Molecular design of multitarget neuroprotectors 3. Synthesis and bioactivity of tetrahydrocarbazole-aminoadamantane conjugates

A synthetic approach to the design of new multitarget neuroprotectors consisting in combination of the tetrahydrocarbazole and aminoadamantane pharmacophore fragments through a 2-hydroxypropylene spacer upon the reaction of 9-oxiranylmethyl-2,3,4,9-tetrahydro-1H-carbazoles and aminoadamantanes, which affords 1-(adamantan-1-ylamino)-3-(1,2,3,4-tetra-hydrocarbazol-9-yl)-propan-2-ols, is proposed. The effect of the synthesized compounds on the neuronal NMDA receptors and the functional characteristics of rat liver mitochondria was studied.
