Microalgae extracts: Potential anti-Trypanosoma cruzi agents?

Introduction: Chagas disease, caused by the protozoan parasiteTrypanosoma cruzi, has no effective treatment available. On the other hand, microalgae are aquatic organisms that constitute an interesting reservoir of biologically active metabolites. Moreover, some species of green and red algae present anti-protozoan activity.

Ibandronate metal complexes: solution behavior and antiparasitic activity.

To face the high costs of developing new drugs, researchers in both industry and academy are looking for ways to repurpose old drugs for new uses. In this sense, bisphosphonates that are clinically used for bone diseases have been studied as agents against Trypanosoma cruzi, causative parasite of Chagas disease. In this work, the development of first row transition metal complexes (M = Co, Mn, Ni) with the bisphosphonate ibandronate (iba, Hiba representing the neutral form) is presented.
