Tesofensine
Based on 1 Customer Validation
Tesofensine (NS-2330) is a triple monoamine reuptake inhibitor inducing a potent inhibition of the re-uptake process in the synaptic cleft of the neurotransmitters dopamine (DA; IC50=6.5 nM), norepinephrine (NE;IC50=1.7 nM), and serotonin (5-HT;IC50=11 nM), and with potentials as an anti-obesity agent. Tesofensine is a CNS acting anti-obesity agent.

Animal Model:Diet-induced obesity (DIO) rat[3]
-
Dosage:0.1-3 mg/kg
-
Administration:Administered subcutaneously (s.c.); a single dose (acute treatment)
-
Result:The threshold dose for inhibition of total food intake was 1.0 mg/kg.
The ED50 for inhibition of total food intake in DIO rats was estimated to be 1.3 mg/kg.
-
Animal Model:Diet-induced obesity (DIO) rat[3]
-
Dosage:2.0 mg/kg
-
Administration:Administered subcutaneously (s.c.) daily for over 16 days (chronic treatment)
-
Result:The average relative decrease in the body weight of tesofensine-treated DIO rats over the entire treatment period was 8.6±1.4%.
When comparing to vehicle controls, the relative weight loss with tesofensine was 13.8±1.4%.
