General description

1-Phenylbiguanide is a 5-hydroxytryptamine receptor agonist and increases extracellular dopamine release in rat nucleus accumbens in vivo. It serves as building block for synthesis of heterocyclic compounds.

Application

1-Phenylbiguanide was used in one pot synthesis of :
  • 4-chloro-2,5-dihydro-2,5-dioxonaphtho[1,2-d]imidazole-3-carboxylic acid phenyl amide
  • 6-chloro-8-phenylamino-9H-7,9,11-triaza-cyclohepta[a]naphthalene-5,10-dione
  • 4-dimethylamino-5,10-dioxo-2-phenylimino-5,10-dihydro-2H-benzo[g]quinazoline-1-carboxylic acid amide

Three polymorphic modifications of bis(N-phenylbiguanidium(1+)) oxalate are reported, and their characterization is discussed in this paper. The non-centrosymmetric bis(N-phenylbiguanidium(1+)) oxalate (I), which was obtained from an aqueous solution at 313K, belongs to the monoclinic space group Cc (a=6.2560(2)Å, b=18.6920(3)Å, c=18.2980(5)Å

The serotonin-3 (5-HT3) agonist 1-phenylbiguanide (0.1-1.0 mM in perfusate) caused a robust, dose-dependent enhancement of extracellular dopamine content in nucleus accumbens as measured by in vivo microdialysis. This action was antagonized by co-perfusion of the 5-HT3 antagonists zacopride and GR38032F
