WQQ-345
WQQ-345 is an orally active BCAT1 inhibitor with an IC50 values of 10.8 mM. WQQ-345 reduces cellular α-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.

Biological Activity
WQQ-345 (2.5-5 mM; 7-10 days) dose-dependently inhibits colony formation of 67R NSCLC cells[1].
WQQ-345 (5-10 mM; 3 days) dose-dependently reduces intracellular α-KG levels, upregulates H3K27me3 protein expression, and downregulates PFKP and LDHA protein expression in 67R NSCLC cells after 3 days of treatment at 5 mM or 10 mM[1].
WQQ-345 (5 mM; 3 days) impairs glycolytic activity (lowered ECAR) in 67R NSCLC cells[1].

Cell Line:ASK120067-resistant NCI-H1975 (67R) NSCLC cells
-
Concentration:2.5, 5 mM
-
Incubation Time:7-10 days
-
Result:Dose-dependently reduced colony formation of 67R cells, with significant inhibition observed at both 2.5 mM and 5 mM.
Resulted in stronger growth inhibition when co-treated with 1 μM ASK120067 (HY-138751) than either monotherapy.
Lost growth-inhibitory effects in 67R cells with BCAT1 knockdown, confirming on-target activity.

Animal Model:BALB/c nude (4-week-old) subcutaneously injected with 67R cells[1]
-
Dosage:80; 120 mg/kg
-
Administration:p.o.; twice daily; 43 days
-
Result:Achieved robust tumor regression at 120 mg/kg, with significantly smaller tumor volumes compared to vehicle control by day 43.
Increased H3K27me3 protein expression significantly in tumors treated with 120 mg/kg relative to vehicle control tumors.
Decreased protein levels of glycolytic enzymes PFKP, LDHA, and PKM1/2 significantly in tumors treated with 120 mg/kg relative to vehicle control tumors.
