Passage | Cell Cycle |
Background | Palbociclib hydrochloride is a highly selective CDK4/6 inhibitor. |
Biological Activity | Palbociclib hydrochloride是高选择性的 CDK4/6 抑制剂,IC50 分别为11 nM 和 16 nM[1-3]。 |
IC50 | Cdk4/cyclin D3:9nM;Cdk4/cyclin D1:11nM;Cdk6/cyclin D2:16nM [1-3] |
In Vitro | 在WST-中,Palbociclib(PD)以浓度依赖性方式有效抑制MP-MRT-AN(AN),KP-MRT-RY(RY),G401和KP-MRT-NS(NS)细胞系。 8试验。 IC50分别为0.01μM,0.01μM,0.06μM和0.6μM。相反,KP-MRT-YM(YM)细胞系对Palbociclib具有抗性(IC50>10μM)。流式细胞仪结果显示浓度在0到1.0μM之间的Palbociclib以浓度依赖性方式诱导AN,RY,G401和NS细胞系中的G1停滞,但对YM细胞没有影响。 BrdU掺入结果与WST-8和流式细胞术结果一致:PD减少AN,RY,G401和NS细胞系中的BrdU掺入(表明G1停滞),但在YM细胞系中没有。 Palbociclib,即使浓度为0.05μM,也能显著降低AN,RY和G401细胞系中的BrdU掺入量(p <0.05)[2]。Palbociclib在MDA-MB-435乳腺癌细胞中减少Ser780处视网膜母细胞瘤(Rb)磷酸化的IC50为66nM。 Palbociclib在降低该肿瘤中Ser795的Rb磷酸化方面同样有效,IC50为63 nM,在Colo-205结肠癌中获得了与Ser780和Ser795磷酸化相似的作用[1]。 |
In Vivo | Palbociclib对多种人肿瘤异种移植模型显示出显著的抗肿瘤效力。在携带Colo-205结肠癌异种移植物(p16缺失)的小鼠中,每天用Palbociclib(150或75mg/kg)给药14天产生快速肿瘤消退和相应的肿瘤生长延迟~50天,肿瘤> 1log在测试的最高剂量下杀死细胞。在37.5mg/kg时,肿瘤在治疗期间缓慢退化。即使剂量低至12.5mg/kg,也可获得13天的生长延迟,表明肿瘤生长速率抑制率为90%。同样,在MDA-MB-435乳腺癌(p16缺失)中观察到强大的抗肿瘤活性,其中完全肿瘤停滞在150mg/kg时是明显的,并且在最高剂量下一些细胞杀伤是明显的[1]。 |
Cell Experiment | MRT细胞系,G401,MP-MRT-AN(AN),KP-MRT-RY(RY),KP-MRT-NS(NS)和KP-MRT-YM(YM)细胞系接种于正常生长培养基中进入96孔细胞板。 24小时后,用含有Palbociclib(0.05或1μM)或DMSO的培养基替换培养基。培养细胞并一式三份处理。使用细胞计数试剂盒-8通过WST-8测定在处理后8天测定细胞增殖。 |
Animal Experiment | 将小鼠(18-22g)随机化,然后皮下植入肿瘤碎片(30mg)到右腋窝区域。当肿瘤达到100至150mg时开始治疗。根据表中所示的方案和剂量给出PD 0332991(150或75mg/kg,口服),并通过管饲法给出图例,基于平均组体重,在乳酸钠缓冲液(50mM,pH4.0)中作为溶液。在所有实验中,对照组中有12只小鼠,处理组中各有8只小鼠。 |
Kinase Experiment | CDK测定在96孔滤板中进行。所有CDK-细胞周期蛋白激酶复合物通过杆状病毒感染在昆虫细胞中表达并纯化。用于测定的底物是与GST融合的pRb的片段(氨基酸792-928)(GST·RB-Cterm)。每孔中的总体积为0.1mL,终浓度为20mM Tris-HCl,pH 7.4,50mM NaCl,1mM二硫苏糖醇,10mM MgCl2,25μMATP(对于CDK4-细胞周期蛋白D1,CDK6-细胞周期蛋白D2,和CDK6-细胞周期蛋白D3)或12μMATP(对于CDK2-细胞周期蛋白E,CDK2-细胞周期蛋白A和CDC2-细胞周期蛋白B)含有0.25μCi的[γ-32P] ATP,20ng酶,1μgGST·RB -Cterm和Palbociclib(0.001-0.1μM)。将除[γ-32P] ATP之外的所有组分加入孔中,并将板置于平板混合器上2分钟。通过加入[γ-32P] ATP开始反应,并将板在25℃温育15分钟。通过加入0.1mL 20%三氯乙酸终止反应,并将板在4℃下保持至少1小时以使底物沉淀。然后用0.2mL 10%三氯乙酸将孔洗涤5次,并用β平板计数器测定放射性掺入。 |
