|  |  | Di-o-tolylguanidine Usage And Synthesis | 
 | Description | 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. |  | Uses | DTG is a selective ligand for the sigma-binding site. DTG has high binding affinity. |  | Definition | ChEBI: 1,2-bis(2-methylphenyl)guanidine is a member of toluenes. |  | General Description | 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 | Nonflammable |  | Biological Activity | Displays high and roughly equal affinity for both σ 1 and σ 2 receptors. |  | Safety Profile | Poison by ingestion and 
intraperitoneal routes. When heated to 
decomposition it emits toxic fumes of NOx. |  | Purification Methods | The guanidine crystallises from aqueous EtOH. The sulfate has m 253-254o(dec, H2O).
