Patent number: 8703799Abstract: Disclosed herein are non-competitive NMDA receptor antagonists having chemical structures similar to that of phencyclidine (PCP). These antagonists contain a polycyclic ring structure in place of the cycloalkyl ring of PCP. The antagonists also differ from PCP in that they include an electron withdrawing group, a hydroxyl group, or an amine group at the para position of the phenyl ring. The antagonists disclosed herein are useful for treating or ameliorating a symptom of ailments associated with over excitation of cells (e.g., neurons) that express NMDA receptors. Examples of ailments that can be treated and for which symptoms can be ameliorated include epilepsy, neurodegenerative disease (e.g., Alzheimer's and Parkinson's diseases), drug addiction, neuropathic pain, and neuronal and glutamate-dependent tumors.Type: GrantFiled: January 31, 2012Date of Patent: April 22, 2014Inventor: Adeboye Adejare

Patent number: 6180707Abstract: The process of this invention can be utilized to stabilize tin-coupled rubbery polymers. This process involves adding a chelating diamine or a metal salt of a cyclic alcohol to the rubbery polymer after the tin coupling has been carried out. This invention more specifically discloses a process for improving the stability of a tin-coupled rubbery polymer which comprises adding a metal salt of a cyclic alcohol to the tin-coupled rubbery polymer subsequent to the time at which the tin-coupled rubbery polymer is coupled. The use of metal salts of cyclic alcohols does not lead to recycle stream contamination because they do not co-distill with hexane or form compounds during steam-stripping which co-distill with hexane. In other words, the boiling points of these metal salts of cyclic alcohols are very high, so they do not co-distill with hexane and contaminate recycle streams. Additionally, metal salts of cyclic alcohols are considered to be environmentally safe.Type: GrantFiled: December 1, 1999Date of Patent: January 30, 2001Assignee: The Goodyear Tire & Rubber CompanyInventors: Wen-Liang Hsu, Adel Farhan Halasa
