Nucleosidi

L-Guanosine is an enantiomer of adenosine. It has been shown to be effective in the treatment of autoimmune diseases and viruses, such as HIV. L-Guanosine is activated by phosphorylation, which leads to its binding with DNA and inhibition of viral replication. L-Guanosine is also a potent inhibitor of mammalian cell proliferation. It binds to the enzyme adenosyltransferase, thereby inhibiting the production of nucleotides, which are necessary for DNA synthesis. This inhibition causes cell death due to lack of DNA synthesis and protein production.

7-Methyl-6-thioguanosine inner salt is a compound that inhibits the activity of creatine kinase and phosphatase, which are enzymes involved in energy metabolism. It also binds to actin filaments and prevents their depolymerization. The binding mechanism of 7-methyl-6-thioguanosine inner salt is believed to be due to its ability to form disulfide bonds with cysteine residues on the surface of the enzyme. This inhibition has been shown to reduce the ATP production in mammalian cells and has been used as a model system for studying cellular processes.

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&D and preclinical phases right up to GMP commercial manufacture. Contact our team for custom Poly I:C products.
