314.29 (free base basis)

A cell-permeable and reversible napthoyl-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). Reported to bind to the catalytic domain of CaM-KK, and inhibit 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).
