BAY-1797 是一种高效、具有口服活性的,选择性的P2X4拮抗剂,对人 P2X4 的IC50为 211 nM。BAY-1797 在其它 P2X 离子通道上没有或表现出很弱的活性。BAY-1797 具有抗伤害和抗炎作用。
生物活性 | BAY-1797 is a potent, orally active, and selectiveP2X4antagonist, with anIC50of 211 nM against human P2X4. BAY-1797 displays no or very weak activity on the other P2X ion channels. BAY-1797 shows anti-nociceptive and anti-inflammatory effects[1]. |
IC50& Target | IC50: 211 nM (human P2X4), >50 μM (human P2X1), >30 μM (human P2X23), 8.3 μM (human P2X3), 10.6 μM (human P2X7)[1] |
体外研究 (In Vitro) | BAY-1797 inhibits human, mouse, and rat P2X4 in 1321N1 cells with IC50s of 108 nM, 112 nM, and 233 nM, respectively[1]. BAY-1797 exerts no measurable activity on hERG and carbonic anhydrase II (both IC50>10 μM). BAY-1797 is also tested against a panel of off-targets, including G-protein coupled receptors (GPCRs), ion channels, kinases, and transporters at 10 μM. An inhibitory activity against the dopamine transporter (DAT, IC502.17 μM) was revealed as the only hit[1].

体内研究 (In Vivo) | BAY-1797 (12.5-50 mg/kg; p.o.) shows a significant induction of PGE2 levels in the inflamed paw in the mouse Complete Freund’s Adjuvant (CFA) inflammatory pain model[1]. BAY-1797 (50 mg/kg; once daily for multiple p.o. administrations) induces a significant reduction of the ipsilateral paw load 24 and 48 h after CFA injection[1]. BAY-1797 treatment shows the AUCnorm, Vssand t1/2are 1.06 kg h/L, 3.67 L/kg and 2.64 hours, respectively[1].
Animal Model: | Female adult C57BL/6N mice (CFA inflammatory pain model)[1] | Dosage: | 12.5, 25, 50 mg/kg | Administration: | p.o.; once | Result: | Dose-dependently reduced PGE2 concentration in inflamed paw. |
Animal Model: | Rat male Wistar[1] | Dosage: | 1 mg/kg | Administration: | i.v. (Pharmacokinetic Analysis) | Result: | The AUCnorm, Vssand t1/2were 1.06 kg h/L, 3.67 L/kg and 2.64 hours, respectively. |
