This modification increases the stability of this nucleoside in aqueous solutions and provides potent antiviral and anticancer activity.</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. 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>

<p>Acetyl hypoxanthine is an inorganic compound that has a cyclophosphate group. It can be synthesized from the reaction of acetic acid and 6-chloropurine, which is activated with trifluoroacetic acid and irradiated with ultraviolet light. Acetyl hypoxanthine can then be synthesized by ammonolysis of chloroacetone using ammonia or by chlorinating acetylene with chlorine. The advantages of this compound are its high yield and low cost.</p>

<p>Broad-spectrum anti-viral; inhibitor of HCV NS5B RNA polymerase</p>

<p>8-Chloroadenosine is a potent inhibitor of apoptosis, which is the process by which cells die. It has been shown to inhibit cell growth in murine hepatoma cells and synergize with other cytotoxic agents. 8-Chloroadenosine inhibits the activity of bcl-2 protein and thus blocks the release of cytochrome c from mitochondria. This causes DNA damage by inhibiting DNA synthesis and protein synthesis, leading to apoptosis. 8-Chloroadenosine has also been shown to be an active inhibitor of cancer cells, especially myeloma cell lines. The response element for 8-chloroadenosine is located in the promoter region of the gene encoding cyclooxygenase 2 (COX-2), which encodes a protein that produces prostaglandins involved in inflammation and tumor growth. The concentration of camp in cancer tissues determines whether these cells will respond favorably or unfavorably to this drug.</p>

<p>2'-O-Methyladenosine (2'-OMeA) is a nucleoside that is a low-energy analog of adenosine. It has been shown to be an effective inhibitor of protein synthesis in vitro, by inhibiting RNA polymerase in the process of transcription. 2'-OMeA has also been shown to inhibit virus replication in vitro and to have potent inhibitory activity against human immunodeficiency virus type 1 (HIV-1). 2'-OMeA inhibits viral replication by binding to the viral ribonucleotide reductase enzyme and blocking the conversion of ribonucleotides into deoxyribonucleotides. The chemical structures of 2'-OMeA are similar to those found in fatty acids and can be detected using chemical ionization mass spectroscopy. The sequence for 2'-OMeA was determined through sequencing methods including NMR spectroscopy and nuclear magnetic resonance data analysis.</p>

<p>8-Hydrazinoadenosine is an inhibitor of phosphodiesterase, which is a key enzyme in the regulation of cellular processes. 8-Hydrazinoadenosine binds to the active site of the enzyme and inhibits its function. This binding prevents hydrolysis of the phosphate bond between two nucleotides and so prevents the formation of a new nucleotide from a nucleoside and a phosphate molecule. 8-Hydrazinoadenosine has been shown to inhibit phosphodiesterases in vitro and in animals, including rat brain and mouse lung. Strategies for 8-hydrazinoadenosine commercialization have been investigated, including attaching it to other molecules that are more easily absorbed by cells or using irradiation to produce 8-aminoadenosine, which can be converted into 8-hydrazinoadenosine.</p>
