Hydrogen sulfide (HS) is an endogenous gasotransmitter with cardioprotective and antiviral effects. In this work, new cysteine-selective nucleoside-HS-donor hybrid molecules were prepared by conjugating nucleoside biomolecules with a thiol-activatable dithioacetyl group. 5'-Dithioacetate derivatives were synthesized from the canonical nucleosides (uridine, adenosine, cytidine, guanosine and thymidine), and the putative 5'-thio metabolites were also produced from uridine and adenosine.

Purpose: To investigate the presence of uridine-5'-triphosphate (UTP)-activated P2Y1-like nucleotide receptors (P2Y2R, P2Y4R, and P2Y6R) in conjunctival goblet cells (CGCs) and determine if they increase intracellular Ca2+ concentration ([Ca2+]i) and induce mucin secretion.
Methods: Adult, male rat conjunctiva was used for culture of CGCs. To investigate the expression of P2YRs, mRNA was extracted from CGCs and used for reverse transcription PCR (RT-PCR) with commercially obtained primers specific to P2Y2R, P2Y4R, and P2Y6R.

The emergence of RNA viruses driven by global population growth and international trade highlights the urgent need for effective antiviral agents that can inhibit viral replication. Nucleoside analogs, which mimic natural nucleotides, have shown promise in targeting RNA-dependent RNA polymerases (RdRps). Starting from protected 5-iodouridine, we report the synthesis of -substituted-(1,3-diyne)-uridines nucleosides and their phosphoramidate prodrugs.

mRNA therapeutics offer a potentially universal strategy for the efficient development and delivery of therapeutic proteins. Current mRNA vaccines include chemically modified nucleotides to reduce cellular immunogenicity. Here, we develop an efficient, high-throughput method to measure human translation initiation on therapeutically modified as well as endogenous RNAs.

Objective: To study the efficacy and safety of the use of high (200 mg) doses of uridine monophosphate in combination with choline (dietary supplement, dietary supplement, Neururidine N) in the treatment of patients with nonspecific back pain.
Material And Methods: An open observational study was conducted, which included 101 patients with acute PB; group 1 included 65 patients who received Neurouridine N (1 caps/day) meloxicam (7.5-15 mg/day) and meloxicam (7.
