  • Publication number: 20210196676
    Abstract: The present disclosure relates to the use of the sequiterpene lactones and Helenalin (H. tox) or its derivatives to treat viral infection and virally induced lesions, such as warts or wart-associated skin or mucosal lesion. A topical application, optionally using a skin covering such as gauze, a bandage, or a patch, can substantially reduce and even eliminate persistent, recurrent and/or treatment-resistant warts.

  • Patent number: 9770504
    Abstract: The present invention provides for methods of identifying peptoid mimetics that will mimic B cell epitopes when delivered as vaccine compositions. One aspects of the invention is the use of monoclonal antibody that is broadly protective to select the mimetics, thereby identifying an epitope from a pathogen or other disease-causing agent that will be common among most or all variants of that pathogen or agent.

  • Patent number: 8658168
    Abstract: This invention discloses monoclonal antibodies (MAbs) which have little or no signaling activity as monomers become potent anti-tumor agents when they are converted into homoconjugates. The homoconjugates exert anti-growth activity by signaling G0/G1 arrest or apoptosis, depending upon which cell surface molecule they bind. This activity is specific and does not require an Fc portion. These conjugates are potent, anti-tumor agents.

  • Patent number: 8323665
    Abstract: The present invention provides methods to produce toxoid vaccines, such as ricin A chain vaccines, with reduced ability to promote vascular leak syndrome (VLS) and catalytic toxicity associated with various proteinaceous toxins, such as ribosome inactivating proteins. The invention also provides toxoids which have been mutated to lack amino acid sequences which induce VLS and toxic catalytic activity.

  • Patent number: 7829668
    Abstract: The present invention provides methods to produce immunotoxins (ITs) and cytokines with a reduced ability to promote vascular leak syndrome (VLS). The invention also provides ITs and cytokines which have been mutated to lack amino acid sequences which induce VLS. Also disclosed are methods for producing peptides that inhibit the induction of VLS by ITs and cytokines. Also disclosed are peptides comprising the (x)D(y) sequence to promote the extravasation of other molecules. Toxins mutated in the (x)D(y) motif or active site residues are disclosed for used in vaccines.

  • Patent number: 7668603
    Abstract: A composition of microscopic devices utilizable in a medical diagnostic or therapeutic procedure. Each microscopic device includes a nanostructure provided with a ligand for effectively coupling the nanostructure to a predetermined chemical or molecular site. A medical method in part comprises inserting the medical devices into a patient, attaching the nanostructures via the respective ligands to instances of a predetermined type of target structure inside the patient, and thereafter activating the nanostructures to perform a preselected medical diagnostic or therapeutic function.

  • Patent number: 5767072
    Abstract: Disclosed are methods and compositions for the treatment of HIV infections through the specific elimination of cells which express HIV env determinants such as gp120. The compositions of the invention include toxin conjugates composed of a CD4 derived gp120 binding ligand conjugated to a toxin A chain moiety such as ricin A chain or deglycosylated ricin A chain. Where a therapeutic composition is desired, the conjugates are formed by means of a cross linker which includes a disulfide bond. Disulfide linkages are not crucial where non-therapeutic uses, such as antibody generation, is intended. In preferred aspects of the invention, conjugates incorporating shorter CD4 peptides, such as those incorporating amino acids 41-57 or 41-84 of CD4, are disclosed.
