In Vivo Data

Off-Target Selectivity Assesments

Probe Selectivity in Vitro:

Selectivity against family members was tested, all > 30 fold (P2RX1 (IC50 > 50 µM), P2RX2 (IC50 > 30 µM), P2RX3 (IC50 = 8.3 µM), P2RX7 (IC50 = 10.6 µM)). Selectivity in Eurofins Lead Profiling Screen, GPCR Profiling Screen and Bayer Kinase Panel was performed (only relevant IC50: SLC6A3 2.2 µM). Closest hits in the GPCR scan are ADRA2B (Ki = 4285.88 nM) and TMEM97 (Ki = 4344.21 nM).

SERP Comments:

BAY-1797 was developed from a high content screening hit to a potent P2X4 inhibitor with high selectivity towards P2X4 over other P2X ion channels. The available biochemical data together with a co-crystal structure of P2X4 with BAY-1797 suggest it is a potent and highly selective inhibitor. BAY-1797 is suitable for in vivo experiments and a related control compound BAY-207 is provided.
