Journal of pharmaceutical and biomedical analysis, 19(6), 855-864 (2000-03-04)
Two tyrosine specific, HPLC methods with either electrochemical (HPLC-ED) or fluorescence (HPLC-FL) detection are described for leucine-enkephalin (LE) in cerebrospinal fluid (CSF). Both approaches involve the hydroxylation of the Tyr1-moiety of LE by mushroom tyrosinase. Production of a catechol permitted

A new tyrosine-specific LC assay with pre-column fluorogenic derivatization is described for Tyr-Gly as model peptide. o-Hydroxylation of the tyrosine residue with tyrosinase in the presence of ascorbic acid, followed by oxidation to the corresponding quinone by potassium ferricyanide at

Fast and efficient baseline separation of asymmetrically substituted diarylmethanols and 1,1-diarylethanols was achieved on an endcapped, amide-linked N-3,5-dinitrobenzoylated, (R,R)-1,2-diphenyl-1,2-ethanediamine-derived chiral stationary phase (CSP). Optimal enantioselectivities on this CSP were obtained using 1% 2-propanol in n-heptane as the mobile phase. Enantiorecognition

We resolved 1,2-diphenylethylamine (DPEA) into its (S)- and (R)-enantiomer and used them as precursors for synthesis of (S)- and (R)-1-(1,2-diphenylethyl)piperidine, flexible homeomorphs of the NMDA channel blocker MK-801. We also describe the synthesis of the dicyclohexyl analogues of DPEA. These

The widely used anticoagulant Coumadin (R/S-warfarin) undergoes oxidation by cytochromes P450 into hydroxywarfarins that subsequently become conjugated for excretion in urine. Hydroxywarfarins may modulate warfarin metabolism transcriptionally or through direct inhibition of cytochromes P450 and thus, UGT action toward hydroxywarfarin
