Phospholipase D from Streptomyces effectively catalyzed the transfer reaction of the phosphatidyl residue from 3-sn-phosphatidylcholine to the 5'-hydroxyl group of nuclesides in a two-phase system. Thus, a variety of 5'-(3-sn-phosphatidyl)nucleosides could be readily prepared in high yields by means of this reaction. Among them, phosphatidyl-FUR (3b), phosphatidyl-Ara FC (8b), and phoshatidyl-neplanocin A (12b) each produced a significant increase in the life span mice bearing i.p.-implanted P388 leukemia, being more effective than the parent nucleosides.
在两相体系中,链霉菌的磷脂酶 D 能有效催化 3-sn-磷脂酰胆碱的磷脂酰残基向核苷的 5'-羟基的转移反应。因此,通过该反应可以很容易地高产制备出各种 5'-(3-sn-磷脂酰基)核苷。其中,磷脂酰-FUR (3b)、磷脂酰-Ara FC (8b)和磷脂酰-去甲斑蝥素 A (12b)都能显著延长P388白血病小鼠的寿命,比母体核苷更有效。
