In VitroNiraparib (MK-4827) tosylate hydrate inhibits PARP activity with EC50=4 nM and EC90=45 nM in a whole cell assay. Niraparib tosylate hydrate inhibits proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC50 in the 10-100 nM range. Niraparib tosylate hydrate displays excellent PARP 1 and 2 inhibition with IC50=3.8 and 2.1 nM, respectively, and in a whole cell assay. Niraparib tosylate hydrate inhibits PARP within 15 minutes of treatment reaching about 85% inhibition in the A549 cells at 1 h and about 55% inhibition at 1 h for the H1299 cells.

In VivoNiraparib (MK-4827) tosylate hydrate is well tolerated and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer. Niraparib (MK-4827) tosylate hydrate is well tolerated in vivo and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer.Niraparib (MK-4827) tosylate hydrate 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%. Niraparib (MK-4827) tosylate hydrate 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. Animal Model:Female nude mice (Ncr Nu/Nu) with solitary tumor xenografts Dosage:25 mg/kg or 50 mg/kg Administration:Gavage, 25 mg/kg twice a day with 6 h between doses or 50 mg/kg once daily for 21 consecutive days Result:Enhanced radiation response.

Obtustatin
Highly potent integrin α1β1 inhibitor (IC50 = 0.8 nM for α1β1 binding to type IV collagen). Selective for α1β1 over α2β1, αIIbβ3, αvβ3, α4β1, α5β6, α9β1 and α4β7. Inhibits FGF2-stimulated angiogenesis in the chicken chorioallantoic model. Displays antitumor efficacy in a synergistic mouse model of Lewis lung carcinoma; blocks human melanoma growth in nude mice.
