The idea of coordinating biologically active ligand systems to metal centers to exploit their synergistic effects has gained momentum. Therefore, in this report, three Ru complexes - of morpholine-derived thiosemicarbazone ligands have been prepared and characterized by spectroscopy and HRMS along with the structure of through a single-crystal X-ray diffraction study. The solution stability of - was tested using conventional techniques such as UV-vis and HRMS.

Sacubitril/valsartan (Sac/Val) belongs to the group of angiotensin receptor-neprilysin inhibitors and has been used for the treatment of heart failure (HF) for several years. The mechanisms that mediate the beneficial effects of Sac/Val are not yet fully understood. In this study we investigated whether Sac/Val influences the two proteolytic systems, the ubiquitin-proteasome system (UPS) and the autophagy-lysosomal pathway (ALP), in a mouse model of pressure overload induced by transverse aortic constriction (TAC) and in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) treated with endothelin-1 (ET1) serving as a human cellular model of hypertrophy.

Mitophagy that disrupt mitochondrial membrane potential (MMP), represents a critical focus in pharmacology. However, the discovery and evaluation of MMP-disrupting drugs are often hampered using commercially available marker molecules that target similar or identical zones. These markers can significantly interfere with, obscure, or amplify the functional effects of MMP-targeting drugs, frequently leading to clinical failures.

Chaperone-mediated autophagy (CMA) is a selective autophagic pathway responsible for degrading cytoplasmic proteins within lysosomes. Monitoring CMA flux is essential for understanding its functions and molecular mechanisms but remains technically complex and challenging. In this study, we developed a pH-resistant probe, KFERQ-Gamillus, by screening various green fluorescent proteins.

Introduction: Salmonella, a foodborne zoonotic pathogen, is a significant cause of morbidity and mortality in animals and humans globally. With the prevalence of multidrug-resistant strains, Salmonellosis has become a formidable challenge. Host-directed therapy (HDT) has recently emerged as a promising anti-infective approach for treating intracellular bacterial infections.
