Cas no 68892-41-1 (5'-O-DMT-N2-ibu-dG)

5'-O-DMT-N2-ibu-dG is a protected deoxyguanosine derivative widely used in oligonucleotide synthesis, particularly in solid-phase phosphoramidite chemistry. The 5'-O-DMT (4,4'-dimethoxytrityl) group provides reversible protection for the 5'-hydroxyl, enabling controlled chain elongation, while the N2-ibu (isobutyryl) moiety safeguards the exocyclic amine, preventing unwanted side reactions during synthesis. This modification ensures high coupling efficiency and minimizes depurination risks. The compound is characterized by its stability under standard synthetic conditions and compatibility with automated DNA synthesizers. Its precise protective group strategy allows for efficient deprotection post-synthesis, yielding high-purity oligonucleotides. This makes it a reliable choice for research and industrial applications requiring sequence-specific DNA constructs.

Recent Advances in the Study of 5'-O-DMT-N2-ibu-dG and Its Chemical Properties

The compound 5'-O-DMT-N2-ibu-dG, with the CAS number 68892-41-1, has garnered significant attention in the field of chemical biology and pharmaceutical research. This modified deoxyguanosine derivative plays a crucial role in oligonucleotide synthesis, particularly in the development of therapeutic nucleic acids. Recent studies have focused on optimizing its synthesis, understanding its stability, and exploring its applications in drug discovery and development.

One of the key advancements in the study of 5'-O-DMT-N2-ibu-dG is the refinement of its synthetic pathways. Researchers have developed more efficient methods for introducing the isobutyryl (ibu) and dimethoxytrityl (DMT) protecting groups, which are essential for the compound's stability during oligonucleotide synthesis. These improvements have not only increased the yield but also reduced the formation of by-products, making the process more cost-effective and scalable for industrial applications.

In addition to synthetic improvements, recent research has delved into the compound's biochemical properties. Studies have shown that 5'-O-DMT-N2-ibu-dG exhibits enhanced resistance to nuclease degradation compared to its unmodified counterparts. This property is particularly valuable in the design of antisense oligonucleotides and siRNA therapeutics, where stability in biological environments is a critical factor for efficacy.
