L

arval stage of flatworm, tetrathyridium, has ability of survival and asexual multiplication in a wide range of vertebrate hosts what

indicates a high biochemical and physiological potential for adaptation. We recently developed axenic long-term

in vitro

cultivation

systems of larvae under both hypoxic and aerobic conditions, representing the unique eukaryotic model for pharmacological and

molecular studies. This

in vitro

system allowed us to study the dose- and time-dependent effects of various natural compounds on

multiple biochemical and molecular pathways in larvae. We have focussed on flavonolignans (silybin, dehydrosilybin and silychristin)

prepared from silymarin, the main component of herb Silybum marrianum and two other flavonoids: bergenin and arbutin. Activity

of individual compounds on metabolic activity of larvae, which reflects activity of enzymes of complex I and II in mitochondria, was

dependent on oxygen tension in culture. Flavonolignans also modulated activity of other enzymes like GST, SOD, enzymes involved

in glucose transport, in lipogenesis, cell death and motility, indicating their complex activity on multiple targets in larvae.
