A series of 5-alkyl-2'-deoxyuridine 3',5'-cyclic monophosphates (5-R-cdUMP's, R = Et, i-Pr, n-Pr, n-Bu, n-Pent, n-Hex, n-Oct) was prepared and tested in culture systems as antitumor and antiviral agents in comparison to the 5-alkyl-2'-deoxyuridines (5-R-dUrd's) themselves. Only the 5-Et- and 5-n-Bu-cdUMP showed appreciable cytostatic activities against murine L1210 and human lymphoblast Raji cells
一系列5-烷基-2'-脱氧尿苷3',5'-环一磷酸酯(5-R-cdUMP's,R = Et,i-Pr,n-Pr,n-Bu,n-Pent,n-Hex,与5-烷基2'-脱氧尿苷(5-R-dUrd's本身)相比,制备并在培养系统中测试了n-Oct)作为抗肿瘤和抗病毒剂。仅5-Et-和5-n-Bu-cdUMP对鼠L1210和人淋巴母细胞Raji细胞表现出明显的细胞抑制活性(ID50范围:28-82微克/ mL)。5-Et-dUrd本身更具活性(ID50 = 1.6和2.9微克/ mL)。5-i-Pr-和5-n-Bu-dUrd处于非活性状态,但对于链长为五个碳或以上的基团,活性再次提高。5-Et-cdUMP和5-Et-dUrd对脱氧胸苷激酶缺陷型(TK-)L1210和Raji细胞的活性大大降低。在涉及TK细胞的情况下,5-Et-cdUMP显然不是相应5'-单磷酸的有效前药来源。在5-R-cdUMP中
