The outcome of the study revealed that 2,3-bis(4-chlorophenylthio), 2- phenylthio-, 2-amino-, 2-amino-3-chloro-1,4-
naphthoquinones showed a high level of activity against all three fungi [20, 21].
This lack of activity was most likely caused by the high cytotoxicity of
naphthoquinones present in the extracts (Brandao et al.

In summary, we may observe that while the composition of the secretions of the three species is similar in constituting mixtures of ketones and
naphthoquinones, there are significant differences both qualitative and quantitative.

Chemically, phenols and benzoquinones predominate within laniatorid secretions, while acyclic components and, at least in Phalangium opilio Linnaeus 1758, also

Naphthoquinones are compounds present in various families of plants; their molecular structures endow them with redox properties which confer activity in various biological oxidative processes.

Several compounds isolated from plants, such as terpenoids, sterols, flavonoids, alkaloids, phenolics and
naphthoquinones have been studied to evaluate their effects on Leishmania spp.
