The Synthesis and Glycoside Formation of Polyfluorinated Carbohydrates

Chemical Reviews, Год журнала: 2022, Номер 122(20), С. 15503 - 15602

Опубликована: Май 25, 2022

Fluorinated carbohydrates have found many applications in the glycosciences. Typically, these contain fluorination at a single position. There are not involving polyfluorinated carbohydrates, here defined as monosaccharides which more than one carbon has least fluorine substituent directly attached to it, with notable exception of their use mechanism-based inhibitors. The increasing attention carbohydrate physical properties, especially around lipophilicity, resulted surge interest for this class compounds. This review covers considerable body work toward synthesis hexoses, pentoses, ketosugars, and aminosugars including sialic acids nucleosides. An overview current state art glycosidation is also provided.

Synthesis of Fluorinated Nucleosides/Nucleotides and Their Antiviral Properties

Molecules, Год журнала: 2024, Номер 29(10), С. 2390 - 2390

Опубликована: Май 19, 2024

The FDA has approved several drugs based on the fluorinated nucleoside pharmacophore, and numerous are currently in clinical trials. Fluorine-containing nucleos(t)ides offer significant antiviral anticancer activity. insertion of a fluorine atom, either base or sugar nucleos(t)ides, alters its electronic steric parameters transforms lipophilicity, pharmacodynamic, pharmacokinetic properties these moieties. atom restricts oxidative metabolism provides enzymatic metabolic stability towards glycosidic bond nucleos(t)ide. incorporation also demonstrates additional hydrogen bonding interactions receptors with enhanced biological profiles. present article discusses synthetic methodology activities FDA-approved ongoing fluoro-containing nucleos(t)ide drug candidates

Chemistry, Год журнала: 2025, Номер 7(1), С. 7 - 7

Опубликована: Янв. 13, 2025

Fluorinated nucleos(t)ide drugs have proven to be successful chemotherapeutic agents in treating various cancers. The Food and Drug Administration (FDA) has approved several that fit within the fluorinated nucleoside pharmacophore, many more are either preclinical development or clinical trials. addition of fluorine atoms nucleos(t)ides improves metabolic stability glycosidic bond and, certain instances, facilitates additional interactions nucleons(t)ides with receptors. insertion on sugar base proved enhance lipophilicity, pharmacokinetic, pharmacodynamic properties. Overall, atom feeds diverse advantages biological profile analogs by improving their drug-like properties therapeutic potential. This review article covers often-used fluorinating reagents chemistry, significance [18F]-labeled nucleosides, synthesis anticancer activity FDA-approved fluoro-nucleos(t)ide drugs, as well candidates, which at stages agents.

Light‐ and Water‐Driven Nanoarchitectonics of Amphiphilic Azobenzene Derivatives: Photoswitching and Self‐Aggregation Dispersion Studies

ChemPhotoChem, Год журнала: 2025, Номер unknown

Опубликована: Май 30, 2025

Herein, how aggregation‐dispersion behavior of fluorinated azobenzene derivatives 5 and 6 with an amphiphilic dodecaoctane substituent is affected by UV light irradiation water described. The influence fluorine substituents on their photophysical properties, photoswitching differences, aggregation in waterin‐ground trans excited cis ‐state studied. Their properties are investigated under the polar MeOH nonpolar solvent benzene it found that shows different as compared to both solvents. Further, check MeOH, a competing added. It observed MeOH–H 2 O solution (0.9‐1.5 mL), compounds show redshift decrease absorbance, fluorescence emission found. dynamic scattering opposite behavior, initially macromolecular aggregated state ‐states but addition disperses solution. However, uniform micromolecular features further after water. Scanning electron microscopy images suggest patterns change morphology when added IR, 1 H, 19 F NMR done understand site intermolecular interactions.

Objectives: The present study aimed to provide an insight into the acute toxicity of a novel fluorinated nucleoside analogue (FNA), FNC (Azvudine or2'-deoxy-2'-β-fluoro-4'-azidocytidine). showed potent anti-viral and anti-cancer activities approved drug for high-load HIV patients, despite, its being lacking. Materials Methods: OECD-423 guidelines were followed during this parameters divided four categories - behavioral parameters, physiological histopathological supplementary tests. included feeding, body weight, belly size, organ weight mice behavior. consisted blood, liver, kidney indicators. In hematoxylin eosin staining was performed analyse histological changes in organs after exposure. addition, tests conducted assess cellular viability, DNA fragmentation cytokine levels (IL-6 TNF-α) response FNC. Results: induced mice-to-mice interaction activities. Mice's size remained unchanged. Physiological blood that increased level WBC, RBC, Hb, neutrophils decreased % count lymphocytes. Liver enzymes SGOT (AST), ALP increased. renal function test (RFT) cholesterol significantly decreased. Histopathological analysis kidney, brain, heart, lungs, spleen no sign tissue damage at highest dose 25 mg/kg b.wt. Supplementary cell viability change footprint, through our recently developed dilution cum-trypan (DCT) assay, Annexin/PI. No or apoptosis observed DAPI AO/EtBr studies. Pro-inflammatory cytokines IL-6 TNF-α dose-dependent manner. Conclusion: This concluded is safe use though higher concentration shows slight toxicity.
