Cytidine analogs

WebUck2 catalyzes the phosphorylation of uridine and cytidine and their respective synthetic analogues. 6 Previous studies have primarily focused on the ability of Uck2 to activate antitumor prodrugs and to regulate chemosensitivity in cancer cells. 8,9 Recently, some studies have begun to evaluate the potential prognostic value of Uck2. Cytidine (symbol C or Cyd) is a nucleoside molecule that is formed when cytosine is attached to a ribose ring (also known as a ribofuranose) via a β-N1-glycosidic bond. Cytidine is a component of RNA. It is a white water-soluble solid. which is only slightly soluble in ethanol.
