Uskutočnila sa konformačná analýza bázických štruktúr piatich agonistov I1-receptorov (klonidín,moxonidín,rilmenidín,fentolamín a fencyklidín)a jedného antagonistu I1-receptorov (idazoxan)metódou MM2.Štruktúra stabilných konformácií sa optimalizovala metódou AM1.Vizualizovalasa podobnosť stabilných konformácií jednotlivých látok.Ďalej sa vypočítala protónová afinitaa lipofilita,ktoré môžu výrazne vplývať na afinitu k receptoru a účinok látok.Je zrejmé,že všetkyštudované liečivá,až na fencyklidín,sú schopné zaberať rovnaký priestor a dôležitú úlohu pre afinituštudovaných liečiv k I1-receptorom môže mať nízka lipofilita (logP =1 až 2).
