Staurosporine(星孢菌素)是一种由链霉菌Streptomyces staurospores产生的生物碱,最初是作为抗真菌剂使用的。Staurosporine是一种广谱性的蛋白激酶抑制剂,可以抑制蛋白激酶C(PKC)、cAMP依赖性蛋白激酶(PKA)、磷酸激酶、核糖体蛋白S6激酶、表皮生长因子受体(EGF-R)激酶和Ca2+/钙调蛋白依赖性蛋白激酶II(钙/钙调PKII)。Staurosporine对PKC的抑制作用是最强的(IC50 = 2.7 nM)。Staurosporine对一些哺乳动物的肿瘤细胞系表现出很强的细胞毒性,诱导细胞凋亡,抑制裂殖酵母在细胞分裂后的伸长。

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: | |
细胞系 |
A31、CHO-KDR、Mo-7e和A431细胞系 |
溶解方法 |
在DMSO中的溶解度 |
反应条件 |
24 h;IC50=0.08 mM(A31细胞系)、IC50=0.30 mM(Mo-7e细胞系)、IC50=1.0 mM(CHO-KDR细胞系)。 |
应用 |
在A31、Mo-7e和CHO-KDR细胞系中,staurosporine分别抑制血小板衍生生长因子(PDGF)、干细胞因子c-Kit和VEGF(KDR)诱导的受体自磷酸化,IC50值分别为0.08 mM、0.30 mM和1.0 mM。而在A431细胞系中,staurosporine不影响胰岛素、IGF-I或表皮生长因子(EGF)诱导的受体自磷酸化。 |
动物实验: | |
动物模型 |
无胸腺裸鼠 |
剂量 |
75 mg/kg/day;口服给药 |
应用 |
Staurosporine(75 mg/kg/day p.o.)完全抑制VEGF,而非bFGF诱导的血管生成反应。因此,staurosporine除了直接抑制肿瘤细胞增殖(通过其对PKCs的效应),还可以通过抑制肿瘤血管生成(通过其对VEGF-R酪氨酸激酶的效应),从而抑制肿瘤生长。该抗血管生成效应可能有助于抗肿瘤转移及广泛的抗肿瘤活性,正如staurosporine及其与细胞毒性剂的协同作用。 |
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。 |
