Abstract
Correction for ‘Cationic pillar[6]arene/ATP host–guest recognition: selectivity, inhibition of ATP hydrolysis, and application in multidrug resistance treatment’ by Guocan Yu et al., Chem. Sci., 2016, 7, 4073–4078, https://doi.org/10.1039/C6SC00531D.
It has come to the authors’ attention that an error requiring correction exists in Fig. 4a. The image was inadvertently duplicated during the final typesetting process, resulting in the unintended repetition of visual data. This occurred as a result of a technical oversight in figure assembly and did not reflect any issue with the underlying experimental data.
Fig. 4. (a) Fluorescence images of the MCF-7/ADR cells stained with calcein-AM incubated without/with FA-PEG-b-PAA (250 μM), PIC micelles containing different amount of WP6. (b) Fluorescence intensity changes of the culture in the presence of FA-PEG-b-PAA or PIC micelles containing different amounts of WP6. (c) Cytotoxicity of DOX·HCl (25 μM), FA-PEG-b-PAA, PIC micelles, and DOX·HCl (25 μM) loaded PIC micelles with different concentrations of WP6 against MCF-7/ADR cells. Schematic illustration of the preparation of PIC micelles and possible mechanism to inhibit the efflux pump by forming a host–guest complex WP6⊃ATP in the cell.
The correct figure is displayed below.
