Patent number: 8871269Abstract: The methods disclosed herein are of use for the production of controlled release compositions. In particular, the methods provide the contacting of an organic phase containing a bioactive agent and a polymer with an aqueous phase containing an organic ion to create controlled release compositions containing bioactive agents. The present invention also includes controlled release compositions including a polymer, an organic ion and a bioactive agent. The present invention also includes methods of using such controlled release compositions. The usefulness of the present invention is that the methods result in the production of controlled release compositions containing bioactive agent capable of administration in a concentrated low-dose form, having low burst and reduced production of degraded bioactive agent.Type: GrantFiled: July 15, 2004Date of Patent: October 28, 2014Assignee: Evonik CorporationInventor: Gary P. Cook

Patent number: 8865206Abstract: Dermal delivery is best suited for the various skin diseases or disorders. However, the stratum corneum limits the permeation of number of suitable pharmaceutical agents for dermal delivery. Certain embodiments of the present invention include surface modified multilayered nanostructures. The modification was completed by using fatty acids enabling delivery of a significant amount of one or more pharmaceutical agent(s) into deeper layers of the epidermis and dermis to treat skin diseases or disorders. Each active pharmaceutical agent can be encapsulated into the separate layers of the nanostructures.Type: GrantFiled: December 10, 2013Date of Patent: October 21, 2014Assignee: Florida A&M UniversityInventors: Mandip Sachdeva, Punit Shah

Publication number: 20140308203Abstract: Provided herein are methods for delivering a molecule in situ to a cell and for treating a cancer via the in situ delivery. The methods comprise contacting or administering to the cell, as two separate components, a morpholino oligonucleotide comprising a targeting moiety followed by a single wall nanotube construct comprising second morpholino oligonucleotides complementary to the first morpholino oligonucleotides and one or both of a therapeutic or diagnostic payload molecule linked to the single wall nanotube construct. Upon self-assembly of a single wall nanotube complex via hybridization of the first morpholino and second complementary morpholino oligonucleotides at the cell, the payload molecule is delivered. Also provided is the two component self-assembly single wall nanotube system and the single wall nanotube construct comprising the second component.Type: ApplicationFiled: June 27, 2014Publication date: October 16, 2014Inventors: David A. Scheinberg, Michael R. McDevitt, Carlos H. Villa, J. Justin Mulvey

Patent number: 8859004Abstract: The present invention discloses the pH-sensitive nanoparticles composed of pH-sensitive polymer, hydrophobic material, internal stabilizer, external stabilizer content and insulin drug. The present invention also includes a method for preparation of pH-sensitive nanoparticles, in particular, a multiple emulsions solvent evaporation method. The pH-sensitive nanoparticles of the present invention show good pH-sensitive property with 100-300 nanometer particle size. Significant decrease in blood glucose level is observed in streptozotocin (STZ)-induced diabetic rats and the bioavailability of insulin is more than 10% after oral administration of the insulin-loaded pH-sensitive nanoparticles.Type: GrantFiled: July 30, 2012Date of Patent: October 14, 2014Assignee: Nano and Advanced Materials Institute LimitedInventors: Lijuan Zhang, Li Ling, Li Ying Zhou, Zhi Min Wu, Xin Dong Guo, Wei Jiang, Qian Luo, Yu Qian
