Compounds described herein may be used for the treatment of neurodegenerative diseases linked to
protein misfolding, including prion diseases, Alzheimer's
disease, Parkinson's
disease (PD) and
amyotrophic lateral sclerosis (ALS), and also other neurodegenerative, degenerative, metabolic and ischemic conditions. Indeed, NAD
metabolism impairment is also a critical feature in
brain ischemia /
reperfusion injury, Wallerian degeneration,
kidney failure,
multiple sclerosis, aging, and metabolic disorders such as
diabetes mellitus. Therapies that elevate or stabilize NAD levels may thus have broad potential for treating many severely debilitating neurological and metabolic conditions. Evidence is provided herein with compounds from 8 lead series for NAD restoring properties and for therapeutic
efficacy in cellular and / or animal models of prion
disease, PD and ALS.
