Abstract :

Hypoxia is a common feature associated with many types of cancer. Insufficient oxygenation state intensifies genome instability, promotes progression, enables avoidance of the immune response, and takes part in developing more aggressive phenotypes resistant to chemotherapy, radiotherapy, and photodynamic therapy. The activity of the hypoxiainducible factor, the critical element of response and adaptation to hypoxia, enhances cancer hallmarks such as suppression of the immune response, altered metabolism, angiogenesis, invasion and metastasis, and more. Although the HIF transcriptional factor is an intensively researched target of antitumor therapy, currently used agents target it indirectly (through topoisomerase I, mTOR, HSP90, etc.). The new inhibitors, PT2385, and PT2977 are first-in-class compounds targeting HIF directly. Moreover, they target isoform HIF2╔?, which is believed to maintain chronic hypoxia that characterizes advanced tumors. This poster briefly summarizes basic knowledge about hypoxia in cancers and activity of the hypoxia-inducible factor, shows structures of the new agents and discrepancies between their activity and previously used inhibitors. The poster also includes the preliminary results of PT2385 clinical trials and the schedule of the next planned clinical trials. This poster aims to signal the appearance of the new approach in the field of inhibiting the hypoxia-inducible factor.
