Description of GGsTop

GGsTop은 γ - 글루탐일 전펩티다제(GGT)의 불가역적 억제제(Ki = 170μM)이다. GGsTop은 GGT의 활성 부위에 공유 결합해서 촉매 활동을 억제해서 세포 내 환원 상태를 조절하고 아미노산 대사를 영향을 미치고 세포의 산화 - 환원 균형을 조절한다 [2 - 3]. GGsTop은 주로 간 손상을 완화하기 위해 사용된다 [4].

인간 치주인대 세포(hPLCs)에서 GGsTOP(0 - 50μM;7일)처리 후 hPLCs의 증식이 강화되었다 [5]. HCC - 1806 세포에서 GGsTOP(0.01 - 10000nM;4시간)처리 후 글루타치온 활성이 억제되었다 [6].

시클로포스파마이드 유도성 중성구 감소증 종양 쥐 모델에서 GGsTop(5mg/kg;복강 주사;6일)은 과립구 집락 자극 인자의 종양 성장 촉진 효과를 없애준다 [7]. 오타스카 롱 에반스 토쿠시마 지방(OLETF)쥐에서 GGsTop(1mg/kg;정맥 주사;단일 투여)는ALT、AST및γ - GT수준을 유의하게 감소시킨다 [8].

Protocol of GGsTop

세포 실험 [1]:

세포 라인

인간 치주인대세포 (hPLCs)

제조 방법

3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT)검사를 사용해서 인간 치주인대 세포(hPLCs)의 생존력이 측정되었습니다. 간단하게 hPLCs(2.5×10³ 세포/웰)을 96웰 판에 파종하고 부착하고 24시간 동안 자라게 하였습니다. 세포는 밤새 굶기고 그 다음 0, 5, 10, 20 또는 50μM GGsTOP과 1, 3, 5 및 7일 동안 배양되었습니다. 매일마다 교체되었습니다.그리고 20μl MTT를 각 웰에 추가하고 4시간 동안 세포를 배양하였습니다. 이 후에 배양액을 제거하고 각 웰에 150μl 디메틸술폰을 10분 동안 추가하였습니다.

반응 조건

0-50μM; 7일 동안

응용 분야

GGsTOP 처리 후 hPLCs의 증식이 강화되었습니다.

동물 실험 [2]:

동물 모형

시클로포스파마이드 유도성 중성구 감소증 종양 쥐 모델

제조 방법

EL4 림프종 세포(4×10⁵ 세포/쥐)를 C57BL/6J 쥐의 우측 하복부에 피하 주사하였습니다. EL4 세포 접종 후 7일째에 쥐는 앞에서 설명한 방법을 따라 중성구 감소증 쥐 모델을 생성하기 위해 CPA(100mg/kg)의 단일 복용량을 복강 주사하였습니다. 같은 날부터 실험용 쥐는 6일 연속 PBS, GGsTop(5mg/kg)및 재조합 과립구 집락 자극 인자(G-CSF, 200μg/kg)의 복강 주사를 받았습니다. 위의 시약 투여 전에 쥐 후안 혈액(약 75μL)을 매일 수집해서 Sysmex XT-2000i 자동 혈액 분석기를 사용해서 유동 세포 측정 분석과 혈구 수를 결정하였습니다.

제형

5mg/kg; ip; 6 일 동안

응용 분야

GGsTop은 G-CSF의 종양 성장을 촉진하는 효과를 폐지합니다.
