KN-62, Thermo Scientific Chemicals

It is used as a potent and selective inhibitor of CaMKII. KN-62 has demonstrated potent and selective inhibition of Ca2+/calmodulin-dependent protein kinase II (CaMKII; Ki=0.9 ?M) which causes cells to arrest in the S phase. In HEK-293 cells expressing type III adenylyl cyclase (III-AC), 10 ?M of KN-62 blocked CaMKII phosphorylation of III-AC, and inhibited hormone-stimulated Ca2+ oscillations. Additionally, KN-62 is a potent non-competitive antagonist at the P2X7 receptor (IC50 = 15 nM).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
