Received: 25 January 2013; in revised type: 9 April 2013 / Accepted: 9 April 2013 / Published: 12 AprilAbstract: Many novel norcamphor derivatives have been created and synthesized as uncompetitive NMDA receptor antagonists at the phencyclidine (PCP) binding web site.PMID:27641997 Such compounds have possible as ligands for understanding and possibly the therapy of quite a few neurodegenerative issues and also other glutamate-dependent disorders. We examined the toxic effects on the compounds as compared with memantine, an NMDA receptor antagonist that may be FDA approved for treatment of Alzheimer’s illness, by testing these compounds on two cell lines: MDCK (to mimic blood brain barrier) and N2a (a neuronal cell line). The compounds showed toxicity profiles equivalent to these of memantine i.e., dose dependence above one hundred M and IC50 values above 150 M for every single cell line. It truly is recognized that the serum level of memantine under therapeutic conditions in patients is about 1 M, indicting these compounds could have acceptable therapeutic indexes. 2-Phenyl-N-(two(piperidin-1-yl) ethyl)bicyclo[2.two.1]heptan-2-amine (5a) was discovered to possess acceptable toxicity profiles in each cell lines. Interestingly, this was the compound identified as a superb lead in our prior research based on binding and anticonvulsant (MES) activity studies. It has hence emerged as a great lead compound for further studies.Pharmaceuticals 2013, 6 Keywords: NMDA receptor antagonist; neurodegeneration; cytotoxicity; MDCK and N2a cells1. Introduction Glutamate is amongst the principal excitatory neurotransmitters in the mammalian central nervous program (CNS). A major function of glutamate will be the handle of ion flow at excitatory synapses. 3 ionotropic receptors for glutamate happen to be identified depending on ligand selectivity: 2-amino-3-(3hydroxy-5-methyl-isoxazol-4-yl)propanoic acid (AMPA), N-methyl-D-aspartatic acid (NMDA), and kainic acid (Figure 1). NMDA receptors are fast-acting, ligand-gated cation channels using a higher permeability for Ca2+ which are activated by the binding of both L-glutamate as well as the co-agonist, glycine [1].
