Cu(ATSM) Cuts Alzheimer’s Amyloid 42% and Restores Memory in Lab Studies
3 articles · Updated · ScienceDaily · Jun 22
Summary
Monash University researchers reported that Cu(ATSM) reduced amyloid-beta buildup by 42% over 56 days and improved long-term spatial learning by nearly 44% in an Alzheimer’s mouse model.
The copper-based compound increased blood-brain barrier P-glycoprotein clearance pumps by 24.1%, restoring part of the brain’s waste-removal system that normally expels toxic proteins into the bloodstream.
Cu(ATSM) may move relatively quickly toward Alzheimer’s trials because it has already undergone human safety testing for other neurological conditions, including Parkinson’s disease and ALS.
Researchers still need to show exactly how the cleared proteins leave the brain, and they are also investigating whether the drug boosts microglia activity to help break down amyloid plaques.
The findings add to efforts to develop new Alzheimer’s treatments as dementia has become Australia’s leading cause of death, underscoring the urgency of therapies that can slow cognitive decline.

How can copper, a metal that can cause neurological damage, be the key to restoring memory in Alzheimer's patients?
Is fixing the brain's own waste disposal system a better Alzheimer's strategy than delivering drugs with molecular 'shuttles'?
Cu(ATSM) Boosts Brain Waste Clearance by 24%: A Promising Preclinical Advance for Alzheimer’s Disease (June 2026)
Overview
Cu(ATSM) is a promising preclinical candidate for Alzheimer's disease, showing significant positive effects in animal models. Treatment with Cu(ATSM) leads to a substantial reduction in toxic amyloid-beta protein levels and improves cognitive function. This is achieved by increasing the abundance of P-glycoprotein clearance pumps at the blood-brain barrier, which helps repair the barrier and remove harmful proteins from the brain. Additionally, Cu(ATSM) may boost the activity of microglia, the brain's immune cells, further supporting the breakdown of toxic plaques and enhancing cognitive abilities.
