ABT-239 is an H₃-receptor inverse agonist developed by Abbott. It has stimulant and nootropic effects, and has been investigated as a treatment for ADHD, Alzheimer's disease, and schizophrenia.^[1]^[2]^[3]^[4] ABT-239 is more active at the human H₃ receptor than comparable agents such as thioperamide, ciproxifan, and cipralisant. It was ultimately dropped from human trials after showing the dangerous cardiac side effect of QT prolongation,^[5] but is still widely used in animal research into H₃ antagonists / inverse agonists.
