A new mixed nickel–sodium complex has been synthesized from Ni(ClO4)2 and tris(8‐methyl 2‐oxo‐quinolidine amino ethylamine) with a 1:1 molar ratio in methanol and has been characterized by various analytical, spectroscopy and X‐ray diffraction studies which confirmed an octahedral geometry around the nickel ion. Further, structural optimization of the complex was performed using DFT calculations. The ligand and complex were evaluated for their binding affinity with CT‐DNA and an intercalative type of binding interaction was proposed from the absorption and fluorescence titration experiments. Albumin binding interaction of the ligand and complex was determined by absorption, fluorescence and synchronous spectral techniques at room temperature, suggesting the static quenching mechanism of BSA with the compounds. Antioxidant studies revealed the radical scavenging potential of Ni(II) complex. The anticancer activity of the ligand and complex was probed via in vitro cytotoxicity against human breast (MCF7) and lung (A549) cancer cell lines by MTT assay. Further, cytological changes observed in acridine orange/ethidium bromide and DAPI staining methods validated the cytotoxic potential of the complex.
A series of novel 2-(diaryl methanone)-N-(4-oxo-2-phenyl-thiazolidin-3-yl)-acetamides were synthesized by various Schiff bases of (4-benzoyl-phenoxy)-aceto hydrazide with thioglycolic acid. The structures of the newly synthesized compounds were confirmed by IR, (1) H NMR, mass spectra, and C, H, N analysis. Further, all the synthesized compounds 9a-n were evaluated for xanthine oxidase (XO) inhibition and antioxidant properties. Among all the tested compounds, 9f, 9m, and 9n demonstrated potent XO inhibition of 52, 76, and 26%, respectively, compared to the standard drug allopurinol, which is evident from in vitro and in silico analysis. On the other hand, compounds 9c, 9d, and 9k exhibit potent antioxidant properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
