概括

内巴尔博西基利布是一种依赖于环素的激酶4和6 (CDK4/6) 抑制剂,对患有脑脊液 (CSF) 扩散的儿科脑瘤 (PBTs) 显示出有前景. 这种新的输送方法在临床前模型中提高了疗效和存活率.

科学领域:

在瘤学瘤学.
药理学药理学是指药理学的学科.
神经科学是一个神经科学.

背景情况:

循环素依赖性激酶4和6 (CDK4/6) 抑制剂显示出中枢神经系统 (CNS) 瘤的潜力.
挑战包括有限的中枢神经系统透,治疗持续时间和儿科脑瘤 (PBTs) 的全身毒性.

研究的目的:

为了评估CDK4/6抑制剂,特别是palbociclib,对于PBTs.
为了评估肠内 (IT) 输送palbociclib的疗效和安全性.
为了调查leptomeningealPBT模型的计量信息技术交付.

主要方法:

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
