WQQ-345 is an orally active BCAT1 inhibitor with an IC50 values of 10.8 mM. WQQ-345 reduces cellular alpha-KG levels, upregulating H3K27me3 expression, decreasing glycolytic enzyme expression, and impairing glycolysis activity. WQQ-345 reduces colony formation, suppresses growth of BCAT1-high TKI-resistant lung cancer cells. WQQ-345 exerts in vitro and in vivo antitumor activity. WQQ-345 can be used for the research of TKI-resistant non-small cell lung cancer and TKI-resistant lung cancer[1][2].
