A series of derivatives of 5-hydroxyalkylamino-1,3-oxazoles were synthesized. Among these derivatives, 5 compounds have been evaluated for their activities against a normal laboratory human cytomegalovirus (HCMV) strain, AD169, in human foreskin fibroblast (HFF) cells. Bioassays showed that among these, 2 compounds containing a remainder of glucamine exhibited moderate antiviral activity (compounds
合成了一系列5-羟烷基氨基-1,3-恶唑的衍生物。在这些衍生物中,已经评估了5种化合物在人包皮成纤维细胞(HFF)中对正常实验室人巨细胞病毒(HCMV)株AD169的活性。生物测定法表明,在其中的2种含有剩余葡糖胺的化合物中,抗病毒活性中等(化合物9和15,EC 50 = 5.42 µM,CC 50 > 150 µM,SI 50 > 28,EC 50 = 4.91 µM,CC 50 > 150 µM,SI 50 > 31)。这些化合物之间的区别在于,第一种在第4位包含一个邻苯二甲酰亚胺基团,在第5个位置包含磷酰基,而后者在相应的位置上包含一个苯基基团和一个氰基。但是, 在该试验中,它们的活性远远低于对照药物更昔洛韦(EC 50 = 0.32 µM,CC 50 > 150 µM,SI 50 > 476)。这些和先前获得的数据使我们可以考虑将1,3-恶唑用作合成具有抗HCMV活性的新化合物的有前途的骨架。
