The predicted Log P values for AFB1, AFB2, AFG1 and AFG2 were extracted from the Hazardous Substances Data Bank (HSDB), a database of the National Library of Medicine's TOXNET system (http://toxnet.nlm.nih.gov) on 28 August, 2019. The predicted Log P value for AFM1 and AFM2 were extracted from the Metabolomics Innovation Centre (https://www.metabolomicscentre.ca) and had been calculated with ALOGPS (http://www.vcclab.org/lab/alogps/).
