ONO-RS-082 is an inhibitor of phospholipase A (PLA)[1]. ONO-RS-082 inhibits PLA2 with the IC50 of 1.0 μM, but does not inhibit PLC even at 100 μM[2].

In Vitro	ONO-RS-082 (10 μM) prevents P. aeruginosa strain PAO1-induced polymorphonumclear cells (PMNs) transepithelial migration, demonstrating that PLA2 activity is crucial to this process[3]. Cell Viability Assay[3] Cell Line: A549 lung epithelial cell lines Concentration: 10 μM Incubation Time: 2-h pretreatment Result: Completely blocked HXA3-mediated PAO1-induced PMN transepithelial migration. Largely prevented PAO1-induced PGE2 release.
In Vivo	In vivo long-term activation of KCNK3 by ONO-RS-082 (50 mg/kg/day; preventive treatment, day 0 to day 21) reduces the development of PH in the MCT-PH model[4]. In contrast, in vivo short-term KCNK3 activation by ONO-RS-082 (curative treatment) fails to reduce PH symptoms, which is attributed to the complete loss of KCNK3 expression in MCT-PH rats at days 14 to 21[4]. Animal Model: MCT- pulmonary hypertension (PH) rat model[4] Dosage: 50 mg/kg/day Administration: Result: Reduced the development of PH in the MCT-PH model for long-term.
