Description	Iniparib (BSI-201) is an irreversible inhibitor of PARP1, used in the research of triple negative breast cancer.
Related Catalog	Signaling Pathways >> Cell Cycle/DNA Damage >> PARP Signaling Pathways >> Epigenetics >> PARP Research Areas >> Cancer
Target	PARP1
In Vitro	Iniparib nonselectively modifies cysteine-containing proteins in tumor cells[1]. Iniparib (100 μM) weakly inhibits SSB repair, and the inhibition can be reversed by knockdown of PARP1[2]. Iniparib in combination with cisplatin is cytotoxic to Myc/MDA-231 with EMT changes[3].
Cell Assay	For nine day cell proliferation assay, MDA-MB-436 and MDA-MB-231 cells are plated at 2000 and 500 cells/well respectively in a 96-well plate and treated with veliparib, cmpd-A, cmpd-C, Iniparib or Iniparib-met at 0, 0.0001, 0.01,0.1, 1 or 10 μM for nine days. For five day cell proliferation assay, MDAMB-231 and MDA-MB-436 cells are plated at 1000 and 4000 cells/well respectively in a 96-well plate and treated with Iniparib or Iniparib-met at 0. 0.1, 0.3, 1, 3 or 10 μM in the presence of 0, 1.8, 3.75, or 7.5 µM BSO for 5 days. DLD1+/+ and DLD1-/- cells are plated at 1000 cells/well in a 96-well plate and treated with TMZ at 0, 0.003, 0.01, 0.03, 0.1, 0.3 or 1 mM in the presence of 0, 0.005, 0.05, 0.5, or 5 µM veliparib, or Iniparib for five days. After treatment, cell titer glow is carried out[1].
