Description of 666-15

666-15은 선택적인 사이클릭 AMP 반응 요소 결합 단백질(CREB) 억제제로 IC50 값이 0.081±0.04μM이다. 666-15는 또한 내원성 CREB 타겟 유전자의 표현을 억제하고 즉 핵 수용체와 관련된 단백질 1(Nurr1/NR4A2)의 전사 수준[1]을 억제한다. CREB은 다양한 세포외 신호(성장 인자와 호르몬 포함)에 의해 활성화 될 수 있는 핵 전사 인자이다[2]. 666-15는 렙토포토시스의 특이하고 효과적인 억제제인 괴사증 억제제 1(nec-1)의 신경 보호 효과를 차단한다[3].

체외 실험에서 새끼쥐 심장근세포(NRCMs)에 666-15(1µM)를 2시간 처리하여 페닐레프린 유도된 CREB 인산화를 효과적으로 억제했고 p38 인산화에는 현저한 영향이 없었다[4]. 노령 기니피그 연골세포에 666-15(0-500nM)를 처리하여 p-CREB1의 단백질 수준을 현저하게 낮추고 세포 활성을 증가시켰다[5]. 다른 전사 인자로 전사된 HEK293T 세포에 666-15(0-10µM)를 5-7시간 처리하고 Gal4-MLL, Gal4-c-Myb, Gal4-TEAD4/YAP1 그리고 혈청 반응 인자(SRF)에 의한 유전자 전사는 매우 작거나 억제되지 않았음을 보였다[6].

체내 실험에서 666-15(10mg/kg)을 삼음성 유방암(TNBC) 세포를 이식한 쥐에게 복강 내 주사로 투여하고 유방암의 성장을 억제했다. 도세타젤(DOC)과의 복용은 더 좋은 효과를 보여주었고 쥐의 체중에 현저한 영향을 미치지 않았다[7].

Protocol of 666-15

세포 실험 [1]:

세포 라인

신생아 쥐 심장 근세포(NRCMS)

제조 방법

NRCMs는 페닐레프린(PE)(50μM)과 24시간 동안 공존시켜 심장세포 비대를 유도했습니다. PE 처리 전 NRCMs를 1μM SB 203580이나 1μM 666-15로 2시간 동안 사전 처리하여 p38이나 CREB57의 인산화를 억제했습니다.

반응 조건

1µM; 2시간 동안

응용 분야

666-15은 CREB 인산화를 효과적으로 억제했습니다. 그런데 666-15은 페닐레프린 유도된 p38 활성화에 현저한 영향을 미치지 않았습니다.

동물 실험 [2]:

동물 모형

누드 쥐

제조 방법

10만 개의 삼음성 유방암(TNBC) 세포가 구리개 쥐 양쪽의 네 번째 유방 지방 패드에 이식되었습니다. 종양이 형성된 후 쥐들은 4개 그룹으로 나뉘어 매주 복강 내 주사로 Vehicle, 도세타젤(DOC)(10mg/kg), 666-15(10mg/kg) 또는 두 가지 주입했습니다. 종양 크기는 매주 관철되었고 쥐가 사멸된 후 종양 이미지를 촬영했습니다.

제형

10mg/kg; i.p.

응용 분야

666-15만으로도 유방암의 성장을 효과적으로 억제할 수 있고DOC과 함께 사용하면 더 좋은 효과를 보이고 쥐의 체중에 현저한 영향을 미치지 않습니다.
