Pharmacophoric comparison between papaverine and tofisopam led to identify three new series of microto sub-micromolar inhibitors of phosphodiesterase-4, including 7,8-dialkoxy-2,3-benzodiazepin-4-one derivatives, 7,8-dialkoxy-1,4- benzodiazepin-2-one derivatives, and dialkoxybenzophenone derivatives.

The stable and non-hygroscopic aluminum dodecatungstophosphate (AlPW12O40), was found to be an effective catalyst (3 mol%) for the solvent-free Friedel-Crafts acylation of aromatic compounds with carboxylic acids in the presence of trifluoroacetic anhydride under mild reaction conditions.
