The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof. The formula I compounds inhibit tyrosine kinase activity of such as TrkA, TrkB, TrkC, Jak2, Jak3 and CK2, thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.
Provided herein are pharmaceutical agents useful for therapy and/or prophylaxis in a mammal, pharmaceutical composition comprising such compounds, and their use as menin/MLL protein/protein interaction inhibitors, useful for treating diseases such as cancer, including but not limited to leukemia, myelodysplastic syndrome (MDS), and myeloproliferative neoplasms (MPN); and diabetes.
The present invention provides a compound having antiviral effects, particularly having growth inhibitory activity on influenza viruses, a preferred example of the compound being a substituted 3-hydroxy-4-pyridone derivative prodrug having cap-dependent endonuclease inhibitory activity.
