F5446 (Compound 1) is a selective small-molecule inhibitor of the histone methyltransferase SUV39H1. By reducing H3K9 trimethylation (H3K9me3) at the Fas promoter, F5446 upregulates Fas expression and enhances the sensitivity of colorectal carcinoma cells to Fas ligand (FasL)-induced apoptosis in vitro. In vivo, F5446 effectively suppresses the growth of human colorectal tumor xenografts, highlighting its potential as an epigenetic therapeutic agent in cancer treatment.
