Pb-22, the structure of QUPIC appears to utilise an understanding of structure-activity relationships within the indole class of cannabimimetics, although its design origins are unclear.
QUPIC represents a structurally unique synthetic cannabinoid chemotype, since it contains an ester linker at the indole 3-position, rather than the precedented ketone of JWH-018 and its analogues, or the amide of SDB-001 and its analogues. PB-22 became popular in 2013 due to its worldwide legality.
This is absolutely new and legal cannabinoid with very good properties. It can be compared to AKB-48.
