KT5823
Based on 13 publication(s) in Google Scholar
KT5823, a selective the cGMP-dependent protein kinase (PKG) inhibitor with an Ki value of 0.23 μM, it also inhibits PKA and PKC with Ki values of 10 μM and 4 μM, respectively. KT5823 is a Staurosporine-related protein kinase inhibitor, increases thyroid-stimulating hormone-induced (Na+/I- symporter) NIS expression, and iodide uptake in thyroid cells. KT5823 arrests cells after the G0/G1 boundary and causes increases in the levels of apoptotic DNA fragmentation.

PKA 10 μM (Ki) |

KT5823 (15 μM, 18 h) arrests HSF55 cells in the G0 or G1 phase of the cell cycle[3].
KT5823 (100 nM and 1 mM, 24 h) causes dose-dependent increases in apoptotic DNA fragmentation in unstressed HRE-H9 cells [3].
KT5823 (0.2-200 μM, 30 min) enhances 8-pCPT-cGMP (HY-137016)-induced VASP phosphorylation, but not inhibits the activation of PKA by Forskolin (HY-15371) in human platelets[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
