Abstract:
본 발명은 HIF-1 활성을 저해하는 화합물 및 이를 유효성분으로 함유하는 약학적 조성물에 관한 것이다. 본 발명에 따른 화합물은 비선택적인 세포 독성에 의해 항암 활성을 나타내는 것이 아니라, HIF-1α 단백질의 축적을 선택적으로 저해하고 신생 혈관 생성 인자(VEGF)의 활성을 효과적으로 저해하므로, 항암제, 당뇨병성 망막증 및 관절염 치료제의 유효성분으로 사용될 수 있다.
Abstract:
PURPOSE: A pharmaceutical composition containing a novel deguelin derivative or a pharmaceutically acceptable salt thereof is provided to selectively suppress HIF-1alpha accumulation and VEGF activation. CONSTITUTION: A pharmaceutical composition for preventing or treating cancer contains a compound of chemical formula 2 or a pharmaceutically acceptable salt thereof. The cancer is caused by HSP90 accumulation. A pharmaceutical composition for preventing or treating diabetic retinopathy contains a compound of chemical formula 2 or a pharmaceutically acceptable salt thereof.
