KN-93 is a selective inhibitor of Ca2+/calmodulin-dependent kinase II (CaMKII), competitively blocking CaM binding to the kinase.

KN-93 phosphate is a novel membrane-permeant synthetic inhibitor of purified neuronal CaMK-II with K i of 370 nM. KN-93 phosphate inhibits serum-induced fibroblast cell growth in a comparable dose-dependent fashion to its inhibition of CaMK-II activity.

KN-93 hydrochloride is a cell-permeable, reversible and competitive calmodulin-dependent kinase type II ( CaMKII ) inhibitor with a K i of 370 nM.

KN-92 phosphate (KN92-H3PO4) 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).

KN-92 hydrochloride is an inactive derivative of KN-93. KN-93 is a selective Ca2+/calmodulin-dependent kinase II (CaMKII) inhibitor, competitively blocking CaM binding to the kinase with Ki of 370 nM.

KN-92 is an inactive analog of the CaM kinase II inhibitor KN 93.
