Determination of Idebenone in Plasma by HPLC with Post-Column Fluorescence Derivatization Using 2-Cyanoacetamide
Idebenone is a benzoquinone analog that is used in the treatment of several neurological disorders including Friedreich’s ataxia. It was found that the reaction of idebenone with 2-cyanoacetamide under alkaline conditions generates fluorescent products, and the reaction was considered to proceed via Craven’s reaction. The reaction mixture from idebenone gave fluorescence with excitation and emission maximum wavelengths at 358 nm and 409 nm, respectively. It was adopted for HPLC with post-column fluorescence derivatization of idebenone. Idebenone in the plasma showed a linear response in the range of 0.5–32 ng (25–1600 ng/mL), and the quantitation limit (S/N=10) was 12.5 ng/mL. The detection limit (S/N=3) of the standard solution of idebenone was 0.1 ng. The HPLC system was applied to the human blood plasma obtained by finger prick. The plasma sample obtained by finger prick gave a similar chromatogram to that of venous blood obtained by venipuncture.

oxydecyl)-1,4-benzoquinone] is a synthetic analogue of coenzymeQ that is currently employed in the treatment of vascular and degenerative diseases of the central nervous system. There is some evidence to suggest that idebenone might function as an antioxidant; however, it has not been demonstrated whether this function pertains to the quinone or hydroquinone form of idebenone. Here we demonstrate
