Substituted phenidates (also known as phenidates) refer to a class of compounds that predominantly produce traditional stimulant effects when administered. A substituted phenidate may be defined as an ester of ritalinic acid and its analogs.
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 Rα position that links to the RN position, forming a piperidine ring. It also includes a substitution at the Rβ position of methyl acetate.
Substituted phenidates primarily act as reuptake inhibitors of the monoamine neurotransmitters dopamine, norepinephrine, and to a much lesser degree, serotonin. One study found that all substituted phenidates inhibited the norepinephrine and dopamine reuptake transporters 4 to >1,000-fold more potently than the serotonin transporter.
