Abstract
Correction for ‘Analysis of the quantitative structure–activity relationship of glutathione-derived peptides based on different free radical scavenging systems’ by Wenzhen Liao et al., Med. Chem. Commun., 2016, DOI: 10.1039/c6md00006a.
The authors regret that some corrections had not been made to the final manuscript. Please find the required corrections listed below:
In section 2.7 Statistical analysis, the final sentence ‘The MAE based criteria......the QSAR model.24’ should be replaced by: ‘The MAE based criteria were used for the training set using cross-validated leave-one-out (LOO) predictions for additional validation of the QSAR models.24,58 The software tool to perform the MAE based test was downloaded from the website: http://teqip.jdvu.ac.in/QSAR_Tools/.’
The above revised sentence includes a new reference: 58. K. Roy, R. N. Das, P. Ambure and R. B. Aher, Chemom. Intell. Lab. Syst., 2016, 152, 18–33.
In section 3.5.1 Predictive capability of the models, the sentence ‘Therefore, external validation......high predictive power.’ should be replaced by: ‘However, in the absence of sufficient number of data points for external validation, the MAE based criteria were applied for cross-validation, and the results proved that the QSAR model for ORAC database exhibited a high predictive power.’
In Table 4 the title of the final column ‘External validation test (MAE)’ should be replaced by: ’MAE based criteria’.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
