Abstract: Various embodiments provide a homo-bivalent linker compound comprising identical functional groups at either end, methods of making such linker compounds, and methods of using the linker compounds.

Abstract: Defined multi-conjugate oligonucleotides can have predetermined sizes and compositions. For example, in various embodiment, defined multi-conjugate oligonucleotides can have advantageous properties, for example in the form of defined multi-conjugate siRNA (i.e., including two, three or more siRNA) having enhanced intracellular delivery and/or multi-gene silencing effects. In various embodiment, the defined multi-conjugate oligonucleotides can be synthesized via new synthetic intermediates and methods. The defined multi-conjugate oligonucleotides can be used, for example, in reducing gene expression, biological research, treating or preventing medical conditions, or to produce new or altered phenotypes in cells or organisms.

Abstract: The present disclosure relates to multimeric oligonucleotides having monomeric subunits joined by linkers and methods of administering multimeric oligonucleotides to a subject. The multimeric oligonucleotides have a molecular weight and/or size configured to increase in vivo activity of one or more subunits within the multimeric oligonucleotide relative to in vivo activity of the same subunit when administered in monomeric form. The present disclosure also relates to such multimeric oligonucleotides and methods of synthesizing such multimeric oligonucleotides.

Abstract: A multi-conjugate comprising two or more covalently linked biological subunits, wherein at least two of the subunits are terminally located targeting ligands. A pharmaceutical composition comprising a pharmaceutically acceptable excipient and a therapeutic agent that is the multi-conjugate is also disclosed. The multi-conjugate may be administered to a subject for providing treatment or prophylaxis against a disease or other medical condition.

Abstract: Linker compounds, methods of making them, and methods of using them as linking agents for oligonucleotides and other chemical and biological substances are described. Embodiments of linker compounds are configured or selected to exhibit higher stability to cleavage by serum nucleases relative to intracellular nucleases, enabling enhanced control of longevity and hence bioavailability to a target cell of the chemical and biological substances linked together by such linker compounds when administered to a subject.

Abstract: The present disclosure relates to methods of administering, subcutaneously, to a subject, multimeric oligonucleotides having monomeric subunits joined by covalent linkers. The multimeric oligonucleotides have a molecular weight and/or size configured to increase in vivo activity of one or more subunits within the multimeric oligonucleotide relative to in vivo activity of the same subunit when administered in monomeric form of at least about 45 kD and other characteristics, such that their clearance due to glomerular filtration is reduced. The present disclosure also relates to such multimeric oligonucleotides and methods of synthesizing such multimeric oligonucleotides.
