Inhibiteur de RSK; SL0101

Non disponible en dehors du Royaume-Uni et de l'Irlande

General description

A cell-permeable Kaempferol (Cat. No. 420345) glycoside that targets the the N-terminal kinase domain of p90 ribosomal S6 kinase and inhibits RSK kinase activity (IC₅₀ = 89 nM with 10 µM ATP) in a selective, reversible, and ATP-competitive (K_i = 1 µM) manner. Shown to inhibit the proliferation of MCF-7, but not the normal breast cell line MCF-10A, and specifically block PDB-induced cellular phosphorylation of RSK substrate p140, but not that of RSK or RSK upstream kinases even at concentrations as high as 100 µM.
