Novel cleft-type cyclophanes, 4,4'-bis[N-5-dimethylaminoaphthalene-sulfonylaminoethyl)-N-(1,4,7,10-tetraazacyclododecane-1-ylacetyl)-2-aminoethoxy]diphenylmethane octahydrochloride (1a, DNCn) and 4,4'-bis[N-(p-toluene-sulfonylaminoethyl)-N-(1,4,7,10-tetraazacyclododencane-1-ylacetyl-2-aminoethody]diphenylmethane octahydrochloride (1b, TsDCN) having an effective role as N-methyl-D-aspartate (NMDA) receptor antagonist were synthesized. Neuroprotective effects of cleft-type cyclophanes, DNCn (1a) and TsDCn (1b) against cell damage caused by NMDA were measured in cultured rat hippocampal neurons. DNCn (1a) and TsDCn (1b) reduced the neurotoxicity and acted as open channel blocker for NMDA receptor.
