Computational modeling demonstrates that the van-der-Waals surfaces of homocubyl amines are similar to that of the neuroprotector Memantine (R). Utilizing readily available precursors we report the preparation of a series of homological cubylamines, namely pentacyclo[6.3.0.0(2,6).0(3,10).0(5,9)]undecyl-4-amine (trishomocubyl-4-amine, 2), pentacyclo[5.3.0.0(2,5). 0(3,9).0(4,8)]decyl-10-amine (bishomocubyl-10-amine, 3), pentacyclo[4.3.0.0(2,5).0(3,8).0(4,7)]nonyl-9-amine (homocubyl-9-amine, 4), and pentacyclo[4.2.0.0(2,5).0(3,8).0(4,7)]octyl-1-amine (cubylamine, 5). The hydrochlorides of amines 2-5 show pronounced affinity for the (+) MK-801 channel binding site, and it seems likely that these compounds would act as very fast voltage-dependent NMDA receptor antagonists.
