Passage | Cell Cycle |
Background | Roscovitine is a potent and selective inhibitor of CDKs. |
Biological Activity | Roscovitine是有效,选择性的 CDKs 抑制剂,抑制 CDK5,CDK2 和 CDK2 的 IC50 分别为0.2 μM,0.65 μM,0.7 μM。[1-3] |
IC50 | cdc2/cyclin B:0.65μM;cdk2/cyclin A:0.7μM;Cdk2/cyclin E2:0.7μM;CDK5/p35:0.16μM;ERK2:14μM [1-3] |
In Vitro | Roscovitine对某些细胞周期蛋白依赖性激酶具有高效率和高选择性。用25种高度纯化的激酶(包括蛋白激酶A,G和C同种型,肌球蛋白轻链激酶,酪蛋白激酶2,胰岛素受体酪氨酸激酶,c-src,v-abl)研究Roscovitine的激酶特异性。 Roscovitine不会显著抑制大多数激酶。仅Cdc2,Cdk2和Cdk5基本上被抑制(IC50值分别为0.65,0.7和0.2μM)。 Roscovitine对Cdk4k和Cdk6的抑制作用很差(IC50>100μM)。细胞外调节激酶erk1和erk2分别被抑制,IC50分别为34μM和14μM。 Roscovitine抑制哺乳动物细胞系的增殖,平均IC50为16μM[1]。 Roscovitine降低了CDK5和p35的水平,同时上调了E-钙粘蛋白,但下调了波形蛋白和胶原蛋白IV。此外,Roscovitine抑制高葡萄糖培养的NRK52E细胞迁移和侵袭的能力[2]。 |
In Vivo | 与正常对照组相比,Roscovitine下调磷酸化ERK1/2和PPARγ伴随E-cadherin的增加,但Vimentin和Collagen IV减少。相应地,Roscovitine减少糖尿病大鼠的肾小管间质纤维化。 Roscovitine在糖尿病大鼠中通过ERK1/2 /PPARγ途径有效减少肾小管间质纤维化[2]。 Roscovitine(16.5 mg/kg)显著降低肿瘤生长速度并提高治疗小鼠的存活率。引人注目的是,Roscovitine治疗导致一只小鼠完全肿瘤消失(25%);此外,在完成治疗后5个月,未发现该小鼠的肿瘤再生长。用Roscovitine和对照小鼠治疗的小鼠之间小鼠体重没有显著差异,两组之间的行为差异也可以忽略不计。这些结果表明,Roscovitine可有效用作HPV +头颈癌的选择性肿瘤生长抑制剂[3]。 |
Cell Experiment | 使用大鼠肾小管上皮细胞(NRK52E)。 CDK5抑制剂Roscovitine(Ros .;10μM)和活化剂p35(15μM),PPARγ激动剂Rosiglitazone(Rosi .; 50nM)和ERK1/2抑制剂U0126(50nM)用于治疗NRK52E细胞。每组细胞处理72小时,然后收获进行进一步分析[2]。 |
Animal Experiment | 大鼠[2]雄性Sprague Dawley大鼠(6-8周龄)腹腔注射单次注射稀释于0.1M柠檬酸盐缓冲液pH4.5(糖尿病)或柠檬酸盐缓冲液(非糖尿病)的链脲佐菌素(65mg/kg)。在注射后三天,使用葡萄糖氧化酶法在葡萄糖分析仪上测定血浆葡萄糖浓度。葡萄糖水平超过16.7mM的大鼠被认为是糖尿病,因此包括在研究中。每周测量一次血浆葡萄糖水平。为了研究CDK5抑制对肾小管间质纤维化的影响,每天向糖尿病大鼠腹膜内注射Roscovitine(25mg/kg)直至处死。 DMSO作为对照包括在内。小鼠[3]将指数生长的UMSCC47细胞皮下注射到雌性NUDE小鼠的骶骨区域。每只小鼠用50%基质胶中的2×105个细胞和100μL体积的50%PBS接种。在肿瘤达到可测量的大小后,给予小鼠16.5mg/kg剂量的腹膜内Roscovitine或载体注射。监测体重,肿瘤生长和一般行为。每3天测量肿瘤体积。当肿瘤超过0.5cm 3时,处死小鼠。 |
