Materials and Methods of Treating Viral Infection with Amphiphilic Block Copolymers
Abstract: Provided is a method of contacting a subject, cell, or tissue with an amphiphilic block copolymer to treat a viral infection. The resulting effect can be treating a disease caused by a virus, inhibiting viral replication, inhibiting an unfolded protein response of a virus, preventing death of tissue infected by a virus, or promoting cell repair and recovery to increase survival of cells infected by a virus. The hydrophobic block of the amphiphilic block copolymer binds to an exposed hydrophobic domain of the virus. Further provided is an amphiphilic block copolymer comprising three or more hydrophobic substituents or an alkylene spacer on a hydrophobic block of the copolymer.
Methods and Compositions for Treating Mammalian Nerve Tissue Injuries
Abstract: To achieve, an in vivo repair of injured mammalian nerve tissue, an effective amount of a biomembrane fusion agent is administered to the injured nerve tissue. The application of the biomembrane fusion agent may be performed by directly contacting the agent with the nerve tissue at the site of the injury.
Alternatively, the biomembrane fusion agent is delivered to the site of the injury through the blood supply after administration of the biomembrane fusion agent to the patient. The administration is preferably by parenteral administration including intravascular, intramuscular, subcutaneous, or intraperitoneal injection of an effective quantity of the biomembrane fusion agent so that an effective amount is delivered to the site of the nerve tissue injury.
Compositions and Methods for Refolding of Denatured Proteins
Compounds and methods for refolding of proteins in an aqueous solution. In particular, biocompatible multiblock copolymer surfactants such as poloxamers, meroxapols, poloxamines, or polyols are used to catalyze proper refolding without changing the protein composition, and restore the protein to its native conformation and native biological function. The methods can be practiced both in vivo and in vitro. The biocompatible multiblock copolymer surfactants can be used for renaturation of recombinantly expressed proteins, and for renaturation of proteins that are unfolded due to heat, irradiation, mechanical shearing, electrical shock, frostbite, chemical stress, and other abiotic or biotic stresses.
