KPLH1130 is a pyruvate dehydrogenase kinase (PDK) inhibitor. KPLH1130 potently inhibits M1 macrophage polarization by reducing the expression of pro-inflammatory cytokines, decreasing the levels of M1 phenotype markers (HIF-1alpha, iNOS) and nitric oxide (NO) production. KPLH1130 prevents the reduction of mitochondrial oxygen consumption rate (OCR) induced by inflammatory stimuli (LPS ((HY-D1056) + IFN-gamma) in various macrophage types. KPLH1130 improves glucose tolerance in HFD-fed mice. KPLH1130 can be used for the study of obesity-associated metabolic disorders and other inflammatory conditions[1].
