  • Publication number: 20240148885
    Abstract: The present disclosure provides, in one aspect, bifunctional compounds that can be used to promote or enhance degradation of an extracellular or cell surface protein. In certain embodiments, the extracellular protein mediates a disease and/or disorder in a subject, and treatment or management of the disease and/or disorder requires degradation, removal, and/or reduction in concentration of the protein in the subject. In some embodiments, the disease and/or disorder is a neurological disease and/or disorder. Thus, in certain embodiments, administration of a compound of the disclosure to the subject removes or reduces the amount of the extracellular or cell surface protein in the brain, thus treating, ameliorating, or preventing the disease and/or disorder.

  • Publication number: 20240083859
    Abstract: The present invention is directed to bi-functional compounds which find use as pharmaceutical agents in the treatment of disease states and/or conditions which are mediated through macrophage migration inhibitory factor (MIF) or immunoglubin G (IgG). The present invention is also directed to pharmaceutical compositions which comprise these bi-functional compounds as well as methods for treating disease states and/or conditions which are mediated through MIF/IgG or where MIF/IgG is a contributing factor to the development and perpetuation of diseases and/or conditions, especially including autoimmune diseases and cancer, among others. The purpose of the present invention is to provide a molecular strategy to lower plasma MIF/IgG level in patients with autoimmune diseases or certain types of cancers.

  • Patent number: 11920172
    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 overexpression (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.

  • Patent number: 11858917
    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: 20230355920
    Abstract: Systems and methods for increasing hypnotizability in accordance with embodiments of the invention are illustrated. One embodiment includes a method of treating a recipient using hypnotherapy, including applying neurostimulation to a recipient's brain such that functional connectivity between an anterior cingulate cortex (ACC) and a dorsolateral prefrontal cortex (DLPFC) of the recipient's brain is increased, and activity in the ACC is decreased, and applying hypnotherapy in order to treat a condition of the recipient. In a further embodiment, the condition is selected from the group consisting of depression, anxiety, phobia, pain, stress, disordered eating, sleep disorders, posttraumatic stress, and addiction.

  • 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.
