Reversal of DNM resistance by combination of suboptimal doses of inhibitors in the MDR L. tropica line. Cell growth of resistant parasites was determined under the conditions described in the legend to Fig. 4, in the presence of different combinations of inhibitors. Data are the means of three independent experiments performed in duplicate, with standard deviations below 15%. pDHS, 8-(1,1-DMA)-DHS; C-3, sesquiterpene C-3; Zos., zosuquidar (LY335979); Ela., elacridar (GF120918).
