产品描述:一种口服有产的CDK(细胞周期蛋白依赖性激酶)抑制剂,作用于CDK4和CDK6,IC50分别为11nM和16nM。 Palbociclib is an orally available cyclin-dependent kinase (CDK) inhibitor with potential antineoplastic activity. Palbociclib selectively inhibits cyclin-dependent kinase 4 (CDK4) and 6 (CDK6), thereby inhibiting retinoblastoma (Rb) protein phosphorylation early in the G1 phase leading to cell cycle arrest. This suppresses DNA replication and decreases tumor cell proliferation. CDK4 and 6 are serine/threonine kinases that are upregulated in many tumor cell types and play a key role in the regulation of cell cycle progression. Palbociclib, was approved on February 3, 2015 as a treatment (in combination with letrozole) for patients with estrogen receptor-positive advanced breast cancer。
