A series of Fe(II) complexes [(L)₂Fe] and Fe(III) complexes [(L)₂Fe]Cl from Fe(II)/(III) chlorides and N-(8-quinolyl)-X-salicylaldimine Schiff base ligands (HL, Hqsal-X₂/X: X = 3,5-Br₂, 3,5-Cl₂, 5-Br, 5-Cl) were successfully synthesized and characterized by spectroscopic (FT-IR, ¹H-NMR), mass spectrometry, thermogravimetric anal. (TGA), and single crystal X-ray crystallog. techniques. The interaction of complexes 1-8 with calf thymus DNA (CT-DNA) was determined by UV-Vis and fluorescence spectroscopy. The complexes exhibited good DNA-binding activity via intercalation. The mol. docking between a selected complex and DNA was also investigated. The in vitro anticancer activity of the Schiff base ligands and their complexes were screened against the A549 human lung adenocarcinoma cell line. The complexes showed anticancer activity toward A549 cancer cells while the free ligands and iron chloride salts showed no inhibitory effects at 100μM. In this series, complex [Fe(qsal-Cl₂)₂]Cl (6) showed the highest anticancer activity against A549 cells (IC₅₀ = 10μM). This is better than two well-known anticancer agents (Etoposide and Cisplatin). Furthermore, the possible mechanism for complexes 1–8 penetrating A549 cells through intracellular ROS generation was investigated. The complexes containing dihalogen substituents 1, 2, 5, and 6 can increase ROS in A549 cells, leading to DNA or macromol. damage and cell-death induction.

Willinger, Max;Reimhult, Erik research published 《 Thermoresponsive Nanoparticles with Cyclic-Polymer-Grafted Shells Are More Stable than with Linear-Polymer-Grafted Shells: Effect of Polymer Topology, Molecular Weight, and Core Size》, the research content is summarized as follows. Polymer brush-grafted superparamagnetic iron oxide nanoparticles can change their aggregation state in response to temperature and are potential smart materials for many applications. Recently, the shell morphol. imposed by grafting to a nanoparticle core was shown to strongly influence the thermoresponsiveness through a coupling of intrashell solubility transitions and nanoparticle aggregation. We investigate how a change from linear to cyclic polymer topol. affects the thermoresponsiveness of poly(2-isopropyl-2-oxazoline) brush-grafted superparamagnetic iron oxide nanoparticles. Linear and cyclic polymers with three different mol. weights (7, 18, and 24.5 kg mol^-1) on two different core sizes (3.7 and 9.2 nm) and as free polymer were investigated. We observed the critical flocculation temperature (CFT) during temperature cycling dynamic light scattering experiments, the critical solution temperature (CST), and the transition enthalpy per monomer during differential scanning calorimetry measurements. When all conditions are identical, cyclic polymers increase the colloidal stability and the critical flocculation temperature compared to their linear counterparts. Furthermore, the cyclic polymer shows only one uniform transition, while we observe multiple transitions for the linear polymer shells. We link the single transition and higher colloidal stability to the absence in cyclic PiPrOx shells of a dilute outer part where the particle shells can interdigitate.

The chalcogen bonding (ChB) ability of Te is studied in sym. diaryl ditellurides ArTeTeAr, Ar = Ph, 3,4-(OMe)₂C₆H₃, 3,5-(CF₃)2C₆H₃, 2-CF₃C₆H₄, 3,5-(Cl)₂C₆H₃, 3,5-(t-Bu)₂C₆H₃. Among the two Te σ-holes, the one along the less polarized Te-Te bond was calculated as the more electropos. This counter-intuitive situation is due to the hyperconjugation contribution from Te lone pair to the σ* of the adjacent Te which coincides with σ-hole along the more polarized Te-Ar bond. Diaryl ditellurides showed notable structural features in the solid state as a result of intermol. Te···Te ChB, such as a Te₄ rectangle through dimer aggregation or a triangular Te₃ motif, where one Te interacts with both Te atoms of a neighboring mol. through both its σ-hole and lone pair, in a slightly frustrated geometry. Lewis acidity of diaryl ditellurides was also evaluated by NMR with R₃PO as σ-hole acceptors in different solvents. Thus, ¹²⁵Te NMR allowed monitoring Te···O interaction and delivering association constants (K_a) for 1 : 1 adducts. The highest value of K_a=90 M^-1 was measured for the adduct between diaryl ditellurides bearing CF₃ groups and Et₃PO in cyclohexane. Notably, by using nBu₃PO, Te···O interaction was revealed by ¹⁹F-¹H HOESY showing spatial proximity between CF₃ and CH₃ of nBu₃PO.
