Synthesis and biological evaluation of memantine nitrates as a potential treatment for neurodegenerative diseases

Author affiliations

Abstract

A series of memantine nitrate derivatives, as dual functional compounds with neuroprotective and vasodilatory activity for neurodegenerative diseases, was designed and synthesized. These compounds combined the memantine skeleton and a nitrate moiety, and thus inhibited the N-methyl-D-aspartic acid receptor and released NO in the central nervous system. The biological evaluation results revealed that the new memantine nitrates were effective in protecting neurons against glutamate-induced injury in vitro. Moreover, memantine nitrates dilated aortic rings against phenylephrine-induced contraction. The structure–activity relationships of neuroprotection and vasodilation were both analyzed. In further studies, compound MN-05 significantly protected cortical neurons by inhibiting Ca2+ influx, reducing free radical production and maintaining the mitochondrial membrane potential. Further research on MN-05 is warranted.
