- 1,2-DIHYDRO-4-HYDROXY-2-OXO-QUINOLINE-3-CARBOXANILIDES AS AHR ACTIVATORS.
-
The present invention relates to compounds which are 1, 2-dihydro-4- hydroxy-2-oxo-quinoline-3-carboxanilides, their thieno-pyridone analogs, and prodrugs thereof. This invention specifically relates to such derivatives containing an N-hydrogen in the carboxanilide moiety and which exhibit modulating activity towards the aromatic hydrocarbon receptor (AhR), and, specifically, also to prodrugs thereof. The present invention also relates to use of said compounds as a medicament, and for the treatment of cancer, autoimmune disorders and other disorders with an immunological component, and a pharmaceutical composition comprising one or more of said compounds and a method of treatment.

- METHOD FOR MANUFACTURING OF QUINOLINE-3-CARBOXAMIDES
-
A method for preparing a compound of formula (I) by reacting the appropriate alkyl ester and an aniline derivative, in a refluxing mixture containing an aliphatic solvent or a mixture of aliphatic solvents having a boiling point in the range of 68-191 °C; condensing vapors of the refluxing mixture; treating the condensed vapors with an alcohol scavenging agent or a mixture of alcohol scavenging agents; and returning the condensed vapors back to the reaction mixture.

- Synthesis and Biological Evaluation of New 1,2-Dihydro-4-hydroxy-2-oxo-3-quinolinecarboxamides for Treatment of Autoimmune Disorders: Structure-Activity Relationship
-
Roquinimex-related 3-quinolinecarboxamide derivatives were prepared and evaluated for treatment of autoimmune disorders. The compounds were tested in mice for their inhibitory effects on disease development in the acute experimental autoimmune encephalomyelitis model and selected compounds in the beagle dog for induction of proinflammatory reaction. Structure-activity relationships are discussed. Compound 8c, laquinimod, showed improved potency and superior toxicological profile compared to the lead compound roquinimex (1b, Linomide) and was selected for clinical studies (currently in phase II).

- Quinoline derivatives
-
The invention relates to compounds of general formula (I) wherein R is selected from ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and allyl; R4 is selected from hydrogen and pharmaceutically acceptable inorganic and organic cations; R5 is selected from methyl, ethyl, n-propyl, iso-propyl, methoxy, ethoxy, chloro, bromo, CF3, and OCHxFy; wherein x=0-2, y=1-3 with the proviso that x+y=3; R6 is hydrogen; or R5 and R6 taken together are methylenedioxy; and any tautomer hereof. The invention also relates to pharmaceutical compositions containing a compound of the general formula (I) together with a pharmaceutically acceptable carrier. Included are also processes for the preparation of the compounds of formula (I), as well as methods of treating mammals suffering from diseases resulting from autoimmunity and pathological inflammation by administering a compound having the formula (I) to said mammal.
