DuP-697 (S-6907 and BFMT) is an irreversible, selective and orally bioactive cyclooxygenase 2 (COX-2) inhibitor with the potential for the treatment of rheumatoid arthritis (RA) and osteoarthritis and with IC50 of 10 nM and 800 nM for human COX-2 and COX-1, respectively. DuP-697 alone exerted antiproliferative, antiangiogenic and apoptotic effects on HT29 colorectal cancer cells. DuP-697 significantly suppressed K562 cells and primary CML cells growth and induced apoptosis in a concentration-dependent manner and the growth-inhibiting effect was independent on Philadelphia chromosome. DuP-697, at concentrations ranges which do not inhibit PGHS-1 activity, significantly attenuated the inhibition of PGHS-1 that was caused by aspirin and indomethacin.
| ln Vitro |
Treatment of HT29 cells with DuP-697 (0-100 nM; 24 hours) demonstrated anti-proliferative effects with an IC50 value of 42.8 nM [1]. HT29 cells treated with DuP-697 (25-100 nM; 72 hours) undergo concentration-dependent apoptosis. UR (apoptotic fraction) area as a proportion of total area grew progressively with increasing DuP-697 concentration, from 7% in the control to 52% in 100 nM DuP-697 [1]. At doses of 100, 10, and 1 nM, DuP-697 exhibited anti-angiogenic properties. According to DuP-697, the anti-angiogenic scores are 1.2, 0.8, and 0.5, respectively[1].

| ln Vivo |
In rats with both confirmed and suspected adjuvant arthritis, DuP-697 is a strong inhibitor of paw swelling (ED50 0.03 and 0.18 mg/kg/day, respectively). In the Randall-Selitto assay, DuP-697 has analgesic effects on inflammation-related pain (ED50 = 3.5 mg/kg) and is a very effective antipyretic medication (ED50 = 0.05 mg/kg). However, it has no effect on benzoquinone writhing in rats (ED50 larger than 100 mg/kg). In volume-depleted rats pretreated with furosemide, DuP-697 (5 mg/kg iv) does not change renal blood flow or renal vascular responses to angiotensin II [2]. DuP-697 is not effective on rat kidney prostaglandin (PG) synthesis, but it is a powerful inhibitor of PG synthesis in the brain (IC50 = 4.5 μM) and a moderate inhibitor of PG synthesis in bull seminal vesicles (IC50 = 24 μM). (75 μM is the IC50)][2].

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

*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.
