Abstract

Human flap Endonuclease 1 (hFEN1) is instrumental in DNA replication and repair. It is able to cleave the 5' single-stranded protrusion (also known as 5' FLAP) resulting from strand displacement reactions. In LIGHT of its crucial functions, hFEN1 is now deemed as a nontrivial target in the DNA damage response system for Anticancer drug development. Herein, we report that myricetin and some natural Flavonoids are able to inhibit hFEN1. Structure-activity relationship, inhibitory mechanisms, molecular docking, and Cancer cell-based assays have been performed. Our original findings expand the activity of Flavonoids and may pave the way for flavonoid-assisted targeted Cancer therapy.
