Biological Activity

[Description]:

Calmidazolium chloride (R 24571) is a calmodulin (CaMK) antagonist, antagonizing CaM-dependent phosphodiesterase and calmodulin-induced activation of erythrocyte Ca2+-transporting ATPase with IC50s of 0.15 and 0.35 μM, respectively[1]. Also in anti-cancer research[2]. Calmidazolium binds to CaMK with a Kd of 3 nM.

Kd: 3 nM (Calmodulin)[3]

[In Vitro]

Calmidazolium chloride is widely used as a calmodulin (CaM) antagonist, but is also known to induce apoptosis in certain cancer cell lines. Calmidazolium chloride (3, 5, 7, 10 μM, 30 minutes-24 hours) inhibits growth of mouse F9 ECCs[2]. Cell Viability Assay[2] Cell Line: Mouse F9 ECCs Concentration: 3, 5, 7, 10 μM Incubation Time: 30 minutes-24 hours Result: The IC50s of Calmidazolium chloride treated F9 ECCs and E14 ESCs are 8.18 μM, and 12.69 μM[2].
