Nucleoside & Nucleotide Modification Service
Biological Significance of Modification of Nucleoside & Nucleotide
Modification of nucleosides and nucleotides is pivotal in the functional regulation of cells and life activities. The function of DNA and RNA can be modulated by changing their structure and introducing different chemical groups. Such modifications are essential to the process of drug discovery and development. For example, by targeting specific nucleotide modifications, researchers can design drugs with specific biological activities to inhibit the growth of pathogens or treat certain genetic diseases. Modifications such as glycosylation, phosphorylation, and acetylation can change nucleotide molecule charge state and structure thus impacting signaling pathways The techniques of nucleotide modification can also be used for gene editing. By modifying nucleotide molecules, researchers can design and develop nucleic acid sequences with specific functions for editing or repairing a patient's genes, which is important for several inherited diseases.

Workflow
Our modification service follows a meticulous, multi-step workflow to ensure the successful and efficient synthesis of custom-modified nucleosides and nucleotides.
- Consultation and Design
Our expert team collaborates with you to define the exact modification, target molecule, and application. We review the synthesis feasibility and provide a detailed project plan and quote.
- Synthetic Pathway Development
Based on your requirements, we design or optimize a synthetic route. This involves selecting the appropriate starting materials, reagents, and reaction conditions to achieve the desired modification with high yield and purity.
- Synthesis and Purification
Our skilled chemists execute the multi-step synthesis. Each step is monitored to ensure high conversion and minimize side reactions. The crude product is then rigorously purified using advanced techniques like HPLC to isolate the target modified nucleoside or nucleotide.
- Derivatization and Quality Control
The purified modified nucleoside or nucleotide can be further derivatized into a phosphoramidite for solid-phase oligonucleotide synthesis or into a triphosphate for enzymatic applications. The final product is subjected to comprehensive quality control using mass spectrometry, NMR, and HPLC to confirm its structure and purity.

Results: This review explores the applications of nucleobase-modified nucleosides and nucleotides—analogs lacking conventional hydrogen-bonding groups. The author details their use as mechanistic probes to study DNA polymerase activity and fidelity, revealing that hydrogen bonding is not essential for replication and highlighting roles for desolvation, shape complementarity, and π-stacking. The article further discusses their application in synthetic biology for expanding the genetic code beyond natural base pairs (e.g., Ds:Px pair) and creating novel aptamers. Finally, it covers their therapeutic potential, particularly in cancer treatment, where analogs like 5-nitroindole derivatives can inhibit translesion DNA synthesis (TLS) and enhance the efficacy of DNA-damaging agents like temozolomide.
