Nucleotide-Sugars & Nucleotide-Sugar Analogs

Nucleotide-sugars are the activated building blocks for the biosynthesis of carbohydrates, oligosaccharides, and glycan conjugates. Their metabolism is particularly well studied in yeast, fungal pathogens, and bacterial pathogens, such as Escherichia coli and Mycobacterium tuberculosis. These pathways are also studied in plants, but the enzymes involved are less well understood. Nucleotide-sugars act as glycosyl donors, forming components of the fungal and bacterial cell wall, serve as virulence factors, and modulate cell surface glycoprotein cellular activity. Furthermore, the alteration of oligosaccharide and glycan sequences have been studied in vaccines against bacterial or fungal infections, as well as, cancer. Considering the crucial roles nucleotide-sugars, oligosaccharides, and glycan conjugates are involved in, they are targets for drug development, and their analogs are potential inhibitors of these processes. Drug development requires efficient methods for the synthesis of oligosaccharides and nucleotide-sugar building blocks, as well as, modified structures as potential inhibitors. It also requires understanding the details of biological and chemical processes, as well as, the reactivity and reactions under different conditions.

Custom Synthesis Options

CASSIA, LLC has many years of experience in nucleotide-sugar production. We offer high efficiency enzymatic synthesis production of nucleotide-sugars 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 nucleotide-sugar production, we continually optimize our protocols to provide customers with the best production service. We have also successfully developed a range of synthetic routes for the production of nucleotide-sugar analogs, enabling rapid and efficient synthesis of modified nucleotide-sugar 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:

Nucleotide-sugars can be used as feedstock for the production of oligosaccharides and glycans.
Custom isotope labeled nucleotide-sugars can support analytical efforts and data analysis in genomics.
Synthetic nucleotide-sugars drive oligosaccharide-based vaccine innovation, improving immunization strategies.
Enzymatic synthesis of nucleotide-sugars is less toxic which might help in drug discovery and development.

CASSIA, LLC aims to offer excellent custom nucleotide-sugar 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.
