| Common Name | Methyl nicotinate |

| Description | Methyl nicotinate, also known as heat spray or 3PYRCOOME, belongs to the class of organic compounds known as pyridinecarboxylic acids. Pyridinecarboxylic acids are compounds containing a pyridine ring bearing a carboxylic acid group. Methyl nicotinate is a strong basic compound (based on its pKa). Methyl nicotinate is a herbal, tobacco, and warm tasting compound. Outside of the human body, Methyl nicotinate has been detected, but not quantified in, several different foods, such as alcoholic beverages, coffee and coffee products, fruits, nuts, and papaya. This could make methyl nicotinate a potential biomarker for the consumption of these foods. For veterinary purposes, methyl nicotinate is used to treat respiratory diseases, vascular disorders, rheumatoid arthritis, and muscle and joint pains. During tissue penetration at the dermis, methyl nicotinate is hydrolyzed to nicotinic acid. In humans, oral ingestion of 3-9 g of nicotinic acid per day resulted in "niacin hepatitis", gout, and impaired glucose intolerance within a short period of time. It was demonstrated in human subjects that the local cutaneous vascular response to methyl nicotinic was suppressed by inhibitors of prostaglandin biosynthesis, indicating that the effect of methyl nicotinate on vascular smooth muscles may be mediated by the release of local prostaglandins. Following topical administration, methyl nicotinate acts as a peripheral vasodilator to enhance local blood flow at the site of application. In human volunteers, topical administration of methyl nicotinate caused vasodilation-induced generalized cutaneous erythema. The action of methyl nicotinate as a rubefacient is thought to involve peripheral vasodilation. Prostaglandins released from the skin and blood vessels induce cutaneous vasodilation. Methyl nicotinate is found in Annona muricata , Areca catechu , Carica papaya, Chaenomeles speciosa, Coffea arabica, Daphne papyracea, Mycobacterium bovis, Mycobacterium tuberculosis, Osmanthus austrocaledonica and Osmanthus austrocaledonicus. Methyl nicotinate was first documented in 2012 (PMID: 22845897). The hydrolysis is thought to be mediated by nonspecific α-naphthylacetate-esterase at the dermis layer of the skin. |
