生物活性

DuP-697 is a member of the vicinal diaryl heterocycles and a potent, irreversible, selective and orally active COX-2 inhibitor (IC50 of 10 nM and 800 nM for human COX-2 and COX-1, respectively). DuP-697 exerts antiproliferative (IC50 of 42.8 nM), antiangiogenic and apoptotic effects on HT29 colorectal cancer cells. DuP-697 inhibits prostaglandin synthesis and has anti-inflammatory, anticancer and antipyretic effects[1][2][3].

体外研究
(In Vitro)

DuP-697 (0-100 nM; 24 hours; HT29 cells) treatment shows antiproliferative with an IC50 value of 42.8 nM[1].
DuP-697 (25-100 nM; 72 hours; HT29 cells) treatment causes concentration dependent apoptosis in HT29 cells. The percentage of UR (apoptosis portion) area increases gradually according to the concentration of DuP-697 from 7% in control group to 52% in 100 nM DuP-697[1].
DuP-697 in 100, 10 and 1 nM concentrations cause antiangiogenic effect. Antiangiogenic scores of DuP-697 are 1.2, 0.8 and 0.5, respectively[1].

Cell Proliferation Assay[1]

Cell Line: HT29 cells
Concentration: 0 nM, 12.5 nM, 25 nM, 50 nM, 100 nM
Incubation Time: 24 hours
Result: Exhibited decreasing CI values in a concentration dependent manner. Showed statistically significant cytotoxic effect.

Apoptosis Analysis[1]

Cell Line: HT29 cells

Incubation Time: 72 hours
Result: Caused concentration dependent apoptosis in HT29 cells.

体内研究
(In Vivo)

DuP-697 is a potent inhibitor of paw swelling in nonestablished and established adjuvant arthritis in rats (ED50 = 0.03 and 0.18 mg/kg/day, respectively). DuP-697 has no effect on phenylquinone writhing in rats (ED50 greater than 100 mg/kg), but is analgetic against inflammation-related pain in the Randall-Selitto assay (ED50 = 3.5 mg/kg) and is a very potent antipyretic agent (ED50 = 0.05 mg/kg). DuP-697 (5 mg/kg i.v.) does not alter renal blood flow or the renal vascular response to angiotensin II in furosemide-pretreated, volume-depleted rats[2].
DuP-697 is a moderate inhibitor of bull seminal vesicle prostaglandin (PG) synthesis (IC50 of 24 μM) and a potent inhibitor of rat brain PG synthesis (IC50 of 4.5 μM) but was ineffective against rat kidney PG synthesis (IC50 of 75 μM)[2].
