“…First, using non-targeted lipidomics comprising ultrahigh pressure liquid chromatography accurate-mass quadrupole time-of-flight mass spectrometry with electrospray ionization (UHPLC-ESI-QTOF-MS/MS) [ 18 ], and imaging of neutral lipids, we explored the ability of lorlatinib to alter the lipidome of hepatoma tissue-derived Huh-7 and HepG2 cells [ 19 , 20 , 21 , 22 , 23 , 24 ], which were employed as substitutes for primary hepatocytes. Second, we investigated whether silibinin––a flavonolignan that functions as a hepatoprotectant in patients with acute and chronic liver injury [ 25 , 26 , 27 , 28 , 29 , 30 ]––might prevent the lipid-modifying activity of lorlatinib in hepatocytes. To predict potentially relevant drug–drug interactions if silibinin were used to clinically manage lorlatinib-associated hyperlipidemia, we finally explored the capacity of silibinin to interact with and block CYP3A4 activity in comparison with currently employed statins.…”
