As an extension of our previous work we tried to elucidate whether the presence of the cytidine component is necessary for cytostatic activity. In this context we have synthesized similarly structured nucleoside-phospholipid conjugates containing nucleoside components other than cytidine, which also do not exhibit cytostatic properties as such. The compounds include 5'-alkyldiphosphates and 5'-alky
最近的研究表明,具有结构上修饰的脂质部分的胞苷5'-二磷酸二酰基甘油的膦酰基类似物(CDP-DAG)在体外具有抗增殖活性。作为我们以前工作的扩展,我们试图阐明胞嘧啶核苷成分的存在对于细胞抑制活性是否必要。在这种情况下,我们合成了类似结构的核苷-磷脂缀合物,其包含胞苷以外的核苷成分,它们也没有表现出细胞抑制特性。该化合物包括具有不同烷基链长的2'-脱氧胞苷,胸腺嘧啶和腺苷的5'-烷基二磷酸和5'-烷基磷酸膦,以及选择的3-十六烷基-2-氯-2-脱氧甘油-(1)-二磷酸和-磷酸磷酸酯。这些核苷中。通过快速原子轰击(FAB)和电喷雾电离(ESI)质谱确认了新合成的核苷-磷脂缀合物的化学结构。已经发现这些化合物也抑制不同人细胞系的细胞生长,即胞苷成分的存在不是这些核苷-磷脂缀合物的抗增殖活性的必要先决条件。
