To investigate the effect of compound 1 on gametogenesis, stage V Pfrh3− gametocytes were induced with and without compound 1.
(A) Light micrographs of XA-stimulated gametocytes in the presence (left panel) or absence (right panel) of 2 μM compound 1. The size bar indicates 5 μm.
(B) Increasing concentrations of compound 1 were added with XA (or without XA, Con), and cells were scored as either round or crescent-shaped, and plotted as percentage rounded up. Results are based on duplicate counts from a representative experiment, and error bars indicate mean ± SEM. The results of this experiment have been reproduced on more than ten occasions.
(C) The number of centres of exflagellation per 10,000 gametocytes was scored. Results are based on duplicate counts from a representative experiment, and error bars indicate mean ± SEM.
