am-7438 am-7438 am-7438 is a drug which is a cannabinoid receptor agonist, developed by the research team led by dr alexandros makriyannis. it is a derivative of δ8-thc which has been substituted with a side chain containing a metabolically labile ester group, allowing the molecule to be rapidly metabolised to an inactive form, in a similar manner to drugs such as remifentanil, remimazolam and sn 35210. this means that while am-7438 retains potent cannabinoid effects, it has a much shorter duration of action than most related compounds. am-7438identifiers iupac name 3-cyanopropyl 2-chromen-3-yl]-2-methylpropanoate pubchem cid89994983chemblchembl4071389chemical and physical dataformulac24h31no4molar mass397.515 g·mol−13d model (jsmol)interactive image smiles cc1=cc2(c1)c3=c(c=c(c=c3oc2(c)c)c(c)(c)c(=o)occcc#n)o inchi inchi=1s/c24h31no4/c1-15-8-9-18-17(12-15)21-19(26)13-16(14-20(21)29-24(18,4)5)23(2,3)22(27)28-11-7-6-10-25/h8,13-14,17-18,26h,6-7,9,11-12h2,1-5h3/t17-,18-/m1/s1key:pgsjgfyqnypkoj-qztjidsgsa-n
