生物活性

製品説明 D 4476 is a potent, selective, and cell-permeant CK1 (casein kinase 1) inhibitor with IC50 of 200 nM and 300 nM in a cell-free assay for CK1 from Schizosaccharomyces pombe and CK1δ, respectively. Also acts as an ALK5 inhibitor with IC50 of 500 nM.
in vitro D4476 (10 μM) effectively inhibits CK1 and ALK5 with the activities of about 7% and 22% versus control group, respectively. In H4IIE hepatoma cells, D4476 specifically inhibits the phosphorylation of endogenous forkhead box transcription factor O1a (FOXO1a) on Ser322 and Ser325, without affecting the phosphorylation of other sites.[1] D4476 induces cytotoxicity in ANBL6, INA6 and RPMI8226 lines; MM1S and U266 lines are less sensitive; and OPM1 line is totally resistant. High concentrations (50 μM) D4476 induced toxicity in all multiple myeloma (MM) lines. In MM cells, D4476 increases the protein levels of TP53, P27, and FADD, as well as the cell cycle progression and induction of apoptosis.[2] Treatment of leukemia stem cells (LSCs) with D4476 shows highly selective killing of LSCs over normal HSPCs.[3]

キナーゼアッセイ CK1 kinase assay
All protein kinase assays (25 μL) are carried out at room temperature (21℃). Assays are performed for 40 min using a Biomek 2000 Laboratory Automation Workstation in a 96-well format. The concentrations of magnesium acetate and [γ-33P]ATP (800 cpm/pmol) in the assays are 10 mM and 0.1 mM, respectively. Assays are initiated with MgATP and stopped by the addition of 5 μL of 0.5 M orthophosphoric acid. Aliquots are then spotted on to P30 filtermats, washed four times in 75 mM phosphoric acid to remove ATP, once in methanol, then dried and counted for radioactivity. CK1 δ (5-20 m-units), diluted in 20 mM Hepes, pH 7.5, 0.15 M NaCl, 0.1 mM EGTA, 0.1% (v/v) Triton X-100, 5 mM dithiothreitol, 50% (v/v) glycerol, is assayed against the peptide RRKDLHDDEEDEAMSITA in an incubation containing 20 mM Hepes, pH 7.5, 0.15 M NaCl, 0.1 mM EDTA, 5 mM DTT, 0.1% (v/v) Triton X-100 and 0.5 mM substrate peptide.
細胞アッセイ 細胞株 MM cell lines including MM1S, RPMI8226, U266, MM1R, OPM1, OPM2, INA6, ANBL6, ANBL-6VR, LR5 and RPMI-DOX40 (DOX40) cells
濃度 50 μM
反応時間 72 h
実験の流れ MM cells are seeded in triplicate into 96-well plates in 100 μL culture media. D4476 is added to each well at concentrations of 0, 5, 10, 20, 30, 40, and 50 μM in another 100 μL culture media. Cell viability is measured with MTT at the 72 h drug exposure. Absorbance is measured at 570 nm with spectrophotometer.
