DTG (97-39-2) is an agonist of the sigma (σ) receptor1?with roughly equal potency against both subtypes (σ1 and σ2 IC50’s ~ 30nM)2.
DTG is a selective ligand for the sigma-binding site. DTG has high binding affinity.
ChEBI: 1,2-bis(2-methylphenyl)guanidine is a member of toluenes.
1,3-Di-o-tolylguanidine is a selective σ-receptor agonist. 1,3-Di-o-tolylguanidine is σ site ligand and its interaction with dopamine drugs were studied in Wistar rats and Albino Swiss mice.
Flammability and Explosibility
Non flammable
Displays high and roughly equal affinity for both σ 1 and σ 2 receptors.
Poison by ingestion and
intraperitoneal routes. When heated to
decomposition it emits toxic fumes of NOx.
The guanidine crystallises from aqueous EtOH. The sulfate has m 253-254o(dec, H2O). [Beilstein 12 H 803, 12 II 445, 12 III 1871, 16 IV 1764]
