Mass spectra were recorded with a Thermo Scientific Vanquish Horizon ultrahigh pressure liquid chromatograph coupled to an electrospray ionization Q Exactive Plus high-resolution mass spectrometer (UHPLC-HRMS) with a resolving power of up to 1.4 x 10 5 (at m/z 200). The separation was performed on a reverse phase column (Phenomenex Luna Omega Polar C18, 150
