Nemiralisib hydrochloride (GSK2269557) is a potent and highly selective PI3Kδ inhibitor with a pKi of 9.9. | [Biological Activity]
pki : 9.9gsk2269557 is an inhibitor of pi3kδ.phosphoinositide 3-kinase delta (pi3kδ), a lipid kinase belonging to the class 1 pi3k family, catalyzes the phosphorylation of phosphatidylinositol-4,5-bisphosphate to produce the critical signalling molecule phosphatidylinositol-3,4,5-triphosphate and then triggers various downstream biological events that ultimately regulate cell proliferation, growth, differentiation, chemotaxis and survival. | [in vitro]
in the screening study, gsk2269557 met the original potency goal in the pbmc assay (pic50 >9) and showed exquisite selectivity against the pi3k isoforms in a modified htrf assay. moreover, gsk2269557 could induce concentration-dependent increases in qt interval and tpe at 0.3 and 1 μm and an increase in qrs at 1 μm, however, no treatment-related tdp arrhythmias were seen [1]. | [in vivo]
in a disease relevant brown norway rat acute ova model of th2 driven lung inflammation, gsk2269557 was found to be albe to protect against eosinophil recruitment with an ed50 of 67 μg/kg. the activity of gsk2269557 was also assessed using other endpoints, leukocyte recruitment to the lung (neutrophils, macrophages, cd4 and cd8 t-lymphocytes at 48 hours) and th2 cytokines such as il-13. it was found that gsk2269557 could reduce recruitment of all leukocyte subpopulations and il-13 in the lungs in a dose-dependent manner [1]. | [IC 50]
