Werkingsmechanisme (Mechanism of Action)

Targets/IC₅₀/Ki	PARP2 (Cell-free assay) 2.1 nM PARP1 (Cell-free assay) 3.8 nM
In vitro	In een hele cel assay remde Niraparib (MK-4827) de PARP-activiteit met EC50 = 4 nM en remde de proliferatie van kankercellen met gemuteerd BRCA-1 en BRCA-2 met CC50 in het bereik van 10-100 nM. Het bleek een krachtige en selectieve PARP-1 en PARP-2 remmer te zijn met respectievelijk IC50=3,8 en 2,1 nM. Bovendien vertoonde deze verbinding ten minste een 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 vanwege silencing door RNA-interferentie, is het in staat om de proliferatie van kankercellijnen te remmen die natuurlijke BRCA-1 of BRCA-2 mutaties dragen. In MDA-MB-436 humane borstklieradenocarcinoomcellen met BRCA-1 mutaties, vertoonde het CC50 = 18 nM, terwijl het in CAPAN-1 humane pancreasadenocarcinoomcellen, die BRCA-2 mutant zijn, CC50 = 90 nM vertoonde. In tegenstelling hiermee zijn normale humane prostaat- en mamma-epitheelcellen resistent tegen MK-4827, vertonen antiproliferatieve effecten in het micromolaire bereik, waardoor de zeer hoge selectieve cytotoxiciteit van deze PARP-remmers in BRCA-1 en -2 mutante kankercellen vergeleken met omliggend weefsel wordt aangetoond.
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 humane tumor xenografts, zowel p53 wild type als p53 mutant. Het werd in vivo goed verdragen en toonde werkzaamheid als een enkelvoudig middel in een xenograftmodel van BRCA-1 deficiënte kanker.
