Detailed SAR examination and DIStance COmparison (DISCO) computation were used for identification and superposition of common structural features of 2,3-benzodiazepines with high affinity to an allosteric AMPA binding site. Two similar 4-point models were identified; both contained 2 donor sites, a donor atom and a hydrophobic centre. At one of the donor sites a characteristic difference between the two models was observed.
