Common Name | 3-(4-Hydroxy-3-methoxyphenyl)-2-methyllactic acid |
---|
Description | 3-(4-Hydroxy-3-methoxyphenyl)-2-methyllactic acid belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid. 3-(4-Hydroxy-3-methoxyphenyl)-2-methyllactic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). This property is significant in that it allows a greater proportion of peripheral levodopa to cross the blood brain barrier for central nervous system effect. Carbidopa (Lodosyn) is a drug given to people with Parkinson's disease in order to inhibit peripheral metabolism of levodopa. 3-(4-Hydroxy-3-methoxyphenyl)-2-methyllactic acid is a metabolite of carbidopa. |
