Description: Blocks voltage-sensitive Na+ and Ca2+ channels (T-type)
Alternative Names: AD 810,CI 912
Chemical Name: 1,2-Benzisoxazole-3-methanesulfonamide
Purity: ≥99% (HPLC)
Biological Activity for Zonisamide
Zonisamide is a antiepileptic that possesses a broad spectrum anticonvulsant and mechanistic profile. Blocks voltage-sensitive Na+ and T-type Ca2+ channels, stimulates BKCa channels, modulates GABA, glutamate and monoamine neurotransmission, inhibits lipid peroxidation and scavenges hydroxyl and nitric oxide free radicals. Displays neuroprotective and antiParkinsonian activity.

Zonisamide was used on Cav3.1 and Cav3.2 channel to understand their blocking capacities.

Zonisamide was used on Cav3.1 and Cav3.2 channel to understand their blocking capacities at increasing concentrations.We aimed to decrease calcium conductance through the channels as increase leads to increased depolarization and excitability.
