FIG. 3.

Stage-specific effect of TSA and compounds 9 and 14 against P. falciparum-infected erythrocytes. P. falciparum-infected erythrocytes (Dd2) starting at the ring (A), trophozoite (B), or schizont (C) stage were grown in the presence of 200 nM TSA or 50 and 200 nM compound 9 or 14. Parasitemia was determined by microscopic examination of Giemsa-stained thin blood smears over ∼2 to 4 days (representative experiments are shown). Error bars indicate standard deviations between replicate counts on the same slide.
