For example, Orlistat inhibits FABP1 activity to enhance immunotherapy efficacy in HCC[18], BMS309403 targets FABP4 to inhibit ovarian cancer metastasis and enhance chemosensitivity[29], and SBFI-26 induces ferroptosis in liver cancer cells by inhibiting FABP5[99]. Here, FABP5 is linked to hepatocellular carcinoma.
