A total of 42 benzyl- and pyridylmethyl amines were synthesized either by reductive amination of aromatic/heteroaromatic aldehydes with amines or by conjugate addition of amines to the cinnamates followed by reduction of the ester group with lithium aluminium hydride to the respective propanolamines. All the synthesized compounds were evaluated against both avirulent and virulent strains of Mycobacterium
Novel dinuclear manganese(III) complexes with bi- or tridentate and bridging tetradentate Schiff base ligands: preparation, properties and catalase-like function
However, the results suggested that the two manganese(III) ions in these complexes are bridged by one sal-m-xylylene or salpentn ligand to form a dinuclearcomplex, and each complex has an arrangement similar to that of the mononuclear complex 2. The reactivities of these manganese(III) complexes toward H2O2 have been found that the dinuclearcomplexes 4a–e, 5a, and 5b can decompose excess amounts

possess metal-chelating properties and have been used as ligands in organic synthesis and as scaffolds for developing therapeutic agents. Fourteen such compounds were synthesized in order to explore their ability to inhibit the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). Human (h) isoforms hCA I, hCA II, hCA IX and hCA XII were included in the investigation. Several aliphatic and aromatic spacers
