DOI-NDEPA
DOI-NDEPA is a chemical compound of the phenethylamine, DOx, and NDEPA families. It is the N- derivative of the psychedelic drug DOI. The drug can also be thought of as a derivative of DOI with an LSD-like N,''N''-diethylamide moiety. A quantitative structure–activity relationship predicted that DOI-NDEPA would bind with high affinity to the serotonin 5-HT2A receptor. Its predicted affinity was 3.2nM. DOI-NDEPA was first described in the scientific literature by 1999.
