guanethidine

Guanethidine sulphate was synthesized in 1959. Guanethidine is thought to lowing blood pressure by interfering with the metabolism of chemical transmitter substances in post-ganglionic sympathetic nerve fibres.

Ablation of sympathetic fibers is associated with a loss of rat endothelial cell marker (RECA), but no significant effect of guanethidine was found on the survival of endothelial cells and mesenchymal stem cells in vitro[1]. .

Guanethidine (30 mg/kg, s.c., 1 h) unaffected IL-18 hypernociception in TNFR1(-/-) mice as a sympathetic blocker[2]. . Animal Model: Wild-type (WT) Balb/c,TNFR1(-/-)and IFN-γ-γ(-/-) mice[2]. Dosage: 30 mg/kg Administration: Guanethidine (30 mg/kg, s.c., 1 h, diluted in saline) Result: Pre-treatment with guanethidine (sympathetic blocker) unaffected IL-18 hypernociception in TNFR1(-/-) mice.
