Lavendustin C is a potent Ca2+ calmodulin-dependent kinase II (CaMK II) inhibitor with an IC50 of 0.2 µM. Lavendustin C inhibits EGFR-associated tyrosine kinase (IC50=0.012 µM) and pp60c-src(+) kinase (IC50=0.5 µM) [1][2].
CaMKII inhibitory peptide KIIN is a potent inhibitor of CaMKII[1][2].
Autocamtide 2 is a highly selective peptide substrate of calcium/calmodulin-dependent protein kinase II (CaMKII). It can be used in the CaMKII activity assay.
Acremonidin A is a potent calmodulin (CaM) inhibitor found in Purpureocillium lilacinum. Acremonidin A binds to the human calmodulin (hCaM) biosensor hCaM M124C-mBBr, with Kd of 19.40 nM[1].
Metofenazate is a selective calmodulin inhibitor.
Calmidazolium chloride (R 24571) is a calmodulin (CaMK) antagonist, antagonizing CaM-dependent phosphodiesterase and calmodulin-induced activation of erythrocyte Ca2+-transporting ATPase with IC50s of 0.15 and 0.35 μM, respectively[1]. Also in anti-cancer research[2]. Calmidazolium binds to CaMK with a Kd of 3 nM.
KN-92 is an inactive derivative of KN-93. KN-93 is a selective inhibitor of Ca2+/calmodulin-dependent kinase II (CaMKII), competitively blocking CaM binding to the kinase (Ki = 370 nM). IC50 value:Target: KN-92 is intended to be used as a control compound in studies designed to elucidate the antagonist activities of KN-93. KN-93 inhibits histamine-induced aminopyrine uptake in parietal cells (IC50 = 300 nM). KN-93 has been used to implicate roles for CaMKII in Ca2+-induced Ca2+ release in cardiac myocytes, constitutive phosphorylation of 5-lipoxygenase in 3T3 cells, and Ca2+-dependent activation of HIF-1α in colon cancer cell.
Rimacalib is a Ca2+/calmodulin-dependent protein kinase II (CaMKII) inhibitor, with IC50s of ~1 μM for CaMKIIα to ~30 μM for CaMKIIγ.
KN-93 hydrochloride is a cell-permeable, reversible and competitive inhibitor calmodulin-dependent kinase type II (CaMKII) with a Ki of 370 nM.
