This research has presented a solution to the problem faced by alloys: corrosion problem, reducing and enhancing protection using an inhibitor (Schiff base). The base) was synthesized reacting of substrates materials (4-dimethylaminobenzaldehyde 4-aminoantipyrine). It diagnosed infrared technology IR, where IR spectrum through visible beams proved that Schiff base well formed with high purity. ...

Dipyrone (Dp) delays gastric emptying (GE) in rats. There is no information about whether 4-aminoantipyrine (AA), one of its metabolites, has the same effect. The objectives of the present study were to assess the effects of AA and Dp on GE when administered intravenously (iv) and intracerebroventricularly (icv) (240 micromol/kg and 4 micromol/animal, respectively) and on gastric compliance whe...

Novel copper(II) complexes have been synthesized from the macrocyclic Schiff bases derived from Knoevenagel condensed β-ketoanilides (obtained by the condensation of acetoacetanilide and substituted benzaldehydes), 4-aminoantipyrine and o-phenylene diamine. The structural features have been determined from their analytical and spectral data. All the Cu(II) complexes exhibit square planar geomet...
