Atherosclerosis and its clinical sequelae still represent the primary cause of death in Western societies. During the past 25 years, a novel drug class to treat dyslipidemia, a main risk factor for coronary artery disease, emerged: liver- and thyroid hormone receptor isoform β- selective analogs. The present review will discuss the recent patents applied for sobetirome (GC-1), which set the course for the establishment of a novel approach to lower plasma cholesterol and triglycerides. We will focus on the major mechanisms conferring sobetirome lipid-lowering properties, including the induction of hepatic LDL receptor, the promotion of the so-called reverse cholesterol transport, and finally the induction of bile acid production and biliary sterol secretion. In summary, thyromimetics such as sobetirome may represent a useful treatment for combined hyperlipidemia, which is associated with a major cardiovascular risk.
