摘要:
Compounds having the structural formula: are disclosed wherein there are 0-4 R groups and
R is e.g. hydrogen, lower alkyl, halo-loweralkyl, hydroxy, lower alkoxy, halo, lower alkylthio or lower alkylsulfinyl; R 1 is e.g. hydrogen or lower alkyl;
Z is (a) -(CH 2 ) o-n , n being 0-10; (b) -CO(CH 2 ) 1-n -; (c) -(CH 2 ) 1-n -CO-; or (d)
R 2 is e.g. hydrogen or lower alkyl; R 3 is hydrogen, lower alkyl, hydroxy, loveralkoxy or halo; and X-Y is e.g. -O-CH 2 - or -S-CH 2 -.
Those compounds have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.
摘要:
Aryl substituted thiophenes 3-ols, its dihydro derivatives, 1-oxide and 1,1-dioxide analogs, as well as aryl substituted furans, are 5-lipoxygenase inhibitors useful in the treatment of inflammation and other leukotriene-mediated diseases.
摘要:
Zomepirac and its analogs of the structural formula: wherein
Ar is phenyl or halophenyl; R 1 and R 3 independently are H or C 1-6 alkyl and R 2 is H, C 1-6 alkyl or halo are prepared from a 5-aroyl-3-hydroxycarbonyl-4-substituted pyrrole-2-acetic acid via acidic decarboxylation.

摘要:
N-Alkenyl-3-hydroxybenzo [b] thiophene-2-carboxamide derivatives of formula) and their pharmaceutically acceptable salts, are novel. In the formula, each of R, R 1 , R 2 , R 3 and R 4 is selected from various hydrocarbons (including heteroaryl), acyl, and acyl- substituted hydrocarbon groups and their ring-substituted derivatives; or R 1 , R 2 and R 3 can be halo, or R' and R 2 joined to form certain tricyclic bivalent residues, or R 4 is -CR 1 =CR 2 R 3 , and n is 0, 1, or 2. These compounds are prepared by (1) treating a substituted 2-halobenzoate with thioacetamide followed by N-alkenylation with appropriate agents, such as aldehydes, ketones, enol ethers, epoxides, acetals or ketals; (2) treating a substituted thiosalicylate with an appropriately substituted halocetamide, followed by dehydration; and (3) further synthetic modification of compounds prepared above. These compounds have been found to be effective inhibitors of both cyclooxygenase and lipoxygenase and thereby useful in the treatment of pain, fever, inflammation, arthritic conditions, asthma, allergic disorders, skin diseases, cardiovascular disorders, psoriasis, inflammatory bowel disease, glaucoma or other prostaglandins and/or leukotriene mediated diseases. Furthermore, these compounds have been found to exhibit cytoprotective activity which does not involve the inhibition of gastric acid secretion but can be used as relatively low dosages for increasing the resistance of gastro-intestinal mucosa to strong irritants. They are included in pharmaceutical compositions.
