 inflammasome signaling pathway. NP-1815-PX sodium selectively blocks smooth muscle contractions induced by ATP, U46619 (HY-108566) and prostaglandin F2α. NP-1815-PX sodium not only produces anti-allodynic effects in vivo, but also significantly alleviates symptoms of DNBS (HY-W324435)-induced colitis (such as weight loss and tissue damage). NP-1815-PX sodium exerts anti-inflammatory effects by downregulating IL-1β levels and Caspase-1 activity. NP-1815-PX sodium is used in studies related to asthma and inflammatory bowel disease (colitis).

In Vitro

NP-1815-PX (10^-5 M; 30 min) strongly suppresses ATP-induced contractions in guinea pig epithelium-intact tracheal smooth muscle^[1].
NP-1815-PX (10^-5-10^-4 M; 60 min) inhibits U46619-induced contractions in a concentration-dependent manner in guinea pig epithelium-denuded tracheal smooth muscle, with an apparent pA₂ value of 4.59^[1].
NP-1815-PX (10^-5-10^-4 M; 60 min) inhibits PGF₂α-induced contractions in a concentration-dependent manner in guinea pig epithelium-denuded tracheal smooth muscle^[1].
NP-1815-PX (10^-4 M; 60 min) does not substantially inhibit contractions induced by carbachol, histamine, neurokinin A, or 50 mM KCl in guinea pig epithelium-denuded tracheal smooth muscle^[1].
NP-1815-PX (10^-5-10^-4 M; 60 min) inhibits U46619-induced contractions in a concentration-dependent manner in guinea pig epithelium-denuded bronchial smooth muscle^[1].
NP-1815-PX (10^-5-10^-4 M; 10 min) inhibits TP receptor-expressing 293T cells-induced intracellular Ca²⁺ increases in a concentration-dependent manner in human TP receptor-expressing 293T cells^[1].
NP-1815-PX (0.1-10 μM; 1 h pre-incubation) modulates canonical and non-canonical NLRP3 inflammasome pathways in human monocytic THP-1 cells, with 10 μM significantly reducing LPS/ATP-induced NLRP3, cleaved caspase-1, caspase-5, and caspase-8 expression, as well as IL-1β release^[2].

Western Blot Analysis^[2]

Cell Line:

Human monocytic THP-1 cells
Concentration:

10 µM
Incubation Time:

1 h pre-incubation
Result:

Significantly reduced the levels of LPS/ATP-induced NLRP3, cleaved caspase-1, caspase-5, and caspase-8 expression, as well as IL-1β release in human monocytic THP-1 cells.

In Vivo

NP-1815-PX (3-30 mg/kg; p.o.; daily; 6 days) sodium significantly attenuates DNBS (HY-W324435)-induced body weight loss, spleen weight increase, and macroscopic colonic injury in rats, with the 10 mg/kg dose additionally significantly reducing colonic caspase-1 activity and restoring occludin expression, while none of the doses significantly reduce microscopic colonic damage or DNBS-induced colonic IL-1β increases^[2].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
