N4-Benzoyl-2'-deoxy-5'-O-DMT-2',2'-difluorocytidine 3'-CE phosphoramidite, also known as Gemcitabine 3'-CE phosphoramidite, is a nucleoside phosphoramidite used in oligonucleotide synthesis. A chemical oligonucleotide synthesis instead of an enzymatic one allows quick access to bespoke oligonucleotides of the desired sequence. Chemically synthesised oligonucleotide sequences are typically constructed in a 3’ to 5’ direction. Gemcitabine 3'-CE phosphoramidite has been used in the synthesis of an oligonucleotide by single replacement of cytidine for gemcitabine for use in gene silencing experiments.

N4-Benzoyl-2'-O-methylcytidine is a triester of cytidine that is used in various biochemical research applications. It is enzymatically synthesized from cytidine and benzoyl chloride. N4-Benzoyl-2'-O-methylcytidine has been shown to have the same electrophoretic mobility as 5-hydroxyl cytidine, but it does not react with hydroxylamine to produce the corresponding hydroxylated product.

7-Deaza-2'-deoxy-7-iodoguanosine is a purine nucleoside that is synthesized from guanosine and iodine. It is used as a marker in sequencing reactions because it can be easily detected by UV light at 254 nm. 7-Deaza-2'-deoxy-7-iodoguanosine can be synthesized using the following general equation:

2-Thiocytidine is a nucleoside that is an intermediate in the synthesis of thiamine. It has been shown to be effective in the treatment of prostate cancer cells, which may be due to its ability to inhibit protein synthesis. 2-Thiocytidine binds to the catalytic site of ribonucleotide reductase (RR) and inhibits the enzyme's activity, thereby inhibiting DNA synthesis. This drug also has been shown to inhibit crosslinking caused by UV light or other agents that generate reactive oxygen species. 2-Thiocytidine binds to the active site of RR and prevents the formation of the enzyme-substrate complex. This binding prevents reduction of ribose into ribonucleotides and inhibits DNA synthesis.
