HRMS/MS spectra for the protonated metabolites that were shifted +H₂O₂(relative to BTX-2) withm/z929, 8 (A); +CH₆O metabolites, also withm/z929, 9 (B); and +CH₄O₂metabolites withm/z943, 11a (C), 11b (D), and 11c (E). Data were obtained from samples collected after 60 min incubation of BTX-2 (5 μM, v/v, after dilution in the assay) with L. campechanus (RSN1) or human (HLM) liver microsomes. The m/z ranges (x-axes) are scaled to m/z 65–965 and 65–980 for m/z 929 and 943 metabolites, respectively.
