摘要
The current invention comprises compositions and methods for protecting a neuronal cell of a subject from a toxic insult. The method includes delivering an effective amount of a neuroprotective compound to the neuronal cells before or after the toxic insult. The neuroprotective compounds contain a peroxisome proliferator activated receptor (“PPAR-&ggr;”) binding moiety with either a phenolic ring moiety or a prostaglandin (“PG”) with a reactive &agr;,&bgr;-unsaturated carbonyl group on the cyclopentenone ring. Other novel compounds are also disclosed. The toxic insult that impinges upon the neuronal cell may be an acute process, or chronic disease process. Oxidative stress (e.g. hydrogen peroxide, and glutamate), injury, and secondary physiological responses to injury are among the acute processes discussed. Clinical disease processes that comprise oxidative stress, inflammatory responses, strokes, Alzheimer's disease, dementia, and Parkinson's disease are also addressed. Because PPAR-&ggr; agonists are used to treat type II diabetes, a condition that leads to neurological complications, a single agent that can target both conditions is of great therapeutic value.
