Disclaimer

• This presentation describes applications developed on Agilent 6890/5973 GC/MS system and Agilent 1100 Series LC/MSD.

• Agilent Technologies provided no financial support for this project.

Smart Drugs

• Nootropics

• Stimulants but alleged to boost brain function and cognition

• Uses:

– Alzheimer’s disease

– Parkinson’s disease

– ADHD

– “Academic doping”

Smart Drugs

• Pharmacokinetics

– Oral administration

– Rapid absorption

– Half life: 1-6 hours

• Pharmacodynamics??

– Increases adrenergic, dopaminergic, and histaminergic activity in the brain

– Inhibit the release of γ-aminobutyric acid (GABA)

Abuse Potential

• Enhances

– Focus

– Memory

– Vigilance

– Attention

• Increases drive and motivation

• Does not cause restlessness and involuntary motor movements

Drugs of Interest

Piracetam Pramiracetam Aniracetam

Noopept Ciproxifan

11

Drugs of Interest

Modafinil Adrafinil

12

Research Objectives

• Development of a single analytical method for the detection and quantification of smart drugs in blood, urine, and pill/powder products

• Validation of the assay for the analysis of unknown samples

13

Gas Chromatography/Mass Spectrometry (GC/MS)

• Agilent 6890/5973 GC/MS system

14

Liquid Chromatography/Mass Spectrometry (LC/MS)

• Agilent 1100 Series LC/MSD
