Biological Activity

Description IPA-3 is a selective non-ATP competitive Pak1 inhibitor with IC50 of 2.5 μM in a cell-free assay, no inhibition to group II PAKs (PAKs 4-6).
Features IPA-3 binds covalently to the Pak1 regulatory domain and prevents binding to the upstream activator Cdc42.
Targets
PAK1 [1]
(Cell-free assay)
2.5 μM
In vitro

IPA-3 is a non ATP-competitive, allosteric inhibitor of p21-activated kinase 1 (Pak1). PIR3.5 is the control compound of IPA-3. IPA-3 prevents Cdc42-stimulated Pak1 autophosphorylation on Thr423. IPA-3 also prevents sphingosine-dependent Pak1 autophosphorylation. IPA-3 does not target exposed cysteine residues on Pak1. The disulfide bond of IPA-3 is critical for inhibition of Pak1 and in vitro reduction by the reducing agent dithiothreitol (DTT) abolishes Pak1 inhibition by IPA-3. IPA-3 inhibits activation of Pak1 by diverse activators, but does not inhibit preactivated Pak1. IPA-3 inhibits PDGF-stimulated Pak activation in mouse embryonic fibroblasts. [1] IPA-3 inhibits Pak1 activation in part by binding covalently to the regulatory domain of Pak1. IPA-3 binds Pak1 covalently in a time- and temperature-dependent manner. IPA-3 prevents binding of the Pak1 activator Cdc42. IPA-3 binds directly to the Pak1 autoregulatory domain. IPA-3 reversibly inhibits PMA-induced membrane ruffling in cells. [2]

PubMed: 24844382     


Cells were pretreated with 50 µM IPA-3 for 30 min and then incubated with Alexa555-labeled SubAB for 1 h at 37 °Cells were imaged by confocal microscopy for colocalization of SubAB (red) with BiP (green) as described in Materials and Methods. Bars represent 20 µm. Experiments were repeated two times with similar results.

NF-κB; 

PubMed: 23894351     


Effect of IPA-3 on subcellular localization of NF-κB was evaluated by immunofluorescence staining. After overnight serum starvation, H2M (left panel) and MIHA (right panel) cells were treated with either DMSO or IPA-3 (20 µM, 15 minutes) followed by an addition of TNF-α (20 ng/ml, 15 minutes). NF-κB was detected with a specific antibody (Green) and nucleus was stained with DAPI (Blue).

Paxillin; 

PubMed: 23894351     


Paxillin protein expression was detected by immunofluorescence analysis under IPA-3 treatment. H2M and H2P (upper panel) cells were serum-starved overnight and treated with either DMSO control or IPA-3 (20 µM) for 15 minutes, followed by FBS replenishment for 10 minutes. Immunofluoresence signals of phalloidin (Red), paxillin (Green) and DAPI (Blue) represent stress fiber, focal adhesion and nucleus, respectively (magnification 40X). The number of focal adhesion (paxillin) were counted in H2M (lower, left panel) and H2P (lower, right panel), and represented in the bar chart. Error bars, mean ± SD of triplicate samples. *P<0.01 (t-test) compared with DMSO control.

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Concentration
    Volume
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Frequently Asked Questions

  • Question 1:

    If this product is cell membrane permeable and would it be suitable for PAK1 inhibition on a pancreatic beta cell line?

  • Answer:

    Based on the reference, I think IPA-3 is able to penetrate the cell membrane, it's likely to inhibit PAK1 on a pancreatic beta cell line although there is no reference confirming it: Figure 3: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3963893/; http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4353635/
