We investigated 14 compounds causing the NMDA receptor blockage. These polypharmacophoric compounds are conjugates of carbazole, tetrahydrocarbazole and 1-aminoadamantane derivatives. As a measure of biological activity of the compound tested, the IC50 (μM) value, reflecting 50% inhibition of [H3] MK-801 binding to the NMDA receptor, was used. The regression model with satisfactory statistical characteristics was obtained as a result of the QSAR modeling based on the Gaussian process.
