  • Patent number: 11046733
    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.

  • Patent number: 11007165
    Abstract: Liquid nutritional compositions include functional ingredients such as beta-hydroxy-beta-methylbutyrate, docosahexaenoic acid, and lutein. 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: 10675326
    Abstract: The present invention discloses methods and materials for killing and/or inhibiting the growth of a cancer cell via preferential entry of a cytotoxic compound. Preferential entry of the cytotoxic compound is accomplished by the use of protein transduction domains derived from cupredoxins, including the p18 and p28 truncations of azurin.

  • Patent number: 10590177
    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.
