Conessine
Based on 1 Customer Validation
Conessine is an orally active and BBB-penetrable selective histamine H3 receptor antagonist. The pKi values of Conessine for rat and human H3 receptors are 7.61 and 8.27, respectively. Conessine is an inhibitor of the multidrug efflux pump system in Pseudomonas aeruginosa and can enhance the activity of antibiotics. Conessine has antimalarial activity. Conessine can also be used in the research of muscle atrophy.

Actividad biológica
Conessine (2.5-20 μM; 24 h) inhibits p53-, NF-κB-, and FoxO3a-dependent transcription in HEK293 cells[1].
Conessine (10 μM) reduces the levels of MuRF1 and atrogin-1 in Dexamethasone (HY-14648)-treated C2C12 myotube cells[1].
Conessine (72 h) has antimalarial activity, with IC50 values of 1.9 and 1.3 μg/mL in the schizont maturation method and pLDH assay, respectively[2].
Conessine (74 h) is cytotoxic to L-6 cells, with an IC50 of 14 μg/mL[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Conessine (0.1-10 mg/kg; subcutaneously; single dose) can exacerbate ethanol-induced psychostimulant effects in mice[3].

-
Animal Model:BALB/c mice aged 4-6 weeks old (22-26 g) were infected with Plasmodium berghei[2]
-
Dosage:10, 20 and 50 mg/kg
-
Administration:Oral administration; 4 days
-
Result:Significantly reduced parasitaemia in infected mice. The parasite inhibition rates were 88.95% at 10 mg/kg, 56.6% at 20 mg/kg, and 50.99% at 50 mg/kg on day 7. The mean survival time of mice in the 10 mg/kg group was 13.3 days, in the 20 mg/kg group was 11.6 days, and in the 50 mg/kg group was 11.5 days.
Affected the liver and kidney function of mice, as shown by the changes in the levels of alkaline phosphatase (ALP), bilirubin, urea, and creatinine in serum.
-
Animal Model:Male Swiss mice (30-35 g) treated ethanol[3]
-
Dosage:0.1, 1 and 10 mg/kg
-
Administration:Subcutaneously; single dose
-
Result:Exacerbated ethanol effects on locomotor activity in a dose-dependent manner.
Had reinforcing proprieties per se in the conditionedplace preference (CPP) procedure at dose of 10 mg/kg, but it did not alter the acquisition of ethanol CPP.
Blocked ethanol effects on dopaminergic and noradrenergic neurotransmission.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.01 mM); Clear solution
