Dyclonine Hydrochloride

DescriptionDyclonine hydrochloride is the hydrochloride salt of Dyclonine. Dyclonine belongs to a kind of oral anaesthetic. It is contained in the “Sucrets” as well as some kinds of Cepacol sore throat spray as an active ingredient. Dyclonine takes effect through reversibly binding to the activated sodium channels located on the neuronal membrane. This decreases the permeability of sodium across the neuronal membrane, further increasing the threshold for excitation. Overall, Dyclonine stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and further suppressing the subsequent conduction. This causes a transient and reversible anaesthetic effect in a local area of the body.

UsesDyclonine hydrochloride is used for the temporary relief of the following occasional mouth and throat symptoms: pain, minor irritation, sore mouth and sore throat. It is a sodium channel blocker and a HSP90 chaperone protein inhibitor. It shows local anesthetic effects in vivo and is orally active.

DescriptionDyclonine (536-43-6) is a topical anesthetic which has been used for oral and throat analgesia.1 Enhances neuronal mitochondrial function, potentiating respiration and providing protection against insults associated with neurodegenerative disorders.2 Inhibits aldehyde dehydrogenase ALDH3A1 resulting in accumulation of 4-hydroxynonenal, which renders head and neck squamous cell carcinoma cells sensitive to the cystine-glutamate antiporter inhibitor, sulfasalazine.3 Rescues frataxin deficiency in animal models as well as in buccal cells of patients with Friedreich’s Ataxia.4 Enhances the cytotoxic effect of proteasome inhibitors MG-1325 and bortezomib6 in cancer cells.
