Isoorientin is a Selective Inhibitor of Cyclooxygenase-2 (COX-2) from the Tubers of Pueraria tuberosa[1]. PANC-1 and PATU-8988 cells are grown for 24 hours in the presence of Isoorientin (0, 20, 40, 80, and 160 μM), and a CCK8 solution is added. The cell viability decreases significantly at the concentrations of 20, 40, 80, and 160 μM. After the cells are cultured with Isoorientin (0, 20, 40, 80, and 160 μM for PANC-1; 0, 20, 40, 80, 160, and 320 μM for PATU-8988) for 24 hours, the expression of p-AMPK and AMPK is assessed by Western blotting. After the Isoorientin treatment, the p-AMPK expression is increased. Then, in the shRNA group, the concentration of 80 μM is used to detect the effects of Isoorientin. The expression levels of AMPK and p-AMPK are much lower in the shRNA group than in the wild-type PC cells (WT) and the group that is transfected with a negative control lentivirus (NC)[2].

Protocolo
PANC-1 and PATU-8988 cells are plated onto 96-well plates. Each well contain ~5,000 cells and 200 μL of the medium with 10% FBS. When the cells of each well reach 70% confluency, the medium is changed, and FBS-free medium with different concentrations of Isoorientin is added. After 24 hours, the cells are washed with PBS once, the medium containing Isoorientin is discarded, and 100 μL of FBS-free medium with 10 μL of the Cell Counting Kit 8 (CCK8) reagent are added. The cells are incubated for another 1-2 hours at 37°C, and the absorbance of each well is detected using an ELISA reader at 490 nm. Cell viability is expressed as the fold change of absorbance[2].

Mice[3]
In the case of paw edema model the Isoorientin or Celecoxib is given intraperitoneally and Carrageenan is injected into the paw directly one hour later. In air pouch model all the treatments are given along with Carrageenan directly into the pouch cavity. Isoorientin is injected three hours earlier than injection of Carrageenan into the pouch cavity. Isoorientin and Celecoxib are administered into the mice air pouch. The stock solutions of Isoorientin (100?mg/mL) and Celecoxib (100?mg/mL) are prepared in DMSO and further dilutions are made at the time of treatments. Animals are divided, into 5 different groups as follows: control (DMSO treated); Carrageenan (0.5?mL of 1.5% (w/v) Carrageenan in saline) treated; Carrageenan+Celecoxib (20?mg/kg body weight) treated; Carrageenan+Isoorientin (10?mg/Kg body weight) treated; Carrageenan+Isoorientin (20?mg/Kg body weight) treated.
