A series of fluorine containing tricyclic analogues of acyclovir (ACV, 1) and ganciclovir (GCV, 2) were synthesized and evaluated for their activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) and cytostatic activity against HSV-1 thymidine kinase (TK) gene-transduced human osteosarcoma tumour cells. It was found that fluorine substitution reduced the antiviral activity, but most
合成了一系列含氟的阿昔洛韦(ACV,1)和更昔洛韦(GCV,2)的三环类似物,并评估了它们对1型单纯疱疹病毒(HSV-1)和2型单纯疱疹病毒(HSV-2)的活性以及细胞抑制活性抗HSV-1胸苷激酶(TK)基因转导的人骨肉瘤肿瘤细胞。发现氟取代降低了抗病毒活性,但是大多数新化合物是明显的细胞抑制剂,其效力和选择性类似于亲本ACV和GCV。化合物12、13和16有望作为标记的底物用于HSV TK-配体相互作用的(19)F NMR研究和/或监测表达HSV TK的细胞中其代谢产物。
