Abstract

We developed a highly sensitive and specific method for the simultaneous quantitation of leukotriene B₄ (LTB₄) and its ω-oxidized metabolites (20-hydroxy-LTB₄ and 20-carboxy-LTB₄) by mass fragmentography using deuterated compounds as internal standards. The ions produced by the cleavage of the C12-13 bond of the methyl ester dimethylisopropylsilyl ether derivatives of LTB₄ and its metabolites were measured by selective ion monitorings. The detection limit of LTB₄ was less than 10 pg and about 100-fold lower than that by high performance liquid chromatography. By using this method, the synthesis and further metabolism of LTB₄ in human polymorphonuclear leukocytes were investigated.
