Dihydroergocristine mesylate (DHEC mesylate) is a inhibitor of γ-secretase (GSI), reduces the production of the Alzheimer's disease amyloid-β peptides, binds directly to γ-secretase and Nicastrin with equilibrium dissociation constants (Kd) of 25.7 nM and 9.8 μM, respectively[1].

Description	Dihydroergocristine mesylate (DHEC mesylate) is a inhibitor of γ-secretase (GSI), reduces the production of the Alzheimer's disease amyloid-β peptides, binds directly to γ-secretase and Nicastrin with equilibrium dissociation constants (Kd) of 25.7 nM and 9.8 μM, respectively[1].

In Vitro	Dihydroergocristine (DHEC) (2-20 μM; 24 hours) has an IC50 value of 25 μM for inhibiting the activity of γ-secretase in T100 cells without affecting cell viability[1]. Dihydroergocristine (2-20 μM; 24 hours) inhibits cellular Aβ production and causes a dose-dependent accumulation of carboxy-terminal fragments of APP (APP-CTFs) in HEK293 and decreases γ-secretase activity in fibroblast cells[1]. Western Blot Analysis[1] Cell Line: WT HEK293 cells; Fibroblast cells Concentration: 2 μM, 5 μM, 10 μM, 20 μM Incubation Time: 24 hours Result: Increased APP-CTFs accumulation in a dose-dependent manner.
