产品介绍
Entrectinib (NMS-E628) 是一种有效的、可口服的、具有 CNS 活性的泛 Trk、ROS1 和 ALK 抑制剂。 Entrectinib 抑制 TrkA、TrkB、TrkC、ROS1 和 ALK,IC50 值分别为 1、3、5、12 和 7 nM。抗肿瘤活性。

Cell lines

SH-SY5Y cells stably transfected with TrkB

Preparation method

The solubility of this compound in DMSO is >28.1 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months.

Reacting condition

1 ~ 200 nM; 1 hr

Applications

In SY5Y-TrkB cells, Entrectinib inhibited Trk phosphorylation in a dose-dependent manner. At the dose as low as 1 nM, Entrectinib significantly inhibited Trk phosphorylation, and complete inhibition was achieved at the concentration of 10 nM or higher concentrations. Meanwhile, Entrectinib showed no effect on the Trk-null parental SH-SY5Y cells.

Animal models

Nu/nu mice bearing SY5Y-TrkB cells

Dosage form

60 mg/kg; p.o.; b.i.d., 7 days/week

Applications

Entrectinib significantly inhibited tumor growth and prolonged EFS. Analyses of the tumors collected at different time points after treatment (1, 4 and 6 hrs, respectively) indicated inhibition of TrkB phosphorylation in mice treated with Entrectinib. Moreover, phosphorylation of p-PLCγ, p-Akt and p-Erk was also inhibited in Entrectinib-treated mice. In addition, Western blot results also indicated that phosphoprotein expression was significantly suppressed in xenografts upon Entrectinib treatment.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

The receptor tyrosine kinases (RTKs) play a critical role, controlling cell proliferation, survival, and differentiation of normal cells. The anaplastic lymphoma kinase (ALK), a transmembrane RTK, originally identified in the nucleophosmin (NPM)–ALK chimera of anaplastic large cell lymphoma, has emerged as a novel tumorigenic player in several human cancers. Entrectinib is an orally available small-molecule inhibitor of ALK kinase activity.

In vitro: Entrectinib potently and selectively inhibits the in vitro growth of ALK-driven tumors, with confirmed mechanism of action [1].

In vivo: Since Entrectinib is able to pass the blood-brain barrier, the compound was also tested for efficacy in an xenograft model with ALK positive NSCLC tumors. MRI imaging demonstrated that Entrectinib was able to effectively and control the growth of these intracranial tumors dose-dependently, leading to increased survival [1].

Clinical trial: Entrectinib is an orally available small-molecule inhibitor of ALK kinase activity that is being evaluated in phase I/II clinical study to treat solid cancer
