7Z)-6-S-glutathionyl-5-hydroxy-9-(4-heptanylphenyl)-7 -nonenoic acid. This analogue has an EC50 value of 74.5 nM, in the presence of 1-serine borate (45 mM), on guinea pig tracheal spirals. The agonist activity of the cysteinylglycinyl- and the cysteinyl-substituted analogues was inhibited by FPL-55712. Three of the analogues were weak leukotriene antagonists in vitro on guinea pig tracheal spirals. The most potent
Chemical modification in the hydrophilic and hydrophobic regions of leukotrienes was investigated in relation to their smooth muscle contractile activities. The conjugated diene or triene moiety in the hydrophobic region is crucial for potent contractile activity. The hydrophilic region at the C-6 position is not dependent only on amino acid or peptide for potent contractile activity ; some heterocyclic compounds can be used instead.

6-Epi-leukotrienes C and D (3 and 4) have been synthesized unambiguously via the 5(S), 6(R)-epoxide (5,6-cis) which is isomeric with leukotriene A. These 6-epi-leukotrienes are less active (especially 4) than leukotrienes C and D (1 and 2) and have not been found in substantial quantity in natural SRS sources.
