Bioactivity | FEN1-IN-3 (Compound 4) is a human flap endonuclease-1 (hFEN1) inhibitor. FEN1-IN-3 stabilizes hFEN1 with an EC50 of 6.8 μM[1]. | ||||||||||||
Invitro | FEN1 inhibition selectively impairs proliferation of colon cancer cells deficient in Cdc4 and Mre11a, both frequently mutated in colorectal cancers. FEN1 has also emerged as a potential chemosensitizing target due to its role in LP-BER since it is critical for repair of Methyl methanesulfonate-induced alkylation damage, and its knockdown or inhibition increases sensitivity to Temozolomide in glioblastoma and colorectal cancer cell lines[1]. | ||||||||||||
