20-ethyl Prostaglandin E2 - CAS 37492-24-3

20-Ethyl Prostaglandin E2 (20-ethyl PGE2) is an analog of Prostaglandin E2 (PGE2) characterized by an extended ω-chain due to two additional methylene carbon atoms. Compared to unoprostone, a clinically approved glaucoma medication and the only extensively studied prostaglandin analog sharing this structural modification, 20-ethyl PGE2 maintains the natural 15 (S) allylic hydroxyl in its lower side chain, potentially enhancing its effectiveness. Unoprostone, despite being an F-series prostaglandin, exhibits reduced affinity for FP receptors because of its lower side chain modifications (13,14-dihydro-15-keto), which diminishes its medicinal potency. Notably, 20-ethyl PGE2's efficacy relative to unoprostone and its interaction with EP or other prostanoid receptors remains unconfirmed due to the lack of published ligand binding assays. E-type prostaglandins, including 20-ethyl PGE2, are broadly acknowledged for their inflammatory, cytoprotective, and diverse biological activities.
