Leishmania (L.) infantum as well as trypomastigote/amastigote forms of Trypanosoma cruzi. The obtained results indicated that gibbilimbol B displayed potential against the tested parasites and low toxicity to mammalian cells, stimulating the preparation of several quite simple synthetic analogues in order to improve its activity and to explore the preliminary structure–activity relationships (SAR) data.
