Synthesis, structure, DNA and protein binding studies, and cytotoxic activity of nickel(II) complexes containing 3,3-dialkyl/aryl-1-(2,4-dichlorobenzoyl)thiourea ligands
摘要:
A new series of nickel(II) complexes of the type [Ni(L)(2)] (1-6) has been synthesized by using the 3,3-dialkyliaryl-1-(2,4-dichlorobenzoyl)thiourea ligands, and characterized by analytical and spectral (NMR, FT-IR and UV-Vis) techniques. The structures of the ligands (HL1, HL2 and HL3) and complexes (2 and 5) have been confirmed by single crystal X-ray diffraction studies. The interaction of the nickel(II) complexes (2-5) with calf thymus (CT) DNA and bovine serum albumin (BSA) protein was investigated using UV-Vis and fluorescence spectroscopic methods. Absorption and emission spectral studies indicate that complex 2 interacts with CT DNA and BSA protein more strongly than the other complexes (3, 4 and 5). Complexes 2 and 5 exhibited good cytotoxicity against A549 and HT29 cell lines at 50 mu M concentration. (C) 2014 Elsevier Ltd. All rights reserved.

4-dichlorobenzoyl)thiourea (HL3) in benzene gave new four-coordinated tetrahedral copper(I) complexes of the type [CuCl(HL)(PPh3)2] (1–3) [HL = 3,3-dialkyl/aryl-1-(2,4-dichlorobenzoyl)thiourea derivatives]. These complexes were then characterized by analytical and spectroscopic (IR, UV/Vis, 1H, 13C and 31P NMR) techniques. The molecular structure of a representative complex, [CuCl(HL1)(PPh3)2] (1), was determined
