TARGETED PLASMA PROTEIN DEGRADATION
-
, (2021/08/14)
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.

Peptide nucleic acids (PNAs) are DNA analogs that bind with high affinity to DNA and RNA in a sequence-specific manner but have poor cell permeability, limiting use as therapeutic agents. The work described here is motivated by recent reports of efficient gene silencing specifically in hepatocytes by small interfering RNAs conjugated to triantennary N-acetyl galactosamine (GalNAc), the ligand recognized by the asialoglycoprotein receptor (ASGPR). PNAs conjugated to either triantennary GalNAc at the N-terminus (the branched architecture) or monomeric GalNAc moieties anchored at Cγ of three consecutive PNA monomers of N-(2-aminoethyl)glycine (aeg) scaffolds (the sequential architecture) were synthesized on the solid phase. These formed duplexes with complementary DNA and RNA as shown by UV and circular dichroism spectroscopy. The fluorescently labeled analogs of GalNAc-conjugated PNAs were internalized by HepG2 cells that express the ASGPR but were not taken up by HEK-293 cells that lack this receptor. The sequential conjugate was internalized about 13-fold more efficiently than the branched conjugate into HepG2 cells, as demonstrated by confocal microscopy. The results presented here highlight the potential significance of the architecture of GalNAc conjugation for efficient uptake by target liver cells and indicate that GalNAc-conjugated PNAs have possible therapeutic applications.
