An hplc method is described which determines debrisoquine and its metabolite, 4-hydroxydebrisoquine, quantitatively after conversion of the guanidine moieties into the corresponding pyrimidines. Sensitivity, precision, and accuracy have been sufficient enough for the reliable hydroxylation phenotyping of 145 non-related healthy volunteers (64 males, 81 females, 31-80 years). 17 (11%) were poor metabolizers of debrisoquine (gene frequency: 34.2%).

D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction

D003647 Debrisoquin An adrenergic neuron-blocking drug similar in effects to GUANETHIDINE. It is also noteworthy in being a substrate for a polymorphic cytochrome P-450 enzyme. Persons with certain isoforms of this enzyme are unable to properly metabolize this and many other clinically important drugs. They are commonly referred to as having a debrisoquin 4-hydroxylase polymorphism. Debrisoquine,Tendor
