General description

A 2-phenylpyridazin-3(2H)-one based non-copper chelater that selectively inhibits the activity of Superoxide dismutase 1 (Cu/Zn-SOD) (IC₅₀ = 1.07 µM). Cells over-expressing SOD1 show reduced sensitivity to LCS-1. Shown to preferably inhibit the growth of a variety of human lung adenocarinoma cell lines with EGFR and KRAS mutations (IC₅₀ = 200 nM). Prevents serum-induced activation of the ERK and PI 3-kinase/AKT signaling thereby affecting cell growth and survival. Apparent half-life of this compound is reported to be 6.6 min in human liver microsomes.
