plasma half-life, and its use is associated with severe side effects. Fatty acyl derivatives of cytarabine were synthesized with the expectation to improve cellular uptake and generate derivatives with a longer duration of action. Multi-step protection and deprotection reactions of hydroxyl and amino groups and conjugation with a fatty acid (i.e., myristic acid and 12-thioethyldodecanoic acid) afforded
阿糖胞苷是一种化学治疗剂,主要用于治疗急性髓细胞性白血病和淋巴母细胞性白血病。阿糖胞苷是一种极性核苷,血浆半衰期短,其使用会带来严重的副作用。合成了阿糖胞苷的脂肪酰基衍生物,以期改善细胞摄取并产生具有更长作用时间的衍生物。羟基和氨基的多步保护和脱保护反应以及与脂肪酸(即肉豆蔻酸和12-硫代乙基十二烷酸)的缀合产生5'- O-取代,2'- O阿糖胞苷的-取代的和2',5'-二取代的脂肪酰基衍生物。孵育96小时后,发现阿糖胞苷的2',5'-二肉豆蔻酰基衍生物在1μM的浓度下可抑制CCRF-CEM细胞的生长约76%。
