LY-293284, also known as 4,α-methylene-5-acetyl-DPT, is a research chemical developed by the pharmaceutical company Eli Lilly and used for scientific studies. It acts as a potent and selective 5-HT_1A receptor full agonist. It was derived through structural simplification of the ergoline based psychedelic LSD, but is far more selective for 5-HT_1A with over 1000× selectivity over other serotonin receptor subtypes and other targets. It has anxiogenic effects in animal studies.
