Nucléosides

<p>5-Methylcytidine is a nucleoside that is found in DNA and RNA. It is used in structural biology to probe the structure of DNA. 5-Methylcytidine binds to the enzyme methyl transferase, which catalyzes the transfer of a methyl group from S-adenosylmethionine to produce 5-methyluridine. This reaction occurs in long-term toxicity studies using primary cells, such as lymphocytes and fibroblasts. 5-Methylcytidine has been shown to inhibit tumour growth in mice by binding to nuclear dna polymerase and blocking transcription. The binding site for this drug on the polymerase is located at the same site as that for nucleoside analogues like azidothymidine (AZT) and zidovudine (AZT).</p>

<p>N2-DMF-5'-O-DMT-2'-O-methylguanosine is a novel nucleoside analog that has antiviral, anticancer and immunomodulating properties. It is synthesized from 2′,3′-dideoxyadenosine 5′-monophosphate by the condensation of 2,6-dimethylaniline with methylguanosine 5′-monophosphate and 5,6-dimethylaniline. The modification of the guanine base in N2-DMF-5'-O-DMT-2'-O-methylguanosine to an O6 -methyl group results in increased affinity for the ribonucleotide reductase enzyme (RNR) and inhibition of DNA synthesis.</p>

<p>3'-O-Methyluridine is a nucleoside that is used in the preparation of oligonucleotides and as a substrate for uridine phosphorylase. It is used to study the termination of RNA synthesis, which occurs when there are no more ribose residues in the RNA template strand. When this happens, an adenosine residue is added by polyphosphate kinase to the 3' end of the RNA strand. This addition causes a release of pyrophosphate and leads to end of DNA synthesis. The acid hydrolysis technique can be used to separate 3'-O-methyluridine from other nucleotides. This reaction produces guanosine, which can be detected using polymerase chain reaction (PCR) techniques such as polyacrylamide gel electrophoresis (PAGE).</p>

<p>Polyinosinic acid-polycytidylic acid (Poly I:C), an agonist of TLR3 toll-like receptors, is a synthetic double-stranded RNA analog, consisting of polyinosinic acid (poly I) paired with polycytidylic acid (poly C), forming a stable duplex structure. PolyI:C stimulates the secretion of pro-inflammatory cytokines and type I interferon through its interaction with endosomal Toll-like receptor 3 (TLR-3) and the cytoplasmic receptors melanoma differentiation-associated gene 5 (MDA-5) and retinoic acid-inducible gene I (RIG-I). This immunostimulant activity makes Poly I:C a useful vaccine adjuvant and is used in vaccine formulations.  Poly I:C and its stabilized analogs (e.g., poly-ICLC) are also being actively researched for their dual role in oncology: directly targeting tumors and acting as immune potentiators. For example Poly I:C can induce apoptosis in tumor cells and stimulate immunogenic cell death and is therefore being explored alongside chemotherapy, radiotherapy, and checkpoint inhibitors, helping to overcome resistance mechanisms and strengthen treatment outcomes. We can supply PolyI:C to all stages of your project - from R&amp;D and preclinical phases right up to GMP commercial manufacture.
