In order to improve the antibacterial activity of ampicillin, new penicillin derivatives having a 1-aryltriazole-4-carboxamide group or a 5-arylisoxazole-3-carboxamide group at the alpha-position of benzylpenicillin or p-hydroxybenzylpenicillin were synthesized. Some compounds in these series were found to possess high activity against Pseudomonas and other Gram-negative bacteria. In addition, ...

New complexes of nickel (II) have been synthesized in the reaction mixture of nickel (II) acetate and 4-hydroxy-2-oxo-2Hchromene-3-carboxamide. Bis(4-hydroxy-2-oxo-2H-chromene-3carboxamidato-O,O)nickel (II) and diaquabis(4-hydroxy-2-oxo-2Hchromene-3-carboxamidato-O,O)nickel (II) were characterized by elemental analysis, IR spectroscopy and ESI mass spectrometry. Elemental analysis and mass spec...
