Alsterpaullone (9-Nitropaullone) is a potent CDK inhibitor, with IC₅₀s of 35 nM, 15 nM, 200 nM and 40 nM for CDK1/cyclin B, CDK2/cyclin A, CDK2/cyclin E and CDK5/p35, respectively. Alsterpaullone also competes with ATP for binding to GSK-3alpha/GSK-3beta with IC₅₀s of both 4 nM. Alsterpaullone has antitumor activity, and possesses potential for the study in neurodegenerative and proliferative disorders. Alsterpaullone induces apoptosis in leukemia cell line.

In Vitro

Alsterpaullone (0.3, 1, 3 μM; 8 hours) induces apoptosis in leukemia cell line^[2].
Alsterpaullone (5, 10, 15, 20, 25, 30 μM; 48 and 72 hours) inhibits the growth of HeLa cells in dose-and time-dependent manner. Treatment with Alsterpaullone causes a time-dependent inhibition of cell growth too^[3].
Alsterpaullone (20 μM) induces cell death depending on caspase activity^[3].

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

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.
