Article Abstract
Inspired by Roush's pioneering work on rare sugars, we have developed a scalable, stereoselective, de novo synthesis of orthogonally protected C2-fluoro digitoxose and cymarose, utilizing Sharpless kinetic resolution and organocatalytic fluorination as key steps. The utility of this strategy is demonstrated by the synthesis of a fluorinated analogue of digoxin, which indicates the fluorine on the sugar ring may have a significant impact on biological activity.

Introduction: Mutations in SORL1, encoding the sorting receptor Sortilin-related receptor with A-type repeats (SORLA), are found in individuals with Alzheimer's disease (AD). We studied SORLA, carrying a mutation in its ligand binding domain, to learn more about receptor functions relevant for human brain health.
Methods: We investigated consequences of SORLA expression in induced pluripotent stem cell (iPSC)-derived human neurons and microglia, using unbiased proteome screens and functional cell assays.
Aim To compare the results of primary percutaneous coronary intervention (PCI) for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in patients who recently recovered from COVID-19 with those not previously infected with SARS-CoV-2; to establish prognostic criteria for PCI complications, including stent thrombosis and restenosis (ST and SR) and progression of ischemic heart disease, and to determine ways to prevent them.Material and methods In 2021, middle-aged patients admitted to the Baku Central Clinical Hospital with a diagnosis of acute coronary syndrome who underwent urgent myocardial revascularization using percutaneous balloon angioplasty of the occluded coronary artery (CA) with implantation of a second-generation intracoronary drug-eluting stent were divided into two observation groups: the main group of 123 patients who had COVID-19 in the previous 6 months, and the control group of 112 patients who were not previously infected with SARS-CoV-2. The immediate results of PCI were assessed according to the TIMI scale; complications were assessed both clinically, by the incidence of severe complications (major adverse cardiovascular events, MACE), and angiographically, by the incidence of early and late ST and SR, and de novo stenosis that developed during the two-year observation period.

Beyond their classical functions as redox cofactors, recent fundamental and clinical research has expanded our understanding of the diverse roles of nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) in signaling pathways, epigenetic regulation and energy homeostasis. Moreover, NAD and NADP influence numerous diseases as well as the processes of aging, and are emerging as targets for clinical intervention. Here, we summarize safety, bioavailability and efficacy data from NAD-related clinical trials, focusing on aging and neurodegenerative diseases.

The essential cofactor coenzyme A (CoASH) and its thioester derivatives (acyl-CoAs) have pivotal roles in cellular metabolism. However, the mechanism by which different acyl-CoAs are accurately partitioned into different subcellular compartments to support site-specific reactions, and the physiological impact of such compartmentalization, remain poorly understood. Here, we report an optimized liquid chromatography-mass spectrometry-based pan-chain acyl-CoA extraction and profiling method that enables a robust detection of 33 cellular and 23 mitochondrial acyl-CoAs from cultured human cells.

[2,1]-Azaboranaphthalenes represent unique boron-nitrogen (BN) isosteres of naphthalenes, attracting interest for the development of molecules with enhanced therapeutic potency. The existing synthetic strategies are generally two-component reactions with harsh conditions. Here we report an organocatalysed three-component modular synthesis of ring-fused BN isosteres and BN-2,1-azaboranaphthalenes following ring expansion of unstrained cyclic ketones (n = 4-8) via Wolff-type rearrangement.
