Biological Activity
NFS1 inhibitor Compound 53 is the first potent, selective inhibitor of human cysteine desulfurase (NFS1) with IC50 of 40.5 uM and Ki of 6.4 uM.
Compound 53 shows no significant inhibitory effects on two other PLP-dependent enzymes, human cystathionine-β-synthase (CBS) and cystathionine-γ-lyase (CSE) at 100 uM.
Compound 53 inhibited the proliferation of lung cancer (A549) cells with IC50 of 16.3 uM.
Compound 53 inhibits the activities of ACO and SDH in cells by disrupting Fe-S cluster biosynthesis through the direct inhibition of NFS1 activity, significantly increases the cellular iron content, similar to the effect of the well-recognized ferroptosis inducer, Erastin.
Compound 53 elevates the iron content but does not affect the ROS levels in A549 cells.
Compound 53 synergizes with 2-AAPA to induce ferroptosis.
