General description
Clemizole is a potent anti-allergic drug.[1]
Biochem/physiol Actions
Clemizole is a potent and preferring inhibitor of TRPC5 that efficiently blocks heterologously expressed homomeric TRPC5 channels as well as heteromeric TRPC1:TRPC5 channels. Clemizole is a potent and selective H1 histamine receptor antagonist. Clemizole inhibited binding of HCV RNA by NS4B inhibit HCV RNA replication in cell culture.
Clemizole is a potent and preferring inhibitor of TRPC5; Antihistaminic.
Clemizole is an antihistamine and an inhibitor of NS4B (nonstructural protein 4B) RNA of HCV (hepatitis C virus). Studies in Scn1α (sodium channel, voltage-gated, type I, α) Zebrafish mutant show that this drug has the potential as a therapeutic agent in Dravet Syndrome treatment.[2]

Dravet syndrome is a catastrophic pediatric epilepsy with severe intellectual disability, impaired social development and persistent drug-resistant seizures. One of its primary monogenic causes are mutations in Nav1.1 (SCN1A), a voltage-gated sodium channel. Here we characterize zebrafish Nav1.1 (scn1Lab) mutants

Acetylcholine contracts the bladder by binding to muscarinic M3 receptors on the detrusor, leading to Ca2+ influx via voltage-gated Ca2+ channels. The cellular mechanisms linking these events are poorly understood, but studies have suggested that activation of TRPC4 channels could
