Description and Uses

Transient receptor potential vanilloid type 1 (TRPV1) is a member of the transient receptor potential (TRP) family that is activated or sensitized by a variety of endogenous stimuli as a result of tissue injury and inflammation. TRPV1 is upregulated during inflammation and plays a role in the perception of pain. Capsazepine is a competitive antagonist of transient receptor potential vanilloid type 1 (TRPV1) which blocks the capsaicin-induced uptake of Ca²⁺ in neonatal rat dorsal root ganglia with an IC₅₀ of 0.42 μM and Chinese hamster ovary cells with an IC₅₀ of 17 nM. It does not block acid- or heat-induced activation of TRPV1 and may block receptors other than TRPV1.

Capsazepine has been used as a transient receptor potential vanilloid-1 (TRPV1) antagonist:

• to study its effect on capsaicin induced extracellular signal-regulated kinase (ERK) phosphorylation
• to study the role of TRPV1 in central terminals on nociception in rats
• for functional characterization of the TRPV1 in bull spermatozoa
