Entecavir Phosphoramidite
Entecavir Phosphoramidite is a modified phosphoramidite derived from Entecavir, a nucleoside analog commonly used as an antiviral drug for the treatment of chronic hepatitis B virus (HBV) infections. The phosphoramidite group at the 3' position allows for the incorporation of Entecavir into oligonucleotides during solid-phase synthesis. Entecavir itself is an oral antiviral medication that works by inhibiting the reverse transcriptase enzyme of HBV, thus preventing viral replication. When used as a phosphoramidite in oligonucleotide synthesis, Entecavir provides the ability to create modified oligonucleotides with specific antiviral properties or to facilitate antiviral research and development, including the design of antisense oligonucleotides or RNA-based therapeutics. This phosphoramidite can be used in therapeutic applications targeting HBV or in the development of tools for studying viral replication, antiviral resistance mechanisms, and other aspects of virology. It could also potentially be utilized in the design of oligonucleotides with specialized antiviral or gene-editing functions. Synonyms: Phosphoramidous acid, N,N-bis(1-methylethyl)-, (1S,2R,4S)-2-[[bis(4-methoxyphenyl)phenylmethoxy]methyl]-4-[1,6-dihydro-2-[(2-methyl-1-oxopropyl)amino]-6-oxo-9H-purin-9-yl]-3-methylenecyclopentyl 2-cyanoethyl ester. Grade: ≥97%. CAS No. 3054794-07-6. Molecular formula: C46H56N7O7P. Mole weight: 849.96.
