In the original article, there was a mistake in Figure 1 as published. The structures of compounds 1–4 were drawn wrong. The corrected Figure 1 appears below.
Figure 1
Additionally, in section Materials and Methods, the first sentence of the “Cytotoxicity Assay” section should be revised as “Five tested human tumor cell lines, human leukemia (HL-60), hepatocellular carcinoma (SMMC-7721), lung cancer (A-549), breast adenocarcinoma (MCF-7), and colon carcinoma (SW-480), were purchased from ATCC (Manassas, VA, USA).”
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
