There is an increased interest in the development of innovative strategies to combat Neglected Tropical Diseases (NTDs) due to the appearance of resistance to current medicines and the fact that NTDs affect approximately one-sixth of the world’s population. The Drennan lab, in collaboration with the Nonato lab at the University of Sao Paulo, are investigating class I (iron-sulfur cluster containing) fumarate hydratase (FH) from Leishmania major, the parasite responsible for cutaneous leishmaniases. FHs play crucial roles in parasite metabolism and are distinct from the class II FHs that are found in humans. The latter suggests that selective inhibition of class I FHs is feasible, thus offering a new perspective for the development of anti-leishmaniasis therapies.
