Comment: UE2343 is an oral, brain-penetrant hydroxysteroid 11-beta dehydrogenase 1 (11-βHSD1) inhibitor that was developed to reduce brain levels of the stress hormone cortisol, as a mechanism to improve memory in Alzheimer's disease patients [1-2]. It failed to provide efficacy in a phase 2 clinical trial.

Bioactivity Comments
In a screen against a range of enzymes and receptors (including the glucocorticoid and mineralocorticoid receptors) UE2343 was selective for 11β-HSD1, with little inhibitory activity towards CYP450 isoforms 1A2, 2D6, 2C9 or 3A4, or the hERG channel [2].
