A dinuclear bis(μ-acetate) dicopper(II) complex [Cu₂L₂(μ_1.1-CH₃COO^–)₂] was synthesized from a tridentate NNO Schiff Base ligand L (L = 2,4-dibromo-6-((3-(methylamino)propylimino)methyl)phenol) and characterized by elemental, UV-visible, FTIR, ¹H NMR, and electrospray ionization-mass spectrometry (ESI-MS) spectroscopic studies. The single-crystal x-ray structure, different noncovalent interactions, Hirshfeld surface anal., and d. functional theory (DFT) studies of the dinuclear complex were determined by crystallog. computational studies. The structural study exposed that the complex consists of the pentacoordinated double μ_1.1-acetato-bridged dinuclear units of Cu(II), and it is a centrosym. dimer in which the center of inversion lies at the midpoint of two Cu(II) ions. Hirshfeld surface and DFT studies pointed out the probable potentiality of the crystal in prospective binding with the protein. This was exptl. verified by carrying out the binding interaction studies against bovine serum albumin (BSA) protein using various spectroscopic methods. The copper(II) complex could strongly bind to BSA and could quench the intrinsic fluorescence of BSA. Further, the studied complex was appraised for cell viability studies against SiHa cancer cells. Cell viability increases with time, demonstrating the biocompatible nature of the complex.

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.
