Patents by Inventor Yu-Chang John Wang

Yu-Chang John Wang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20090258826
    Abstract: This invention provides novel peptides that function in vivo as agonists of the VPAC2 receptor. These insulin secretagogue polypeptides are shown to lower blood glucose in vivo more than controls upon glucose challenge. The polypeptides of this invention are also stable in formulation and have long half-lives. The peptides of the present invention provide a new therapy for patients with decreased endogenous insulin secretion, in particular type 2 diabetics. In particular, the invention is a polypeptide selected from a specific group of VPAC2-related polypeptides, or functional equivalents thereof. The invention is also directed to a method of treating a metabolic disease in a mammal comprising administering a therapeutically effective amount of the insulin secretagogue peptides to said mammal. Also disclosed are methods of making the peptides, both recombinant and synthetic.

  • Patent number: 6331309
    Abstract: Compositions and methods are disclosed for the controlled release delivery of polypeptide growth factors. The compositions of the invention are hydrogels which comprise: a polypeptide growth factor having at least one region of positive charge; a physiologically acceptable water-miscible anionic polymer; a physiologically acceptable non-ionic polymeric viscosity controlling agent; and water.

  • Patent number: 6187330
    Abstract: Compositions and devices for the controlled release delivery of a peptide or protein drug are produced by dispersing a glassy matrix phase comprising the peptide or protein drug and a thermoprotectant in a bioerodable, biocompatible polymer at a temperature that is below the glass transition temperature of the glassy matrix phase and above the melting point of the polymer. The method and composition of the invention may be employed for the local delivery of angiogenic amounts of basic fibroblast growth factor or vascular endothelial growth factor.
