ONO-AE3-208 surpresses the in vitro cell invasion and migration in a dose-dependent manner without affecting cell proliferation[2]. ONO-AE3-208 abolisheS CTGF in the presence of the EET synthesis inhibitor MS-PPOH. Arachidonic acid (AA) causeS dose-dependent dilation of the attached Af-Art, and this effect is blocked by ONO-AE3-208[3].

ACSL5 Mediates Adaptation to the Palmitic Acid-Enriched Pulmonary Microenvironment to Enhance Metastatic Breast Cancer Cell Survival and Lung Metastasis. [Abstract]2026 Jan 22. PMID: 41570334
ONO-AE3-208 purchased from MedChemExpress. Usage Cited in: Cancer Res. 2026 Jan 22. [Abstract]
BALB/c nude mice intravenously injected with shNC or shACSL5 LM3 cells were administered with PAC, celecoxib, and ONO-AE3-208 (10 mg/kg; p.o.) alone or in combination. Representative images are shown. The results showed that ACSL5 knockdown, celecoxib, ONO-AE3-208, or PAC dramatically mitigated lung metastasis, whereas targeting ACSL5, COX2, or EP4 in combination with PAC led to a more pronounced reduction in lung metastasis.

BALB/c nude mice intravenously injected with shNC or shACSL5 LM3 cells were administered with PAC, celecoxib, and ONO-AE3-208 (10 mg/kg; p.o.) alone or in combination. Overall survival are shown. The results showed that ACSL5 knockdown, celecoxib, ONO-AE3-208, or PAC dramatically mitigated lung metastasis, whereas targeting ACSL5, COX2, or EP4 in combination with PAC increased overall survival compared with PAC monotherapy.

Effects of ONO-AE3-208 on the expression of IL1B mRNA in macrophages stimulated with GCM from U251 and T98G cells (n = 3). Macrophages were pre-incubated with ONO-AE3-208 (0.1-5 μM), a selective EP4 receptor antagonist, for 30 min prior to treatment with GCM. After 24 h, IL1B mRNA expression was significantly reduced in macrophages treated with GCM derived from U251 or T98G cells in a dose-dependent manner when EP4 was blocked.
