Overview

Crisdesalazine is a multi-target drug that removes both free radicals and inflammation, which are proven contributors to Alzheimer’s disease and other neurodegenerative brain diseases.
Pharmacological action: (1) next-generation anti-inflammatory effect through inhibition of mPGES-1; (2) Remove free radicals (antioxidant)
Safety and anti-inflammatory effects are substantially improved with few adverse drug effects compared to nonsteroidal anti-inflammatory drugs (NSAIDs).
Demonstration of efficacy in animal models of neurodegenerative diseases.
Significant inhibition of ATN (A: Amyloidopathy, T: Tauopathy, N: Neurodegeneration), important pathological and diagnostic markers of AD in cultured cells and mouse models of dementia.
Demonstration of improvement in cognitive function in pet dogs with canine cognitive dysfunction syndrome, a canine disease with strong clinical and pathological parallels to human Alzheimer’s disease.
