Table 1 In vitro anti- T. gondii RH strain activity and selectivity of E. longifolia fractions and clindamycin

From: In vitro Anti-Toxoplasma gondii Activity of Root Extract/Fractions of Eurycoma longifolia Jack

Tested drugs name EC50(μg/ml) Selectivitya
Fractions TAF 355 0.369 63.7
Fractions TAF 401 0.882 17.0
Clindamycin (Positive control) 0.016 656.3
  1. EC50, median effective concentration.
  2. a Ratio of the EC50 value for Vero cells to the EC50 value for Toxoplasma gondii tachyzoites. The EC50 value for Vero cells was used from our previously published data (TAF 35 = 23.50 μg/ml, TAF 401 = 15.00 μg/ml and Clindamycin = 10.5 μg/ml) [20].
