The title linear trinuclear copper(II) complex, [Cu(3)(C(17)H(20)N(2)O(2))(2)Cl(2)], was obtained from N,N'-bis-(2-hydroxy-benz-yl)-1,3-propane-diamine and CuCl(2). The overall charge of the three Cu(2+) ions is balanced by four deprotonated phenol groups and two Cl(-) ligands. The complex is centrosymmetric with the central Cu(2+) occupying a special position (). This Cu(2+) ion is coordinated by the four phenolate O atoms in a square-planar fashion. The second Cu(2+) occupies a general position in a square-pyramidal fashion. Two phenolate O atoms and two amine N form the basal plane, with Cl(-) ligands occupying the fifth coordination site.

In this study, we synthesized 12 monofunctional tridentate ONS-donor salicylaldimine ligand ()-based Ru(II) complexes with general formula [(Ru()(-cymene)]·Cl (-), characterized by H NMR, C NMR, UV, FT-IR spectroscopy, HR-ESI mass spectrometry, and single-crystal X-ray analysis showing ligand's orientation around the Ru(II) center. All 12 of these 12 complexes were tested for their anticancer activities in multiple cancer cells. The superior antitumor efficacy of , , and was demonstrated by reduced mitochondrial membrane potential, impaired proliferative capacity, and disrupted redox homeostasis, along with enhanced apoptosis through caspase-3 activation and downregulation of Bcl-2 expression.

Objectives: Immune checkpoint inhibitor (ICI)-containing treatment is currently prescribed as first-line treatment for all patients with advanced non-small cell lung cancer (NSCLC) without targetable driver mutations. However, only 30-45% of patients show no progression within 12 months after treatment start. Various biomarkers are being studied to save costly and potentially harmful treatment in non-responders.

Objective: This study aims to accurately classify ATN profiles using highly specific amyloid and tau PET ligands and MRI in patients with cognitive impairment and suspected Alzheimer's disease (AD). It also aims to explore the relationship between quantified amyloid and tau deposition and cognitive function.
Methods: Twenty-seven patients (15 women and 12 men; age range: 64-81 years) were included in this study.

A series of 2,6-di(pyrazine-2-yl)pyridine (dppy) ligands - of varying substituents of different electronic nature (-NMe, -OMe,-Me, and -Cl) in the 4-position of the pyridine moiety has been designed and synthesized to study the binding behavior of the dppy ligands towards Bovine Serum Albumin (BSA), a low-cost serum albumin protein. The interaction between ligands and BSA has been studied using UV-Visible and fluorescence spectroscopy and molecular docking studies. The fluorescence of BSA was found to be quenched in the presence of all the ligands , in which ligand , having the most electron donating group NMe exhibits the maximum binding affinity towards BSA.

Nowadays, benzimidazole and its derivatives are widely assembled into multifunctional materials with various properties such as mechanochromism, photochromism, thermochromism and electrochromism. Herein, two novel zinc(II) coordination compounds, [Zn(L)Br]·2HO (1) and [Zn(L)Cl]·2HO (2) (L = tetra(1-benzo[]imidazol-2-yl)ethene), have been constructed one-pot facile synthesis from bis(1-benzo[]imidazol-2-yl)methane (L) and zinc(II) salts. The ligand L with a CC double bond was formed by C-C coupling of two sp-C atoms of L in solvothermal synthesis, which provides a new strategy to generate the conjugation system conveniently.
