ONO-AE3-208 Usage And Synthesis

Uses

ONO AE3 208 is a prostaglandin E receptor EP4 antagonist, which inhibits breast cancer metastasis.

Biological Activity

ono-ae3-208 is an antagonist 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].
