Review, Journal: Nucleoside analogs for management of respiratory virus infections: mechanism of action and clinical efficacy. (Pubmed Central) - Nov 22, 2022 Besides, we outline how nucleoside analogs interact with the polymerases of respiratory viruses, to cause lethal virus mutagenesis or disturbance of viral RNA synthesis. In this way, we aim to convey the key findings on this rapidly evolving class of respiratory virus medication.

Journal: Nitro-Activated Nucleobase Exchange in the Synthesis of 2'-Fluoro-2'-Deoxyribonucleosides. (Pubmed Central) - Jul 20, 2022 Under Vorbrüggen conditions, 5-nitrouracil serves as the leaving nucleobase and enables exchange with pyrimidine and purine nucleobases to anomeric 2'-fluoro-2'-deoxyribonucleosides in favor of β-anomers generally. The strategy is also applied in the isotopic labeling of 2'-fluoro-2'-deoxyuridines.

P=N/A, P3 FNC cured the COVID-19 disease in almost all patients and showed better therapeutic efficacy than remdesivir. In this Account, we provide an overview of 4'-modified nucleoside analogs in clinical stages for antiviral therapies, highlighting the drug discovery strategies, structure-activity relationship studies, and preclinical/clinical studies and also give our perspectives on nucleoside-based antiviral drug discovery.

On the other hand, all combinations between fusion inhibitors showed antagonistic effects against RSV in vitro, with volume of antagonism ranging from -50 µM % to -176 µM % at 95% confidence interval. Over all, our results suggest the potentially therapeutic combinations in combating RSV in vitro could be considered for further animal and clinical evaluations.
