prototype compounds and particularly triesters 2c,d exhibited pronounced anti-EBV activity making these compounds promising candidates for further development. However, the 3'-ester derivatives were devoid of any antiviral activity while the 3'-aminoacyl derivatives showed an antiviral activity dependent upon the amino acid and the Calpha-configuration
关于其潜在的抗EBV活性,研究了新型cycloSal-BVDUMP三酯2-4 5-[((E)-2-溴乙烯基)-2'-脱氧尿苷(BVDU,1)。除了3'-未修饰的cycloSal-BVDUMP三酯2a-f外,3'-羟基官能团还被不同的脂肪族羧酸(3a-g)和具有天然和非天然Calpha-构型(4a- m)。除了这些化合物的合成以外,还将报道新衍生物的不同物理化学性质,即亲脂性和水解行为。可以证明,通过在pH 6.8和7.3的磷酸盐缓冲液以及P3HR-1细胞提取物中进行化学水解,可以从大多数化合物中释放出单磷酸盐BVDUMP而不是3',5'-环状BVDUMP。最后,测试了新化合物的抗EBV活性。结果,原型化合物,特别是三酯2c,显示出明显的抗EBV活性,使这些化合物有望成为进一步开发的候选物。但是,3'-酯衍生物没有任何抗病毒活性,而3'-氨基酰基衍生物显示出取决于氨基酸和Calpha-构型的抗病毒活性。
