Seven enantiomeric pairs of palladium complexes, [Pd(pic)(R or S)-N-1-(phenyl)ethyl-2,4-X1,X2-salicylaldiminate]NO3, [Pd(pic)(R or S)]NO3 (X1 = X2 = Cl, Br, I, H; X1/X2 = Br/Cl), were synthesized by the reaction of enantiopure halogen-substituted Schiff bases (R or S)-N-1-(phenyl)ethyl-2,4-X1,X2-salicylaldimine with [Pd(pic)Cl2] (pic = 2-picolylamine). The composition and structure of the complexes were confirmed by FT-IR, 1H NMR and 13C NMR spectroscopy, elemental anal. and x-ray crystallog. The electronic structure of the reported complexes was investigated using UV-vis absorption and electronic CD (ECD) spectroscopy, complemented by DFT/TDDFT modeling. To investigate the effect of chirality and different halogen substituents on the anticancer activity of the complexes, the cytotoxic activity of all fourteen complexes was tested in the human breast cancer cell lines MDA-MB-231 and MCF-7 at 24 h using the colorimetric MTT assay. Also, the cell death mechanism was assessed using the annexin V/propidium iodide (AV/PI) cytometry-based assay.
90-59-5, 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., Computed Properties of 90-59-5
