The screening pipeline utilised in this anti-infective study.
A total of 14 compounds were initially screened against S. mansoni schistosomula at a final concentration of 10 μM. Hits were subsequently subjected to dose response titrations with the most effective anti-schistosomula compound (Compound 1) subsequently being used as a template for the preparation of further derivatives (compounds 2–9). Compounds 2–9 were subsequently subjected to dose response titrations against schistosomula and adult worms. The most effective compounds (original compound 1 and analogue 3) were next titrated against juvenile worms. Finally, compounds 1, 3, 5 and 6 were additionally titrated against both Gram+ (S. aureus) and Gram- (E. coli) bacterial exemplars.
