Niraparib (MK-4827) Chemical Structure

CAS No. 1038915-60-4

Niraparib (MK-4827) is a selective inhibitor of PARP1/2 with IC50 of 3.8 nM/2.1 nM, with great activity in cancer cells with mutant BRCA-1 and BRCA-2. It is >330-fold selective against PARP3, V-PARP and Tank1. Niraparib can form PARP–DNA complexes resulting in DNA damage, apoptosis, and cell death. Phase 3.

Description Niraparib (MK-4827) is a selective inhibitor of PARP1/2 with IC50 of 3.8 nM/2.1 nM, with great activity in cancer cells with mutant BRCA-1 and BRCA-2. It is >330-fold selective against PARP3, V-PARP and Tank1. Niraparib can form PARP–DNA complexes resulting in DNA damage, apoptosis, and cell death. Phase 3.

In a whole cell assay, MK-4827 inhibited PARP activity with EC50 = 4 nM and inhibited proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC50 in the 10-100 nM range. It was demonstrated to be a potent and selective PARP-1 and PARP-2 inhibitor with IC50=3.8 and 2.1 nM, respectively. Furthermore, it displayed at least a 100-fold selectivity over PARP-3, V-PARP, and tankyrase-1, with IC50 = 1300, 330, and 570 nM, respectively. As well as inhibiting the growth of HeLa cell lacking BRCA-1 because of silencing by RNA interference, MK-4827 is able to inhibit the proliferation of cancer cell lines carrying natural BRCA-1 or BRCA-2 mutations. In MDA-MB-436 human mammary gland adenocarcinoma cells carrying BRCA-1 mutations, MK-4827 displayed CC50 = 18 nM, while in CAPAN-1 human pancreatic adenocarcinoma cells, which are BRCA-2 mutant, MK-4827 displayed CC50 = 90 nM. In contrast, normal human prostate and mammary epithelial cells are resistant to MK-4827, displaying antiproliferative effects in the micromolar range, thereby demonstrating the very high selective cytotoxicity from these PARP inhibitors in BRCA-1 and -2 mutant cancer cells compared to surrounding tissue[2].

In vivo MK-4827, a novel, orally bioavailable, PARP-1 and PARP-2 inhibitor, strongly enhanced the effect of radiation on a variety of human tumor xenografts, both p53 wild type and p53 mutant[1]. It was well tolerated in vivo and demonstrated efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer[2].

Protocol

Cell Research:[2]
- Collapse
  • Cell lines: HeLa BRCA1-silenced cells
  • Concentrations: serial dilutions
  • Incubation Time: 7 days
  • Method: Proliferation assays were conducted in 96-well black viewplates, and 300 cells/well (250 cell/well for BRCA-1 wt) in culture medium, 190 μL/well (DMEM containing 10% FCS, 0.1 mg/mL penicillin-streptomycin, and 2 mM L-glutamine), were plated and incubated for 4 h at 37℃ under 5% CO2 atmosphere. Inhibitors were then added with serial dilutions, 10 μL/well to obtain the desired final compound concentration in 0.5% DMSO. The cells were then incubated for 7 days at 37℃ in 5% CO2 after which time viability was assessed. Briefly, with CellTiter-Blue solution prediluted 1:10 in medium, 100 μL/well was added and the cells left for 45 min at 37℃ under 5% CO2 and then a further 15 min at room temperature in the dark. The number of living cells was determined by reading the plate at fluorimeter, excitation at 550 nm and emission at 590 nm. Cell growth was expressed as the percentage growth with respect to vehicle treated cells. The concentration required to inhibit cell growth by 50% (CC50) was determined.

*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.
