(S)-1-(2,3-Dihydroxypropyl)cytosine is the unprotected (S)-GNA (glycol nucleic acid) cytosine nucleoside: a cytosine joined at N1 to an acyclic (S)-2,3-dihydroxypropyl "glycol" backbone in place of a ribose or deoxyribose sugar. CHEMOS lists it as catalog CH70002 with CAS 55559-70-1, molecular formula C7H11N3O3, and molecular weight 185.18 (PubChem CID 11805434; InChIKey LTTDCEYZEHQDGW-YFKPBYRVSA-N).
This is the parent glycol-cytosine unit: protecting the base and differentiating the two backbone hydroxyls yields the (S)-GNA-C phosphoramidite used to add a GNA cytosine during solid-phase oligonucleotide synthesis. According to PubMed, glycol nucleic acid is an acyclic nucleic-acid analog joined by phosphodiester bonds that is incorporated into oligonucleotides via phosphoramidite chemistry, and an (S)-GNA nucleotide increases resistance to nuclease degradation while having little impact on duplex structure.

应用背景
- Parent (S)-GNA-C nucleoside: the plain glycol-cytosine unit from which the base-protected monomer and (S)-GNA-C phosphoramidite are prepared.
- Acyclic backbone unit: the (S)-2,3-dihydroxypropyl glycol replaces the sugar ring, the defining feature of a GNA nucleotide.
- Nuclease-resistance research: according to PubMed, (S)-GNA incorporation has been studied for increasing resistance to exonuclease/phosphodiesterase degradation in siRNA duplexes.

常见问题
How does an (S)-GNA cytosine differ from a normal cytidine?
In place of the ribose/deoxyribose sugar ring, the cytosine sits on an acyclic (S)-2,3-dihydroxypropyl (glycol) backbone. This is the defining feature of glycol nucleic acid (GNA), a simplified acyclic nucleic-acid analog joined by phosphodiester bonds.
What is this compound used to make?
It is the parent (S)-GNA cytosine nucleoside: protecting the base and differentiating the two backbone hydroxyls into dimethoxytrityl and phosphoramidite handles gives the (S)-GNA-C phosphoramidite used to add a GNA cytosine during oligonucleotide synthesis.
