New Ce(III) Complex Compounds of 2-(N,N- dimethylbiguanidil)-penta-1,5-dioic Acid with Biological Activity

摘要

The paper present the biological properties, total antioxidant capacity and antimicrobial activity against different Gram positive and Gram negative strains and fungi, of some new Ce(III) complex compounds with Schiff base as ligands; the ligands were obtained by condensation between a-ketoglutaric acid and N,N-dimethylbiguanide (base and hydrochloride), in well-established condition. The new synthesized ligands were obtained as hydrochloride salt (2-(N,N-dimethylbiguanidyl)-penta-1,5-dioic hydrochloride acid, V) and also in neutral form (2-(N,N-dimethylbiguanidyt)-penta 1,5-dioic acid, V); the new ligands and theirs Ce(III) complex compounds have been physico-chemically characterized by elemental chemical analysis, molar electrical conductivity, FT/IR, UV-Vis spectrometry and NMR.
