...ave a secondary mutation on their BRCA2 gene, their cancer likely would be resistant not only to platinum-based compounds but also other drugs such as parp inhibitors. Testing whether relapsed tumors have a secondary mutation of BRCA2 may be important to predict clinical outcome, Taniguchi said. The rese...Americans Optimistic About the War on Cancer
...cientists from independent academic institutions and Abbott will present data on several of Abbott's investigational anti-cancer compounds including a parp inhibitor (ABT-888) that seeks to enhance the effectiveness of common cancer therapies, a multi-targeted kinase inhibitor (ABT-869) being investigated...Astrazeneca's Investigational Cancer Therapies Revealed at ASCO
...s been studied in a range of tumor types in Phase I studies. The study presented today at ASCO showed that treatment with AZD2281 led to inhibition of parp functional activity in both surrogate and tumor tissue, and reported that strong signals were detected in hereditary ovarian cancer.

Detection of early apoptotic events has become quite relevant since many studies have demonstrated that abnormalities in cell death regulation cause a variety of diseases and pathological conditions accompanied either b...A DELFIA Assay for Inhibition of PARP
The DELFIA time-resolved fluorescence assay for inhibition of poly(ADP-ribose) polymerase (PARP) is a 96-well microplate assay that measures the inhibition of PARP-activated incorporation of biotinylated nicotinamide adenine diphsophate (NAD). The incorporation is detected using Europiuml...Sanofi-aventis Announces Second Quarter 2009 Results

Description:...M LIGHT. PACKAGED UNDER INERT GAS. A brain-permeable and water soluble pyrimidinone compound that acts as a potent and NAD + -competitive inhibitor of parp (IC 50 = 200 nM and 240 nM for rhPARP1 and rmPARP2, respectively) with little activity against the dehydrogenase activity of GAPDH, ADH, LDH, or the ...PARP Cleavage Detection Kit from Calbiochem
