  • Publication number: 20230233689
    Abstract: 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, Fc?RI, FcRN, Transferrin or Macrophage Scavenger receptor.

  • Publication number: 20230228113
    Abstract: A swimming pool wall, and method for forming same, including a plurality of layers of reinforced composite material. Each layer includes a thermoplastic resin and a plurality of elongate glass strands of reinforcing material. A first set of the plurality of layers has the strands running in a first direction, and a second set of the plurality of layers has the strands running in a second direction. The first direction is offset in angle from the second direction, and the first and second set of layers are fused together to form a unitary composite wall. The pool wall permits the use of a composite material which provides sufficient strength and resists degradation. The wall structure may be a plurality of interconnected panels both arcuate and arcuate and planar in shape to determine the overall shape of the composite wall enclosing an area where water or ice is retained.

  • Publication number: 20230159611
    Abstract: In one embodiment, the invention provides a chimeric antigen receptor (CAR) T cell which is conjugated to a bi-functional molecule which is specific for both an extracellular binding domain of the chimeric antigen receptor (CAR) T cell and prostate-specific membrane antigen (PSMA). The chimeric antigen receptor (CAR) T cell contains a T cell signaling domain and the extracellular binding domain of the chimeric antigen receptor (CAR) T cell is not specific for prostate-specific membrane antigen (PSMA). Compositions and methods of treatment using these CAR T cells are also disclosed.

  • Publication number: 20230090282
    Abstract: 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.

  • Publication number: 20230087994
    Abstract: 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.

  • Publication number: 20220111060
    Abstract: The present invention relates to compounds which function as antibody mimetic compounds. These compounds are bifuinctional/multifuinctional compounds which contain at least one cancer cell binding moiety which selectively binds to prostate specific membrane antigen (PSMA) and a FC receptor binding moiety which modulates an FC immune receptor, preferably a Fc?RI receptor. Compounds according to the present invention bind selectively to cancer cells which upregulate PSMA and through that interaction, place the Fc receptor binding moiety of the compound in proximity to a Fc receptor, preferably a Fc?RI receptor, which can modulate (preferably, upregulate) a humoral response in a patient to cancer cells. Through this biological action of the compounds according to the present invention, cancer cells, including metastatic cancer cells, especially prostate cancer cells can be immune regulated, resulting in the favorable therapy of cancer in a patient.

  • Publication number: 20220089579
    Abstract: The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as ARM-HI's, function through orthogonal pathways, by inhibiting the gp120-CD4 interaction, and by recruiting anti-DNP antibodies to gp120-expressing cells, thereby preventing cell infection and spread of HIV. It has been shown that ARM-HI's bind to gp120 and gp-120 expressing cells competitively with CD4, thereby decreasing viral infectivity as shown by an MT-2 cell assay, the binding leading to formation of a ternary complex by recruiting anti-DNP antibodies to bind thereto, the antibodies present in the ternary complex promoting the complement-dependent destruction of the gp120-expressing cells. Compounds and methods are described herein.

  • Publication number: 20210284988
    Abstract: The present invention relates to chimeric (preferably, bifunctional) compounds, compositions comprising those compounds and methods of treating cancer in a patient or subject, especially including metastatic cancer where cancer cells exhibit ovrexpression (heightened expression) of cell surface urokinase-type plasminogen activator receptor (urokinase receptor) compared to normal (non-cancerous) cells. The compounds preferably covalently bind to the urokinase receptor and recruit native antibodies of the patient or subject where the antibodies can selectively degrade and/or deactivate targeted cancer cells through antibody-dependent cellular phagocytosis and/or antibody-dependent cellular cytotoxicity (ADCC) against a large number and variety of cancers, thus providing cancer cell death and/or an inhibition of growth, elaboration and/or metastasis of the cancer, including remission and cure of the patient's cancer.
