Off-Target Selectivity Assesments

Probe Selectivity in Vitro:

GSK2982772 shows more than 1,000-fold selectivity for ERK5 over a panel of over 339 kinases Reaction Biology and on competition binding assay KINOMEscan at DiscoveRx Corp (456 kinases) both at 10 μM.

Probe Selectivity in Cell:

GSK2982772 demonstrated a clean profile against a range of nonkinase targets. No inhibitory potential toward recombinant human cytochrome P450 (CYP) enzymes, with the exception of weak activity against CYP2C9 (IC50 = 25 μM). Weak concentration-dependent inhibition of hERG in human embryonic kidney (HEK-293) cells, with an estimated IC50 of 195 μM, and showed a weak activation of the human Pregnane X receptor (hPXR) with an EC50 of 13 μM.

SERP Comments:

The probe should be used in cellular system in combination with its enantiomer as negative control. Importantly, this probe shows significant species-differences as outlined by the authors in the J. Med. Chem. paper. Therefore, the probe can only be used in rodent acute models at relatively high doses (5-50 mg/Kg po, total systemic concentration significantly exceeding the recommended concentration range for cellular studies). When using the probe at these doses observed phenotypes will have to be linked back to on target activity by providing PK-PD correlations for proximal PD markers or the used of ko animals as controls.

SERP Comments:

The enantiomer is very useful as a negative control probe. For orthogonal probe, e.g. in Cortellis Drug Discovery Intelligence there are 286 small molecules with Mw <750 g/mol that are used in either biological testing or preclinical phase as RIPK1 inhibitors.
