The present invention is directed to the bifunctional compounds and the use of such bifunctional compounds to lower plasma levels of extracellular target molecules by lysosomal degradation. Such bifunctional compounds have a cell surface receptor ligand covalently linked to a ligand that is capable of binding to an extracellular target molecule (such as a ligand for a growth factor, a cytokine, a chemokine, a hormone, a neurotransmitter, a capsid, a soluble receptor, an extracellular secreted protein, an antibody, a lipoprotein, an exosome, a virus, a cell, or a plasma membrane protein), where the cell surface receptor is associated with receptor mediated endocytosis, including asialoglycoprotein receptor (ASGPR) mediated lysosomal degradation and mannose-6-phosphate (M6PR) mediated lysosomal degradation. Pharmaceutical compositions comprising such bifunctional compounds and methods of treating a disease or disorder mediated by an extracellular molecule using such bifunctional compounds are also provided herein.
