| Hazard Information | Back Directory | [Description]
Protein kinase A (PKA) regulates multiple signal transduction events via protein phosphorylation and is integral to all cellular responses involving the cyclic AMP second messenger system. KT 5720 is one of a family of compounds synthesized by the fungus Nocardiopsis sp. It blocks PKA signaling through competitive inhibition of ATP with a Ki value of 60 nM. Reported IC50 values vary widely depending upon ATP concentration tested and can range from 56 nM (low ATP) to 3 μM (physiologic ATP). Non-specific effects of KT 5720 include inhibition of phosphorylase kinase, PDK1, MEK, MSK1, PKBα, and GSK3β at concentrations as effective as or more potent than that for inhibition of PKA. | [Chemical Properties]
White solid | [Uses]
KT 5720 is a potent, specific and cell-permeable inhibitor of PKA. | [Definition]
ChEBI: An organic heterooctacyclic compound that is 1H,1'H-2,2'-biindole in which the nitrogens have undergone formal oxidative coupling to positions 2 and 5 of hexyl (3S)-3-hydroxy-2-methyltetrahydrofuran-3-
arboxylate (the 2R,3S,5S product), and in which the 3 and 3' positions of the biindole moiety have also undergone formal oxidative coupling to positions 3 and 4 of 1,5-dihydro-2H-pyrrol-
-one. | [Biological Activity]
Potent, selective inhibitor of protein kinase A (K i = 60 nM). Has no effect on PKG or PKC (K i > 2 μ M). Reversibly arrests human skin fibroblasts in the G 1 phase. Also available as part of the Mixed Kinase Inhibitor Tocriset™ and PKA Tocriset™ . | [Biochem/physiol Actions]
Cell permeable: yes | [storage]
