calmodulin antagonist-1

Calmodulin antagonist-1 (W-7) is a calmodulin (CaM) antagonist that effectively inhibits calmodulin-activated Ca 2+ -phosphodiesterase (PDE) with an IC 50 of 28 μM. This compound also competitively inhibits trypsin-treated Ca 2+ -PDE with respect to cyclic GMP, exhibiting an IC 50 of 375 μM and a K i value of 300 μM.

W-5 hydrochloride (N-(6-Aminohexyl)-1-naphthalenesulfonamide HCl) is a potent calmodulin antagonist.

CALP2 TFA, a potent calmodulin (CaM) antagonist with a dissociation constant (Kd) of 7.9 µM, exhibits high affinity for the CaM EF-hand/Ca2+-binding site. This compound effectively inhibits CaM-dependent phosphodiesterase activity and elevates intracellular Ca2+ concentrations. Furthermore, it significantly hinders adhesion and degranulation, while also acting as a robust activator of alveolar macrophages [1] [2] [3] [4].

Calmodulin-Dependent Protein Kinase II (290-309) acetate is a potent CaMK antagonist with an IC50 of 52 nM for the inhibition of Ca2+/calmodulin-dependent protein kinase II [1].
