9. Other Information
9.0 Usage
Used as a rubefacient, topical vasodilator used to test the efficacy of skin protection compounds (i.e. products designed to provide barriers to chemical warfare agents) and used as a flavoring agent. It is a useful synthetic intermediate. It can be used to prepare biarylcarboxamide inhibitors of phosphodiesterase IV and tumor necrosis factor-α in treatment of rheumatoid arthritis.
9.1 Absorption
The presence of methyl group facilitates the penetration of methyl nicotinate through the skin with good lipophilicity, allowing rapid absorption following topical administration. _In vitro_, about 80-90% of the polar compounds methyl nicotinate rapidly penetrated the skin. It was demonstrated in excised skin of hairless mice that methyl nicotinate can effectively bypass the stratum corneum layer of the skin. In humans, nicotinic acid and nicotinamide were shown to be rapidly absorbed from the stomach and intestine via a sodium carrier-mediated mechanism at low concentrations.|Following epicutaneous administration of small radiolabelled dose of methyl nicotinate in human volunteers, approximately 15% of the dose was recovered in the urine within 108 hours after treatment. The excretion of nicotinic acid mainly takes place in the kidneys.|According to the animal studies, nicotinic acid is mainly concentrated in the liver, kidneys, and adipose tissue.|No pharmacokinetic data available.
9.2 Metabolism
Methyl nicotinate undergoes ester hydrolysis to form nicotinic acid and methanol. The hydrolysis is thought to be mediated by nonspecific α-naphthylacetate-esterase at the dermis layer of the skin.
9.3 Biological Half Life
_In vitro_, the half-life of methyl nicotinate in the dermis was 3 to 10 minutes.
9.4 Mesh Entry Terms

9.9 Description
Methyl nicotinate has a fresh, sweet, caramellic nutty odor.
9.10 Chemical Properties
Methyl nicotinate has a fresh, caramellic, nutty and mild tobacco odor.
9.11 Chemical Properties
white to brownish crystals or crystalline powder
9.12 Occurrence
Reported found in ground coffee, roasted filberts, guanabana (Annona muicata L.), roasted peanuts, wild strawberries, vanilla bean, papaya, guava, plum, beer cognac, soursop, malt, wort, Bourbon vanilla and mountain papaya.
9.13 Uses
Methyl nicotinate can be employed as a precursor in the synthesis:
  • Di-3-pyridyl ketone ligand, which is used in the preparation of silver(I) complexes for the derivation of coordination polymeric chains.
  • 5-arylnicotinates , ±-sesbanine , and 1,4-dihydropyridine derivatives.
