Three natural products have been assembled to obtain a new antimalarial hit. (+)-Usnic acid was used as scaffold to design and synthesize new products, that were tested on asexual development for P. falciparum and P. berghei. Among them, the ester of (+)-usnic acid-4-aminobutyric acid 14 with dihydroartemisinin shows considerable in vivo antimalarial activity against P. berghei in mice, similar to the synthetic drug artesunate. Compound 14 behaves as a delivery system for dihydroartemisinin and combine the effects of the endoperoxide with the redox properties of the phenolic portions of (+)-usnic acid.
