2-O-Methylguanosine丨CAS 2140-71-8

2-O-Methylguanosine (CAS 2140-71-8) is a naturally occurring modified nucleoside commonly found in transfer RNA (tRNA) and ribosomal RNA (rRNA). Its primary applications include use as a biochemical research reagent, a structural probe in RNA studies, and a building block in the synthesis of oligonucleotides. In molecular biology, it is applied in studies of RNA modification, translation fidelity, and ribosome function. Additionally, it is useful in the development of synthetic RNA molecules and nucleic acid-based therapeutics, where incorporation of 2-O-methyl modifications enhances RNA stability and resistance to enzymatic degradation.

The benefits of 2-O-methylguanosine arise from its structural and biochemical properties. The 2-O-methyl modification stabilizes RNA by increasing resistance to ribonucleases, thereby extending the half-life of synthetic oligonucleotides and RNA-based drugs. It also plays a key role in regulating RNA-protein interactions and ensuring proper folding and functionality of RNA molecules. In therapeutic and diagnostic applications, incorporation of such nucleoside analogs improves efficacy, safety, and stability of RNA constructs, making them more suitable for clinical use.
