Background:

FH535 is a small molecule inhibitor of Wnt/B-catenin with IC50 values of 15.4μM, 10.9μM, 9.3μM, respectively in LCSC, Huh7, PLC cell lines [1].

FH535 can inhibit the growth of colon, lung, and hepatocellular carcinoma line but not normal fibroblasts. It makes FH535 potentially be a promising therapeutic approach for cancer cells. It is reported that FH535 has ability to inhibit growth, migration, and invasion of TN breast cancer cell lines (MDA-MB-231 and HCC38) without affecting adhesive abilities of cells to type I collagen [2].

FH535 is also an inhibitor of peroxisome proliferator–activated receptor (PPAR). It plays a role as a dual PPARγ and PPARδ antagonist that is able to inhibit GRIP1 and β-catenin recruitment [3].
