摘要:
Disclosed embodiments concern the synthesis and use of therapeutic compounds that for treating emerging flu strains and minimizing resistance to such strains. Methods for making the disclosed compounds concern using a base-mediated addition/cyclization sequence followed by functional group manipulation to develop functionalized compounds that can target neuraminidase, which makes them ideal candidates for treating influenza. Pharmaceutical compositions comprising the therapeutic compounds and biologically-acceptable materials are also described. Methods of inhibiting neuraminidase in subjects that are suspected of containing neuraminidase are also described. The use of metabolites of the disclosed compounds can also be used in diagnostic assays for therapeutic dosing of the disclosed compounds.
摘要:
Production of unsaturated ketones by the aldol condensation of ketones such as acetone or methyl ethyl ketone by contacting the ketone in the vapor phase with a particulate catalyst comprising at least one basic alkali metal compound supported on an inert substrate at a temperature above 175° C. The produce ketones may be hydrogenated to form saturated ketones or alcohols.
