Copper(II), a Peculiar Metal Ion for Complexation with Monensin A Ionophore

Chemistry – A European Journal, EarlyView.
Copper(II) forms three chiral and EPR‐active complexes with monensinate A in methanol. Beside the bis [CuL2] and mono [CuL]+ species, the new dinuclear construct [Cu2L]3+ exhibits an [ML]+‐type and a metal salt‐type copper(II) centers weakly bound to each other through counter ion(s) and thus, being magnetically independent.

Incorporation of cytochrome oxidase into cardiolipin bilayers and induction of nonlamellar phases. [PDF]

, 1990
Cytochrome oxidase from beef heart has been lipid-substituted with beef heart cardiolipin. The lipid phase behavior and protein aggregation state of the reconstituted complexes have been studied with 31P NMR, freeze-fracture electron microscopy, and ...

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication

Chemistry – A European Journal, EarlyView.
This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

Increased SK3 expression in DM1 lens cells leads to impaired growth through a greater calcium-induced fragility [PDF]

, 2006
Although cataract is a characteristic feature of myotonic dystrophy type 1 (DM1), little is known of the underlying mechanisms. We generated four lens epithelial cell lines derived from DM1 cataracts and two from age-matched, non-DM cataracts. Small-pool

Evaluation of the Therapeutic Potential of Bioactive Materials Based on a Complex of Oxidovanadium(IV) and Exopolysaccharide Levan in a Model of Insulin Resistance in Mice

ChemMedChem, EarlyView.
A low‐toxicity bioactive composition of oxidovanadium(IV) and exopolysaccharide levan is synthesized, characterized, and shown to reduce hyperglycemia, hypertriglyceridemia, and TyG index in a mice model of dexamethasone‐induced insulin resistance. Bioactive compositions containing vanadium complexes have been a viable strategy for constructing more ...

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, EarlyView.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

Near‐Infrared Triggered Anion Transport Induces Cancer Cell Death

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Photo‐responsive transmembrane anion transporters that are activated with NIR light are reported. Experiments in cancer cells revealed that NIR activation of the ionophore triggered near‐IR light‐dependent chloride influx and triggered cell death. Abstract Artificial transmembrane anion carriers have shown potential in biological research and medicine,
