Probe Selectivity in
Vitro:
Selectivity within target family - Selectivity against family members was tested, all > 30 fold: hTRPV1 IC50 > 25 µM, hTRPV4 IC50 > 25 µM, hTRPC3 IC50 > 25 µM, hTRPC5 IC50 = 5.6 µM, hTRPC6 IC50 > 25 µM, hKCNK9 (TASK-3) IC50 > 30 µM, hCACNA1H (Cav3.2) IC50 > 25 µM.
Selectivity outside target family - Selectivity in Eurofins Lead Profiling Screen, GPCR Profiling Screen and Bayer Kinase Panel was performed. Closest off-targets: SLC6A3 (human) Ki = 0.9 μM, PGR (human) Ki = 4 μM, ESR1 EC50 = 2.1 μM. Two off-targets in the GPCR scan: SLC6A3 Ki = 1377.15 nM, HTR2A Ki = 2576.32 nM.
