| 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. | | 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).
