The transient receptor potential ankyrin 1 (TRPA1) is a calcium permeable non-selective cation channel that belongs to the transient receptor potential (TRP) superfamily. The TRPA1 channel is expressed in the sensory neurons of the nodose ganglia, dorsal root ganglia, and trigeminal ganglia, and also non-neuronal cells such as cardiomyocytes, lung fibroblasts and pancreatic β cells. TRPA1 is activated by a range of natural pungent compounds including allyl isothiocyanate (AITC),cinnamaldehyde, and allicin. TRPA1 can also be activated by cold temperature and has been proposed to act as a mechanosensor. Not only has TRPA1 been proposed to play a role in nociception and certain pain conditions, but has also in cardiovascular conditions such as atherosclerosis, heart failure, arrhythmia, vasodilation, and hypertension. Thus, within drug development, much attention is paid to the TRPA1 channel. For example, TRPA1 has been identified as a potential target for persistent chronic painful states including inflammation, neuropathic pain, diabetes, fibromyalgia, bronchitis, and emphysema. Indeed, the TRPA1 antagonist GR 17536 from Glenmark showed efficacy in a Phase IIa proof-of-concept clinical trial for peripheral diabetic neuropathy.
