    Abstract:
    The synthesis and biological characterization of a series of novel leukotriene antagonists and agonists are reported. All of these compounds are derivatives of (5S,6R,7Z)-5-hydroxy-6-mercapto-9-phenyl-7-nonenoic acid. One of the more potent compounds is (5S,6R,7Z)-6-[[(4-carboxy-2-methoxyphenyl)methyl]thio]-5-hydroxy-9 -(4- heptylphenyl)-7-nonenoic acid (3f). In vitro evaluation of this compound on guinea pig trachea revealed that it is a competitive antagonist of LTD4 and LTE4 with pKB values of 6.4 and 5.8, respectively. On guinea pig ileum, the pKB values obtained for it with LTD4 and E4 were both 7.2. The selectivity of 3f was shown by its lack of effect on carbachol, histamine, and barium chloride concentration-response curves in guinea pig trachea.
