In Vitro

CDK8-IN-9 (compound 22) (0-100 μM, 48 h) can significantly inhibit cell proliferation and target CDK8 to inhibit the activation of the WNT/β-catenin pathway, thereby suppressing β-catenin-mediated transcriptional activity of TCF/ LEF^[1].
CDK8-IN-9 (compound 22) (0.5,1 and 2 μM, 24 h) induces G2/M and S-phase cell cycle arrest, thereby inhibiting cell proliferation rather than inducing apoptosis^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

CDK8-IN-9 (compound 22) (p.o., 20, 40 and 80 mg/kg, daily, 3 weeks) significantly reduces in tumor volume and inhibits weight loss in mice at the concentration of 80 mg/kg in Balb/c mice infected with CT-26 murine colon cancer cells^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
