Table 1. In Vitro Antitrypanosomal Activity (EC50, μM)a against Wild Type and Resistant Strains of T. b. brucei and Cytotoxicity against HEK Cells (CC50, μM).
Mean of three experiments ± SEM.
T. b. brucei s427 trypomastigotes.
T. b. brucei knockout strain10 lacking a functional P2-transporter and resistant to diminazene aceturate.
Resistance factor compared to WT.
The B48 strain11 is a mutant derived from the TbAT1-KO strain with a nonfunctional high affinity pentamidine transporter (HAPT). This strain is resistant to diminazene, pentamidine, and melaminophenyl arsenicals.
Human endothelial kidney cells.
Selectivity index = [CC50/EC50 (T.b.b.WT)].
Not determined.
