In vitro trichomonacidal activity of PFUR 4 and 4a-k at 100 µM against Trichomonas vaginalis ATCC 30236 isolate, confirmed by the trypan blue (0.4%) assay after 24 h of exposure: Control (untreated trophozoites), 0.6% DMSO (vehicle for solubilization), MTZ (metronidazole at 100 µM). Viability of 100% in control corresponds to 2.6 × 105 trophozoites/ml. Data are presented as the mean ± standard deviation of at least three independent experiments. Different letters show a significant difference at P < 0.05
