生物活性

製品説明 LJI308は、強力なパンRSK(p90リボソームS6キナーゼ)阻害剤であり、RSK1、RSK2、RSK3に対するIC50値はそれぞれ6 nM、4 nM、13 nMです。
in vitro In MDA-MB-231 and H358 cells, LJI308 blocks cellular inhibition of RSK and its phosphorylation of YB1 on Ser102 with EC50 of 0.2–0.3 μM, and thus inhibits cell growth. In TNBC HTRY-LT cells, this compound also suppresses cell growth correlative with YB-1 inhibition.

キナーゼアッセイ Inhibition of RSK1, RSK2, and RSK3 activity
Enzymatic activity of RSK isoforms 1, 2, and 3 is assessed using recombinant full-length RSK protein. RSK1 (1 nM), RSK2 (0.1 nM), or RSK3 (1 nM) is allowed to phosphorylate 200 nM peptide substrate (biotin-AGAGRSRHSSYPAGT-OH) in the presence of ATP at concentration equal to the Km for ATP for each enzyme (RSK1- 5 μM, RSK2- 20 μM, RSK3- 10 μM) and appropriate dilutions of this compound in 50 mM HEPES, pH 7.5, 10 mM MgCl2, 1 mM DTT, 0.1% BSA Fraction V, 0.01% Tween-20. After 150 min at room temperature, the reaction is stopped with 60 mM EDTA and extent of peptide phosphorylation was determined using an anti-phospho-AKT substrate antibody and AlphaScreen reagents as described by the manufacturer.
細胞アッセイ 細胞株 MDA-MB-231 and H358 cells
濃度 ~100 μM
反応時間 72 h
実験の流れ Cell growth under attached conditions is assessed by plating 1000 cells per well on 96-well tissue culture-treated plates in cell growth medium. Appropriate dilutions of this compound are added to medium above cells and cell growth was assessed after 72 hrs by addition of CellTiter Glo reagent according to manufacturer’s directions.
