生物活性
KN-62 是一種有效,選擇性的鈣調蛋白依賴性蛋白激酶 II (CaMK-II)抑制劑,IC50 為 0.9 μM, KN-62 也是非競爭性的 P2X7 受體拮抗劑,IC50 約為 15 nM。
靶點

IC50: 0.9 μM (CaMK II), 15 nM (P2X 7 receptor, in HEK293 cells)

體外研究

KN-62 is a selective antagonist of Ca 2+ /calmodulin-dependent protein kinase II (CaMKII). KN-62 potently antagonizes ATP-stimulated Ba 2+ influx into fura-2 loaded human lymphocytes with an IC 50 of 12.7±1.5 nM (n=3) and complete inhibition of the flux at a concentration of 500 nM. Similarly, KN-62 inhibits ATP-stimulated ethidium + uptake, measured by time resolved flow cytometry, with an IC 50 of 13.1±2.6 nM (n=4) and complete inhibition of the flux at 500 nM. KN-62 is found to be a potent antagonist in a functional assay, inhibition of ATP-induced K + efflux in HEK293 cells expressing recombinant human P2X 7 receptors. In human leukemic B lymphocytes, KN-62 reduces the rate of permeability increase to larger permeant cations, like ethidium, induced by Bz-ATP with an IC 50 of 13.1 nM. KN-62 at a concentration of 3 μM has no effect on ATP-induced ethidium influx through the rat P2X 7 receptor, while the IC 50 at the human P2X 7 receptor is 0.1 μM. KN-62 has considerable selectivity for P2X 7 receptors within the P2 family.

體內研究

The antidepressant-like behavior of ZnCl 2 (10 mg/kg, p.o.) (p<0.01) is prevented by CAMKII inhibitor KN-62 (1 μg/site, i.c.v.). The two-way ANOVA reveals a significantly main effect of KN-62 treatment [F(1,28)=27.47, p<0.01], no main effect of ZnCl 2 treatment [F(1,28)=0.84, p>0.05] and a significant effect of KN-62×ZnCl 2 treatment interaction [F(1,28)=22.57, p<0.01] to immobility time. As revealed by the post-hoc analysis, the anti-immobility effect of ZnCl 2 is completely prevented by treatment of animals with KN-62. No effect in locomotor activity in the open-field test is observed: (KN-62 treatment [F(1,24)=1.97, p>0.05], ZnCl 2 treatment [F(1,24)=3.99, p>0.05] and KN-62×ZnCl 2 treatment interaction [F(1,24)=0.61, p>0.05]).
