The new amphiphilic dinucleoside phosphate, 2′-deoxy-5-fluorouridylyl-(3′5′)-2′-deoxy-5-fluoro-N4-octadecylcytidine (4) was synthesized on a gram scale, using the phosphotriester method, starting from the cytostatic drug 2′-deoxy-5-fluorouridine (5FdU) and 2′-deoxy-5-fluoro-N4-octadecylcytidine (1d).

使用磷酸三酯法以克级合成了新的两亲性磷酸二核苷2'-脱氧-5-氟尿嘧啶-(3'5')-2'-脱氧-5-氟-N 4-十八烷基胞嘧啶核苷(4),从细胞抑制药物2'-脱氧-5-氟尿苷(5FdU)和2'-脱氧-5-氟-N 4-十八烷基胞苷(1d)开始。在使用人胰腺腺癌细胞系MIA PaCa 2进行的体外克隆形成生长测定中,两亲性二聚体比母体单体5FdU显着更有效。当以水溶液形式使用时,二聚体的IC 50为10μg/ ml,当以脂质体分散体形式给予时为12μg/ ml,而使用5FdU时,IC 50 在使用的浓度范围内未达到最大浓度。
