Approaches to repurposing reverse transcriptase antivirals in cancer

British Journal of Clinical Pharmacology, EarlyView.
This review highlights the role of reverse transcriptase (RT) inhibition in cellular regulation associated with non‐terminal repeat retrotransposons and endogenous retroviruses. Based on their pleiotropic characteristics, RT inhibitors (RTIs) are discussed as potential anticancer agents.

N‐ to C‐Glycoside Rearrangement of Uridine 5′‐Phosphate in Two Enzymatic Steps for the Production of Pseudouridine 5′‐Phosphate

Biotechnology and Bioengineering, EarlyView.
The authors present a streamlined cascade reaction for one‐pot N‐C rearrangement of uridine‐5′‐phosphate (UMP) to pseudouridine‐5′‐phosphate (ΨMP; a key mRNA vaccine building block), in two enzymatic steps catalyzed by UMP nucleosidase (EC 3.2.2.10) and ΨMP C‐glycosidase (EC 4.2.1.70).

Immunosuppressive JAG2+ tumor‐associated neutrophils hamper PD‐1 blockade response in ovarian cancer by mediating the differentiation of effector regulatory T cells

Cancer Communications, EarlyView.
Abstract Background Tumor‐associated neutrophils (TANs) play a critical role in modulating immune responses and exhibit significant heterogeneity. Our previous study demonstrated that jagged canonical Notch ligand 2 (JAG2)+ TANs were associated with an immunosuppressive microenvironment in high‐grade serous ovarian cancer (HGSOC), but the underlying ...

Nucleophilic displacement reactions of 5′-derivatised nucleosides in a vibration ball mill

Beilstein Journal of Organic Chemistry, 2017
Vibration ball-milling in a zirconia-lined vessel afforded clean and quantitative nucleophilic displacement reactions between 4-methoxybenzylthiolate salts and nucleoside 5′-halides or 5′-tosylates in five to 60 minutes.

Enhancing antitumor immunity through the combination of cholesterolized TLR7 agonist liposomes and radiotherapy: a role for IL‐1β and the inflammasome pathway

Cancer Communications, EarlyView.
Abstract Background Radiotherapy (RT) is a key treatment modality in cancer therapy, utilizing high‐energy radiation to directly kill tumor cells. Recent research has increasingly highlighted RT's potential to indirectly enhance antitumor immunity. However, this immune activation alone often fails to generate sustained systemic antitumor responses.

Glycosylation reactions mediated by hypervalent iodine: application to the synthesis of nucleosides and carbohydrates

Beilstein Journal of Organic Chemistry, 2018
To synthesize nucleoside and oligosaccharide derivatives, we often use a glycosylation reaction to form a glycoside bond. Coupling reactions between a nucleobase and a sugar donor in the former case, and the reaction between an acceptor and a sugar donor

Effect of uridine protecting groups on the diastereoselectivity of uridine-derived aldehyde 5’-alkynylation

Beilstein Journal of Organic Chemistry, 2017
The 5’-alkynylation of uridine-derived aldehydes is described. The addition of alkynyl Grignard reagents on the carbonyl group is significantly influenced by the 2’,3’-di-O-protecting groups (R1): O-alkyl groups led to modest diastereoselectivities (65 ...
