Descripción

Descripción general

A cell-permeable calmodulin antagonist. An analog of sepazonium that is at least 150 times more potent than Trifluoperazine (Cat. No. 642150) as an inhibitor of brain Ca²⁺-calmodulin-dependent phosphodiesterase (IC₅₀ = 10 nM). Inhibits voltage-gated Ca²⁺ channels and stimulates the release of nitric oxide in neuroblastoma cells. Also, acts as a strong inhibitor of calcium-dependent Ca²⁺-ATPase in erythrocytes. Known to prolong cardiac refractory period in vivo.

An inhibitor of voltage-gated Ca²⁺ channels. Stimulates the release of nitric oxide in neuroblastoma cells. Also acts as a strong non-competitive inhibitor of skeletal muscle sarcoplasmic reticulum Ca²⁺-ATPase (K_i = 60 nM). Known to prolong cardiac refractoriness in vivo.

Note: easily adheres to glass in aqueous solution.
