cis-bis(N-benzoyl-N0 ,N0 -dibenzylthioureido) platinum(II) : synthesis, molecul...

In this paper, the title compound was synthesized from N-benzoyl-N′,N′-dibenzylthiourea ligand and potassium tetrachloroplatinate(II), and its interaction with human (HSA) and bovine (BSA) serum albumin was evaluated. Also, the crystal structure was determined from single-crystal X‐ray diffraction, confirming that the platinum atom is coordinated with two chelated N-benzoyl-N′,N′-dibenzylthiourea ligands in a d...

Understanding the conformational changes and molecular structure of furoyl thio...

1-Acyl thioureas [R1C(O)NHC(S)NR2R3] are shown to display conformational flexibility depending on the degree of substitution at the nitrogen atom. The conformational landscape and structural features for two closely related thioureas having R1=2-furoyl have been studied. The un-substituted 2-furoyl thiourea (I) and its dimethyl analogue, i.e. 1-(2-furoyl)-3,3-dimethyl thiourea (II), have been synthesized and fu...

Ruthenium(II) complexes of 1,3-thiazolidine-2-thione : cytotoxicity against tum...

Three newmixed and mononuclear Ru(II) complexes containing 1,3-thiazolidine-2-thione (tzdtH) were synthesized and characterized by spectroscopic analysis, molar conductivity, cyclic voltammetry, high-resolution electrospray ionization mass spectra and X-ray diffraction. The complexes presented unique stereochemistry and the proposed formulae are: [Ru(tzdt)(bipy)(dppb)]PF6 (1), cis-[Ru(tzdt)2(PPh3)2] (2) and tra...

Ru(II)-based complexes with N-(acyl)-N′,N′-(disubstituted)thiourea ligands : sy...

Four ruthenium(II)-based complexeswith N-(acyl)-N′,N′-(disubstituted)thiourea derivatives (Th)were obtained. The compounds, with the general formula trans-[Ru(PPh3)2(Th)(bipy)]PF6, interact with bovine serum albumin (BSA) and DNA. BSA-binding constants, which were in the range of 3.3–6.5 × 104 M−1, and the thermodynamic parameters (ΔG, ΔH and ΔS), suggest spontaneous interactions with this protein by electrosta...
