It is a lead compound for the development of therapeutic agents for human immunodeficiency virus type 1 and varicella, and it has potential applications in the treatment of renal toxicity. 2dT inhibits viral replication by inhibiting viral thymidine kinase, which converts 2dT to 2'-deoxy-4'-thioguanosine monophosphate (2'TGMP). The 2'TGMP inhibits intracellular phosphorylation reactions necessary for DNA synthesis and cell division. This inhibition leads to death of the infected cells.</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 is a single stranded RNA analog which is combined with polycytidylic acid (poly C) to form a stable duplex structure known as Polyinosinic acid-polycytidylic acid (Poly I:C). 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. Contact our team for custom Poly I:C products.<br>For more on poly I:C read out blog 'Poly I:C: A Vaccine Adjuvant With Oncological Potential.'</p>
