Description of DPDPE

DPDPE는 선택적이고 항경련성인 δ-opioid 수용체(DOR) 작용제이다. DOR은 중추신경계에 주로 분포하는 G단백질 연결 수용체(GPCR)로 내인성 엔케팔린과 외인성 리간드의 진통 및 항우울 작용 등 다양한 생리적 효과를 매개한다[2]. DPDPE는 오피오이드 수용체 신호전달, 통증 경로 및 중독 메커니즘 관련 연구에 일반적으로 사용된다[3].

체외 실험에서 GRK2를 과발현하거나 녹다운한 HEK293 세포를 DPDPE(2μM)로 30분간 처리한 결과는 GRK2 과발현은 야생형 수용체의 내재화 및 후속 재활용을 촉진한 반면 GRK2 녹다운은 이러한 과정을 억제하였다[4]. HEK293 세포를 DPDPE(1μM)로 60분간 전처리하면 경미한 DOR 탈감작만을 유도했고 모네신 존재 하에서 현저하게 증가하였다[5]. 인간 DOR을 안정적으로 발현하는 CHO 세포(CHO/DOR)를 DPDPE(100nM)로 5-30분간 처리하면 Ser9에서 글리코겐 신타아제 키나아제-3β(GSK-3β)의 인산화를 신속하고 현저하게 유도하고 키나아제 활성의 현저한 억제(~35%)를 동반하였다[6].

체내 실험에서 스트렙토조토신(STZ)으로 유도된 당뇨병성 신경병증 쥐에 DPDPE(0.5, 1, 3, 5mg/kg)을 피하 주사한 후 30분에 기계적 통각 과민, 열 통각 과민 및 열 통각 과민을 용량 의존적으로 억제하였다[7]. Sprague Dawley 쥐에서 후지 압박 10분 전 척수강 내 DPDPE(100nM; 10μL) 전처리는 척수 배측각 I층에서 유해 자극에 의해 유도된 뉴로키닌 1 수용체(NK1R) 내재화를 현저하게 억제하였다[8].

Protocol of DPDPE

세포 실험 [1]:

세포 라인

DOR의 지속적으로 발현한 CHO세포 (CHO/DOR)

제조 방법

혈청 결핍 CHO/DOR 세포를 100nM DPDPE와 5-30분간 배양했습니다. 영 시간대 시료는 용매로 처리했습니다. 세포 추출물에서 인산화 GSK-3β(pGSK), 총 GSK-3β(GSK) 및 액틴 수준을 분석하였습니다.

반응 조건

100nM; 5-30 분 동안

응용 분야

DPDPE(100nM)로 CHO/DOR 세포를 처리하면 인산화-Ser9-GSK-3β 수준이 빠르게 증가해서 5분 후에 현저해지고10분에 정점에 도달하고 30분까지 기저 수준 이상을 유지했습니다.

동물 실험 [2]:

동물 모형

Sprague Dawley 쥐

제조 방법

쥐는 후지 압박 10분 전에 척수강 내 DPDPE(100nM; 10μL) 주사를 받았습니다. 쥐는 펜토바르비탈 나트륨으로 마취되었고 한쪽 후지가 6인치 비톱니 모기 집게의 턱에 수직으로 위치되었고 턱은 지혈기 라칫의 첫 번째 클릭까지 닫혔습니다. 압박은 60초 동안 가해졌습니다. 압박 후 5분에 쥐는 대동맥 관류로 고정되었고 척수는 NK1R 면역세포화학 분석을 위해 채취되었습니다.

제형

100nM; 10μL; i.t.

응용 분야

DPDPE 처리는 후지 압박 손상에 의해 유도된 척수 배측각 I층의 NK1R 내부화를 현저하게 억제하였습니다.
