Deciphering Nucleotides

Nucleotides are compounds made up of purine/pyrimidine bases, deoxyribose/ribose, and phosphoric acid. There is one phosphate group that exists in nucleoside monophosphate (NMP). The 5'-nucleotide phosphate group can be further phosphorylated to generate nucleoside diphosphate (NDP) and nucleoside triphosphate (NTP), and the phosphate groups are linked by high-energy bonds.

Biological Background of Nucleotides

Nucleotides are the precursors of biological macromolecules DNA, RNA, and participate in the heredity, developmental, and growth activities of organisms as the constituent parts of nucleic acids. In addition, many nucleotides are involved in various important biological functions, such as adenosine triphosphate (ATP), coenzymes, and others related to energy metabolism. Some nucleotide derivatives can interfere with nucleotide metabolism and have broad application prospects as anticancer drugs.

Key Technologies

We deploy integrated chemical and enzymatic methodologies to advance nucleotide synthesis. Our platform synthesizes nucleotides through solution-phase and solid-supported techniques. A pivotal innovation involves single-step condensation reactions that circumvent conventional multi-step synthetic routes. This approach utilizes specialized reagents to construct sugar-nucleotides from commercial precursors with exceptional regioselectivity.

Biocatalytic transformations further expand our capabilities. While typically restricted to natural substrates, our enzymatic processes enable gram-scale nucleotide production. We integrate high-concentration multi-enzyme cascades with selective precipitation purification, a chromatography-free strategy optimized for industrial-scale throughput. This synergistic fusion of chemical precision and enzymatic efficiency empowers us to tackle diverse nucleoside analogs and synthetically challenging targets.

Workflow

• Substrate Preparation

Prepare nucleoside and sugar substrates by dissolving them in appropriate buffers (e.g., phosphate buffer) at optimal concentrations, ensuring purity through filtration or chromatography if necessary.

• Enzyme Selection and Activation

Select specific glycosyltransferases or nucleotidyltransferases (depending on the target nucleoside-sugar) and activate them by reconstituting in a buffer with cofactors to initiate catalytic activity.

• Reaction Mixture Setup

Combine the prepared nucleoside, sugar, activated enzyme, and cofactors in a reaction vessel, adjusting pH and temperature to match the enzyme's optimal conditions.

• Incubation and Monitoring

Incubate the mixture under controlled conditions to allow the enzymatic reaction, where the sugar moiety is transferred to the nucleoside. Monitor progress periodically using analytical techniques to track product formation.

• Reaction Termination

Stop the reaction once the desired yield is achieved by methods such as heat inactivation, adding denaturing agents, or adjusting pH to extremes.

• Purification of Product

Separate the nucleoside-sugar product from unreacted substrates, enzymes, and by-products using purification steps like column chromatography, solvent extraction, or precipitation.

• Characterization and Quantification

Confirm the identity and purity of the purified nucleoside-sugar using spectroscopic methods and quantify the yield via HPLC with a standard curve or UV-visible spectroscopy.
