研究了小檗碱化合物E6与钙调素(CaM)依赖性肌球蛋白轻链激酶(MLCK)的相互作用。实验结果表明,随着E6添加量的增加,对MLCK活性的抑制作用增强,过量添加CaM可完全克服对MLCK活性的抑制作用。随着化合物E6浓度的增加,CaM对MLCK的刺激活性逐渐被抑制,表明化合物E6对MLCK活性的抑制具有浓度依赖性;Ki为0.95微米。化合物E6使丹酚标记的CaM的荧光强度减弱,随着添加不同量的CaM,荧光强度逐渐增强。化合物E6对有限胰蛋白酶化产生的MLCK片段的活性没有影响,是一种新型且相当有效的钙调素拮抗剂。[1]

Our previous studies showed that the natural compound berbamine, from Chinese herb Berberis amurensis, selectively induces apoptosis of imatinib (IM)-resistant-Bcr/Abl-expressing leukemia cells from the K562 cell line and CML patients. Here, a series of new berbamine derivatives were obtained by synthesis. In this series, high to very high activity in vitro has been found. Compounds 2e, 2g, 3f, 3k, 3q and 3u exhibited consistent high anti-tumor activity for imatinib-resistant K562 leukemia cells. Their IC(50) values at 48h were 0.36-0.55 microM, whereas berbamine IC(50) value was 8.9 microM. Cell cycle analysis results showed that compound 3h could reduce G0/G1 cells. In particular, these compounds displayed potent inhibition of the cytoplasm-to-nucleus translocation of NF-kappaB p65 which plays a critical role in the survival of leukemia stem cells. These results suggest that berbamine could be a good starting point for the development of novel lead compounds in the fight against leukemia.[2]

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
