An Organometallic Umpolung Approach for Iron-Mediated Propargylic C-H Etherification.

Propargylic ethers serve as useful intermediates for the synthesis of a variety of complex targets. However, propargylic substitution of prefunctionalized alkyne starting materials remains the dominant method for the synthesis of propargyl ethers, while direct etherification of simple alkynes via propargylic C-H functionalization remains largely underreported. Herein, we report an organometallic umpolung approach for iron-mediated C-H propargylic etherification.

In utero and childhood exposure to the great Chinese famine and risk of aging in adulthood.

Background Early-life exposure to famine may influence the occurrence of chronic diseases and aging in midlife among those exposed. This study aims to explore the relationship between exposure to the Chinese Great Famine and aging in middle-aged individuals. Methods Participants born in 1963-1965 (unexposed), 1959-1961 (in utero exposure), and 1955-1957 (childhood exposure) from the Kailuan Study were included.

Cycle-ESM: Generation-assisted classification of antifungal peptides using ESM protein language model.

The rising prevalence of invasive fungal infections and the emergence of antifungal resistance highlight the urgent need for new antifungal medications. Antifungal peptides have emerged as promising alternatives to traditional antimicrobial agents. The identification of natural or synthetic antifungal peptides is crucial for advancing antifungal drug development.

Cardiovascular toxicity of anaplastic lymphoma kinase inhibitors for patients with non-small cell lung cancer: a network meta-analysis.

We conducted network meta-analysis to assess cardiovascular toxicity of anaplastic lymphoma kinase-tyrosine kinase inhibitors (-TKIs). Eleven articles involving 2855 patients and six interventions including crizotinib, alectinib, ceritinib, lorlatinib, brigatinib and chemotherapy were analyzed. No significant difference was observed in overall cardiovascular risk among -TKIs.

Lack variation of low slow-wave activity over time in the frontal region in NREM sleep may be associated with dyskinesia in Parkinson's disease.

Objective: Levodopa-induced dyskinesia (DYS) adversely affects the quality of life of Parkinson's disease (PD) patients. However, few studies have focused on the relationship between DYS and sleep and electroencephalography (EEG). Our study aimed to establish the objective physiological indicators assessed by polysomnography (PSG) that are associated with DYS in PD patients.

Contagion of depression: a double-edged sword.

Depression is a significant mental health issue with extensive economic implications, and recent studies suggest it may be transmitted between individuals. However, the mechanisms of this contagion remain unclear, and the social buffering effect has been understudied. This research employs three rodent models, including stress crossover, cohabitation-induced, and non-contact induced depression contagion models, to explore these mechanisms.

Copper ions: The invisible killer of cardiovascular disease (Review).

Copper, a vital trace element, is indispensable for the maintenance of physiological functioning, particularly in the cardiac system. Unlike other forms of cell death such as iron death and apoptosis, copper‑induced cell death has gained increasing recognition as a significant process influencing the development of cardiovascular diseases. The present review highlights the significance of maintaining copper homeostasis in addressing cardiovascular diseases.

A switch strategy for the synthesis of C4-ethylamine indole and C7-aminoindoline controllable carbon elimination.

Controllable β-carbon elimination to extrude norbornene remains a long-standing challenge in palladium and norbornene chemistry. Herein, this manuscript describes a switchable synthesis of biologically active C4-ethylaminoindole and C7-aminoindoline scaffolds by controlling β-carbon elimination, utilizing aziridine as a C-H ethylamination reagent through a C-N bond cleavage reaction. Furthermore, the protecting groups of the product can be easily removed, offering an unusual method for the synthesis of dopamine receptor agonists.

Tailoring parameters for QM/MM simulations: accurate modeling of adsorption and catalysis in zirconium-based metal-organic frameworks.

Quantum mechanics/molecular mechanics (QM/MM) simulations offer an efficient way to model reactions occurring in complex environments. This study introduces a specialized set of charge and Lennard-Jones parameters tailored for electrostatically embedded QM/MM calculations, aiming to accurately model both adsorption processes and catalytic reactions in zirconium-based metal-organic frameworks (Zr-MOFs). To validate our approach, we compare adsorption energies derived from QM/MM simulations against experimental results and Monte Carlo simulation outcomes.

A C-H functionalization approach to diverse nitrogenous scaffolds through conjugate addition of catalytic allyliron nucleophiles.

Cyclopentadienyliron(ii) dicarbonyl complexes capable of coordinating to and enhancing the acidity of a range of unsaturated substrates have emerged as a new class of base-metal derived catalysts for C-H functionalization. In this manuscript, the iron-catalyzed C-H functionalization of allylic C(sp)-H bonds using nitrogen containing α,β-unsaturated carbonyl compounds as coupling partners is reported. Employing a cationic cyclopentadienyliron dicarbonyl complex, this redox neutral process converts simple alkenes into allylic anion equivalents for 1,4-addition into maleimides, acyclic α,β-unsaturated imides, and vinylogous amides.

Direct Synthesis of C4-Acyl Indoles via C-H Acylation.

The direct synthesis of C4-acyl indoles deprived of C2 and C3 substituents has proven to be challenging, with scarce efficient synthetic routes being reported. Herein, we disclose a highly site-selective palladium-catalyzed C-H acylation for the construction of C4-acyl indoles via a Catellani-Lautens cyclization strategy. In addition, we systematically studied the C-H acylation mechanism of iodoaniline through density functional theory (DFT) calculations and combined experimental results to elucidate the principle of high chemoselectivity brought by triazine benzoate as an acylation reagent.
