4-(4-(2,3-dihydrobenzo(1,4)dioxin-6-yl)-5-pyridin-2-yl-1H-imidazol-2-yl)benzamide

개요D 4476 is a cell-permeant inhibitor of casein kinase 1 (CK1; IC50 = 200 nM from S. pombe, 300 nM for CK1δ). It is a less effective inhibitor of PKD1 (IC50 = 9.1 μM) and p38α MAPK (IC50 = 5.8 μM), and only weakly affects the activities of a panel of kinases tested. D 4476 blocks CK1-mediated phosphorylation of FOXO1a, RhoB, and p53. As an inhibitor of ALK5, D 4476 prevents Smad3 activation and suppresses TGF-β1-induced gene expression without cytotoxicity in A498 cells.

용도4-[4-(2,3-Dihydro-1,4-benzodioxin-6-yl)-5-(2-pyridinyl)-1H-imidazol-2-yl]-benzamide is a novel CK1 inhibitor that potently inhibits CK1 with an IC50 value of 78 nM.
