A nucleic acid polymer comprising 8 to 50 nucleoside subunits linked by intersubunit linkages, wherein the nucleic acid polymer comprises (A) one or more 3'-5' thiophosphoramidate intersubunit linkage and the remaining intersubunit linkages are 3'-5' thiophosphate intersubunit linkages and/or (B) at least 40% of the nucleoside subunits contain a 2'-MOE substituent. Those nucleic acid polymers are useful in the treatment of a viral infection, more specifically Hepatitis B virus and/or Hepatitis D virus.
一种包含由互补亚单位连接的8至50个核苷酸亚单位的核酸聚合物,其中该核酸聚合物包括(A)一个或多个3'-5'
硫代
磷酰胺亚单位连接,其余的亚单位连接为3'-5'
硫酸酯亚单位连接和/或(B)至少40%的核苷酸亚单位含有2'-MOE取代基。这些核酸聚合物在治疗病毒感染中有用,更具体地是乙型肝炎病毒和/或丙型肝炎病毒。
