Prevention or therapy of inflammatory diseases caused by invasion of leukocytes such as monocytes, lymphocytes and eosinophils, by providing a substance which inhibits cell adhesion via an adhesion molecule, especially adhesion molecule VLA-4, is disclosed. A group of carboxylic acid derivatives represented by, for example,
and adhesion molecule inhibitors comprising the same as an effective ingredient were provided.
The first synthesis of (±)-harzianopyridone, an antifungalmetabolite of Trichodermaharzianum, has been achieved by metalation of 6-substituted-2,3-dimethoxy-4-pyridyl-N,N-diisopropylcarbamates. Moreover, the chosen strategy allowed the preparation of harzianopyridone analogs, by varying the groups at C-4, C-5 and C-6 on the pyridine ring.

[reaction: see text] The relative and absoluteconfiguration of the pneumocandin B(0) sidechain has been established as (10R,12S)-dimethylmyristoyl by the stereocontrolled synthesis of both antipodes of the sidechain acid and their comparison to a sample derived from the natural product.
(-)-Atpenin B (1) is an antibiotic produced by Penicillium sp. FO-125. The first synthesis of 2,4-dihydroxy-5,6-dimethoxy-3-((2RS,4RS)-2;4-dimethyl-1-oxohexyl)pyridine (atpenin B) (16) is reported. This molecule, which exhibits a pentasubstituted pyridine structure, was prepared from 2-chloropyridine in 13 steps, by metalating and then functionalizing, one after another, all the remaining positions of the pyridine ring. The methodology involves four metalation steps (including metalation of 2,3-dimethoxypyridine and pyridyl N,N-diisopropylcarbamates), one halogen-scrambling step, and one bromine-lithium exchange step.
