Antiprotozoal compounds from Mikania periplocifolia (Asteraceae).

Chagas disease, African trypanosomiasis and Leishmaniasis are neglected parasitic diseases which affect millions of people worldwide. In a previous work, we report the antiprotozoal activity of the dichloromethane extract of Mikania periplocifolia Hook. & Arn.

Identification and biochemical characterization of an ATP-dependent dihydroxyacetone kinase from Trypanosoma cruzi.

Dihydroxyacetone (DHA) can be used as an energy source by many cell types; however, it is toxic at high concentrations. The enzyme dihydroxyacetone kinase (DAK) has shown to be involved in DHA detoxification and osmoregulation. Among protozoa of the genus Trypanosoma, T.
