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 1revised 5arevised, 5brevised, 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 1revised and biotinylated analogues of 5arevised, 5brevised, and 6, we expect that the conclusions of Yuan et al. with respect to the biological properties of the compounds studied are correct’.
