Description and Uses

W-13 is a naphthalenesulfonamide derivative that acts as a potent antagonist of calmodulin (IC₅₀ = 22 μM) and is widely used to investigate Ca²⁺/calmodulin-regulated enzyme activities.

Calmodulin antagonist that binds to calmodulin and inhibits calcium-ion-calmodulin- regulated activities, including phosphodiesterase activation and myosin light chain kinase127, it is widely used to investigate Ca2+/calmodulin-regulated enzyme activities.
