N2 - We report that the tuberculosis drug SQ109 [N-adamantan-2-yl-N′-((E)-3,7-dimethyl-octa-2,6-dienyl)-ethane-1,2-diamine] has potent activity against the intracellular amastigote form of Leishmania mexicana (50% inhibitory concentration [IC50], ∼11 nM), with a good selectivity index (>500). It is also active against promastigotes (IC50, ∼500 nM) and acts as a protonophore uncoupler, in addition to disrupting Ca2+ homeostasis by releasing organelle Ca2+ into the cytoplasm, and as such, it is an interesting new leishmaniasis drug hit candidate.
