The cytosine analogue of neplanocin A, cyclopentenylcytosine (CPE-C, 3), has significant antitumor and antiviral activity commensurate with the drug's ability to produce a significant depletion of cytidine triphosphate (CTP) levels that result from the potent inhibition of cytidine triphosphate synthetase. Another important antitumor agent, previously identified as a potent inhibitor of the same enzyme
Neplanocin A的胞嘧啶类似物,环戊烯基胞嘧啶(CPE-C,3)具有显着的抗肿瘤和抗病毒活性,与该药物产生的三磷酸胞苷三磷酸(CTP)水平显着降低的能力相称,这是由于三磷酸胞苷三磷酸合酶的有效抑制所致。另一种重要的抗肿瘤药是3-脱氮尿嘧啶核苷(2),以前被确定为该酶的有效抑制剂。进行了环戊烯基核苷3-deaza-CPE-C(5)和3-deaza-CPE-U(6)的合成,以研究修饰的3-deaza嘧啶糖苷配基糖苷对其生物活性的影响。父级CPE-C。这些化合物是通过相应的糖苷配基的钠盐在环戊烯-1-醇甲磺酸盐(10)上经SN2置换反应合成的。在每种情况下,在最终除去保护基之前,必须对相应的N和O烷基化产物进行分离和表征。目标化合物没有针对HSV-1和人类流感病毒的体外抗病毒活性。尽管3-deaza-CPE-C对培养的L1210细胞无毒,但3-deaza-CPE-U在体外对鼠L1210白血病表现出显着的细胞毒性。
