quchic quchic quchic (bb-22, sgt-32 or 1-(cyclohexylmethyl)-1h-indole-3-carboxylic acid 8-quinolinyl ester) is a designer drug offered by online vendors as a cannabimimetic agent, and was first detected being sold in synthetic cannabis products in japan in early 2013, and subsequently also in new zealand. the structure of quchic appears to use an understanding of structure-activity relationships within the indole class of cannabimimetics, although its design origins are unclear. quchic, along with 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. quchiclegal statuslegal status ca: schedule ii de: anlage ii (authorized trade only, not prescriptible) nz: temporary class uk: class b identifiers iupac name 1-(cyclohexylmethyl)-1h-indole-3-carboxylic acid 8-quinolinyl ester cas number1400742-42-8pubchem cid71711120chemspider29339967uniieud4zlb25rcomptox dashboard (epa)dtxsid40856801 chemical and physical dataformulac25h24n2o2molar mass384.479 g·mol−13d model (jsmol)interactive image smiles c1ccc(cc1)cn2c=c(c3=cc=cc=c32)c(=o)oc4=cc=cc5=c4n=cc=c5 inchi inchi=1s/c25h24n2o2/c28-25(29-23-14-6-10-19-11-7-15-26-24(19)23)21-17-27(16-18-8-2-1-3-9-18)22-13-5-4-12-20(21)22/h4-7,10-15,17-18h,1-3,8-9,16h2key:rhygtjxohogqgi-uhfffaoysa-n pharmacology bb-22 acts as a full agonist with a binding affinity of 0.217nm at cb1 and 0.338nm at cb2 cannabinoid receptors.
