Abstract:
본 발명은 플라반(flavan)계 화합물 또는 이의 약학적으로 허용가능한 염을 유효성분으로 함유하는 갱년기 증후군 또는 골다공증의 예방 및 치료용 약학적 조성물에 관한 것으로, 본 발명의 플라반계 화합물은 에스트로겐 수용체에 대한 에스트로겐 수용체 유전자 전사활성이 있고, 에스트로겐 수용체와의 리간드 결합활성을 나타내며, 에스트로겐 민감성 유방암 세포를 농도 의존적으로 세포증식을 유도함으로써 에스트로겐 활성을 나타낸다. 상기와 같이 에스트로겐 활성이 에스트로겐 수용체 알파(ER-α)보다 에스트로겐 수용체 베타(ER-β)에서 더 선택적인 활성을 나타내기 때문에 부작용이 경감된 식물성 에스트로겐으로서, 갱년기 증후군 또는 골다공증 예방 및 치료에 유용하게 이용될 수 있다.
