|Title:||Certain 4-phenoxy(or phenylthio)-3-n-acylated-sulfonamido-pyridines|
|Abstract:||This invention relates to new derivatives of pyridine having hypo-uricemic or hypolipemic properties. The new derivatives of pyridine may be represented by the following general formula: ##STR1## in which X represents an oxy or thio group, R.sub.1 represents hydrogen, a group of the formula R.sub.3 NHCO (II), wherein R.sub.3 represents a C.sub.1 -C.sub.4 -alkyl, cycloalkyl or possibly substituted phenyl group, or a group of the formula R.sub.4 --CO (III) in which R.sub.4 represents a C.sub.1- C.sub.4 -alkyl group or a possibly substituted phenyl group, and R', R" and R'" represent each a possible substituent selected from the group comprising the halogens, the trifluoromethyl and the C.sub.1- C.sub.4 alkyl groups.|
|Inventor(s):||Delarge; Jacques E. (Dolembreux, BE), Lapiere; Charles L. (Tongeren, BE), Georges; Andre H. (Ottignies, BE)|
|Assignee:||A. Christiaens Societe Anonyme (Brussels, BE)|
|Filing Date:||Jun 09, 1976|
|Claims:||1. A compound of the following structure: ##STR8## in which X represents an oxy or thio group; R.sub.1 represetns a group of the formula: ##STR9## wherein R.sub.3 represents a C.sub.1 -C.sub.4 -alkyl, cyclohexyl, unsubstituted phenyl or substituted phenyl group, or R.sub.1 represents a group of the formula: |
wherein R.sub.4 represents a C.sub.1 -C.sub.4 -alkyl group or an unsubstituted or substituted phenyl group; R', R" and R'" represent each hydrogen or a substituent selected from the group comprising the halogen atoms, the trifluoromethyl group and the C.sub.1 -C.sub.4 -alkyl groups, as well as the pyridine N-oxide of the compounds of Formula I and the pharmaceutically acceptable base and acid addition salts of said compounds.
2. A compound according to claim 1, in which X is a thio group, R.sub.1 is acetyl, propionyl, parachlorobenzoyl or a R.sub.3 -carbamyl group, and one of the symbols R', R" and R'" represent 3-methyl or one or two of the symbols R', R", and R'" represent chlorine, the other being hydrogen.
3. A compound according to claim 1, in which X is a thio group, R.sub.1 is acetyl, propionyl, para-chlorobenzoyl or a R.sub.3 -carbamyl group, and one of the symbols R', R" and R'" represent 3-trifluoromethyl or 4-methyl, the others being hydrogen.
4. 4-(3'-chlorophenoxy)-3-R.sub.3 -carbamylsulfonamidopyridines according to claim 1.
6. Pharmaceutical compositions containing a hypo-uricemic or hypo-lipemic effective amount of at least one compound according to claim 1 as active ingredient, together with a pharmaceutical carrier or vehicle.
