  • WT mouse primary macrophages were untreated as control (lane 1) or treated with 0.1μg/ml E. coli LPS (lane 5-8), 10μM E-64 (lane 2 and 6), 250μM PMSF (lane 3 and 7), or 20μM MNS (lane 4 and 8). The cells were continuously cultured for 16 hrs. Extracts from whole cells or nuclei were separately purified and subjected to WB analysis with antibody against pERK2, LITAF, or actin/tubulin as control.

Biological Activity

Description MNS is a tyrosine kinase inhibitor, inhibits Syk, Src, p97 with IC50 of 2.5 μM, 29.3 μM and 1.7 μM, respectively.
Features The nitro group of MNS (3,4-Methylenedioxy-β-nitrostyrene) is essential for its antiplatelet effect.

In vitro

MNS (3,4-methyl-enedioxy-β-nitrostyrene) completely inhibits 2 μM U46619-(a thromboxane A2 mimic), 5 μM ADP-, 100 μM arachidonic acid-(AA), 10 μg/ml collagen-, and 0.1 U/ml thrombin-induced platelet aggregation in a concentration-dependent manner with IC50 of 2.1 μM, 4.1 μM, 5.8 μM, 7.0 μM, and 12.7 μM, respectively. MNS inhibits platelet aggregation caused by either the calcium ionophore A23187 (1 μM) or the protein kinase C (PKC) activator PDBu (200 nM) with IC50 of 25.9 μM and 4.8 μM, respectively. MNS (20 μM) decreases dthrombin-induced P-selectin expression on platelets to levels comparable to those observed in PGE1-treated platelets. MNS (20 μM) markedly inhibits thrombin-but not PDBu-induced MARCKS phosphorylation in platelets. MNS (20 μM) markedly inhibits protein tyrosine phosphorylation at either 0.5 min or 3 min after thrombin or collagen stimulation in platelets. [1] MNS stimulates UbG76V-GFP and ODD-Luc degradation with IC50 of 1.6 μM and 5.9 μM, respectively. MNS inhibits MG132-induced accumulation of the reporter with IC50 of 2.1 μM. [2] MNS inhibits Gram-positive (Staphylococcus aureus and Enterococcus faecalis) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria with minimum inhibitory concentrations (MICs) of 128 mg/L. [3] MNS is much more potent than genistein in inhibiting platelet aggregation and protein tyrosine phosphorylation. MNS (3,4-Methylenedioxy-β-nitrostyrene) is equally potent as inhibitors of platelet aggregation as 3,4-dimethoxy-β-nitrostyrene. MNS (20 μM) concentration-dependently prevents ATP release from platelets stimulated by thrombin or collagen. MNS (20 μM) inhibits thrombin-induced PAC-1 binding to human platelets. [4]

Bio Calculators

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
    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 )

  • C1

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

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.
