Description

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.

H₁ histamine receptor antagonist.
