Relative toxicity of conjugates 1–15 and parent compounds II and III in axenic amastigotes and promastigotes.

<p>Axenic cultures of <i>L. donovani</i> promastigotes and amastigotes were exposed at compound concentration of 1 µg/mL and 2.5 µg/mL, respectively. Thymidine incorporation was measured to monitor cell proliferation. The results show the mean of 2 or 3 independent repeats.
