COX-2

| ln Vitro |
In the oral squamous carcinoma cell line KB, paradol ([6]-paradol) promotes apoptosis in a dose-dependent manner. Through a caspase-3-dependent mechanism, paradol promotes apoptosis [2].
|
| ln Vivo |
Giving 10 mg/kg of paradol (6-paradol) dramatically decreased the amount of Iba1-positive cells one and three days after the challenge. Moreover, even three days after the M/R challenge, paradol dramatically decreased the amount of Iba1-positive cells in the peri-ischemic region [3]. Of the many paradol compounds—2-, 4-, 6-, 8-, and 10-paradol—paradol (6-paradol) has the strongest anti-inflammatory activity. In addition, out of all the known analogues of Paradol, Paradol has the highest irritating qualities. Paradoll also demonstrated the longest exposure duration at the site of anti-obesity effect, according to the study's metabolite absorption results [4].

| Enzyme Assay |
Ginger roots have been used to treat inflammation and have been reported to inhibit cyclooxygenase (COX). Ultrafiltration liquid chromatography mass spectrometry was used to screen a chloroform partition of a methanol extract of ginger roots for COX-2 ligands, and 10-gingerol, 12-gingerol, 8-shogaol, 10-shogaol, 6-gingerdione, 8-gingerdione, 10-gingerdione, 6-dehydro-10-gingerol, 6-paradol, and 8-paradol bound to the enzyme active site. Purified 10-gingerol, 8-shogaol and 10-shogaol inhibited COX-2 with IC(50) values of 32 μM, 17.5 μM and 7.5 μM, respectively. No inhibition of COX-1 was detected. Therefore, 10-gingerol, 8-shogaol and 10-shogaol inhibit COX-2 but not COX-1, which can explain, in part, the anti-inflammatory properties of ginger [1].

| Cell Assay |
KB, human oral epidermoid carcinoma cell lines (ATCC CCL-17) are plated at a density of 5×103 cells/200 μL/well into 96-well plate. After an overnight growth, the cells are treated with a series of paradol derivatives. All of the derivatives of paradol tested are dissolved in DMSO. The final concentration of DMSO in the culture medium is kept below 0.1% and the controls are treated with DMSO alone. Cell viability is assessed using MTT assay. In brief, after the cells are grown in the media in the absence or presence of the test compounds (e.g., Paradol, 10, 50, 100, 150, and 200 μM) for 48 h, they are then replaced to a 200 μL culture medium containing 0.5 mg/mL MTT for 3 h. The resulting MTT-formazan product is dissolved by an addition of the same volume of DMSO. The amount of formazan is determined by measuring the absorbance at 570 nm[2].

| Animal Protocol |
Mice[3]
Male ICR mice (7 weeks old, 36±2 g) challenged with middle cerebral artery occlusion (MCAO)/reperfusion (M/R) are randomly divided into vehicle (10% Tween80)- or Paradol-administered groups (n=6~7 per group). Paradol dissolved in 10% Tween80 is orally administered (10 mg/kg) into mice at 1, 5, or 10 mg/kg immediately after reperfusion. Rats[4] Five-week-old Sprague-Dawley rats (male) are used. At 8 weeks of age, the rats are fasted for 14 h prior to the oral administration of olive oil (1 mL) containing zingerone or 6-, 8-, or 12-paradol (10 mg/kg). Three rats in each group are anesthetized with isoflurane, and samples (0.3 mL) of their blood are collected from their jugular vein using a heparinized needle and syringe at 0 (i.e., prior to the oral administration), 0.25, 0.5, 1, 3, 6, and 24 h after the oral administration of the olive oil containing test compounds. The AUC0-24h values determined using this time schedule are very similar compared with AUC0-24h that sampled the time points more minutely with other materials in our laboratory. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
