Biological Activity

Description

Rucaparib is an inhibitor of PARP with Ki of 1.4 nM for PARP1 in a cell-free assay, also showing binding affinity to eight other PARP domains.

Targets

PARP1 ^[1]
(Cell-free assay)

1.4 nM(Ki)

In vitro

Rucaparib, the PARP inhibitor, exhibits a synergetic antiproliferative effect by enhancing apoptosis and DNA damage and reducing HR repair in BRCA-proficient GBM when combined with PI3K inhibitor BKM120.^[2]

In vivo

Rucaparib combined with BKM120 enhances the antitumor efficacy in a nude mouse U87MG subcutaneous xenograft model and nude mouse U87MG orthotopic xenograft model.^[2]

Protocol (from reference)

Cell Assay:^{^[2]}	Cell lines GBM U251 and U87MG cells Concentrations 0.1, 1, 10, 100 μM Incubation Time 4 days Method Cell proliferation is measured by MTT assay. The cells are seeded at a density of 5×10³ cells/ml in a volume of 200 μl/well in 96-well plates. The next day, cells are treated with DMSO or a series of concentrations of BKM120 or rucaparib. Four days later, 20 μl of MTT (5 mg/ml) is added to each well. After further incubation for 4 h at 37 ℃, the absorbance at 490 nm is measured. Data obtained from the growth inhibitory experiments are analyzed by CalcuSyn software to determine the drug combination effect. Combination indexes (CI) are then calculated.
