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

This study was performed to delineate the kinin (receptor)-dependent pathways in the Indian red scorpion (Mesobuthus tamulus; MBT) venom-induced pulmonary oedema as well as the augmentation of cardio-pulmonary reflexes evoked by phenyldiguanide (PDG). In urethane-anaesthetized adult rats, the effect of

Adrenaline is an important counter-regulatory hormone that helps restore glucose homeostasis during hypoglycaemia. However, the neurocircuitry that connects the brain glucose sensors and the adrenal sympathetic outflow to the chromaffin cells is poorly understood. We used electrical microstimulation of the

Stimulation of cardiopulmonary receptors with phenylbiguanide (PBG) elicits depressor cardiovascular reflex responses, including decreases in blood pressure and heart rate mediated in part by the brain stem parasympathetic cardiac neurons in the nucleus ambiguus (NAmb). The present study examined NAmb
