Recent Advances in Metal Complexes Based on Biomimetic and Biocompatible Organic Ligands against Leishmaniasis Infections: State of the Art and Alternatives

Resumen

Leishmaniasis is a complex disease present in a variety of manifestations listed by the World Health Organization (WHO) as one of the neglected diseases with a worse prognosis if not treated. Medicinal inorganic chemistry has provided a variety of drugs based on metal-organic complexes synthesized with different metal centers and organic ligands to fight against a great number of parasite maladies and specifically Leishmaniasis. Taking advantage of the natural properties that many metals present for biotechnological purposes, nanotechnology has offered, in recent years, a new approach consisting on the application of metal nanoparticles to treat a great number of parasitic diseases, as a drug vehicle or as a treatment themselves. The aim of this review is to gather the most widely used metal complexes and metallic nanoparticles and the most recent strategies proposed as antileishmanial agents.
