  • Patent number: 7871641
    Abstract: The instant invention is drawn to a hepatocyte targeted composition comprising a mixture of free glargine insulin and glargine insulin associated with a water insoluble target molecule complex, wherein the complex comprises multiple linked individual units and a supra-molecular lipid construct matrix. Glargine insulin is present within the complex in at least one form wherein the glargine insulin has a positive charge which interacts with a negative charge on the complex. The invention also includes methods for the manufacture of the composition and methods of managing blood glucose levels in individuals with Type I and Type II diabetes.

  • Publication number: 20090087479
    Abstract: The present invention is embodied by a composition capable of chaperoning a typically non-orally available therapeutic or diagnostic agent through the environment of the digestive tract such that the therapetucic or diagnostic agent is bioavailable. The composition may or may not be targeted to specific cellular receptors, such as hepatocytes. Therapeutic agents include, but are not limited to, insulin, calcitonin, serotonin, and other proteins. Targeting is accomplished with biotin or metal based targeting agents.

  • Patent number: 5690956
    Abstract: Strong reducing chemicals are required by prior art to break disulfide bonds of hair structure in alkaline media. The disulfide bonds are responsible for holding the hair in set condition.This disclosure teaches a new means for breaking the disulfide bonds by use of Tris-(2-carboxyethyl) phosphine (TCEP) in a mildly acid solution.The essence of the specification is the breaking of disulfide bonds in an acid environment.
