Ritalinic Acid Immunoassay . United States Patent Application 20140242618 . Kind Code: A1 . Abstract: The invention provides novel antibodies which specifically bind to the methylphenidate metabolite, ritalinic acid, enabling an immunoassay that can detect methyphenidate in biological samples for an extended period following its ingestion. The invention also describes novel conjugates and kits. (±)-Threo-2-Phenyl-2-(piperidin-2-yl)acetic acid ((±)-threo-ritalinic acid, (±)-threo-2): Method A : 1 At ambient temperature, open to air one neck round bottom flask was charged with methyl 2-phenyl-2-(piperidin-2-yl)acetate (methylphenidate, 100 mg, 0.42 mmol) an Synthesis of ±-threo-Ritalinic acid-D 10 HCl Based on literature precedence 1-3, ±-threo-Ritalinic acid-D 10 HCl was synthesized in seven steps from pyridine-D 5. During the synthesis, the crucial reduction of the pyridine moiety to the fully deuterated piperidine proceeded in good yield but LC/MSSIM indicated that the product yp Ritalinic acid is a major metabolite of and synthetic precursor to methylphenidate and may be monitored clinically and forensically. The synthesis of deuterated ±-threo-ritalinic acid was therefore undertaken to develop an analytical reference standard and as a precursor to deuterated ±-threo-methylphenidate

Ritalinic acid is an inactive major metabolite of the psychostimulant drug methylphenidate. When administered orally methylphenidate is extensively metabolized in the liver by hydrolysis of the ester group yielding ritalinic acid. The hydrolysis was found to be catalyzed by carboxylesterase 1 (CES1). thumbnail ATC prefix None CAS number 19395-41-6 IUPAC name 2-phenyl-2-piperidin-2-ylacetic.

Malonic Ester Synthesis. Malonic esters are more acidic than simple esters, so that alkylations can be carried out via enolate formation promoted by relatively mild bases such as sodium alkoxide, and subsequent alkylation with halides. An excess of ester must be used to prevent dialkylated products. Carboxylic acids may optionally be obtained after hydrolysis and decarboxylation. Ritalinic acid is a substituted phenethylamine and an inactive major metabolite of the psychostimulant drugs methylphenidate and ethylphenidate.
