3、M。IC50 & Target PI3K12 nM (IC50)1/2 Master of Small Molecules 您邊的抑制劑師www.MedChemE體外研究 Seletalisib is a potent, ATP-competitive and highly selective PI3K inhibitor able to block AKTphosphorylation following activation of the BCR in a B-cell line. Seletalisib inhibits N-formyl peptides (fMLP)-stimulat

4、ed but not phorbol myristate acetate (PMA)-stimulated superoxide release from human neutrophilsconsistent with a PI3K-specific activity. No indications of cytotoxicity are observed in PBMCs or other celltypes treated with seletalisib. seletalisib blocks human T-cell production of several cytokines f

5、rom activatedT-cells. Seletalisib inhibits T-cell differentiation to Th1, Th2, and Th17 subtypes. Additionally, seletalisibinhibits B-cell proliferation and cytokine release. In human whole blood assays, seletalisib inhibits CD69expression upon B-cell activation and anti-IgE-mediated basophil degran

6、ulation 1.體內研究 Seletalisib significantly inhibits IL-2 release following TCR stimulation in the rat. The inhibition is observed atall tested doses of seletalisib with almost complete inhibition reached at dose levels 1 mg/kg. Seletalisib haspotent in vivo effects with an estimated IC50 value of 1.PR

7、OTOCOLKinase Assay 1 Seletalisib is dissolved 1 mM solution in DMSO, and tested in a concentration response (seletalisib), toexplore the effects of PI3K-specific inhibition compared with complete inhibition of class I PI3K signaling. Inaddition, seletalisib is tested in the BioMap BT cell system at

8、concentrations of 1000, 100, 10, and 1 nM. Anactivity profile is generated based on the effect of the compounds on the levels of cellular readouts, includingcytokines, growth factors, adhesion molecules, and proliferation endpoints 1.MCE has not independently confirmed the accuracy of these methods.
