A thermosetting composition including an organic solvent, a liquid crystalline thermoset oligomer, and either a crosslinking agent or an epoxy resin or both is disclosed. A printed circuit board which includes the thermosetting composition is also disclosed. The printed circuit board is produced by impregnating the thermosetting composition into a reinforcing material.

The synthesis, characterization and biological evaluation of a library of isoindoline-1,3-dione-based oximes and benzenesulfonamide hydrazones is disclosed. The set of hydroxyiminoethyl aromatic derivatives 10–18 was designed to assess the potentiality as zinc-binder for a feebly studied functional group in the field of carbonic anhydrase (CA, EC 4.2.1.1) inhibition. Analogue phenylphthalimmides were
