Synthesis and Biological Evaluation of a Series of Liver-Selective Phosphonic Acid Thyroid Hormone Receptor Agonists and Their Prodrugs
摘要:
Phosphonic acid (PA) thyroid hormone receptor (TR) agonists were synthesized to exploit the poor distribution of PA-based drugs to extrahepatic tissues and thereby to improve the therapeutic index. Nine PAs showed excellent TR binding affinities (TR beta(1), K-i < 10 nM), and most of them demonstrated significant cholesterol lowering effects in a cholesterol-fed rat (CFR) model. Unlike the corresponding carboxylic acid analogue and T-3, PA 22c demonstrated liver-selective effects by inducing maximal mitochondrial glycerol-3-phosphate dehydrogenase activity in rat liver while having no effect in the heart. Because of the low oral bioavailability of PA 22c, a series of prodrugs was synthesized and screened for oral efficacy in the CFR assay. The liver-activated cyclic 1-(3-chlorophenyl)-1,3-propanyl prodrug (MB07811) showed potent lipid lowering activity in the CFR (ED50 0.4 mg/kg, po) and good oral bioavailability (40%, rat) and was selected for development for the treatment of hypercholesterolemia.
The present invention relates to compounds of phosphonic acid-containing T3 mimetics and monoesters thereof, stereoisomers, pharmaceutically acceptable salts, co-crystals, and prodrugs thereof and pharmaceutically acceptable salts and co-crystals of the prodrugs, as well as their preparation and uses for preventing and/or treating metabolic diseases such as obesity, NASH, hypercholesterolemia and hyperlipidemia, as well as associated conditions such as atherosclerosis, coronary heart disease, impaired glucose tolerance, metabolic syndrome x and diabetes.

The present invention is directed toward the use of thyromimetic compounds that are thyroid receptor ligands, pharmaceutically acceptable salts thereof, and to prodrugs of these compounds for preventing, treating, or ameliorating fatty liver diseases such as steatosis, non-alcoholic fatty liver disease, and non-alcoholic steatohepatitis.
