Abstract:
PROBLEM TO BE SOLVED: To obtain a medicine to be efficacious in the treatment of T-helper cell type 2 (Th2)-mediated immune diseases such as immunoglobulin E (IgE)-mediated allergic diseases. SOLUTION: The medicine composition comprises retinoids with retinoid receptor antagonistic activity called retinoid antagonists, pharmaceutically acceptable salts and pharmaceutically acceptable hydrolyzable esters thereof, concretely, for example, p-[(E)-2-[3',4'-dihydro-4',4'-dimethyl-7'(heptyloxy)-2'H-1-benzothiopyran-6'-yl]propenyl]benzoic acid 1,1'-dioxide.

Abstract:
PROBLEM TO BE SOLVED: To obtain a medicine effective for diseases and allergic diseases related to imunoglobulin E (IgE) and mast cells due to the expression and activation of allergen-specific Th 2 cells, such as atopic dermatitis, other skin diseases related to the atopic dermatitis, allergic rhinitis or hay fever, mild or serious, acute or chronic allergic bronchial asthma accompanied or not accompanied by acute or chronic bronchitis, high imunoglobulin E (IgE) serum concentration, and eosinophilia. SOLUTION: A retinoid receptor-antagonizing activity-having retinoid called a retinoid antagonist, its pharmaceutically acceptable salt, and its pharmaceutically acceptable hydrolysable ester is effective for treating type II helper T cell (Th2)-mediated immune diseases, such as imunoglobulin E (IgE)-mediated allergic diseases.

Abstract:
PROBLEM TO BE SOLVED: To provide a medicament containing a receptor agonist useful for treating emphysema and other diseases associated with pulmonary alveolar damage. SOLUTION: A retinoic acid receptor (RAR) agonist, especially an RARγ receptor-selective agonist which is selective to an RARγ receptor and has a selectivity of the RARγ receptor at least 20 times compared with RARα and RARβ receptors, is effective for treating emphysema and other diseases associated with pulmonary alveolar damage. The medicament contains one or more kinds of the above agonist. As the agonist, a compound represented by formula VII is especially excellent. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:

In the formula, n=1 or 2; Z= -SO3-M+, - SO2-M+, ower alkylthio, lower alkylsulfinyl(or sulfonyl); M+= cation; A=triarylphosphonium ethyl of formula H3C-CH-P[Q3 +Y- or acetyl; B=formyl or dialkoxyphosphonyl methyl of formula-CH2-P(=0) [T 2; Q=aryl, T=lower alkoxy, Y-=anion of inorg. or org. acids.
Abstract:
PROBLEM TO BE SOLVED: To obtain a new compound which is useful for treatment of epithelial lesions, for example, acne, psoriasis, and of dermatopathy accompanied by inflammation and for treatment and prevention of tumors and precancerous change in oral cavity, tongue, pharynx, esophagus, bladder, neck and colonic mucous membrane. SOLUTION: This new compound is represented by formula I [X is oxo in 4-, 5-position, OR (R is H, an alkyl, an acyl); dotted line can be arbitrarily present and a double bond is present between 3- and 4-positions only in the case that X is present on 5-position], typically (2Z,4E,6E,8E)-(R)-9-(4-hydroxy-2,6,6- trimethyl-cyclohex-1-enyl)-3,7-dimethyl-nona-2,4,6,8-tetraenoic acid. The compound of formula I is prepared by reaction of a compound of formula II [A is a (substituted) phenyl; Y is an anion] with 5-hydroxy-4-methyl-5H-furan-2-one in the presence of a base followed by isomerization of the C=C double bond formed in the preceding reaction from the cis to the trans form.
