KN-93 hydrochloride is a potent inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMK II) with Ki value of 0.37μM [1].
KN-93 is an inhibitor of CaMK II. It exerts its effect by competing for the calmodulin binding site of CaMK II with IC50 value of 370nM. In isolated gastric parietal cells, KN-93 shows a potent inhibition of acid secretion induced by carbachol and histamine with IC50 values of 0.15μM and 0.3μM, respectively. It also inhibits forskolin induced aminopyrine uptake with IC50 value of 0.6μM. KN-93 is also found to have effects on the H+, K+-ATPase. 10μM KN-93 and 20μM KN-93 can inhibit 26% and 35% activity of the enzyme, respectively. Moreover, KN-93 is reported to act as an extracellular blocker of Kv channels through enhancing C-type inactivation [1, 2].

| Cell experiment[1]: | |
|
Cell lines |
NIH 3T3 fibroblasts |
|
Preparation method |
The solubility of this compound in DMSO is > 10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
24-72 h, 24 μM |
|
Applications |
KN-93 is an inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMK-II). It inhibits fibroblast CaMK-II activity and cell growth in a dose-dependent manner, reversibly arrests cells in G1 and induces apoptosis. |
| Animal experiment [2]: | |
|
Animal models |
8-24-week-old CaMKIV TG mice |
|
Dosage form |
10 to 30 μmol/kg IP |
|
Application |
KN-93 significantly suppressed isoproterenol-induced arrhythmias in CaMKIV TG mice compared with isoproterenol-treated WT mice, indicating CaMKII is a proarrhythmic molecule in the mouse model of cardiac hypertrophy. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
