摘要:
Leukotrienes B 4 , C 4 , D 4 and E 4 are conjugated with various proteins, viz. Bovine Serum Albumin, Hemocyanin from Giant Keyhole Limpets, human serum albumin, tetanus antigen, diphtheriae toxoid and CRM 197 using 1,5-difluoro-2,4-dinitrobenzene or 6-N-maleimido(C 2-8 alkanoic acid)-chloride as coupling agent. These conjugates are useful as reagents in a newly developed immunoassay for leukotrienes, as well as having potential utility as chemical immunotherapeutic agents in the treatment of various allergic and chronic inflammatory diseases of the skin, lung, and airways, including asthma, allergic rhinitis, rheumatoid arthritis, and skin diseases such as psoriasis and eczema. They may be made into pharmaceutical compositions. Certain novel intermediate compounds are also provided.

摘要:
The present invention relates to a stereoselective synthesis of leukotriene antagonists. More particularly, this invention relates to the stereoselective synthesis of (βS,γR) and (βR,γS)-4-((3-(4-acetyl-3-hydroxy-2-propyl(phenoxy)propyl)thio)-γ-hydroxy-β-methylbenzenebutanoic acid, and related compounds. These compounds are useful therapeutic agents for treating allergic conditions, asthma, cardiovascular disorders, inflammation and pain in mammals, especially humans. The compounds are also useful for inducing cytoprotection in mammals, especially humans.
