Synthesis, characterization, antimicrobial and cytotoxic activity of novel half-sandwich Ru(II) arene complexes with benzoylthiourea derivatives. J Inorg Biochem. 2020 Jun 26;210:111164 Authors: Obradović D, Nikolić S, Milenković I, Milenković M, Jovanović P, Savić V, Roller A, Đorđić Crnogorac M, Stanojković T, Grgurić-Šipka S Abstract Three new ruthenium(II)-arene complexes, [Ru(η6-p-cymene)(L1)Cl2] (C1) where L1 is N-((4 methoxyphenyl)carbamothioyl)benzamide; [Ru(η6-p-cymene)(L2)Cl2] (C2) where L2 is 4-(3-benzoylthioureido)benzoic acid and [Ru(η6-p-cymene)(L3)Cl2] (C3) where L3 is methyl 4-(3- benzoylthioureido)benzoate have been synthetized, characterized and evaluated for their antimicrobial and anticancer activity. Characterization was performed using 1H and 13C NMR, IR spectroscopy, mass spectrometry, electrical conductivity measurements and X-Ray diffraction analysis. X-Ray diffraction analysis of C1 showed typical expected "piano-stool" geometry with ruthenium coordinated to ligand via nitrogen and sulfur atoms of benzoylthiourea derivatives. Interesting, in herein described complex, upon coordination the four-membered ring was formed, instead of six-membered chelate common for this type of ligands. Cytotoxic activity was determined in human cervix adenocarcinoma (HeLa) cell line and IC50 values ranged from 29.68 to 52.36 μM and the complexes were more active than related ligands (except in case of C2 where...
