Fig. 4 — HRMS/MS spectra of protonated metabolites that were shifted relative to BTX-2 by: +H₂(m/z897), leading to 2a (A) and 2b (B); +H₄(m/z899), 3 (C); +O (m/z911), 4a (D), 4b (E), and 4c (F); +H₂O (m/z913), 5b (G), 5c (H), 5d (I), and 5e (J). 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 are scaled to m/z 62–935 for m/z 897 and 899, and m/z 65–950 for m/z 911 and 913.
