Zweifel olefination for C-glycosylation.

Commun Chem

December 2024

Technische Universität Darmstadt, Clemens-Schöpf-Institut für Organische Chemie und Biochemie, Peter-Grünberg-Straße 4, 64287, Darmstadt, Germany.

C-glycosides are significant in medicinal chemistry due to their resistance to enzymatic hydrolysis, making them more stable and bioavailable compared to O-glycosides. Their unique structure also offers potential for developing drugs with improved therapeutic properties, particularly in treating diseases like diabetes and cancer. The main challenge in synthesizing C-glycosides lies in forming the carbon-carbon bond between the sugar and aglycone efficiently, while controlling the stereochemistry and minimizing side reactions.

Background: Although some evidence suggests that alcohol, substance use, and mental health issues diminish adherence to HIV Pre-Exposure Prophylaxis (PrEP) among gay, bisexual, and other men-who-have-sex-with-men (gbMSM), findings are somewhat inconsistent and have primarily derived from studies involving non-random samples. Medical chart extraction can provide unique insight by in part surmounting sampling-related limitations, as data for entire PrEP clinic populations can be examined. Our investigation entailed comprehensive chart extraction to assess the extent to which chart-reported alcohol, substance use, and mental health issues were associated with chart-reported PrEP nonadherence.

Affinity chromatography is the method of choice for the rapid purification of proteins from cell extracts or culture supernatants. Here, we present the light-responsive Azo-tag, a short peptide comprising p-(phenylazo)-L-phenylalanine (Pap), whose side chain can be switched from its trans-ground state to the metastable cis-configuration by irradiation with mild UV light. Since only trans-Pap shows strong affinity to α-cyclodextrin (α-CD), a protein exhibiting the Azo-tag selectively binds to an α-CD chromatography matrix under daylight or in the dark but elutes quickly under physiological buffer flow when illuminating the column at 355 nm.

The negative interference of treatments between the acetylcholinesterase inhibitor rivastigmine and the tau aggregation inhibitor hydromethylthionine mesylate (HMTM) has been reported in Line 1 tau-transgenic mice, which overexpress a truncated species of tau protein that is found in the core of paired helical filaments in Alzheimer´s disease (AD). However, little is known about whether such interactions could affect synapses in mice overexpressing tau carrying pathogenic mutations. Here, we have used Line 66 (L66) mice which overexpress full-length human tau carrying the P301S mutation as a model in which tau accumulates in synapses.

Plastic input and dynamics in industrial composting.

Waste Manag

December 2024

Institute for Crop Science and Resource Conservation (INRES) - Soil Science and Soil Ecology, University of Bonn, Nussallee 13, 53115 Bonn, Germany. Electronic address:

Green and biowaste, processed within large facilities into compost, is a key fertilizer for agricultural and horticultural soils. However, due to improper waste disposal of plastic, its residues often remain or even lead to the formation ofmicroplastics (1 µm - 5 mm, MiPs) in the final compost product. To better understand the processes, we first quantified 'macroplastics' (> 20 mm, MaPs) input via biowaste collection into an industrial composting plant, and, then determined MiP concentrations at five stages during the composting process (before and after shredding and screening processes), and in the water used for irrigation.

Transcranial Direct Current Stimulation (tDCS) is a non-invasive brain stimulation technique used to modulates cortical brain activity. However, its effects on brain metabolites within the dorsolateral prefrontal cortex (DLPFC), a crucial area targeted for brain stimulation in mental disorders, remain unclear. This study aimed to investigate whether prefrontal tDCS over the left and right DLPFC modulates levels of key metabolites, including gamma-aminobutyric acid (GABA), glutamate (Glu), glutamine/glutamate (Glx), N-acetylaspartate (NAA), near to the target region and to explore potential sex-specific effects on these metabolite concentrations.

Anemia is a common and progressive clinical manifestation of myelofibrosis that may occur as part of the disease pathogenesis as well as due to the myelosuppressive effects of some treatments, with a substantial impact on quality of life, prognosis, and healthcare resource utilization. Despite these burdens, anemia management has traditionally been a secondary priority to spleen and symptom control, due in part to the limitations of available therapeutic approaches. With the initial regulatory approvals of momelotinib, a Janus kinase 1 (JAK1), JAK2, and activin A receptor type 1 inhibitor that provides anemia-related benefits in addition to addressing splenomegaly and symptoms, re-evaluation of anemia as an early and prominent treatment consideration is warranted.
