CA3121410C — Drug containing liver targeting specific ligand and thyroid hormone receptor agonist

USPTO Abstract

Provided is a drug containing a liver targeting specific ligand and a thyroid hormone receptor agonist in its structure, which is a new drug structure formed by linking the liver targeting specific ligand with the thyroid hormone receptor agonist through a branch chain, a linker and a joining chain. Thyroid Hormone Receptors (TRs) are divided into two subtypes, TR-a and TR-ß, wherein, TR-ß is mainly expressed in liver, and TR-a is mainly expressed in heart, nervous system, etc. In certain embodiments, it is envisaged that the provided drug has the action of liver targeting, can specifically bring the thyroid hormone receptor agonist into liver, without entering heart and other issues, and may thereby avoide side effects caused by the action of the thyroid hormone receptor agonist on other issues, and maintain its therapeutic efficacy in the treatment of lipid metabolism disorders and related complications.
