Ribociclib/瑞博西尼生物活性

靶点	CDK4 CDK4, IC50:10 nM CDK6 CDK6, IC50:39 nM
描述	CDK4/6, forming a complex with its partner Cyclin D1/2/3, can mediate the phosphorylation of Rb in G1 cell cycle, as well as stimulating the synthesis cyclin E and D-type cyclins controlled by extracellular mitogens^[1]. LEE011 (Ribociclib) is an orally bioavailable dual CDK4/6 inhibitor with IC50 values of 10 nM and 40 nM, respectively^[2]. Treatment of LEE011 (0.25 - 10 μM) can cause decrease in pRB-S780 accompany growth suppression in BE2C, EBC1, IMR5 and SKNAS neuroblastoma cell lines by a dose-dependent manner. 100 - 250nM of LEE011 can cause accumulation of G0/G1 phase of the cell cycle and cellular senescence with decreased FOXM1 in BE2C and IMR5 cells. Treatment of once daily for 21 days with 200mg/kg LEE011 can suppress neuroblastoma growth in mice with subcutaneously implanted BE2C or 1643 xenografts^[3]. There are currently 16 active clinical trials with LEE011 as single agent or in combination with other drugs of treatment for melanoma, breast cancer, neuroblastoma, malignant rhabdoid and lymphomas^[4].
作用机制	LEE011 can inhibit CDK4/6 in an ATP-competitive manner through its pyrrolo[2,3d]pyrimidine core^[5].

溶解方案

细胞实验：

DMSO: 5 mg/mL(11.51 mM)，配合低频超声助溶，注意：DMSO长时间开封后，会吸水并导致溶解能力下降，请避免使用长期开封的DMSO

动物实验：请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议现用现配，当天使用；以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶
