was performed using a nanoAcquity UPLC coupled via electrospray ionization
to a Xevo TQ mass spectrometer (Waters Corporation). Briefly, 1 μL
of each sample was injected directly onto a 150 μm × 100
mm 1.7 μm Acquity BEH130 C18 column (Waters) using a 23 min
gradient of 3–40% MeCN at a flow rate of 1.8 μL/min with
a column temperature of 35 °C. Data were analyzed using Skyline.36 (link)
