Home Cell Cycle CDK inhibitor Simurosertib For research use only.

Simurosertib

Synonyms: TAK-931

Simurosertib (TAK-931), an oral cell division cycle 7 (CDC7)-selective inhibitor with an IC50<0.3 nM, induces S phase delay and replication stress and causes mitotic aberrations through centrosome dysregulation and chromosome missegregation, resulting in irreversible antiproliferative effects in cancer cells.

Biological Activity

Description Simurosertib (TAK-931), an oral cell division cycle 7 (CDC7)-selective inhibitor with an IC50<0.3 nM, induces S phase delay and replication stress and causes mitotic aberrations through centrosome dysregulation and chromosome missegregation, resulting in irreversible antiproliferative effects in cancer cells.
Targets
Cdc7 [1]
(in CDC7 enzyme assay)
0.3 nM
In vitro
In vitro

Simurosertib (TAK-931) induces S phase delay and Replication stress (RS). Simurosertib-induced RS causes mitotic aberrations through centrosome dysregulation and chromosome missegregation, resulting in irreversible antiproliferative effects in cancer cells.<sup><a class="sref" href="#s_ref">[1]</a></sup>
Cell Research Cell lines COLO205, SW948
Concentrations 0.01-3 mM
Incubation Time 72 h
Method

Simurosertib is added 24 hours after cell seeding. After a 72-hour incubation with Simurosertib, cells are fixed and stained with nuclear dye and fluorescently labeled pHH3 to allow visualization of nuclei and mitotic cells.
In Vivo
In vivo

Simurosertib (TAK-931) has marked, dose-dependent antitumor activity, without severe body weight loss in the pancreatic cancer cell (COLO205 and SW948) xenograft models.<sup><a class="sref" href="#s_ref">[1]</a></sup>

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.
