KL-11743 

KL-11743 is a potent, orally active, and glucose-competitive inhibitor of the class I glucose transporters, with IC₅₀s of 115, 137, 90, and 68 nM for GLUT1, GLUT2, GLUT3, and GLUT4, respectively. KL-11743 specifically blocks glucose metabolism. KL-11743 can synergize with electron transport inhibitors to induce cell death^[1][2][3].

KL-11743 (compound 8) competes with glucose for binding to GLUT1, with IC₅₀s of 33 nM and 268 nM at 0.37 mM and 10 mM glucose, respectively^[1].
KL-11743 (39-10000 nM; 24-72 h) dose-dependently inhibits the growth of HT-1080 cells, with an IC₅₀ of 677 nM^[3].
KL-11743 inhibits the growth of KEAP1-mutant lung cancer cells with more potency compared to KEAP1-WT lung cancer cells^[4].
KL-11743 (0.001-10 μM) induces a rapid increase in the phosphorylation of AMPK and acetyl-coenzyme A carboxylase in HT-1080 cells ^[3].
KL-11743 (2 μM) inhibits glucose uptake in 786-O cells. KL-11743 increases NADP+/NADPH in NCl-H226 cells. KL-11743 induces cell death in SLC7A11-high cancer cell lines (NCl-H226 and UMRC6 cells)^[2].
KL-11743 (0.001-10 μM) inhibits both glucose consumption, lactate secretion, and 2DG transport in HT-1080 fibrosarcoma cells, with IC₅₀s of 228, 234, and 87 nM, respectively, and fully inhibited glycolytic ATP production in oligomycin-treated cells with an IC₅₀ of 127 nM^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

KL-11743 (100 mg/kg; i.p. every two days for 5 weeks) decreases the growth of SLC7A11-high NCI-H226 xenograft tumors and was well-tolerated in vivo^[2].
KL-11743 (30-100 mg/kg; a single p.o.) significantly elevates blood glucose levels and delays glucose clearance in mice challenged with 5 g/kg glucose^[3].
KL-11743 significantly suppresses the growth of KEAP1 KO tumors^[4].
Plasma levels of KL-11743 (100 mg/kg; i.p.) are maintained at inhibitory levels for most of the 24-hour dosing period^[2].
KL-11743 (p.o) exhibits moderate oral between 30% and 15%, and favorable and dose-linear plasma exposure profile reaching concentrations of approximately 20 μM in mice (10-100 mg/kg) and rats (10-300 mg/kg)^[3].
KL-11743 exhibits comparable half-lives ranging between 2.04 and 5.38 h in rats (10 mg/kg for i.v.; 10-300 mg/kg for p.o.), and 1.45-4.75 h in mice (10 mg/kg for i.v. and i.p.; 10-100 mg/kg for p.o.)^[3].
