A convenient synthesis of 2'-deoxy-2-fluoroadenosine from commercially available 2-fluoroadenine is described. The coupling reaction of silylated 2-fluoroadenine with phenyl 3,5-bis[O-(t-butyldimethylsilyl)]-2-deoxy-1-thio-D-erythro-pentofuranoside gave the corresponding 2-fluoro-2'-deoxyadenosine derivative (alpha/beta = 1:1) in good yield. The alpha- and beta-anomers were separated by chromatography, and then desilylated to give compounds 1a and 1b.

Efficient room-temperature sensors for toxic gases are essential to ensure a safe and healthy life. Conducting frameworks have shown great promise in advancing gas sensing technologies. In this study, two new organic-inorganic frameworks [CuX(PPh)(L)], CP1 (X = I) and CP2 (X = Br) have been synthesized using (pyridin-4-yl)-N-(4H-1,2,4-triazol-4-yl)methanimine (L) and triphenylphosphine.

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous group of immature myeloid cells playing a critical role in immune suppression. In vitro-generated MDSCs are a convenient tool to study the properties of tumour-associated MDSCs. Here, we compared six protocols for in vitro generation of functional mouse MDSCs from bone marrow progenitors.

A photoinduced copper-mediated acyloxylation of arylthianthrenium or arylphenoxathiinium salts with either aliphatic or aromatic carboxylic acids is described for the convenient synthesis of -aryl esters. The reaction has shown obvious advantages, such as high efficiency, good functional group tolerance, excellent chemoselectivity, and capacity for esterification of complex drug molecules, offering a practical synthetic route to multifunctionalized and sterically congested -aryl esters, which are potentially useful in the development of new prodrugs or twin drugs.

Skeletal muscles account for ~30-40% of the total weight of human body and are responsible for its most important functions, including movement, respiration, thermogenesis, and glucose and protein metabolism. Skeletal muscle damage negatively impacts the whole-body functioning, leading to deterioration of the quality of life and, in severe cases, death. Therefore, timely diagnosis and therapy for skeletal muscle dysfunction are important goals of modern medicine.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.
