Emixustat hydrochloride
Based on 1 Customer Validation
Emixustat (ACU-4429) hydrochloride is an orally active RPE65 inhibitor with an IC50 value of 4.4 nM. Emixustat hydrochloride is also a visual cycle modulator, capable of regulating visual cycle activity by inhibiting retinol isomerization, and holds potential for studying vision disorders such as age-related macular degeneration (AMD).

Biological Activity
IC50: 4.4 nM (Retinal Pigment Epithelium 65-kDa protein (RPE65))[4]
Emixustat (0.1 nM - 10 μM, 1 h) concentration-dependently reduces the production of 11-cis-retinol, thereby inhibiting RPE65 activity[4].
