Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysische methoden zoals vortexen, echografie of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme

Targets/IC₅₀/Ki	PARP2 (Cell-free assay) 2.1 nM PARP1 (Cell-free assay) 3.8 nM
In vitro	In een hele celassay remde Niraparib (MK-4827) de PARP-activiteit met EC50 = 4 nM en remde de proliferatie van kankercellen met mutante BRCA-1 en BRCA-2 met CC50 in het bereik van 10-100 nM. Het bleek een potente en selectieve PARP-1- en PARP-2-remmer te zijn met respectievelijk IC50=3,8 en 2,1 nM. Bovendien vertoonde deze verbinding een ten minste 100-voudige selectiviteit ten opzichte van PARP-3, V-PARP en tankyrase-1, met respectievelijk IC50 = 1300, 330 en 570 nM. Naast het remmen van de groei van HeLa-cellen die BRCA-1 missen als gevolg van silencing door RNA-interferentie, is het in staat de proliferatie van kankercellijnen met natuurlijke BRCA-1- of BRCA-2-mutaties te remmen. In MDA-MB-436 menselijke borstklieradenocarcinoomcellen met BRCA-1-mutaties vertoonde het CC50 = 18 nM, terwijl in CAPAN-1 menselijke pancreasklieradenocarcinoomcellen, die BRCA-2-mutant zijn, het CC50 = 90 nM vertoonde. Daarentegen zijn normale menselijke prostaat- en mamma-epitheelcellen resistent tegen MK-4827, waarbij antiproliferatieve effecten in het micromolaire bereik worden waargenomen, wat de zeer hoge selectieve cytotoxiciteit van deze PARP-remmers in BRCA-1- en -2-mutante kankercellen aantoont in vergelijking met het omringende weefsel.
In vivo	Niraparib (MK-4827), een nieuwe, oraal biologisch beschikbare PARP-1- en PARP-2-remmer, versterkte sterk het effect van straling op een verscheidenheid aan menselijke tumorxenografts, zowel p53 wild type als p53 mutant. Het werd goed verdragen in vivo en toonde werkzaamheid als een enkelvoudig middel in een xenograftmodel van BRCA-1-deficiënte kanker.
