 halazone Biological Activity

Description Halazone is an atypical antimicrobial sulfonamide derivative and a carbonic anhydrase II inhibitor with a Kd value of 1.45 µM. Halazone protects sodium channels from inactivation. Halazone is widely used for disinfection of drinking water[1][2].
Related Catalog
In Vitro Halazone is chemically closely related to Chloramine-T, the nitrogen atom is linked with two instead of one chlorine atom and, certainly more important here, a methyl group is replaced by a carboxyl group. The effect of Halazone on the sodium current is studied in voltage-clamped single nerve fibers of the frog. The oxidant Halazone drastically inhibits inactivation[1].
