Fig. 3.

Time courses of [³H]neurotransmitter release induced by the substituted cathinones 3-F MCAT and 4-MEC, the aminoindane MDAI, and the substituted amphetamine 4-FA. hDAT (A), hSERT (B), and hNET (C) cells. Data are representative experiments with a subset of concentrations shown for clarity. Data are normalized to percentage release of [³H]neurotransmitter remaining in cells at each time point. The last three buffer fractions prior to addition of drug and the 11 fractions in the presence of drug are shown.
