title: Novel potential drug against T. cruzi and its interaction with surfactant micelles.
abstract: The interaction of 5-nitro-2-furfurilylidene benzhydrazide (5NFB), potential anti-trypanosomal compound, with micellar solutions was studied. The results indicated that 50 mug of 5NFB completely kills 20 million T. cruzi epimastigote cells within 3 days, whereas the same amount of benznidazole kills 30% of the cells after 4 days. 5NFB solubility in surfactants solutions (SDS, DTAB, C12EO8) increased linearly with surfactant concentration. According to small angle X-ray scattering (SAXS), 5NFB does not affect micellar structural features. A comparison between C12EO8 effects on T. cruzi epimastigote cells and on erythrocytes showed that surfactant lytic effect is stronger in parasite cells, enlightening the potential of 5NFB micellar formulations.
