Abstract
Eleven compounds belonging to the chalcone family were tested for their ability to activate and subsequently desensitize the rat transient receptor potential ankyrin 1 cation channel, subfamily A, member 1 (TRPA1) in a heterologous expression system. Four of the tested compounds were more potent than the TRPA1 agonist mustard oil, and showed also a strong desensitizing effect. Some chalcone compounds were not pungent in the eye-wiping assay and quite remarkably inhibited in a long-lasting and dose-dependent manner the pain response in the formalin test. Chalcones can be considered as novel candidates for the development of antihyperalgesic preparations based on TRPA1 desensitization.
