Kordestani, Nazanin;Rudbari, Hadi Amiri;Fateminia, Zohreh;Caljon, Guy;Maes, Louis;Mineo, Placido G.;Cordaro, Annalaura;Mazzaglia, Antonino;Scala, Angela;Micale, Nicola research published 《 Antimicrobial and antiprotozoal activities of silver coordination polymers derived from the asymmetric halogenated Schiff base ligands》, the research content is summarized as follows. A series of polymeric silver(I) complexes with Schiff base ligands containing pyridine and 3,5-halogen substituted phenol moieties were synthesized and characterized by spectroscopic methods and in the case of Ag6 also by X-ray crystallog. All silver(I) complexes (Ag1-Ag8) were evaluated for their biol. activity against a panel of pathogens including the protozoa Trypanosoma cruzi, T. brucei, T. rhodesiense and Leishmania infantum; the bacteria Staphylococcus aureus, Escherichia coli, Mycobacterium tuberculosis H37Ra and the yeast Candida albicans. Cytotoxicity evaluation was carried out on human lung fibroblasts (MRC-5) and on primary peritoneal mouse macrophages. The most relevant result reveals antileishmanial activity potential with all complexes demonstrating higher potency than the reference drug miltefosine. Complexes with the best antiprotozoal profile (i.e., Ag2 and Ag7) were selected for incorporation into poly(lactic acid) nanoparticles (PLA NPs) with the aim to enhance selectivity. PLA/Ag2 NPs and PLA/Ag7 NPs exhibited adequate physicochem. properties, i.e., average size of 263 ± 60 nm and 225 ± 6 nm, resp., good entrapment efficiency (69% and 63%), loading content (6.2% and 5.7%) and stability. The cytotoxicity of PLA/Ag2 NPs and PLA/Ag7 NPs on MRC-5 cells was reduced with respect to the “free” metal complexes by ∼2-fold and ∼6-fold, resp.
Product Details of C7H4Br2O2, 3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes.
3,5-Dibromosalicylaldehyde, also known as 3,5-Dibromosalicylaldehyde, is a useful research compound. Its molecular formula is C7H4Br2O2 and its molecular weight is 279.91 g/mol. The purity is usually 95%.
3,5-Dibromosalicylaldehyde reacts with alkyl cyanoacetates in the presence of ammonium acetate to yield 4H- chromenes. 3,5-Dibromosalicylaldehyde can be used in the synthesis of Schiff base and can be used as reactant for synthesis of Schiff base ligands which forms mononuclear complexes with copper(II), nickel(II), zinc(II) and cobalt(II).
3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
