Homogeneous suspension

CMC-NA

≥5mg/ml

Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	Iniparib (BSI-201, NSC-746045, IND-71677) は、トリプルネガティブ乳がん (TNBC) において有効性が実証されているPARP1阻害剤です。第3相。
in vitro	Iniparib (BSI-201) is described as a prodrug of 4-iodo-3-nitrosobenzamide, an agent that covalently inhibits PARP1 by binding to its first zinc finger under cell-free conditions. Treatment of 120 μM of this compound plus buthionine sulfoximine (BSO) induces a 95% cell death among 855-2 cells, and displays a similar effect in other human cancer cells. It inhibits the growth of E-ras 20 cells, the effect of which can be augmented 4-fold when BOS is added. Recently it shows no ability to inhibit PARP enzymatic or cellular activity, but can non-selectively modify cysteine-containing proteins in tumor cells, suggesting the mechanism of action is likely not via inhibition of PARP activity. At 100 μM, it inhibits ionizing radiation-induced single-strand breaks (SSBs) repair in human lymphoid cell lines based on large endogenous Epstein–Barr virus (EBV) circular episomes assay, resulting in 55% repair by 2 hours, which can be reversed surprisingly by knockdown of PARP1, indicating that the mechanism of inhibition does not involve trapping PARP at SSBs. This compound is not able to selectively kill homologous recombination (HR)-deficient cells between BRCA2-deficient PEO1 and BRCA2-revertant PEO4, or ATM-deficient GM16666 and ATM-restored GM16667 fibroblasts. It is cytotoxic to a variety of cell lines at concentrations above 40 μM reflecting a mechanism independent of PARP.
