Results of HPLC-HRMS analysis and postulated molecular structures for MZ233. a Excerpt of extracted ion chromatogram (EIC) for m/z 233.15 from HPLC-HRMS analysis of the supernatant of TABA3 at 24 h. Information about peaks with abundance > 10⁶ is listed in the table. No corresponding peaks were observed in 5D-tHMG1. RT retention time, MF molecular formula. b Possible structures for the compound with m/z 233.1539 at 5.9 min (named MZ233). Structures are based on the assumption that the compound originates from the ABA backbone and has the molecular formula C₁₅H₂₀O₂
