Description of IU1

IU1은 세포 투과성이 있는 가역적인 선택적 프로테아좀 저해제로 USP14에 대한 IC50 값이 4.7μM이다. IU1은 USP14의 촉매 간극에 결합하고 효소 활성을 차단함으로써 USP14를 저해한다. 배양된 세포를 IU1로 처리하면 신경 퇴행성 질환과 관련된 여러 프로테아좀 기질의 분해가 강화된다[1-2].

IU1(25μM) 처리는 ZO-1 발현을 조절함으로써 배양된 Bend.3 세포에서 OGD에 의해 유도된 내피 세포 누출을 완화할 수 있다[3]. IU1(100μM; 8시간)에 의해 USP14 활성이 저해되면 위암 세포 MKN74의 생존율이 현저히 감소하고 그들의 이동 및 침입 능력이 억제된다[4]. IU1(1-100μM; 24시간)은 ML1 세포의 증식 및 이동을 용량 의존적으로 현저한 감소시킨다[5].

IU1(400μg/kg; i.p; 3회)은 USP14를 저해함으로써 혈액뇌장벽의 완전성을 보호하고 신경염증을 완화하고 회복을 촉진한다[3]. IU1(p.o; 40mg/kg/일; 14일)에 의해 USP14가 고갈되면 쥐에서 간세포암(HCC) 세포의 성장이 억제된다[6]. IU1(400μg/kg; i.p; 7일) 처리는 허혈성 뇌졸중으로 인한 신경세포 손상을 완화했고 IU1 처리된 쥐에서 생존률 증가, 뇌경색 부피 감소 및 신경세포 손실 감소로 나타났다[7].

Protocol of IU1

세포 실험 [1]:

세포 라인

Bend.3 세포

제조 방법

세포는 트랜스웰 삽입구의 상단 챔버에 삽입되었습니다. OGD 처리와 IU1 처리 후 상단 챔버에 300μg/mL FITC-덱스탄산을 추가했습니다. 15분 후 하부 챔버에서 시료를 수집하고 추가 분석을 위해 사용되었습니다.

반응 조건

25μM

응용 분야

IU1 처리는 Zonula occludens 1 (ZO-1) 발현을 조절함으로써 배양된 Bend.3 세포에서 산소-포도당 박탈(OGD)에 의해 유도된 내피 세포 누출을 완화할 수 있습니다.

동물 실험 [2]:

동물 모형

중뇌동맥 막힘 상태의 수컷 성체 ICR 쥐 모델(MCAO)

제조 방법

체중 400μg/kg의 IU1을 복강 주사했습니다. 첫 번째 IU1 복강 주사는 MCAO 재관류 직후에 이루어졌고 나머지 두 번의 투여는 각각 허혈성 뇌졸중 후 24시간과 48시간에 투여했습니다.

제형

400μg/kg; i.p; 3 번

응용 분야

IU1은 MCAO 후 혈뇌장벽(BBB)의 완전성을 보호하고 누출을 줄였습니다.
