in vivo suppression of PAR formation by the PARP inhibitor AZD2281 upon induction of DNA damage Primary human lung fibroblast cells (MRC-5) were pre-treated with the indicated concentration of the PARP inhibitor AZD2281 for two hours. Oxidative DNA damage was induced by 500 µM H2O2 for 10 min and cellular PARP activity was measured by immuno-staining of poly(ADP)-ribose (PAR) (right panels). The in vivo effect of PARP inhibition was compared to cells without DNA damage induction and inhibitor (control) and H2O2-treated cells without inhibitor. Average nuclear PAR staining intensities of more than 50 cells were statistically analysed by Kruskal-Wallis and the post-hoc Dunn’s Multiple Comparison tests (left panel). Asterisks indicate highly significant (p<1%) differences to H2O2-treated cells without PARP inhibitor. Thick horizontal bars mark medians and error bars the interquartile range.

| In vitro |
Olaparib would act against BRCA1 or BRCA2 mutations. Olaparib is not sensitive to tankyrase-1 (IC50 >1 μM). Olaparib could ablate the PARP-1 activity at concentrations of 30-100 nM in SW620 cells. Olaparib is hypersensitive to BRCA1-deficient cell lines (MDA-MB-463 and HCC1937), compared with BRCA1- and BRCA2-proficient cell lines (Hs578T, MDA-MB-231, and T47D). [1] Olaparib is strongly sensitive to KB2P cells due to suppression of base excision repair by PARP inhibition, which may result in the conversion of single-strand breaks to double-strand breaks during DNA replication, thus activating BRCA2-dependent recombination pathways.

| In vivo | Combining with temozolomide, Olaparib (10 mg/kg, p.o.) significantly suppresses tumor growth in SW620 xenografts. [1] Olaparib shows great response to Brca1-/-;p53-/- mammary tumors (50 mg/kg i.p. per day), while no responses to HR-deficient Ecad-/-;p53-/- mammary tumors. Olaparib even does not show dose-limiting toxicity in tumor-bearing mice. [3] Olaparib has been used to treat with BRCA mutated tumors, such as ovarian, breast and prostate cancers. Moreover, Olaparib shows selectively inhibition to ATM (Ataxia Telangiectasia Mutated)-deficient tumor cells, which indicates to be a potential agent for treating ATM mutant lymphoid tumors. [4] |
Protocol
| Kinase Assay: |
+ Expand
FlashPlate assay (96-well screening assay): To columns 1 through 10, 1 μL of Olaparib (in DMSO) is added, and 1 μL DMSO only is added to the positive (POS) and negative (NEG) control wells (columns 11 and 12, respectively) of a pretreated FlashPlate. PARP-1 is diluted 1:40 in buffer (buffer B: 10% glycerol (v/v), 25 mM HEPES, 12.5 mM MgCl2,50 mM KCl, 1 mM DTT, 0.01% NP-40 (v/v), pH 7.6) and 40 μL added to all 96 wells (final PARP-1 concentration in the assay is ~1 ng/μL). The plate is sealed and shaken at RT for 15 min. Following this, 10 μL of positive reaction mix (0.2 ng/μL of double-stranded oligonucleotide [M3/M4] DNA per well, 5 μM of NAD+ final assay concentration, and 0.075 μCi 3H-NAD+ per well) is added to the appropriate wells (columns 1-11). The negative reaction mix, lacking the DNA oligonucleotide, is added to column 12 (with the mean negative control value used as the background). The plate is resealed and shaken for a further 60 min at RT to allow the reaction to continue. Then, 50 μL of ice-cold acetic acid (30%) is added to each well to stop the reaction, and the plate is sealed and shaken for a further 60 min at RT. Tritiated signal bound to the FlashPlate is then determined in counts per minute (CPM) using the TopCount plate reader. |

For the formulation for in vivo, the compound dissolving in 15% Captisol (former solubility) is a suspension, and it is fine for oral gavage. And now, dissolving in 4% DMSO+30% PEG 300+ddH2O is a clear solution, and is for injection.
-
Question 2:
How long can the chemical compound be stable in DMEM at 4 ℃?
-
Answer:
