Median overall survival of mice (n = 5 mice in vehicle and PYR-41; n = 4 mice in NSC group) inoculated with IOWA-1T xenografts were increased to 43 ± 0.5 and 39 ± 2 days with PYR-41 (PYR) and NSC-207895 (NSC), respectively, compared with a vehicle-treated control group 33 ± 1 days (*p < 0.05).

Biological Activity

Description

NSC 207895 suppresses MDMX with IC50 of 2.5 μM, leading to enhanced p53 stabilization/activation and DNA damage, and also regulates MDM2, an E3 ligase.

Targets

p53 ^[1]	MDMX ^[1]
	2.5 μM

In vitro

NSC-207895 decreases both the MDMX mRNA and protein in MCF-7 cells. NSC-207895 induces expression of p53 as well as well-characterized p53-target gene, p21 and MDM2, in a dose-dependent manner in MCF-7 cells. NSC-207895 extends the half-life of p53 from 20 to 30 minutes to more than 3 hours as revealed by cycloheximide chase assays in MCF-7 cells. NSC-207895 also activates p53 and induces p21 and MDM2 expression in LNCaP prostate and A549 lung cancer cells. NSC-207895 increases the mRNA levels of proapoptotic genes including PUMA, BAX, and PIG3 in a dose-dependent manner in MCF-7 cells. NSC-207895 results in a significant increase in the numbers of sub-G0/G1 cells as well as G2 arrest. NSC-207895 also results in more than 40% of cells dying via apoptosis and decreases cell viability in A549 and LNCaP cells. ^[1] NSC-207895 inhibits biosynthesis of nucleic acids and proteins in L1210 cells. ^[2] NSC-207895 interacts with DNA repair to activate the DNA damage repair pathway in three species (S. cerevisiae, S. pombe and H. sapiens). ^[3] NSC-207895 acts as cytotoxic agent in the G/R-luc astrocytoma cell line with GI50 of 117 nM. ^[4]

Protocol

Cell Research:

^[1]

- Collapse

Cell lines: MCF-7 cell
Concentrations: 1-10 μM
Incubation Time: 2 days
Method:
MCF-7 cells treated with dimethyl sulfoxide (DMSO), nutlin-3a, or NSC-207895 are permeabilized with cold 70% ethanol overnight, and stained with a solution containing 50 μg/mL propidium iodide and 20 μg/mL RNase A at 37°C for 20 minutes. The cells are then subjected to flow cytometry analysis. The FlowJo software is used to calculate percentages of cells in each cell cycle phase. For terminal deoxynucleotidyl transferase–mediated dUTP nick end labeling (TUNEL) staining, MCF-7 cells treated with the NSC-207895 for 2 days are fixed with 4% paraformadelhyde for 1 hour, and then subjected to dUTP labeling using In Situ Cell Death Detection Kit TMR Red according to the manufacturer's protocol. For quantitation, at least 300 cells are randomly chosen and the numbers of TUNEL-positive cells are counted.

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.
