Kylo-0603
Kylo-0603 is an orally active thyroid hormone receptor β (THR-β) agonist with an EC50 of 31.07 nM against human targets, and it exhibits much higher selectivity for THR-β than for THR-α. Kylo-0603 enables hepatocyte-targeted delivery via GalNAc modification. Kylo-0603 reduces serum cholesterol and low-density lipoprotein cholesterol levels. Kylo-0603 alleviates hepatic steatosis, inflammatory responses, hepatocyte ballooning, and non-alcoholic steatohepatitis activity scores. Kylo-0603 inhibits the progression of hepatic fibrosis. Kylo-0603 can be used for research on metabolic dysfunction-associated steatohepatitis (MASH).

THR-β 31.07 nM (EC50) |
Kylo-0603 (40-400 μM) acts as a human THR-β-selective agonist with an 8.2-fold greater relative selectivity for THR-β over THR-α, exhibiting EC50 values of 31 nM for THR-β and 124 nM for THR-α in a cell-free TR-FRET assay[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Kylo-0603 (0.1-10 mg/kg; p.o.; once daily; for 8 weeks) dose-dependently improves MASH pathological manifestations, alleviates hepatic fibrosis and steatosis, restores normal thyroid hormone levels, and regulates the expression of genes related to lipid metabolism, inflammation and fibrosis in HFD+CCl4-induced MASH mice[1].
