efficiently converted to their triphosphates for anticancer activity. Among all the synthesized purine nucleosides, adenine derivative 1b and N6-methyladenine derivative 3k showed potent anticancer activity, showing equipotent inhibitory activity as the positive control, neplanocin A (1a) or Ara-C. However, the phosphoramidate prodrug 3p showed less anticancer activity than 1b, indicating that it did not
基于6'-氟环戊烯基-胞嘧啶2b在IIa期临床试验中对吉西他滨耐药的胰腺癌的有效抗癌活性,我们对6'-氟环戊烯基-嘧啶3a - i和-嘌呤3j - o发现新的抗癌药。我们还合成了腺嘌呤衍生物1b的氨基磷酸酯前药3p,以确定抗癌活性是否取决于癌细胞中DNA和/或RNA聚合酶的抑制作用和/或S的抑制作用。-腺苷同型半胱氨酸(SAH)水解酶。所有合成的嘧啶核苷在体外均表现出比胞嘧啶衍生物2b低得多的有效抗癌活性,它们充当RNA和/或DNA聚合酶抑制剂,表明它们不能有效地转化为其三磷酸酯以具有抗癌活性。在所有合成的嘌呤核苷中,腺嘌呤衍生物1b和N 6-甲基腺嘌呤衍生物3k显示出有效的抗癌活性,并显示出作为阳性对照,neplanocin A(1a)或Ara-C的等效抑制活性。但是,氨基磷酸酯前药3p的抗癌活性低于1b,表明它不像2b那样起RNA和/或DNA聚合酶抑制剂的作用。该结果还表明1b的抗癌活
