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

Sympathetic overdrive is a key player in hypertension, where the mesenteric vasculature plays a relevant role in modulating blood pressure. Although 5-HT inhibits noradrenergic mesenteric neurotransmission in normotensive rats, its effect on the mesenteric sympathetic drive in hypertensive rats has

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
