(S)-2-(4-(piperidin-3-yl)phenyl)-2H-indazole-7-carboxaMide Chemical Properties,Uses,Production

Uses

Niraparib hydrochloride (MK-4827 hydrochloride) is a highly potent and orally bioavailable PARP1 and PARP2 inhibitor with IC50s of 3.8 and 2.1 nM, respectively. Niraparib hydrochloride leads to inhibition of repair of DNA damage, activates apoptosis and shows anti-tumor activity[1][2][3].

in vivo

Niraparib is well tolerated and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer. Niraparib is well tolerated in vivo and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer. Niraparib is characterized by acceptable pharmacokinetics in rats with plasma clearance of 28 (mL/min)/kg, very high volume of distribution (Vdss=6.9 L/kg), long terminal half-life (t1/2=3.4 h), and excellent bioavailability, F = 65%[1]. Niraparib enhances radiation response of p53 mutant Calu-6 tumor in both cases, with the single daily dose of 50 mg/kg being more effective than 25 mg/kg given twice daily[3].

IC 50

PARP-2: 2.1 nM (IC50); PARP-1: 3.8 nM (IC50); V-PARP: 330 nM (IC50); TANK-1: 570 nM (IC50); PARP-3: 1300 nM (IC50)
