Nucleosides & 2′-Deoxynucleosides

Nucleosides are the basic building blocks of nucleotides and nucleic acids (RNA and DNA). A nucleoside consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a nitrogen-containing nucleobase. The nucleobases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the nucleobase uracil (U) replaces thymine. DNA and RNA molecules are polymers made up of long chains of nucleosides. Nucleosides have diverse functions in cellular processes, well beyond their role as building blocks of nucleic acids. They play critical roles in biological energy storage and transmission, signaling, regulation of various aspects of metabolism, and even as important antioxidants and enzyme cofactors. Moreover, nucleosides and their derivatives have significant therapeutic applications. Many antiviral and anticancer drugs are nucleoside analogs that interfere with nucleic acid synthesis in pathogens or cancer cells. Nucleoside analogs can inhibit DNA or RNA replication, making them valuable in the treatment of viral infections and certain types of cancer. To learn more about nucleoside products and services, please contact the experts at CASSIA, LLC.

Description: 2-Amino-2′-deoxyadenosine (n2dA) has been identified in the genomes of globally widespread bacterial viruses, such as Acinetobacter phage SH-Ab 15497, Cyanophage S-2L, and Vibrio phage PhiVC8. In bacteriophages, 2′-deoxyadenosine (dA) is completely replaced by n2dA, thus forming three hydrogen bonds with thymidine (dT). These non–Watson-Crick base pairs in the DNA are believed to help bacteriophages escape DNA degradation by bacterial restriction enzymes. (Science 2021, 372, 512-516.)

Custom Synthesis Options

CASSIA, LLC has many years of experience in nucleoside production. We offer high efficiency enzymatic synthesis production of nucleosides as our primary method, affording milder reaction conditions, simple operation, high reaction specificity, few side reactions, and simple isolation and purification of reaction products. In the process of nucleoside production, we continually optimize our protocols to provide customers with the best production service. We have successfully developed a range of synthetic routes for the production of nucleoside analogs, enabling rapid and efficient synthesis of modified nucleoside analogs and their derivatives. CASSIA, LLC has built a well-equipped lab and employs skilled researchers and partners that ensure we have the ability to provide high-quality results at an affordable price.

Applications:

  • Nucleosides can be used as feedstock for the production of antiviral and anticancer agents.
  • Custom isotope labeled nucleosides can support analytical efforts and data analysis in genomics.
  • Synthetic nucleosides drive mRNA-based vaccine innovation, improving immunization strategies.
  • Enzymatic synthesis of nucleosides is less toxic which might help in drug discovery and development.

CASSIA, LLC aims to offer excellent custom nucleoside synthesis proposals for our clients. Our professional R&D team generates custom synthesis proposals for our clients according to their requirements, and we aim to meet our client’s needs beyond what they expected. Please explore some examples of available custom isotopomers CASSIA, LLC can prepare. If you are interested in our services, please feel free to contact us.
