Azithromycin is an antibiotic for inhibition of parasite growth with IC50 of 8.4 μM.
Trypanosomes
T. congolense, T. b. brucei and T. evansi
Preparation method
The solubility of this compound in DMSO is > 30.1 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.
Reacting condition
0.32 ~ 25 μM; 72 hrs
Applications
The IC50 values of Azithromycin for T. congolense, T. b. brucei and T. evansi were 0.19 ± 0.17, 3.69 ± 2.26 and 1.81 ± 1.82 μM, respectively.
Animal models
Mice infected with T. congolense
Dosage form
50, 100, 200, 300 and 400 mg/kg; p.o.
In mice infected with T. congolense, Azithromycin dose-dependently killed T. congolense, with the initial clearance of the parasites from the peripheral circulation in all treatment groups. However, this was followed by a relapse resulting in the rapid growth of the parasites. On the other hand, the survival rate was significantly prolonged in all treatment groups. A number of mice survived in the 200, 300 and 400 mg/kg Azithromycin groups, while all mice in the control and the 50 and 100 mg/kg Azithromycin groups died.
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.
