The invention concerns novel substituted bicyclic pyrazolo pyrimidine compounds of formula (I) having antiviral activity, in particular, having an inhibitory activity on the replication of the respiratory syncytial virus (RSV). The invention further concerns the preparation of such novel compounds, compositions comprising these compounds, and the compounds for use in the treatment of respiratory syncytial virus infection.
The present invention provides a 4-aminoquinazoline derivative having the chemical structure of the following formula, and the use thereof. It is demonstrated by the pharmacological experiment that, the compound or a salt thereof according to the present invention not only has distinct inhibitory effect on histone deacetylases, but also has stronger differentiation induction and anti-proliferative activities for certain tumor cells. It can be used in the treatment of cancers and diseases related to cell differentiation and proliferation. Excellent efficacy is observed especially for leukemia and a solid tumor. As demonstrated by the animal test, the compound or a salt thereof according to the present invention is less toxic.
Fibroblast growth factor receptors (FGFRs) are important oncology targets due to the dysregulation of this signaling pathway in a wide variety of human cancers. We identified a series of pyrazolylaminoquinazoline derivatives as potent FGFR inhibitors with low nanomolar potency. The representative compound 29 strongly inhibited FGFR1-3 kinase activity and suppressed FGFR signaling transduction in FGFR-addicted
