| Description | BAY-1797 is an orally active and selective P2X4 antagonist (IC50: 211 nM against human P2X4) with anti-nociceptive and anti-inflammatory effects. BAY-1797 displays no or very weak activity on the other P2X ion channels. |
| Targets&IC50 | P2X4 (human):211 nM , P2X7 (human):10.6 μM , P2X23 (human):>30 μM , P2X1 (human):>50 μM , P2X3 (human):8.3 μM |
| In vitro | BAY-1797 inhibits human, mouse, and rat P2X4 in 1321N1 cells (IC50s: 108 nM, 112 nM, and 233 nM). BAY-1797 exerts no measurable activity on hERG and carbonic anhydrase II (both IC50>10 μM). BAY-1797 (10 μM) is also tested against a panel of off-targets, including GPCRs, ion channels, kinases, and transporters. Inhibitory activity against the dopamine transporter (IC50: 2.17 μM) was revealed as the only hit. |
| In vivo | BAY-1797 (12.5-50 mg/kg; p.o.) significantly induces PGE2 levels in the inflamed paw in the mouse Complete Freund’s Adjuvant (CFA) inflammatory pain model. At 50 mg/kg daily, BAY-1797 significantly reduces ipsilateral paw load 24 and 48 hours post-CFA injection. Pharmacokinetic parameters include AUCnorm of 1.06 kg h/L, Vss of 3.67 L/kg, and t1/2 of 2.64 hours. |

Solution Preparation Table | ||||||||||||||||||||||||||||||||||||
DMSO
| ||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
