一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。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。 |
Rottlerin is a specific PKC inhibitor, with IC50 values for PKCδ of 3-6 μM, PKCα,β,γ of 30-42 μM, PKCε,η,ζ of 80-100 μM[1].
Rottlerin (20 μM, 2/6/24 hours) dramatically decreases the cyclin D-1 mRNA levels in a time-dependent manner and exhibits cell proliferation in HMVEC[2].
In Balb C nude mice, rottlerin (20 mg/kg, gavage 5 days per week, once daily, for 6 weeks) inhibits AsPC-1 pancreatic tumor growth with no toxicity. Rottlerin inhibits tumor cell proliferation, and induces apoptosis through activation of caspase-3 and cleavage of poly(ADP-ribose) polymerase (PARP)[3].

细胞实验[1,2]: | |
细胞系 | 大鼠(C6)和两种人神经胶质瘤(T98G和U138MG)细胞,神经胶质细胞,大鼠肺微血管内皮细胞,大鼠原发性肺动脉内皮细胞 |
溶解方法 | 该化合物在DMSO中的溶解度大于10 mM。若获取更高浓度的溶液,可在37℃下孵育10分钟,随后在超声波浴中摇匀。-20℃以下可储存数月。 |
反应条件 | 24 h |
应用 | Rottlerin(24小时)降低了C6、T98G和U138MG细胞的生长,C6的IC50为12 μM,T98G和Ui 38MG的IC50为大于20 μM,Rottlerin(48h)降低了C6、T98G和Ui38MG细胞的生长,IC50分别为5、7和9 μM,Rottlerin(5 μM)显著降低C6、T98G和U138MG中S期细胞的数量。在C6细胞中,Rottlerin导致细胞质空泡的积累和细胞组分在膜内的包装。在HL-60人白血病细胞中,Rottlerin(5 μM)产生明显的DNA梯度,Rottlerin以剂量依赖的方式显著增加大鼠LMVEC和PAEC中的基底内皮单层通透性,Rottlerin引起肌动球蛋白丝和局灶粘连中断。 |
动物实验[2]: | |
动物模型 | 成年雄性Sprague-Dawley大鼠 |
给药剂量 | 腹腔注射,50 mg/kg |
应用 | 在用不同浓度的Rottlerin处理的动物中,观察到EBD外渗的剂量反应。Rottlerin促进大鼠肺水肿。在麻醉大鼠中,Rottlerin通过独立于静水压变化破坏内皮屏障功能引起肺水肿。 |
注意事项 | 由于实验环境的不同,实际溶解度可能与理论值略有不同,请测试室内所有化合物的溶解度。 |
