Mechanism of action
Eflornithine appears to kill trypanosomes by acting as a suicide inhibitor of the enzyme ornithine decarboxylase, this enzyme regulates cell division by catalysing the first step in polyamine biosynthesis.
Eflornithine effects against Trypanosoma brucei gambiense were discovered by chance and because its ability to bring patients back from the coma, it became known as “Resurrection Drug”.
