The present invention relates to compounds of formula (I):
wherein R1 is C1-6alkylamino, or C1-6alkoxy; R2 is a group having the structure:
n is an integer having a value of 1 to 6; Het is a 6-membered saturated heterocycle containing one nitrogen atom wherein Het is attached to the —(CH2)n— moiety at any carbon atom of the heterocycle; R3 is hydrogen, C1-8alkyl, or C3-7cycloalkylC0-6alkyl; and salts thereof are inducers of human interferon. Compounds which induce human interferon may be useful in the treatment of various disorders, for example the treatment of allergic diseases and other inflammatory conditions for example allergic rhinitis and asthma, the treatment of infectious diseases and cancer, and may also be useful as vaccine adjuvants.
本发明涉及公式(I)的化合物:其中R1为C1-6烷基
氨基或C1-6烷氧基;R2是具有结构的基团:n为1至6的整数;Het是含有一个氮原子的6元饱和杂环,其中Het连接到杂环的任何碳原子处于—(
CH2)n—基团上;R3为氢、C1-8烷基或C3-7环烷基C0-6烷基;以及其盐是人类干扰素的诱导剂。诱导人类干扰素的化合物可以用于治疗各种疾病,例如过敏性疾病和其他炎症性疾病,例如过敏性鼻炎和哮喘,感染性疾病和癌症的治疗,也可以作为疫苗佐剂有用。
