a Bar graph showing changes in the mitochondrial membrane potential (ΔΨm) of L. amazonensis and T. cruzi after 24 h of incubation with the IC90 of compounds 1–3 compared to the negative control (DMSO). Differences between the values were assessed using one-way analysis of variance. Data are presented as the mean ± standard deviation (SD). Lowercase letters a–c or uppercase letters A–C indicate that means within compounds with different letters are significantly different (P < 0.05). b Images (×100) are representative of the parasites observed in the performed experiments using the EVOS FL Cell Imaging System
