Resumo |
The effect of the active sulphoxide metabolite of the anthelmintic triclabendazole (TCBZ-SX, 15-50 mu g ml(-1)) on the incorporation of radioactively labelled [C-14] leucine by adult Fasciola hepatica tissue slices was measured by liquid scintillation counting. In addition, the ability of the microfilament-disrupting drug, cytochalasin B, and the microtubule-disrupting drug, tubulozole-C, to inhibit protein synthesis, was assessed by similar methods and compared with TCBZ-SX. The established protein synthesis inhibitors, cycloheximide and actinomycin D were used as positive controls. All the drugs showed a significant inhibition of protein synthesis, albeit to different extents; however, TCBZ-SX was the most potent, with no significant difference between its effect and that of cycloheximide or actinomycin D. Moreover, the concentration of TCBZ-SX, above 15 mu g ml(-1), had little further influence on incorporation of [C-14] leucine. This investigation demonstrates the inhibitory effect of TCBZ-SX, cytochalasin B and tubulozole-C on protein synthesis in F. hepatica and confirms the qualitative observations made in several previous ultrastructural studies. |
