Alsterpaullone (Synonyms: 9-Nitropaullone,NSC 705701)

Catalog No.GC15841

L'alsterpaullone (9-Nitropaullone) est un puissant inhibiteur de CDK, avec des IC50 de 35 nM, 15 nM, 200 nM et 40 nM pour CDK1/cycline B, CDK2/cycline A, CDK2/cycline E et CDK5/p35, respectivement. L'alsterpaullone entre également en compétition avec l'ATP pour la liaison À GSK-3alpha/GSK-3beta avec des IC50 de 4 nM. L'alsterpaullone a une activité antitumorale et possède un potentiel pour l'étude des troubles neurodégénératifs et prolifératifs. Alsterpaullone induit l'apoptose dans la lignée cellulaire de la leucémie.

Description of Alsterpaullone

Alsterpaullone is a small molecule cyclin-dependent kinase (CDK) inhibitor [1,2].

Cyclin-dependent kinases (CDKs) are protein kinases that play important roles in the control of cell division and modulate transcription in response to several extra- and intracellular cues. Deregulation of CDKs is a hallmark of several diseases, including cancer, and drug-targeted inhibition of specific members has generated very encouraging results in clinical trials [3].

Alsterpaullone (Alp) induced apoptosis and promoted loss in clonogenicity in the Jurkat cell line. Alp activated both caspase-8 and -9, leading to cleavage of caspase-3 and poly (ADP-ribose) polymerase (PARP). Alp disrupted the activation of caspase-9 followed mitochondrial perturbation. Alp activated caspase-9 via mitochondrial perturbation [1]. Alsterpaullone regulated the cell cycle progression. Alsterpaullone inhibited HeLa cells in a time-dependent (0–72 h) and dose-dependent (0–30 μM) manner. Alsterpaullone arrested HeLa cells in G2/M prior to undergoing apoptosis via a mechanism that is involved in the regulation of various antiapoptotic genes, DNA-repair, transcription, and cell cycle progression. Alsterpaullone effectively prevented HeLa cells from entering S-phase [2].

Calculation results:

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.
3. All of the above co-solvents are available for purchase on the GlpBio website.
