Abstract: Disclosed herein are an HIF-1 inhibitor, a method for the preparation thereof, and a pharmaceutical composition comprising the same as an active ingredient. The HIF-1 inhibitor shows anticancer activity thanks to the inhibition activity against HIF-1, a transcription factor which plays an important role in the growth and metastasis of cancer, but not to general cytotoxicity. Thus, the HIF-inhibitor and a pharmaceutically acceptable salt thereof can be used as a therapeutic for various cancers such as liver cancer; stomach cancer and breast cancer. Also, the compound having inhibition activity against HIF-1 is useful in the treatment of diabetic retinopathy and arthritis, which are aggravated by HIF-1-mediated VEGF expression.

Abstract: The present invention relates to a use of ZFP91 based on the functions of ZFP91 (Zinc Finger Protein 91) and the interaction of ZFP91 with NF-?B (Nuclear factor kappa B) signal transduction pathway proteins, more precisely a method to inhibit the activation of NF-?B alternative pathway by regulating ZFP91 activation, to inhibit tumor growth by inhibiting the transcription factor HIF-1 (hypoxia inducible factor-1) activation, to inhibit cancer malignancy by inhibiting angiogenesis, or reversely a method to increase the activation of NF-?B alternative pathway or to increase angiogenesis by increasing activation of HIF-1. The method of regulating ZFP91 activation of the present invention can increase or reduce HIF-1? stability by increasing or reducing the activation of NF-?B alternative pathway, so that it can be effectively used for the development of an anticancer agent, a therapeutic agent for arthritis, a therapeutic agent for ulcerative colitis, an anti-inflammatory agent and an angiogenesis inducer.
