Alzheimer’s drug candidates reverse broader aging

CMS121 and J147, two drug candidates that improve memory and slow neurodegeneration associated with Alzheimer's disease, also slow aging in healthy, older mice. The compounds block damage to neurons caused by general aging and restore levels of specific molecules to those seen in younger animals.

Drugs that quell brain inflammation reverse dementia

A synthesized small-molecule drug blocks the TGF-beta receptor in astrocytes and traverses the blood-brain barrier in mice. When administered, the drug lowered receptor activity to that seen in younger mice and reduced inflammation. The aged mice were able to navigate mazes and learn spatial tasks as well as younger mice.
