生物活性:
Rucaparib (AG014699) acetate is an orally active, potent inhibitor of PARP proteins (PARP-1, PARP-2 and PARP-3) with a Ki of 1.4 nM for PARP1. Rucaparib acetate is a modest hexose-6-phosphate dehydrogenase (H6PD) inhibitor. Rucaparib acetate has the potential for castration-resistant prostate cancer (CRPC) research.

体内研究:
Rucaparib (AG014699) acetate and AG14584 significantly increase Temozolomide toxicity. Rucaparib (1 mg/kg) acetate significantly increases Temozolomide-induced body weight loss. Rucaparib (0.1 mg/kg) acetate esults in a 50% increase in the temozolomide-induced tumor growth delay. Rucaparib (10?mg/kg for i.p. or 50, 150 mg/kg for p.o.; daily for 5 days per week for 6 weeks) acetate significantly inhibits the growth of the tumor, and there is one complete tumor regression and two persistent partial regressions.Rucaparib (150?mg/kg; p.o.; once per week for 6 weeks or three times per week for 6 weeks) acetate has greatest antitumor effect with three complete regressions. Rucaparib acetate enhances the antitumor activity of temozolomide and indicates complete and sustained tumor regression in NB1691 and SHSY5Y xenografts.

体外研究:
Rucaparib (AG014699) acetate is a possible N-demethylation metabolite of AG14644. Rucaparib (0.1, 1, 10, 100 μM; 24 hours) acetate is cytotoxic and has the LC50 being 5?μM in Capan-1 (BRCA2 mutant) cells and only 100?nM in MX-1 (BRCA1 mutant) cells. The radio-sensitization by Rucaparib acetate is due to downstream inhibition of activation of NF-κB, and is independent of SSB repair inhibition. Rucaparib acetate can target NF-κB activated by DNA damage and overcome toxicity observed with classical NF-κB inhibitors without compromising other vital inflammatory functions. Rucaparib acetate inhibits PARP-1 activity by 97.1% at a concentration of 1 μM in permeabilised D283Med cells.
