There is provided (i) a method of analysing small molecules that may have a mass of <800 Da, in particular alkaloids, said method being generally referred to as MALDI-TOF-MS (or MALDI time-of-flight mass spectrometry), which is an acronym for a method of analysis by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry. Also provided is (ii) a molecule according to formula (I) and the use of the molecule as a matrix in the analysis method.
The present invention relates to compounds that have the ability to modulate the activity of GPR40 and are therefore useful in the treatment of GPR40 related disorders. In addition the invention relates to the compounds, methods for their preparation, pharmaceutical compositions containing the compounds and the uses of these compounds in the treatment of certain disorders related to GPR40 activity.

A new Pd/MgLa mixed oxide and the known Pd/MgAl hydrotalcite catalysts were applied and recycled successfully in catalytic transfer hydrogenation reactions in ionic liquids. Some alpha,beta-unsaturated carboxylic acid derivatives were hydrogenated in excellent yields. The catalysts were recycled without significant loss of activity. Besides that, a number of halogenated aromatic compounds were dehalogenated under similar catalytic transfer conditions.
