(methylsulfinyl)thymine (4) was inactive as an antiviral agent. The 5'-phosphates of these three thymidine derivatives were relatively potent inhibitors of thymidylate synthetase (Ki values range from 7.8 to 1.9 microM). It is improbable that the inhibition of this enzyme accounts for the anti-herpes activity of compounds 3 and 5.
用甲基硫基(3)和甲基磺酰基(5)取代胸腺嘧啶的α位可得到抗病毒剂,它们是单纯疱疹病毒在细胞培养中复制的特异性和相对无毒的抑制剂。硫醚(3)对1型和2型单纯疱疹病毒均有效,而砜衍生物(5)的活性仅限于1型单纯疱疹病毒。亚砜衍生物1-(2-deoxy-beta-D -核呋喃糖基)-α-(甲基亚磺酰基)胸腺嘧啶(4)作为抗病毒剂无效。这三种胸苷衍生物的5'-磷酸是胸苷酸合成酶的相对有效抑制剂(Ki值范围为7.8至1.9 microM)。这种酶的抑制不可能解释化合物3和5的抗疱疹活性。
