Description
W-
13 is a naphthalenesulfonamide derivative that acts as a potent antagonist of calmodulin (IC
50 = 22 μM) and is widely used to investigate Ca
2+/calmodulin-
regulated enzyme activities.
Chemical Properties
Beige Solid
Uses
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.
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.
Definition
ChEBI: N-(4-aminobutyl)-5-chloronaphthalene-2-sulfonamide hydrochloride is a hydrochloride salt prepared from equimolar amounts of N-(4-aminobutyl)-5-chloronaphthalene-2-sulfonamide and hydrogen chloride. It contains a N-(4-aminobutyl)-5-chloronaphthalene-2-sulfonamide(1+).
Biological Activity
Calmodulin antagonist (inhibits calmodulin activated PDE activity with an IC 50 of 68 μ M). Inhibits growth of tamoxifen-resistant breast cancer cells.
Biochem/physiol Actions
W-13 has also been shown to inhibit the transcytosis of IgA, recycling of transferrin and overall alter the endocytic pathway in Madin-Darby canine kidney cells.
