ARL67156 (FPL 67156) trisodium hydrate is a selective ecto-ATPase inhibitor. ARL67156 trisodium hydrate is a competitive inhibitor of NTPDase1 (CD39), NTPDase3 and NPP1, with Kis of 11, 18 and 12 μM, respectively. ARL67156 trisodium hydrate can be used in the research of disease like calcific aortic valve disease, asthma[1][2].
ARL67156 trisodium hydrate (1-100 μM) potentiates neurogenic contractions in a concentration-dependent manner[4].ARL67156 trisodium hydrate (10 μg/mL, 24 h) increases the surface expression of CXCR3 on ATP-treated HMC-1 cells[5].ARL67156 trisodium hydrate (30 μM, 5s) potentiates the norepinephrine release promoted by ATP in guinea pig heart synaptosomes[6].ARL67156 trisodium hydrate (100 μM, 4h) significantly decreases HIV-1replication in macrophages[7].
ARL67156 trisodium hydrate (1.1 μg/kg/day, administered with osmotic pumps implanted subcutaneously, for 28 days) prevents the development of calcific aortic valve disease in Warfarin -treated rats[2].ARL67156 trisodium hydrate (intraperitoneal injection, 2 mg/kg) prevents the increase of serum adenosine concentration induced by Fructose 1,6-bisphosphate (FBP)[3].
