The present invention relates to 5-amino-3-phenylamino-6-phenylpyrazolo[3,4-d]pyrimidine derivatives of the general formula I
or pharmaceutically acceptable salts or propharmacons thereof, wherein at least one hydrogen atom in at least one of the phenyl groups A and B is substituted by a substituent R
H
, which has a Hammett constant σ
p
greater than 0.23. The present invention also concerns the method of its manufacture. For corresponding compounds, surprisingly a particuarly high activity against viruses, in particular rhinoviruses and picornaviruses was determined. Furthermore, the compounds are tolerated very well. For these reasons the compounds are suitable for the treatment of viral infections and as drugs.
本发明涉及一般式I的5-氨基-3-苯基氨基-6-苯基吡唑并[3,4-d]嘧啶衍生物或其药学上可接受的盐或前药,其中苯基A和B中至少一个苯基中的至少一个氢原子被具有Hammett常数σp大于0.23的取代基RH取代。本发明还涉及其制备方法。对应的化合物表现出出乎意料的对病毒,特别是鼻病毒和小RNA病毒的高活性。此外,这些化合物耐受性很好。因此,这些化合物适用于治疗病毒感染和作为药物。
