Description

NSC 405020 is a noncatalytic inhibitor of MT1-MMP, directly interacts with PEX domain of MT1-MMP, affects PEX homodimerization but not catalytic activity of MT1-MMP.

Targets

MT1-MMP ^[1]

In vitro

NSC 405020 is a noncatalytic inhibitor of MT1-MMP, directly interacts with PEX domain of MT1-MMP. NSC 405020 affects PEX homodimerization but not catalytic activity of MT1-MMP. NSC 405020 (100μM) inhibits migration of cells with high level of MT1-MMP, with a reduction of migration efficiency by about 75%. NSC 405020 does not inhibit migration of cells with low level of MT1-MMP and does not inhibit cell adhesion on collagen.^[1]

In vivo

NSC 405020 (0.5 mg/kg, intratumoral injection) significantly represses tumor growth. NSC 405020 causes a fibrotic, ΔPEX-like tumor phenotype and increases the level of COL-I. ^[1]

Protocol

Kinase Assay:^[1]	- Collapse Migration assays: Assays are conducted in wells of a 24-well, 8 μm pore size Transwell plate. A 6.5-mm insert membrane is coated with 0.1 mL COL-I (300 μg/mL in MEGM) and then air dried for 16 hours. The collagen coating is rehydrated for 1 hour in 0.2 mL MEGM. The inner chamber contains MEGM-10% FBS as a chemoattractant. The compounds (10–100 μmol/L) or DMSO (0.1%–1%) are added to both inner and outer chambers. Before plating in the outer chamber, cells (5×10⁴) are coincubated for 20 minutes with the compounds or DMSO in MEGM. Cells are allowed to migrate for 16 to 18 hours. The cells remaining on the top surface of the membrane are removed with a cotton swab. The cells on the bottom surface of the membrane are fixed and stained (0.2% crystal violet). The incorporated dye is extracted with 1% SDS and the A570 is measured.
Cell Research:^[1]	- Collapse Cell lines: 184B5-MT and MCF7-β3/MT Concentrations: ~400 μM Incubation Time: 24 or 30 h Method: Assays are conducted in wells of a 96-well flat bottom, white wall plates. 184B5-MT and MCF7-β3/MT cells (5×10⁴) are grown for 16 hours in MEGM-10% FBS and DMEM-10% FBS, respectively. 184B5-MT cells are replenished with fresh MEGM (0.1 mL per well) and incubated for an additional 24 hours in the presence of the compounds (100 μM) or vehicle (1% DMSO). MCF7-β3/MT cells are replenished with fresh DMEM-10% FBS (0.1 mL per well) and incubated for an additional 6 hours in the presence of the compounds (400 μM) or vehicle (2% DMSO). The viable cells are counted using a luminescent ATP-Lite assay. (Only for Reference)
Animal Research:^[1]	- Collapse Animal Models: BALB/c nu/nu mice injected with MCF7-β3/WT and MCF7-β3/ΔPEX cells Dosages: 0.5 mg/kg, 3 times per week Administration: Intratumoral injection (Only for Reference)

Bio Calculators

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)

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

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 )

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / 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.
