Leishmaniasis is an infectious disease caused by protozoan parasites of the genus Leishmania. There is no vaccine against human leishmaniasis and the treatment of the disease would benefit from a broader spectrum and a higher efficacy of leishmanicidal compounds. We analyzed the leishmanicidal activity and the mechanism of action of the calcium ionophore, calcimycin. L. major promastigotes were...

This review addresses the search for activity enhancement of leishmanicidal organic compounds through their coordination chemistry with ruthenium. In an introduction to leishmaniasis, its clinical manifestations, geographical distribution, available forms treatment, and challenges disease management are presented. Ruthenium complexes, owing physico-chemical biological properties, introduced as ...

Hexadecylphosphocholine (miltefosine), a membrane-active alkylphospholipid, may be the first effective oral agent for visceral leishmaniasis, an intracellular protozoal infection of tissue macrophages. In vitro, miltefosine stimulates T cells and macrophages to respond to and secrete activating cytokines, including interferon (IFN)-gamma, and enhances macrophage production of microbicidal react...
