| Abstract: | Parallel in vitro tests, assessing the inhibition of schizont maturation, were conducted with 31 fresh isolates of Plasmodium falciparum from Thailand, using artemisinin, doxycycline, and combinations of both. The activities of artemisinin and doxycycline are obviously not correlated. Both compounds showed consistent synergism at 50% effective concentration (EC(50)), EC(90), and EC(99) levels. |
