Study Notes
Bioprecursor Prodrugs
- Bioprecursor prodrugs are inactive molecules that are converted into active drugs in the body.
- An example is L-Dopa, which is converted to dopamine in the brain.
- L-Dopa is used to treat Parkinson's disease.
- Dopamine does not cross the blood-brain barrier efficiently.
- Dopamine is rapidly metabolized by oxidative deamination.
- Dopamine can cause peripheral side effects.
Chemical Delivery Systems
- Pro-2-PAM is a dihydropyridine derivative that is a prodrug of 2-PAM.
- Pro-2-PAM undergoes metabolic and chemical oxidation to yield the active drug 2-PAM.
- The amide hydrolysis step of Pro-2-PAM may be slower than the dihydropyridine oxidation step.
- This creates a reservoir of pyridinium amide precursor which is available for conversion to the active drug species.
