Biological Activity
20-Ethyl Prostaglandin E2 (20-ethyl PGE2) is an analog of Prostaglandin E2 (PGE2) characterized by an extended omega-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.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Use a bath-type ultrasonic cleaner at standard cleaning frequency (37–40 kHz). Bath sonication is gentler than a probe sonicator and avoids sample overheating. Sonicate in 5–10 second intervals, checking solubility between pulses, for no more than 2–3 minutes total. Warm the bath to 37 °C if solubility remains poor.
Generally, for molecules that require light-protected storage, we will ship them in amber glass bottles.
