Abstract: Isoxazole-3-carboxamide derivatives and their use in treating viral infections and diseases, such as diseases caused by viruses of the Picornaviridae family of viruses (e.g., rhinoviruses, enteroviruses, and coxsackieviruses) is described. The derivatives have good efficacy against a range of viruses, including pleconaril-resistant viral strains, and have low induction of cytochrome P4503A4 (CYP3A4).

Abstract: 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 RH, which has a Hammett constant ?p greater than 0.23. The present invention also concerns the method of its manufacture. For corresponding compounds, surprisingly a particularly 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.
