Background:

ONO-AE3-208 is an inhibitor of EP4 [1].

EP4 is one of the prostaglandin E2 receptors and is associated with inflammatory disease and cancer such as prostate cancer. As an antagonist of EP4, ONO-AE3-208 is expected to be a potential therapy for prostate cancer. In vitro assays show that ONO-AE3-208 can suppress the migration and invasion of prostate cancer cells. 10μM of ONO-AE3-208 decreases wound healing proportion of PC3 and LNCaP cell lines in wound-healing assay. And in Transwell Invasion assay, ONO-AE3-208 inhibits cell invasion even at concentration of 0.1μM. ONO-AE3-208 is also reported to suppress bone metastasis in vivo [1].

Since activation of E2 can increase the expression of matrix metalloproteinase (MMP) and release inflammatory cytokines, and then exacerbates abdominal aortic aneurism (AAA) formation, ONO-AE3-208 is also used in the studies of AAA formation. It has been proved that ONO-AE3-208 can cause the elastic fiber degradation and inhibit AAA formation in vivo in a dose-dependent manner [2].
