  Binding interaction, conformational change, and molecular docking study of N-(pyridin-2-ylmethylene)aniline derivatives and carbazole Ru(II) complexes with human serum albumins

  摘要：

  New [RuCl2(1,5cod)(L1)] (1), [RuCl2(1,5cod)(L2)] (2), [RuCl2(1,5cod)(L3)1 (3), [RuCl2(1,5cod)(L4)] (4), [RuCl2(1,5cod)(L5)] (5) (L = (p-R-N-(pyridin-2-ylmethylene)aniline), R = H (L1), Cl (12), OCH3 (L3), CH3 (L4), L5 = (9-ethyl-N-(pyridin-2-ylmethylene)9H-carbazole-3-amine and 1,5cod = eta(4)-cyclooctadiene) complexes were synthesized and characterized by H-1 and C-13 NMR, melting point analysis, elemental analysis, HR-Mass spectrometry, FT-IR and UV-Vis spectroscopy. The single crystal X-ray structures of complexes 1, 2 and 3 revealed coordination of the ligands to the Ru(II) center in a bidentate manner via the N atoms. The geometry around the Ru(II) center is pseudooctahedral with the two Cl atoms and the pi-bonds of the cydooctadiene occupying the coordination sites. Interactions of Ru(II) complexes 1-5 with human serum albumins (HSA) were investigated using UV-Vis, synchronous emission and circular dichroism spectroscopy. The results demonstrated that the Ru(II) complexes 1-5 have significantly strong interaction with HSA proteins. Complexes 1, 3 and 5 showed moderate-to-high binding constants (K-b) 1.77 x 10(5) dm(3) mol(-1) (1), 1.07 x 10(5) dm(3) mol(-1) (3) and 1.07 x 10(5) dm(3) mol(-1) (5) respectively. Circular dichroism (CD) studies revealed decreased alpha-helix content within HSA upon interaction with complexes 1-5, suggesting a conformational change of the HSA secondary structure. Also, molecular docking studies were carried out to identify the binding models of the HSA-Ru complexes and binding energy of complexes 1-5 in HSA, which further revealed the contribution of amino acid residues of HSA in Ru(II) complex binding.

Density functional theory (DFT) was used to calculate the relevant molecular orbital energy levels, binding energies, bond angles and bond lengths of the synthesised Ru(II) complexes. The DFT study of the complexes 1–3 further supported the biological activity of the complexes and showed good
