Antipsychotic drugs — which transformed mental health care following their chance discovery in the mid-20th Century — may finally be poised for a long-overdue makeover incorporating structure-based design. Scientists funded by the National Institutes of Health have achieved a landmark of psychiatric neuropharmacology: deciphering the molecular structure of a widely prescribed antipsychotic docked in its key receptor. They are hopeful that this discovery may hold secrets to designing better treatments for schizophrenia, bipolar disorder, and other mental illnesses.
“For the first time, we can understand precisely how atypical antipsychotic drugs bind to their primary molecular target in the human brain,” explained Dr. Laurie Nadler, chief of the neuropharmacology program at the National Institute of Mental Health (NIMH), which co-funded the study along with the National Institute of General Medical Sciences and the National Cancer Institute. “This discovery opens the way for the rational design of a new generation of antipsychotic drugs, hopefully with more desirable effects and fewer side effects.”
