Table 1. EC50 of Prolonged Treatment of LU102 and PR709A in P. falciparum and HFFa.
treatment time (h) | P. falciparum EC50 (μM) | HFF EC50 (μM) | selectivity (HFF/Pf) | |
---|---|---|---|---|
LU102 | 24 | 0.252 ± 0.006 | 11.47 ± 0.033 | 46 |
72 | 0.170 ± 0.004 | 5.12 ± 0.12 | 30 | |
PR709A | 24 | 0.50 ± 0.02 | 245 ± 13 | 490 |
72 | 0.29 ± 0.01 | 165 ± 3 | 569 |
24 and 72 h treatment of ring stage parasites are shown. For 24 h treatment, cells are treated, washed, and placed in new media for a further 48 h of growth. EC50s are expressed as mean ± standard deviation. Selectivity is determined as the ratio of EC50 in HFF over EC50 in P. falciparum.
