Suberoylanilide hydroxamic acid (SAHA), which is FDA approved for the treatment of cancer under the trade name Zolinza®, was effective in restoring memory performance in this Alzheimer's disease (AD) model. 

SAHA was synthesized by Medicilon and was given to mice as 50 mg/kg doses. Injections (10 mL/kg) were given intraperitoneally and were alternated daily between left and right sides of the abdomen. Chronic treatments of SAHA completely restored performance deficits in APP/PS1 mice.
