MK-0752是一种在临床开发上非常有效的γ分泌酶抑制剂,IC50值约为50 nM。γ分泌酶是Notch切割机制的重要组成部分,它可以催化受体蛋白跨膜结构域的切割。
Notch信号需要γ分泌酶来切割Notch,释放Notch的胞内结构域(NICD)从而激活靶基因的转录。Notch信号在正常组织发育、细胞命运决定、增殖和存活中起着重要作用。通过结合同源配体Delta1、Delta2、Delta3、Jagged1和Jagged2,Notch信号被激活。在体外,抑制Notch信号可以抑制BC细胞的增值。

一般建议 | 不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
细胞实验[1]: | |
细胞系 |
SH-SY5Y细胞 |
溶解方法 |
在DMSO中的溶解度>10 mM。为了获得更高的浓度,可以将离心管在37℃加热10分钟和/或在超声波浴中震荡一段时间。原液可以在-20℃以下储存几个月。 |
反应条件 |
IC50:5 nM |
应用 |
MK-0752是一种适度有效的γ分泌酶抑制剂。在人SH-SY5Y细胞中,MK-0752剂量依赖地抑制Aβ40的产生,IC50值为5 nM。 |
动物实验[1]: | |
动物模型 |
雄性CMP恒河猴 |
剂量 |
60 mg/kg和240 mg/kg;口服给药。 |
应用 |
MK-0752口服给药后剂量依赖地减少Aβ的水平。240 mg/kg的MK-0752处理48小时后,Aβ的水平仅恢复到基线水平的50%,而60 mg/kg治疗组在30小时之后Aβ的水平恢复到基线水平,而在治疗后的33-48小时,血浆Aβ水平出现反弹,高于基线水平。 |
注意事项 |
请测试所有化合物在室内的溶解度,实际溶解度和理论值可能略有不同。这是由实验系统的误差引起的,属于正常现象。 |
