The present invention relates to pyridyl derivatives capable of inhibiting phosphatidylinositol-3-kinase (PI3k), mammalian target of rapamycin (mTOR) and/or hypoxia inducible factor 1α (HIF-1α) 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-1α pathways. The pyridyl derivatives are also useful for the treatment of conditions or disorders mediated by TNF-α.

Hypoxia-inducible factor-1 alpha (HIF-1 alpha) is a critical regulatory protein of cellular response to hypoxia, and regulates the transcription of many genes involved in key aspects of cancer biology, including immortalization, maintenance of stem cell pools, cellular dedifferentiation, vascularization, and invasion/metastasis. HIF-1 alpha has been implicated in the regulation of genes involved in angiogenesis, for example, VEGF and is associated with tumor progression. In the last decade, over expression of HIF-1 alpha has been demonstrated in many common human cancers and emerging as a validated target for anticancer drug discovery. Here we report the discovery of newly designed and synthesized pyridylpyrimidine based potent and selective inhibitors of HIF-1 alpha. P2630 has been found as potent antiproliferative, antiangiogenic and orally efficacious compound in PC-3 xenograft mice model. (C) 2010 Elsevier Ltd. All rights reserved.
