Summary: Phosphines have been crucial in the development of transition metal-catalysed processes, overcoming synthesis challenges through fine-tuning electronic and steric properties. Caged phosphines, with excellent control over steric and electronic properties, are widely used as ligands in catalytic reactions.

Summary: This study investigated the behavior and neurobiological effects of intermittent nicotine intake in rats. The results suggest that intermittent nicotine intake may lead to increased craving and enhanced response to nicotine-associated cues. Additionally, intermittent nicotine intake also caused increased nicotine binding in the brain and specific changes in the proteome of certain neural structures.

Summary: Femtosecond transient absorption, nanosecond transient absorption, and nanosecond resonance Raman spectroscopy techniques combined with density functional theory calculations were used to investigate the photocyclization and photorelease mechanisms of a diarylethene compound. This study provides a deeper understanding of these reactions and can aid in the future design of functionalized diarylethene derivatives for specific applications.

Summary: Despite solid data supporting the involvement of nicotinic receptors in neurological and neuropsychiatric diseases, their potential as a therapeutic target has not been fully realized due to complex factors such as the widespread action of the cholinergic system and the biophysical mechanism of nicotinic receptors. Conventional drug development strategies focus on receptor subtype-specific action, while exploring the broad agonist nicotine in the clinic. Prototoxins, a little-explored avenue, show promise as nicotinic receptor drugs and have potential advantages over targeting specific receptor subtypes. Their allosteric effects and binding specificity provide possibilities for more effective and nuanced therapeutic approaches.

Summary: The durability of RuO2 as an acidic oxygen evolution reaction catalyst can be significantly improved by pretrapping RuCl3 precursors within a cage compound possessing 72 aromatic rings, leading to well carbon-coated RuOx particles (Si-RuOx@C) after calcination. The catalyst exhibits excellent catalytic activity and stability during OER, while RuOx prepared from similar non-tied compounds does not show such performance.

Summary: The study developed an in situ electrochemical method to determine the release of caged compounds by using fast-scan cyclic voltammetry at carbon-fiber microelectrodes. A linear calibration curve for the released glutamate was established using a model system and high-performance liquid chromatography. This approach allowed for the correction of light artifacts and residual caged molecules in solution, demonstrating successful validation in intact zebrafish brain tissue.

Summary: Evidence has shown a strong relationship between smoking and epithelial mesenchymal transition (EMT) in lung adenocarcinoma (LUAD). This study identifies a novel pathway involving alpha 5-nicotinic acetylcholine receptor (alpha 5-nAChR), PLEK2, and CFL1 in nicotine-induced LUAD progression. The alpha 5-nAChR/PLEK2/CFL1 pathway contributes to cell migration, invasion, and stemness in LUAD.

Summary: Smoking is the dominant risk factor for small cell lung cancer (SCLC) and is associated with worse clinical outcomes and reduced efficacy of chemotherapy. Nicotine and its metabolite, cotinine, have been found to decrease the efficacy of platinum-based chemotherapies and accelerate chemoresistance in SCLC cells. These findings highlight the importance of tobacco cessation and control of nicotine replacement therapy in SCLC management.

Summary: This study investigated the mechanism of how nicotine-induced dopamine (DA) plasticity protects substantia nigra (SN) neurons against nigrostriatal damage in Parkinson's disease (PD). The results showed that chronic nicotine treatment led to upregulation of transcription factor Nurr1 and DA-synthesizing enzyme tyrosine hydroxylase (TH) in GABAergic neurons in the SN. Nicotine also reduced the number of alpha-synuclein-expressing neurons and rescued motor deficits in PD mice. Importantly, the activation of GABA neurons and Nurr1 overexpression were sufficient to mimic nicotine-mediated dopamine plasticity. This study provides insights into developing new strategies for neurotransmitter replacement in PD.

Summary: The endocytosis of alpha 4 beta 2 nicotinic ACh receptors occurs through clathrin-mediated endocytosis in a dynamin-dependent manner. Src-mediated phosphorylation of the nAChR alpha 4 subunit at Y575 by 14-3-3 eta is required for endocytosis, with assistance from beta-arrestin1 and GRK2. Endocytosis leads to ubiquitination and down-regulation of alpha 4 beta 2 nAChRs.

Summary: An unusual 1,2-ferrocenyl migration was observed after reactions of [Ru(dppe)Cp][BAr4F] with diferrocenylacetylene, expanding the scope of group rearrangments beyond methyl and phenyl entities. Bimetallic bis(vinylidene) complexes were formed from ferrocene-containing bis(alkynes) following two consecutive rearrangements.

Summary: This paper investigates the geometries, energy landscapes, and magnetic parameters of copper(II) amino acid compounds using density functional theory calculations. The results show that certain conformers with histaminate-like and glycine-like modes have low Gibbs free energies and high metal-binding affinities. The predicted conformations reproduce the experimental electron paramagnetic resonance parameters.

Summary: Many proteins require a metal cofactor for their function, and these metals play a role in protein folding. The study found that the metallation rates of different metal binding pathways are influenced by pH, with the less cooperative pathway being more affected by low pH conditions. Specific mixtures of structures are formed in the initial steps of metallation, and unfolding the disordered apo-MT structure hinders the formation of these preliminary structures. The compact conformation of the native apo-MT allows for rapid formation of metal-thiolate structures with high affinity, providing protection from oxidation.
