1-(2-Diphenyl)piperazine also known as RA-7 is a drug which acts as a potent and selective agonist at the 5HT7 serotonin receptor. It was discovered as an active metabolite of the synthetic 5-HT7 agonists LP-12 and LP-211 and unexpectedly turned out to be a similarly potent agonist with selectivity approaching that of the parent molecules despite its much simpler structure.
