Cryptotanshinone (Tanshinone C)

中文名稱:隱丹參酮

Cryptotanshinone (Tanshinone C)是一種STAT3抑制劑,無細(xì)胞試驗(yàn)中IC50為4.6 μM,強(qiáng)烈抑制STAT3 Tyr705磷酸化,對(duì)STAT3 Ser727作用效果弱,對(duì)STAT1和STAT5沒有作用效果。Cryptotanshinone 可誘導(dǎo)ROS依賴的自噬和線粒體介導(dǎo)的凋亡。

常見問題及建議解決方法

問題 1:
I want to use this compound for my mouse in vivo experiment, so how to reconstitute it?

回答:
Cryptotanshinone can be dissolved in 2% DMSO/30% PEG 300/5% Tween 80/ddH2O at 2 mg/ml. But after stayed for about 0.5-1 hour, the precipitation went out. So if you are going to use this vehicle, it is recommended to be prepared just before use.
