  • Patent number: 8314103
    Abstract: The present invention relates to pyridyl derivatives capable of inhibiting phosphatidylinositol-3-kinase (PI3k), mammalian target of rapamycin (mTOR) and/or hypoxia inducible factor 1? (HIF-1?) mediated signaling. Also disclosed are processes for preparation of the pyridyl derivatives, and their use in the manufacture of pharmaceutical compositions for the treatment of clinical conditions caused by deregulation of signaling pathways selected from one or more of PI3K, mTOR and HIF-1? pathways. The pyridyl derivatives are also useful for the treatment of conditions or disorders mediated by TNF-?.
