Description of Mifepristone

Mifepristone (RU486)은 구복으로 효과적인 프로게스테론(PR) 수용체와 포니코코르티코이드 수용체(GR)와 앙티아고니스트로 유산 약으로 사용되고 체외 실험에서 IC50 값이 각각 0.2nM과 2.6nM이다. Mifepristone은 프로게스테론의 작용을 차단하는 항유전상호산제로 경부와 자궁의 혈관 확장과 자궁 수축을 유발한다 [2]. Mifepristone은 우울증 치료하고 신경인지 기능 개선와 기분 향상에도 사용할 수 있다 [3].

체외 실험에서 Mifepristone (20μM)으로 유방암 세포인 SK-OV-3, OV2008, IGROV-1, OV2008을 처리한 결과는 24시간 내에 세포 성장을 완전히 차단하고 이 효과는 3일 동안 지속되었다[4]. 사람 위암세포 MKN-45을 Mifepristone (5, 10, 20μM)으로 처리한 결과는 세포의 매트릭스 젤에 대한 이형성 접착을 농도 의존적으로 억제하고 세포 통합 효소 β3 표현을 하강시켰다[5].

인체 실험에서 C57BL/6 쥐에 Mifepristone (200 mg/kg)을 구강 투여하여 1주일 치료한 결과는 풍부한 환경(EE)에 의해 유발된 보조 림프조직(SLT)에서 CD4:CD8 T세포 비율의 감소를 완전히 차단했다[6]. 우울증 모델 쥐에 Mifepristone (25 mg/kg)을 하부 피하 주사로 14일 치료한 결과는 인터루킨 1β(IL-1β) 유발 우울증 같은 행동을 개선하고 미글리아 및 아스트로글리아 기능을 조절했다[7].

Protocol of Mifepristone

세포 실험 [1]:

세포 라인

SK-OV-3、OV2008、IGROV-1、OV2008 세포

제조 방법

다양한 유방암 세포 라인 (SK-OV-3, Caov-3, IGROV-1, OV2008)에 고정된 20μM 농도의 Mifepristone에 3일 동안 노출시키고 약물을 매 24시간마다 교체했습니다.

반응 조건

20μM; 72시간 동안

응용 분야

모든 세포 라인에서 20μM Mifepristone에 24시간 노출하는 것이 충분히 세포 성장을 억제할 수 있었고 효과는 3일 동안 지속되었습니다.

동물 실험 [2]:

동물 모형

수컷 C57BL/6 쥐

제조 방법

Mifepristone은 0.9% NaCl, 0.25% 카르복시메틸 셀룰로오스, 0.2% 튜엔 20에 녹여졌습니다. 수컷 C57BL/6 쥐는 풍부한 환경(EE)이나 통제 사양에 기르여 매일 구강 투여로 Mifepristone (200 mg/kg 체중)이나 차량 통제를 1주일 동안 받았습니다.

제형

200mg/kg; p.o.

응용 분야

Mifepristone은EE에 의해 유발된 보조 림프조직(SLT)에서 CD4:CD8 T세포 비율의 감소를 완전히 차단했습니다.
