摘要:
The present invention provides low molecular weight compounds useful as cytokine inhibitors, and compositions thereof. In particular, compounds of the invention are useful as anti-inflammatory agents. There are further provided methods for the preparation of such agents and their use in preventing or treating conditions mediated by cytokines such as arthritis.
摘要:
One aspect of the present invention relates to ionic liquids comprising a pendant Bronsted-acid group, e.g., a sulfonic acid group. Another aspect of the present invention relates to the use of an ionic liquid comprising a pendant Bronsted-acidic group to catalyze a Bronsted-acid catalyzed chemical reaction. A third aspect of the present invention relates to ionic liquids comprising a pendant nucleophilic group, e.g., an amine. Still another aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to catalyze a nucleophile-assisted chemical reaction. A fifth aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to remove a gaseous impurity, e.g., carbon dioxide, from a gas, e.g., sour natural gas.
摘要:
The invention relates to compounds of formula (I), in which R1, R2, R3, R4, X and Y are defined as cited in the description. The compounds have an immune-modulating action and inhibit or regulate the release of IL-1β and/or TNF-α. They can therefore be used to treat diseases that involve disorders of the immune system.
