7,n,n-tmt 7,n,n-tmt 7,n,n-trimethyltryptamine (7-methyl-dmt, 7-tmt), is a tryptamine derivative which acts as an agonist of 5-ht2 receptors. in animal tests, both 7-tmt and its 5-methoxy derivative 5-meo-7-tmt produced behavioural responses similar to those of psychedelic drugs such as dmt, but the larger 7-ethyl and 7-bromo derivatives of dmt did not produce psychedelic responses despite having higher 5-ht2 receptor affinity in vitro (cf. dobu, doam). 7-tmt also weakly inhibits reuptake of serotonin but with little effect on dopamine or noradrenaline reuptake. 7,n,n-tmtidentifiers iupac name 2-(7-methyl-1h-indol-3-yl)-n,n-dimethylethanamine cas number65882-39-5 ypubchem cid47747chemspider43445 yuniif9r59mt42echemblchembl20167 ycomptox dashboard (epa)dtxsid50216078 chemical and physical dataformulac13h18n2molar mass202.301 g·mol−13d model (jsmol)interactive image smiles cc1=c(nc=c2ccn(c)c)c2=cc=c1 inchi inchi=1s/c13h18n2/c1-10-5-4-6-12-11(7-8-15(2)3)9-14-13(10)12/h4-6,9,14h,7-8h2,1-3h3 ykey:pqsftucfmwbitk-uhfffaoysa-n y ny (what is this?)
