The invention provides compounds of formula I [INSERT CHEMICAL STRUCTURE HERE] (I) and pharmaceutically acceptable salts thereof. The formula I thiazolyl compounds inhibit tyrosine kinase activity thereby making them useful as anticancer agents and for the treatment of Alzheimer's Disease.
Synthesis of Bioactive 3,4-Dihydro-2<i>H</i>-naphtho[2,3-<i>b</i>][1,4]oxazine-5,10-dione and 2,3,4,5-Tetrahydro-1<i>H</i>-naphtho[2,3-<i>b</i>]azepine-6,11-dione Derivatives via the Copper-Catalyzed Intramolecular Coupling Reaction
A convenient synthesis of 3,4-dihydro-2H-naphtho[2,3-b][1,4]oxazine-5,10-diones and 2,3,4,5-tetrahydro-1H-naphtho[2,3-b]azepine-6,11-diones via the copper-catalyzed intramolecular C–O/C–C coupling reaction is described. This method showed a good tolerance for functional groups and was applied to the synthesis of natural product core structures. Some coupling products exhibited moderate activities against

The present invention relates to novel HPLC methods for the analysis of the API formoterol and related substances. In a first method the mobile phase comprises two or more liquids, and the relative concentration of the liquids is varied to a predetermined gradient. In a second method the mobile phase comprises a first liquid A comprising an aqueous solution of ammonium acetate and a second liquid B comprising a dipolar aprotic solvent. In a third method the mobile phase comprises a first liquid A comprising an aqueous solution of ammonium acetate with a concentration of 0.001 to 0.025M, and a second liquid B. The present invention also relates to a method for analysing a substance, comprising the detection and optional quantification of one or more specific impurities.
