Biological Activity:NVP-BGT226 is a novel dual PI3K/mTOR inhibitor with an IC50 ~1 nM. In cellular assays it could produce nearly complete inhibition of PI3K signaling at low nanomolar (<50 nM) concentrations. Flow cytometric analysis revealed an accumulation of cells in the G0–G1 phase with a concomitant loss in the S-phase. TUNEL assay and the analysis of Caspase 3/7 and PARP indicated that BGT226 induced cancer cell death through an apoptosis independent pathway. BGT226 induced autophagy as indicated by the aggregation and upregulation of the microtubule-associated protein light chain 3B-II, and p62 degradation. It is in the phase I/II clinical trials for the treatment of advanced solid tumors.
How to Use:
- In vitro: BGT226 was used at 0.2 µM concentration in cellular assays to investigate its effects on the PI3K/AKT signaling pathways.
- In vivo: BGT226 was dissolved in 90% NMP/10% PEG300 and orally dosed at 5mg/Kg once a day.

1. 姜黄素是一个典型的HAT抑制剂。
2. 针对P300: 在大约10年前,Cole和他的同事设计出了一种p300/CBP抑制剂,发表在nature杂志上。
希望能帮到你,望采纳!
天然产物,大多都有颜色,
存在干扰,多数情况下需要做样品的阴性对照,
尽量能用荧光的方法,
之前我们做过,将两个试剂盒的方法合并后,做的,
效果还可以
支原体培养则是取样后在培养基上培养,看有多少支原体菌落会长出,是比较直观和可信的结果。
总体来讲,这两种检查手段可信度都较高,结合一起,不仅可以可靠的知道有无解脲支原体感染,还能知道感染是否严重。
