Emestedastat (proposed brand name Xanamem; developmental code name UE-2343) is a steroidogenesis inhibitor which is under development for the treatment of major depressive disorder, Alzheimer's disease, and fragile X syndrome.^[1]^[2] It specifically acts as a centrally penetrant inhibitor of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) and thereby inhibits the synthesis of the glucocorticoid steroid hormone cortisol.^[1]^[3]^[4]^[2] As of August 2024, emestedastat is in phase 2 clinical trials for major depressive disorder and Alzheimer's disease and is in the preclinical stage of development for fragile X syndrome.^[1]^[2] Clinical effectiveness for Alzheimer's disease has been mixed.^[2] It was originated by the University of Edinburgh and is being developed by Actinogen Medical.^[1]
