Application

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

Biochem/physiol Actions

Capsazepine is a synthetic analog of capsaicin and a transient receptor potential vanilloid-1 (TRPV1) antagonist. It exhibits anti-proliferative and anti-cancer effects in various cancer types including oral squamous cell carcinoma, non-small cell lung cancer (NSCLC), breast cancer, and prostate cancer cell lines (HSC-3, H460, MDA-231, and PC-3 respectively). Capsazepine recovers impaired lung mechanics during endotoxemia and it may be a potential therapeutic target for acute lung injury (ALI).

1. Capsazepine is a synthetic analogue of the sensory neurone excitotoxin, capsaicin. The present study shows the capsazepine acts as a competitive antagonist of capsaicin. 2. Capsazepine (10 microM) reversibly reduced or abolished the current response to capsaicin (500 nM)

We previously demonstrated that capsazepine (CPZ), a synthetic transient receptor potential Vanilloid subtype 1 (TRPV1) antagonist, has significant anti-cancer effects in vivo. The purpose of this study was to develop more potent analogs based upon CPZ pharmacophore and structure-activity relationships

Extracellular signal-regulated kinase (ERK) is known to be phosphorylated after exposure to noxious stimuli. In this study, we investigated the response in the dura mater to nociceptive stimulation, which is thought to be responsible for the pathogenesis of headaches, including

Acute lung injury (ALI) caused by systemic inflammatory response remains a leading cause of morbidity and mortality in critically ill patients. Management of patients with sepsis is largely limited to supportive therapies, reflecting an incomplete understanding of the underlying pathophysiology.
