Off-Target Selectivity Assesments

Probe Selectivity in Vitro:

Selectivity within target family: Selectivity against a broad range of GPCR‘s. Clean GPCR scan except for weak activity on TMEM97 (Ki = 1107.9 nM). Eurofins-Panlabs radioligand binding assay: The closest off-target is CNR1 with IC = 3.44 µM at 3 µM. Selectivity outside target family: Eurofins-panlabs enzyme assay: The closest off-targets found at 10 µM are MAPK3 with IC50= 4.87 µM and MAPK14 with IC50 = 10.7 µM.

SERP Comments:

Probe BAY-784 is an effective "partial antagonist" of GNRHR at two digit nanomolar, it can reduce the LH level ~up to 50% from base level in various testing model (cell, animal, human). For off-target screening, when tested at 1uM or 10uM against vast panels of kinase, GPCR, ion channel proteins (in vitro or in cell), no significant interference on these protein's activity or function was observed. The reason not giving a 4 star is because that in-situ or in cell chemical proteomics profiling is currently unavailable.

SERP+ Comments:

This is a well validated compound. It would have been useful to see Cmax. The unbound fraction is low for this clinical candidate 5a/BAY-1214784 (1.4%).
