In Vitro	L-161982 (10 μM; 2 hours) blocks PGE2-stimulated cell proliferation of HCA-7 cells[1]. L-161982 (10 μM; 1 hour) blocks PGE2-stimulated ERK phosphorylation in HCA-7 cells[1]. L-161982 induces apoptosis, cell cycle arrest, and inhibits prostaglandin E2-induced proliferation in oral squamous carcinoma Tca8113 cells[3]. Cell Proliferation Assay[1] Cell Line: HCA-7 cells Concentration: 10 μM Incubation Time: 2 hours Result: Blocked PGE2-induced cell proliferation.
In Vivo	L-161982 (5 mg/kg; i.p.; once per day for 2 weeks) reduces arthritis lesions and lesion progression in CIA mice[2]. Animal Model: Female DBA/1 mice of 6 to 8 weeks old (collagen-induced arthritis (CIA) mice model)[1] Dosage: 5 mg/kg Administration: i.p.; once per day for 2 weeks Result: Showed less joint swelling and lower arthritis score after 35 days post immunization.
