Biological Activity

Description ASP3026 is a novel and selective inhibitor for ALK with IC50 of 3.5 nM. Phase 1.
Features ALK-selective inhibitor that has been tested in Phase I clinical trials for treatment of solid tumors and B-cell lymphoma.
ALK [1]
3.5 nM
In vitro

ASP3026 shows more selective ALK inhibition in a Tyr-kinase panel than PF02341066. ASP3026 inhibits the growth of NCI-H2228, a human NSCLC tumor cell line endogenously expressing EML4-ALK variant 3, with an IC50 value of 64.8 nM. [1]

In vivo ASP3026, administered to mice bearing subcutaneous NCI-H2228 tumor xenografts as twice daily oral dosing for 14 days, induces dose dependent anti-tumor effects starting at 1 mg/kg with strong regression at 10, 30 and 100 mg/kg. [1]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
