Biological Activity

AZD 2281 (Olaparib, KU-0059436) is a  novel, potent orally active PARP (poly ADP-ribose polymerase) inhibitorwith IC50 of 5 and 1 nM for PARP-1and PARP-2  respectively. AZD 2281 (Olaparib, KU-0059436) acts as an inhibitor of the enzyme Poly ADP ribose polymerase (PARP) and is one of the first PARP inhibitors.It induces cancer specific synthetic lethality in homologous recombination repair defective cells, including BRCA-deficient tumors.

Protocol
Cell Experiment
Cell lines SW620 colorectal cell line
Preparation method Potentiation of MMS Cytotoxicity by 47 Determined by the Use of Sulforhodamine B Cell Growth Assays. SW620 cells were seeded in 96-well plates and were left to attach overnight. Cells were preincubated with vehicle control (DMSO) or with a single concentration of KU-0059436 (1, 3, 10, 30, 100 or 300 nM) for 1 h before the addition of increasing concentrations of MMS. Cells were incubated in the presence of each drug combination for 4 days before cell growth was quantified by the use of an SRB assay.44 Data were calculated from triplicate wells as the mean percentage of cell growth relative to KU-0059436-only wells, and (SE and IC50 were calculated by the use of XL-FIT 4 software. SW620 cells showed <24% growth inhibition (>76% cell growth) when only KU-0059436 was used at concentrations below 300 nM (data not shown).
Concentrations 1, 3, 10, 100 and 300 nM
Incubation time 4 days
Animal Experiment
Animal models mouse bearing SW620 xenografted tumors
Formulation methylcellulose/PBS
Dosages 10 mg/kg once daily for 5 consecutive days
Administration orally
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

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.
