Alazopeptin
Alazopeptin is a non-ribosomal tripeptide azoamino acid antibiotic isolated from various Streptomyces species, with significant anti-tumor, antibacterial and trypanocidal activities. Alazopeptin exhibits cytotoxicity against mouse leukemia cells and S-180 tumor cells, inhibits the growth of Bacillus subtilis, and shows activity against Trypanosoma brucei. Alazopeptin can be widely used in studies related to mouse leukemia, S-180 tumor, human African trypanosomiasis and nagana.

Biological Activity
|
Trypanosoma |
Alazopeptin exhibits moderate in vitro antitrypanosomal activity and low cytotoxicity against Trypanosoma brucei brucei strain GUTat 3.1 and Trypanosoma brucei rhodesiense strain STIB900[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Trypanosoma brucei brucei strain and Trypanosoma brucei rhodesiense strain STIB900
-
Concentration:IC50
-
Incubation Time:72 h
-
Result:Exhibied Trypanosoma brucei brucei strain GUTat 3.1 (IC50=0.51 μg/mL) and Trypanosoma brucei rhodesiense strain STIB900 (IC50=1.21 μg/mL), with low cytotoxicity against human MRC-5 cells (IC50 >9.10 μg/mL).
Alazopeptin (4.5-36.4 mg/kg; i.v.; daily; 7-10 days) dose-dependently inhibits S-180 solid tumor growth in dd mice[3].
Alazopeptin shows no detectable efficacy against Ehrlich ascites carcinoma in dd mice[3].
Alazopeptin (50 mg/kg; i.p.; daily; 4 consecutive days) does not cure T. b. brucei S427 infection in female ICR mice but increases mean survival day by 1.8-fold relative to controls[1].
