Abstract

HIF-2α is a transcription factor activated mainly in hypoxic condition known to play crucial roles in a wide variety of pathophysiological events including cancer, metabolic syndrome, arthritis etc. In this context, a number of N'-aryl isonicotinolyhydrazides, in which known pharmacophores are included, have been selected from commercial chemical library and tested for the inhibitory activities targeting HIF-2α in cultured HTB94 cell. HRE-luciferase and HIF-2α were introduced into the cell by transfection and adenoviri infection, respectively and the reporter gene assay discovered the potency of 2-hydroxy-1-naphthyl structure. Accordingly, the scaffold has been adjusted based on this structure and subjected to anti-HIF-2α activity test, identifying 2 compounds as HIF-2α inhibitors. The activities were confirmed by false positive test. This study has been performed via the convergence of biology and chemistry and the results may be useful for discovering novel inhibitors and HIF-2α biology studies, and contribute to the development of therapeutic agents.

HIF-2α는 저산소 조건에서 활성화되는 전사인자로 암, 대사증후군, 관절염, 간염 등의 발병 기전에서 핵심 역할을 한다고 보고된 바 있다. 이에 HIF-2α 저해제를 도출하고자 기존 약리활성 구조를 도입한 N'-arylisonicotinolyhydrazide를 골격으로 설정하고 화합물 라이브러리로부터 해당 화합물들을 선택하여 HIF-2α 저해활성을 측정하였다. 이를 위해 HRE-luciferase를 HTB-94세포에 transfection하고 아데노바이러스를 이용하여 HIF-2α를 세포 내로 도입하여 luciferase reporter gene assay를 수행하였다. 2-hydroxy-1-naphthyl 기를 포함한 화합물에서 저해활성이 발견됨에 따라 이 구조를 포함하는 골격을 다시 설정하고 해당 화합물들을 선정하여 활성을 측정하였다. 그 결과 HIF-2α 저해활성과 위양성 시험을 통하여 2 종의 HIF-2α 저해제를 도출하였다. 본 연구는 생물학과 화학의 융합연구로 수행되었으며 도출된 저해제는 후속 저해제 탐색 연구와 HIF-2α의 기능 연구에 활용될 수 있고 관련 질환의 치료제 개발에도 기여 할 것으로 사료된다.
