The present invention provides compounds, compositions thereof, and methods of using the same for the targeted degradation of proteins, and the treatment of target protein-mediated disorders.

The present disclosure provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In another aspect, the present disclosure provides bifunctional compounds that can be used to promote or enhance degradation of certain autoantibodies. In certain embodiments, treatment or management of a disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein or the autoantibody in the subject. Thus, in certain embodiments, administration of a compound of the disclosure to the subject removes or reduces the circulation concentration of the circulating protein or the autoantibody, thus treating, ameliorating, or preventing the disease and/or disorder. In certain embodiments, the circulating protein is TNF.

The present disclosure provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of certain circulating proteins. In certain embodiments, the circulating protein mediates a disease and/or disorder in a subject, and treatment or management of the disease and/or disorder requires degradation, removal, or reduction in concentration of the circulating protein in the subject. Thus, in certain embodiments, administration of a compound of the disclosure to the subject removes or reduces the circulation concentration of the circulating protein, thus treating, ameliorating, or preventing the disease and/or disorder.

Compositions or an assembly of a series of biomimetic compounds include chemical structures that mimic or structurally resemble a nucleic acid base pair. Complexes of nanotubes and agents are useful to deliver agents into the cells or bodily tissues of individuals for therapeutic and diagnostic purposes. Exemplary compounds include those of Formula (I), (III), (V) or (VII), or of Formula (II), (IV), (VI) or (VIII). ##STR00001##

The description relates to cereblon E3 ligase binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

The present invention relates to bifunctional Proteolysis Targeting Chimeric ligands (Protac compounds) comprising a ligase modulator/binder and a molecule that binds to a protein target of interest, and methods of treating various diseases and conditions with the Protac compounds, including diseases associated with androgen receptors.

A pharmaceutical composition containing a mixed polymeric micelle and a drug enclosed in the micelle, in which the mixed polymeric micelle, 1 to 1000 nm in size, includes an amphiphilic block copolymer and a lipopolymer. Also disclosed are preparation of the pharmaceutical composition and use thereof for treating cancer.

Compositions and methods for the treatment of viral infections include conjugates containing inhibitors of viral RSV F protein (e.g., Presatovir, MDT 637, JNJ 179, or an analog thereof) linked to an Fc monomer, an Fc domain, and Fc-binding peptide, an albumin protein, or albumin-binding peptide. In particular, conjugates can be used in the treatment of viral infections (e.g., RSV infections).

Bifunctional compounds, which find utility as modulators of androgen receptor (AR), are described herein. In particular, the bifunctional compounds of the present disclosure contain on one end a moiety that binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds AR, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The bifunctional compounds of the present disclosure exhibit a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aberrant regulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

The present disclosure is directed to bifunctional small molecules which contain a circulating protein binding moiety (CPBM) linked through a linker group to a cellular receptor binding moiety (CRBM) which is a membrane receptor of degrading cell such as a hepatocyte or other degrading cell. In certain embodiments, the (CRBM) is a moiety which binds to asialoglycoprotein receptor (an asialoglycoprotein receptor binding moiety, or ASGPRBM) of a hepatocyte. In additional embodiments, the (CRBM) is a moiety which binds to a receptor of other cells which can degrade proteins, such as a LRP1, LDLR, FcγRI, FcRN, Transferrin or Macrophage Scavenger receptor.
