A long-standing collaboration with Dr. Wolff Arzneimittel has resulted in a nice paper in the Journal of Medicinal Chemistry.

This project aimed at the development of novel κ agonists restricted to the periphery.

In the discovery stage of the project, a diastereo- and enantioselective synthesis of (4aR,5S,8aS)-configured decahydroquinoxalines was developed. Fine-tuning of physicochemical and pharmacological properties was executed by a team of medicinal chemists at Mercachem.

Anita Wegert, Project Manager in Medicinal Chemistry, explains “The methanesulfonamide 2a containing the (S)-configured hydroxypyrrolidine ring was investigated in two mouse models of dermatitis. The compound was identified as a potent (Ki = 0.63 nM) and highly selective κ agonist (EC50 = 1.8 nM), selective for the periphery, with dose-dependent anti-inflammatory activity in acute and chronic skin inflammation.”

In a joint effort, three different Mercachem business units cracked the challenging synthesis (Discovery Chemistry), optimized the synthetic route (Process Research), and performed lead optimization (Medicinal Chemistry).
