1. CytArabine is converted to the triphosphate form within the cell and then competes with cytidine for incorporation

2. Sialyltransferase activity was estimated in serum samples of patients with cancer and controls using immobilized asialo-fetuin as the acceptor and cytidine-5′-monophospho [14C] sialic acid as the donor.

3. Cytosar, Udicil, Alexan, Cytarbel, Aracytin, Erpalfa, Aracytine, Arabine, TArabine Pfs, Cytosar-U, and Ara-Cell NCI Definition : An antimetabolite analogue of cytidine with a modified sugar moiety (arabinose instead of ribose)

4. Direct measurements of the ribonucleoside and deoxyribonucleoside triphosphate pool sizes have been made, and the pathways and rates of metabolism of adenine, hypoxanthine, guanine, guanosirae, deoxyadenosine, and deoxyguanosine and of uridine, cytidine, deoxyeytidine, deoxyuridine, and thymidine have been determined.

5. Serum-sialyltransferase activity was measured in serum samples of 116 patients with malignant tumors of various origins and different clinical stages using asialo-fetuin as the acceptor and cytidine-5′-mono-phospho[14C]sialic acid as the donor.

6. The mutual interactions of Gd(III)tetraphenylporphyrin (GdTPP), Gd(III)tetramethylpyridylporphyrin (GdTMePyP), and the free base tetramethylpyridylporphyrin (H2TMePyP) with some nucleic bases (adenine, thymine, uracil, and cytosine) and their N-glycoside derivatives (adenosine, thymidine, uridine, and cytidine) have been studied by spectrophotometric titration in mixed methanol-ammonia-water solutions.
