GSK2982772 shows more than 1,000-fold selectivity for ERK5 over a panel of over 339 kinases at 10 μM. In stimulated cellular systems,GSK2982772 is also able to reduce spontaneous production of cytokines (IL-1β and IL-6) in a concentration-dependent fashion from ulcerative colitis explant tissue in overnight incubations. GSK2982772 produces a weak concentration dependent inhibition of hERG in human embryonic kidney (HEK-293) cells, with an estimated IC50 of 195 μM, and also shows a weak activation of the human Pregnane X receptor (hPXR) with an EC50 of 13 μM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In the corresponding TNF/zVAD model, GSK2982772 shows 13, 63, and 93% protection from temperature loss over 3 h. GSK2982772 displays a good free fraction in blood in rats (4.2%), dogs (11%), cynomolgus monkeys (11%), and humans (7.4%)[1].
GSK2982772 has a good pharmacokinetic profile across both rats and monkeys. GSK2982772 distributes into a range of tissues including the colon, liver, kidney, and heart at concentrations comparable to those of blood[1].
However, GSK2982772 has low brain penetration in rat (4%) despite possessing good cell permeability (21×10-6 cm/s)[1].
GSK2982772 itself does not possess good blood-brain barrier (BBB) permeability and may only enter brain tissue under pathological conditions where the BBB is compromised[2].
GSK2982772 (2.5 mg/kg, i.p., once daily for 3 weeks) can cross the compromised BBB in AAV-TAUnk01L transgenic mice (a tauopathy pathological model with potentially increased BBB permeability), exerting an inhibitory effect on TAU-induced astrocyte activation; however, under normal physiological conditions, its BBB permeability is impaired due to P-glycoprotein efflux, making it difficult to enter brain tissue[2].
