The activities of four anticancer alkyllysophospholipids against Leishmania donovani, Trypanosoma cruzi and Trypanosoma brucei

Abstract

The in-vitro activities of four anticancer alkyllysophospholipids, ET-18-OCH3 (edelfosine), hexadecylphosphocholine (miltefosine), ilmofosine and SRI 62-834, were determined with ED50 values for Leishmania donovani and Trypanosoma cruzi amastigotes between 0.2 and 5.0 μM and for Trypanosoma brucei trypomastigotes between 7.0 and 50.8 μM. In BALB/c mice miltefosine and ilmofosine were the most active compounds with ED50 values of 2.9 and 14.5 mg/kg x 5 doses against L. donovani and a suppressive effect on T. cruzi infections at 30 mg/kg x 5 doses.
