MedChemExpress -Model Sodium metatungstate -12141-67-2

FromMedChemExpress LLC (MCE)

Sodium metatungstate (Sodium polyoxotungstate) is a NTPDase inhibitor, with Ki values of 2.58 μM, 3.26 μM, and 28.8 μM for NTPDase 1 (CD39), NTPDase 3 and NTPDase 2 respectively[1]. Sodium metatungstate has anti-inflammatory and anti-cancer effect. Sodium metatungstate inhibits ATP breakdown but also blocks central synaptic transmission[1][2][3][4].

Description：Sodium metatungstate (Sodium polyoxotungstate) is a NTPDase inhibitor, with Ki values of 2.58 μM, 3.26 μM, and 28.8 μM for NTPDase 1 (CD39), NTPDase 3 and NTPDase 2 respectively. Sodium metatungstate has anti-inflammatory and anti-cancer effect. Sodium metatungstate inhibits ATP breakdown but also blocks central synaptic transmission.

In Vitro：Sodium metatungstate (100 μM, 15 min) inhibits the ATP-induced uptake of anionic dyes and the large ATP-induced channels in macrophage[2]. Sodium metatungstate (100 μM, 8 h) inhibits ATP-induced P2X7-associated pyroptosis in macrophage[2]. Sodium metatungstate (100 μM, 8-24 h) has a potent anti-inflammatory effect on macrophages[2].

In Vivo：Sodium metatungstate (5 mg/kg, Intraperitoneal injection, single dose) shows different cytokine/chemokine responses in the peritoneum and systemically in the bloodstream in CD39 knockout mice[3]. Sodium metatungstate (5 mg/kg, Intraperitoneal injection, once per day from 0 to day 4, day 7-11, and day 14-18.) combine with anti-CD73 antibody and AZD4635(HY-101980) reduces tumor load in multiple myeloma (MM) mice[4].

IC50 & Target：IL-1β P2X7 Receptor
