Patents by Inventor Byoung-Joo Gwag

Byoung-Joo Gwag 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: 20100323995
    Abstract: The present invention provides compositions and methods for prevention and prophylaxis of neurological diseases accompanied by neuronal death. The invention includes synthesis of 5-benzylamino salicylic acid (BAS) and its derivatives. BAS and its derivatives protect cortical neurons from toxic insults by N-methyl-D-aspartate, Zn2+, and reactive oxygen species. Thus, the present invention provides compositions and methods for treating stroke, traumatic brain and spinal cord injury, epilepsy, and neurodegenerative diseases that are accompanied by severe neuronal loss via excitotoxicity, Zn2+ neurotoxicity, and free radical neurotoxicity.

  • Patent number: 7608585
    Abstract: Disclosed is a method for inhibition of necrosis induced by neurotrophin, and more specifically a method for inhibition of necrosis by administrating oxidative stress inhibitor and a method for simultaneous inhibition of necrosis and apoptosis by administrating oxidative stress inhibitor and neurotrophin. The oxidative stress inhibitor of the present invention can inhibit nerve cell necrosis induced by neurotrophin. Moreover, it can be used for protecting nerve cell damage connected with alzheimer disease, parkinson's disease, degenerating cerebropathia and promoting regeneration of the nerve cells by administrating oxidative stress inhibitor and neurotrophin.
