Corrigendum: Structural revisions of small molecules reported to cross-link G-quadruplex DNA in vivo reveal a repetitive assignment error in the literature

This article contains inaccuracies in its description of the work presented in reference 1. In the Introduction, " the authors reported a carboxy-substituted derivative of bis-imine 1 which they used in a pull-down study ". should read: " the authors reported a carboxy-substituted derivative of bis-imine 1 as a synthetic intermediate for their further pull-down study ". In the 'Misassignment 2' section, 'They described the use of bis-imine 5 in a pull-down study to prove the existence of G-quadruplex structures in promoter region of oncogenes in vivo'. should read: 'They described the use of bis-imine 5 as a synthetic intermediate for their further pull-down study to prove the existence of G-quadruplex structures in promoter region of oncogenes in vivo. ' In the Conclusions, ' As this structural moiety is present also in the benzimidazoles 1 revised 5a revised , 5b revised , and 6 we expect that the conclusions of Yuan et al. with respect to the biological properties of the compounds studied are correct'. Should read ' As this structural moiety is present also in the benzimidazole 1 revised and biotinylated analogues of 5a revised , 5b revised , and 6, we expect that the conclusions of Yuan et al. with respect to the biological properties of the compounds studied are correct' .
