S3217 Brilliant Blue G

Brilliant Blue G (BBG) is a potent non-competitive antagonist of P2X7 receptor with IC50 of 10.1 nM and 265 nM for rat P2X7 and human P2X7, respectively. Brilliant Blue G is a dye which is commonly used in laboratories to stain or quantify proteins.

Selective human P2X7, IC50: 265 nM; rat P2X7, IC50: 10.1 nM
S3293 Gardenoside

Gardenoside is a natural compound extracted from Gardenia fruits, with hepatoprotective properties. Gardenoside inhibits TNF-α, IL-1β, IL-6 and NFκB activation. Gardenoside also has an inhibitory effect on free fatty acids (FFA)-induced cellular steatosis. Gardenoside suppresses the pain in rats model of chronic constriction injury by regulating the P2X3 and P2X7 receptors.

S3766 Tanshinone IIA sulfonate sodium

Sodium tanshinone IIA sulfonate (STS) is a water-soluble derivative of tanshinone IIA isolated as the main pharmacologically active natural compound from a traditional Chinese herbal medicine, the dried root of Salvia miltiorrhiza Bunge known as Danshen. Sodium tanshinone IIA sulfonate (STS) is a potent negative allosteric modulator of the human purinergic receptor P2X7. Sodium tanshinone IIA sulfonate (STS) inhibits the activity of CYP3A4 and store-operated Ca2+ entry (SOCE)

S6664 Gefapixant

Gefapixant (AF-219, MK-7264, R1646, RG-1646, RO 4926219) is an orally active small molecule antagonist of human P2X3 receptor with IC50 of about 30 nM, 100–250 nM for recombinant hP2X3 homotrimers and hP2X2/3 heterotrimeric receptors, respectively. Gefapixant has shown promise for the treatment of refractory and unexplained chronic cough.

Selective hP2X2/3, IC50: 100-250 nM; hP2X3, IC50: 30 nM
S7705 A-438079 HCl
