| Description |
PDK4-IN-1 is an anthraquinone derivative and a potent and orally active pyruvate dehydrogenase kinase 4 (PDK4) inhibitor with an IC50 value of 84 nM. PDK4-IN-1 potently represses cellular transformation and cellular proliferation and induces apoptosis. PDK4-IN-1 has antidiabetic, anticancer and anti-allergic activity[1].

PDK4-IN-1 (Compound 8c; 50 μM; 0-72 hours; HCT116 and RKO cells) treatment significantly impedes the proliferation of human colon cancer cell lines, HCT116 and RKO. The colony formation efficiency in HCT116 and RKO cells Is significantly reduced after treatment of PDK4-IN-1[1]. PDK4-IN-1 (Compound 8c; 10-50 μM; 24 hours; HCT116 and RKO cells) treatment dose-dependently increased apoptosis[1]. PDK4-IN-1 (Compound 8c; 10 μM; 24 hours; HEK293T cells) treatment inhibits phosphorylation of Ser232, Ser293, and Ser300 of PDHE1α[1]. 10 μM of PDK4-IN-1 (Compound 8c) significantly increases p-Akt in AML12 cells[1]. PDK4-IN-1 (compound 8c)-induced phosphorylation of p53 on serine 15 is a dose-dependent response in both HCT116 and RKO cells. PDK4-IN-1 decreases the expression of BCL-xL and increases the expression of BAX. Cleavage of PARP1 and caspase 3 are increased by PDK4-IN-1[1]. Cell Viability Assay[1] Cell Line: HCT116 and RKO cells Concentration: 50 μM Incubation Time: 0 hour, 24 hours, 48 hours, 72hours Result: Significantly impeded the proliferation of human colon cancer cell lines, HCT116 and RKO. Apoptosis Analysis[1] Cell Line: HCT116 and RKO cells Concentration: 10 μM, 25 μM, 50 μM Incubation Time: 24 hours Result: Dose-dependently increased apoptosis. Western Blot Analysis[1] Cell Line: HEK293T human embryonic kidney cells Concentration: 10 μM Incubation Time: 24 hours Result: Inhibited phosphorylation of Ser232, Ser293, and Ser300 of PDHE1α.

PDK4-IN-1 (Compound 8c; 100 mg/kg; oral administration; daily; for 1 week; C57BL/6J mice) treatment significantly improves glucose tolerance[1]. Pre-incubation with PDK4-IN-1 (compound 8c) dose-dependently inhibits the release of β-hexosaminidase from IgE/antigen-activated BMMCs, showing that the absorbance values are 0.26, 0.20, and 0.126 in IgE/Ag, 10 μM, and 20 μM PDK4-IN-1-treated BMMCs[1]. The pharmacokinetic (PK) profiles of PDK4-IN-1 (compound 8c) are evaluated in rat. PDK4-IN-1 shows good bioavailability (64%), long half-life (>7 h), and moderate clearance (CL of 0.69) in rats[1]. Animal Model: C57BL/6J mice (8-week old) fed with high-fat diet[1] Dosage: 100 mg/kg Administration: Oral administration; daily; for 1 week Result: Significantly improved glucose tolerance.
