Leishmaniasis is a major health problem that affects populations of ∼90 countries worldwide, with no vaccine and only a few moderately effective drugs. Here we report the structure/function characterization of sterol 14α-demethylase (CYP51) from Leishmania infantum. The enzyme catalyzes removal of
The in vitro activity on Leishmania infantum promastigotes and Trypanosoma cruzi epimastigotes of 25 semisynthetic terpenoid derivatives has been evaluated. These compounds were obtained through chemical modifications of the major components of Euphorbia resinifera (alpha-euphol and alpha-euphorbol)
