C-20 Trideuterated leukotriene A4 methyl ester was prepared by Wittig condensation of a deuterated C9-phosphonium salt with a C11-epoxydienal. It was then treated separately with glutathione, cysteinylglycine and cysteine. The resulting esters were saponified to give C-20 trideuterated leukotrienes C4

Six major basic cytosolic glutathione transferases from rat liver catalyzed the conversion of leukotriene A4 methyl ester to the corresponding leukotriene C4 monomethyl ester. Glutathione transferase 4-4, the most active among these enzymes, had a Vmax of 615 nmol X

Biochemistry international, 15(6), 1127-1135 (1987-12-01)
It has been shown that various glutathione transferases can synthesize leukotriene C4, or its methyl ester, from glutathione and leukotriene A4. We questioned whether the same enzymes could be used to resolve racemic leukotriene A4 methyl ester (more easily prepared

The strategy of acyclic eicosanoid synthesis via polyacetylenic intermediates is examplified by the synthesis of the racemic leukotriene A4 methyl ester. Leukotriene synthons, namely, trideca-1,4,7-triyne and methyl 6-formyl-5,6-trans-epoxyhexanoate, were synthesised using propargylic alcohol (thrice) and 1-heptyne as starting materials. In
