General description
A cell-permeable and reversible naphthoyl fused benzimidazole compound that acts as a highly selective, potent, ATP-competitive inhibitor of Ca2+/calmodulin-dependent protein kinase kinase (CaM-KK) [IC50 = 120 ng/ml and 40 ng/ml for CaM-KKα and CaM-KKβ isoforms, respectively]. Binds to the catalytic domain of CaM-KK, and inhibits autophosphorylation. Does not significantly affect the activities of CaM-KII, MLCK (IC50 = ~10 µg/ml), CaM-KI, CaM-KIV, PKA, PKC, and p42 MAP kinase (IC50 >10 µg/ml). Has also been reported to inhibit phosphorylation of AMP-activated protein kinase (AMPK).
