b-uridine

Uridine (Uridin) is a nucleoside compound, one of the four bases that make up RNA, that replaces thymine in DNA during transcription and pairs with adenine.

Cytidine (Cytosine-1-β-D-ribofuranoside) is a pyrimidine nucleoside comprised of a cytosine bound to ribose via a beta-N1-glycosidic bond. Cytidine is a precursor for uridine. Both cytidine and uridine are utilized in RNA synthesis.

3'-Azido-3'-deoxy-beta-L-uridine is a nucleoside derivative.

Carbetimer is a partially imidized copolymer of ethylene & maleic anhydride with average MW approx 1,200 daltons; capable of specific stimulation of immune response. Carbetimer is a low molecular weight polymer derived from ethylene and maleic anhydride with potent antineoplastic activity. Preclinical studies have shown antitumor effects against many tumor cell lines including B 16 melanoma. Its antitumor actions are felt to include both reduction of uridine and cytidine nucleoside triphosphate as well as the diminution of pyrimidine salvage by inhibiting uridine, cytidine, and thymidine kinase. Besides direct antiproliferative effects, Carbetimer could act through immunomodulation, as suggested by the induction of cytotoxic T-cells in mice and the discordant in vitro and in vivo activities against the Lewis lung carcinoma model.

2'-b-C-Methyl-6-azauridine is a Nucleoside Derivative - 6-Aza-uridine; 2'-Modified nucleoside.
