Substituted phenidates

Generic structure of a phenidate molecule.

Substituted phenidates (also known as phenidates) are a class of chemicals that include compounds that typically produce traditional stimulant effects. Pharmacologically, they tend to act as reuptake inhibitors of the monoamine neurotransmitters dopamine and norepinephrine, and occasionally serotonin.

Chemistry

Substituted phenidates are a chemical class based upon the molecule methylphenidate. The molecular structure of methylphenidate is comprised of a phenethylamine core with a carbon chain substitution at the R_α position that links to the R_N position, forming a piperidine ring. It also includes a substitution at the R_β position of methyl acetate.
