Diglycosyl diselenides alter redox homeostasis and glucose consumption of infective African trypanosomes

International Journal for Parasitology: Drugs and Drug Resistance, 2017
With the aim to develop compounds able to target multiple metabolic pathways and, thus, to lower the chances of drug resistance, we investigated the anti-trypanosomal activity and selectivity of a series of symmetric diglycosyl diselenides and disulfides.
