UH-301 is a drug and research chemical widely used in scientific studies. It acts as a selective 5-HT1A receptor silent antagonist.[1] It is structurally related to 8-OH-DPAT.[1] UH-301 was found to produce a head-twitch response in mice which is usually typical of 5-HT2A agonist drugs, and has subsequently been used to investigate how 5-HT1A receptor activity modulates 5-HT2A receptors downstream.[2]
