inhibitors derived from the structures of the substrates involved in the methylationreaction. By covalently linking fragments of the NNMT substrates a diverse library of bisubstrate-like compounds was prepared. The ability of these compounds to inhibit NNMT was evaluated providing valuable insights into the structural tolerances of the enzyme active site. These studies led to the identification of new

Compounds of the formula I:
and their pharmaceutically acceptable salts are leukotriene antagonists. These compounds inhibit SRS-A and leukotriene synthesis and are antagonists of SRS-A and are thus useful in the treatment of asthma, allergic disorders, inflammation, skin diseases and certain cardiovascular disorders. For this purpose they are made into pharmaceutical composition.
In the formula, and B are hydrogen or certain rings, X is O, S, SO, or SO2; Y is H, OH, =0, or OR2; n is 0,1 or 2;a,b and c are 0 to 5; R' is one of CH2OH, CHO, tetrazolyl, CN, certain phenolic heterocycles, certain esterfied carboxyls, hydroxymethyl ketone, and certain substituted carbamoyl and sul- fonylamino groups: and R2 and R' are H oralkyl orform a ring.

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.
