LC/MS/MS product ion spectra of indapamide and its metabolites by human
liver microsomes or CYP3A4, obtained by CID of the [M-H]–
ions corresponding to m/z 364, indapamide (A);
m/z 380, M1 (B); m/z 394, M2 (C);
m/z 378, M3 (D); m/z 378, M4 (E); and
m/z 362, M5 (F). The putative assignments of characteristic
fragment ions are shown.
