Omidenepag Isopropyl (CAS 1187451-19-9) is a selective, non-prostaglandin EP2 receptor agonist developed for the treatment of glaucoma and ocular hypertension. Chemically known as isopropyl (5-{[4-(1,3-benzothiazol-2-yl)piperazin-1-yl]carbonyl}-1,2-benzoxazol-3-yl)acetate, Omidenepag Isopropyl features a complex benzoxazole core linked to a piperazine-benzothiazole moiety via an amide bond.
Omidenepag Isopropyl is a novel ocular hypotensive agent and certified reference standard developed for the treatment of glaucoma. As the active pharmaceutical ingredient in the ophthalmic solution marketed as Eybelis® in Japan, Omidenepag Isopropyl provides effective intraocular pressure lowering in patients with open-angle glaucoma. In pharmaceutical quality control contexts, Omidenepag Isopropyl serves as the primary reference standard for impurity profiling, analytical method development, and regulatory submissions. Omidenepag Isopropyl is recognized through multiple regulatory designations including INN and JAN, making it indispensable for quality control testing. The drug substance Omidenepag Isopropyl exhibits excellent stability when stored under recommended conditions, with its prodrug form ensuring optimal ocular bioavailability. Furthermore, Omidenepag Isopropyl functions as a selective EP2 receptor agonist—a distinct mechanism from latanoprost and other FP receptor agonists—demonstrating the therapeutic versatility of this well-characterized molecular scaffold.

Product Advantages
Novel Non-Prostaglandin EP2 Agonist
Omidenepag Isopropyl represents a new class of ocular hypotensive agents that selectively target the EP2 receptor—a distinct mechanism from conventional prostaglandin FP receptor agonists. This unique mechanism offers an alternative for patients who may not respond adequately to latanoprost or other prostaglandin analogs.
Prodrug Design for Enhanced Ocular Bioavailability
The isopropyl ester prodrug form of Omidenepag Isopropyl ensures optimal corneal penetration following topical ophthalmic administration. Following absorption, Omidenepag Isopropyl is rapidly hydrolyzed to the active metabolite omidenepag, which binds to EP2 receptors in the trabecular meshwork.
Clinically Validated Efficacy
Omidenepag Isopropyl is approved in Japan as Eybelis® for the treatment of open-angle glaucoma, validating its safety and efficacy in clinical practice. The well-characterized pharmacological profile supports its use as a reference standard for glaucoma research.
Dual-Use: API and Reference Standard
Cosperpharm supplies Omidenepag Isopropyl at high-purity grade for use in both research applications and as an analytical reference standard for method development and quality control programs.
FAQ
Q1: What is the mechanism of action of Omidenepag Isopropyl?
A: Omidenepag Isopropyl is a selective non-prostaglandin EP2 receptor agonist. Upon ocular administration, it is hydrolyzed to the active metabolite omidenepag, which binds to EP2 receptors in the trabecular meshwork, increasing aqueous humor outflow and reducing intraocular pressure.
Q2: What are the primary therapeutic indications for Omidenepag Isopropyl?
A: Omidenepag Isopropyl is indicated for the treatment of open-angle glaucoma and ocular hypertension. It is marketed as Eybelis® ophthalmic solution in Japan.
