核酸関連化合物のうち,プリン・ピリミジン塩基類,ヌクレオシド類, 2'-及び3'-モノヌクレオチド類ポリヌクレオチド類には単独ではほとんどうま味がないが, 6-ヒドロキシプリン誘導体の5'-モノヌクレオチド類には独特の呈味作用があり,これら呈味ヌクレオチド類とL-グルタミン酸ナトリウムの間に味に関し顕著な特異的相乗作用がみとめられた.

Enzymatic selective dephosphorylation of 1-β-D-arabinofuranosylcytosine 3', 5'-diphosphate (1) with nuclease-3'-nucleotidase P1 at 60° for 24 hr gave 1-β-D-arabinofuranosylcytosine 5'-phosphate (Ara CMP) (2) in good yield. The acylation of both N4- and the 2', 3'-hydroxyl groups of 2 followed by coupling with various alcohols and phenols in the presence of 2, 4, 6-triisopropylbenzenesulfonyl chloride and subsequent alkaline hydrolysis afforded the title compounds (4). The resulting 32 kinds of Ara CMP alkyl or aryl esters were examined to determine their biological activities, such as antiviral activity against herpes simplex type 1 in cultured human embryonic lung fibroblast cells, growth inhibitory activity against mouse leukemic L5178Y cells in culture and antileukemic activity against L-1210 in mice. Ara CMP esters were active in these assay systems.
