Butaprost is a chemical compound that functions as a selective agonist for the prostaglandin E receptor (EP2). It exhibits an EC50 of 33 nM and a Ki of 2.4 μM when interacting with the murine EP2 receptor. However, Butaprost demonstrates lower activity against murine EP1, EP3, and EP4 receptors. Furthermore, it effectively attenuates fibrosis by inhibiting the TGF-β Smad2 signaling pathway [1] [2] [3].
Ono 1301 is a prostaglandin I2 mimetic coumpound with inhibitory activity against thromboxane A2 synthase. Ono 1301 suppresses pancreatic fibrosis in the DBTC-induced CP model by inhibiting monocyte activity not only with induction of HGF but also by Ono
