o-1602 o-1602 o-1602 is a synthetic compound most closely related to abnormal cannabidiol, and more distantly related in structure to cannabinoid drugs such as thc. o-1602 does not bind to the classical cannabinoid receptors cb1 or cb2 with any significant affinity, but instead is an agonist at several other receptors which appear to be related to the cannabinoid receptors, particularly gpr18 and gpr55. these previously orphan receptors have been found to be targets for a number of endogenous and synthetic cannabinoid compounds, and are thought to be responsible for most of the non-cb1, non-cb2 mediated effects that have become evident in the course of cannabinoid research. o-1602 produces some effects shared with classical cannabinoid compounds such as analgesic and antiinflammatory effects and appetite stimulation, but it does not produce sedation or psychoactive effects, and has several actions in the gut and brain that are not shared with typical cannabinoid agonists. o-1602identifiers iupac name 5-methyl-4-benzene-1,3-diol cas number317321-41-8pubchem cid45073499iuphar/bps5525chemspider23014383chemical and physical dataformulac17h22o2molar mass258.16 g·mol−13d model (jsmol)interactive image smiles cc1=c(c2=c(c)c=c(o)c=c2o)(c(c)=c)cc1 inchi inchi=1s/c17h22o2/c1-10(2)14-6-5-11(3)7-15(14)17-12(4)8-13(18)9-16(17)19/h7-9,14-15,18-19h,1,5-6h2,2-4h3/t14-,15+/m0/s1key:kdzousulxzndjh-lsdhhaiusa-n
