BSI-401 is a novel PARP-1 inhibitor with both oral bioavailability and strong antitumor potency. The IC50 of BSI-401 for all of the five pancreatic cancer cell lines was <15 μM. BSI-401 inhibits the growth of pancreatic cancer cells in vitro significantly. BSI-401 inhibits low-anchorage tumor cell colony formation. BSI-401 combined with oxaliplatin had potent synergistic antitumor activity (46 versus 132 days, P = 0.0063), and significantly (P = 0.0148) prevented acute oxaliplatin-induced neurotoxicity.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
Oral poly(ADP-ribose) polymerase-1 inhibitor BSI-401 has antitumor activity and synergizes with oxaliplatin against pancreatic cancer, preventing acute neurotoxicity.
