Abstract

5-Alpha reductase II, which converts testosterone (T) to dihydrotestosterone (DHT), is a crucial enzyme II in benign prostatic hyperplasia. Inhibitory effects of Curcuma longa L. (CL) extracts on 5-alpha reductase II activity were investigated in rat prostate tissue homogenates as well as LNCaP cells expressing human 5-alpha reductase II. Hot water extract (CL-HW) of Curcuma longa L. significantly inhibited 5-alpha reductase activity by over 80% at a concentration of $100{\mu}g/mL$, whereas 20% ethanol extracts (CL-E20) of Curcuma longa L. exhibited significant inhibitory activity from $50{\mu}g/mL$. These results indicated that Curcuma longa L is a potent 5-alpha reductase II inhibitor for benign prostatic hyperplasia treatment.

본 연구에서는 울금(Curcuma longa L.)의 다양한 추출물을 대상으로 5-alpha reductase의 활성 저해 정도를 측정하였다. 5-Alpha reductase는 T에서 활성형 남성호르몬인 DHT로 전환을 담당하며, 전립선비대에서는 혈액에서 DHT 농도가 높다. Rat의 전립선조직 균질액과 5-alpha reductase를 과발현시킨 LNCaP 세포 균질액을 대상으로 측정한 결과, $100{\mu}g/mL$의 농도에서 울금의 열수추출물(CL-HW)과 20% 에탄올추출물(CL-E20)이 5-alpha reductase 활성을 효과적으로 저해하였다. 특히 CL-HW는 $100{\mu}g/mL$의 농도에서 80% 이상의 유의적 억제효과를 보였으며, CL-E20은 $50{\mu}g/mL$의 농도부터 80% 이상의 감소효과를 보였다. 이 같은 결과에서 CL-HW 및 CL-E20은 5-alpha reductase의 억제활성이 있으며, 이는 전립선비대 치료소재로 개발될 수 있는 가능성이 있음을 제안한다.
