摘要:
The present invention provides for certain sulfonyl ureas and related compounds which have advantageous properties and show useful activity in the inhibition of activation of the NLRP3 inflammasome. Such compounds are useful in the treatment of a wide range of disorders in which the inflammation process, or more specifically the NLRP3 inflammasome, have been implicated as being a key factor.
摘要:
Provided are solid forms of 5-(halomethyl)furfural, including a crystalline form of 5- (chloromethyl)furfural. Provided are also methods for preparing solid forms of 5- (halomethyl)furfural by crystallization using certain solvents.
摘要:
Methods are described for the preparation of combinatorial libraries of potentially biologically active disaccharide compounds. These compounds are variously functionalized, with a view to varying lipid solubility size, function and other properties, with the particular aim of discovering novel drug or drug-like compounds, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of disaccharides, variously functionalised about the sugar ring, including the addition of aromaticity and charge, and the placement of pharmaceutically useful groups and isosteres.
摘要:
The disclosure relates to compounds of formula (I) and pharmaceutically acceptable addition salts thereof wherein X represents a single, direct bond or a substituted or unsubstituted alkylene chain containing 1 to 4 carbon atoms, wherein R5 is a lower alkyl group, wherein R6 is either hydrogen or methyl, wherein Am is selected from the class consisting of amino, lower mono and dialkylamino, piperidino, piperazino, N-lower alkyl piperazino, pyrrrolidino, and morpholino groups wherein Y1 and Y2 are identical and are hydrogen, a halogen, methyl or ethyl and n is an integer in the range of 1-5. They are useful in treating arrhythmic conditions and conditions for which treatment with a vasodilator is indicated.
