  • Publication number: 20180319848
    Abstract: The present invention provides modified cupredoxin derived peptides with pharmacologic activity that have improved pharmacokinetic properties, and methods to use them to treat mammals suffering from various conditions related to the pharmacologic activities. Modifications of the cupredoxin derived peptides include amino acid sequence variants and structural derivations that increase the plasma half-life of the peptide, increase the specific activity of the pharmacologic activity, decrease immunogenicity, and decrease the biotransformation of the peptides. The modified cupredoxin derived peptides can be used in methods to treat mammals for cancer, conditions elated to inappropriate angiogenesis, viral and bacterial infections, and specifically HIV and malaria, conditions related to ephrin signaling, and to deliver cargo compounds, including diagnostic compounds, to cancer cells.

  • Patent number: 10117905
    Abstract: The present invention relates to compositions comprising peptides that may be variants, derivatives and structural equivalents of cupredoxins that inhibit the development of premalignant lesions in mammalian cells, tissues and animals. Specifically, these compositions may comprise azurin from Pseudomonas aeruginosa, and/or the 50-77 residue region of azurin (p28). The present invention further relates to compositions that may comprise cupredoxin(s), and/or variants, derivatives or structural equivalents of cupredoxins, that retain the ability to inhibit the development of premalignant lesions in mammalian cells, tissues or animals. These compositions may be peptides or pharmaceutical compositions, among others. The compositions of the invention may be used to prevent the development of premalignant lesions in mammalian cells, tissues and animals, and thus prevent cancer.

  • Publication number: 20180250258
    Abstract: Liquid nutritional compositions that include functional ingredients such as beta-hydroxy-beta-methylbutyrate, docosahexaenoic acid, and lutein are disclosed. The nutritional compositions are useful to promote at least one of physical performance (e.g., body composition, muscle mass, muscle strength) and cognitive function (e.g., focus, attention, alertness, executive function) in an individual. The functional ingredients are incorporated into the nutritional composition in such a way that they do not adversely affect the desirable properties of the nutritional composition such as, for example, nutritional value, stability, solubility, taste, and mouthfeel.

  • Patent number: 9969781
    Abstract: The present invention relates to compositions comprising CpG rich DNA from Pseudomonas aeruginosa. The compositions optionally comprise a cupredoxin. The present invention includes specific CpG DNAs from Pseudomonas aeruginosa that are useful for treating cancer and other conditions in patients. These compositions are optionally in a pharmaceutically acceptable carrier and also optionally comprise a cupredoxin. The present invention further relates to methods to express proteins near cancer cells. These methods may be used to express therapeutic or diagnostic proteins near cancer cells in a patient suffering from cancer or other conditions, and can also be used for diagnosing cancer in a patient. This method uses the gene for azurin from P. aeruginosa as an expression system for azurin or heterologous proteins in P. aeruginosa or heterologous cells.
