Cell experiment [1]: | |
Cell lines |
the electrically stimulated mouse vas deferens |
Preparation method |
This compound is soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
Reacting condition |
3 μM |
Applications |
In the electrically stimulated mouse vas deferens, Guanethidine sulfate inhibited twitching by 95%±3% in 15 min, but this effect was only partially reversed after 1 h of washing (33%±12% of control). |
Animal experiment [1]: | |
Animal models |
Myocardial infarction (MI) rat model |
Dosage form |
low-dose [LG], 1 mg/kg/day; medium-dose, 3 mg/kg/day; high-dose, 10 mg/kg/day; administered via an osmotic mini-pump for 4 weeks |
Application |
In myocardial infarction (MI) rats, LG suppressed left ventricular (LV) dilation (9.2±0.9 mm vs.11.0±0.8 mm) and improved LV fractional shortening (25.0±4.5% vs. 16.4±4.7%) in association with a reduction of plasma NE levels (520±250 pg/ml vs.1,000±570 pg/ml). Low-dose guanethidine reduced 24-h (6%) and 28-day mortality (6%). High-dose guanethidine also reduced 24-h mortality (12%) but increased 28-day mortality (91%). |
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Guanethidine Sulfate is an anti-hypertensive drug involved in reducing the release of catecholamines such as norepinephrine [1].
In vitro: Guanethidine (0.1 and 1 μM) decreased S-I efflux but increased resting efflux in a concentration dependent manner[1].On the electrically stimulated mouse vas deferens, Guanethidine (3 μM) treatment inhibited twitching by 95% ± 3% in 15 min, but this effect was only partially reversed after 1 h of washing (33% ± 12% of control). When guanethidine were used in combination with prilocaine, a reversal of 80% ± 13% (at 1 h) was observed. When co-incubated with guanethidine (3 μM), the twitch was reduced to 24% ± 4% of control and was reversed to 77% ± 7% after 1 h. The reversal produced by the combination was significantly more intense (P < 0.05) when compared with guanethidine alone. Local anesthetics reduced the sympatholytic actions of guanethidine, and this could explain the variable efficacy of guanethidine in the treatment of complex regional pain syndrome [2].
