Malaria remains one of the main health threats in the developing world, with staggering social and economic costs. Resistance to artemisins, the main pharmacological tool currently available against malaria, has been widely reported. Borrelidin, a natural compound that inhibits threonyl-tRNA synthetase, has long been studied for its antibacterial and antiparasitic properties, but undesirable toxic effects prevented its further clinical development. Here we present a group of borrelidin derivatives that retain their ability to inhibit Plasmodium threonyl-tRNA synthetase but not its human homolog. Furthermore, we demonstrate, for the first time to our knowledge, that these compounds are capable of effectively clearing a Plasmodium infection in animals, curing malaria with a potency equivalent to reference drugs such as chloroquine.
