Description: F5446 is a SUV39H1 inhibitor. F5446 has an EC50 of 0.496 μmol/L for SUV39H1 enzymatic activity. H3K9me3 was enriched in the promoters of GZMB, PRF1, FASLG, and IFNG in quiescent T cells. F5446 inhibited H3K9me3, thereby upregulating expression of these effectors in tumor-infiltrating CTLs and suppressing colon carcinoma growth in a CD8+ CTL-dependent manner in vivo. Our data indicate that SUV39H1 represses CTL effector gene expression and, in doing so, confers colon cancer immune escape.

More Info: F5446 decreased H3K9me3 deposition at the FAS promoter, increased Fas expression, and increased CRC cell sensitivity to FasL-induced apoptosis in vitro. Furthermore, inhibition of SUV39H1 altered the expression of genes with known functions in DNA replication and cell cycle in the metastatic colon carcinoma cells, which is associated with cell cycle arrest at S phase in the metastatic human colon carcinoma cells, resulting in tumor cell apoptosis and growth inhibition in a concentration-dependent manner in vitro. Moreover, F5446 increased 5-FU-resistant human CRC sensitivity to both 5-FU- and FasL-induced apoptosis and inhibited tumor cell growth in vitro. More importantly, F5446 suppressed human colon tumor xenograft growth in vivo.
