Quantumchemical parameters (electronegativity and hardness) basedQSAR study of -Carboline derivatives was made with the help of PM3 calculations on CAChe software. The observed required biological activity values of -Carboline were taken fromliterature. The study has shown that, there is inverse relationship between reported biological activity and electronegativity of the -carboline derivatives, and no relationship with absolute hardness. Thus, electronegativity can use as important reactive parameter in search of receptor-specific ligands active for interaction with the BzR/ GABAA.
