Conformational Study of Drugs with Effect on I1-Imidazoline Receptors
- Katedra farmaceutickej chémie Farmaceutickej fakulty Univerzity Komenského, Bratislava
Conformational analysis of five I1-receptor agonists in the neutral form (clonidine,moxonidine,rilmenidine,phentolamine,and phencyclidine)and one antagonist of I1-receptors (idazoxane)wascarried out by means of the MM2 method.Structures of stable conformations of individualcompounds were fully optimised.Degree of similarity of stable conformations was visualized.Theproton affinities and lipophilicities of title compounds were also computed.It is obvious that allstudied drugs except phencyclidine are able to occupy the same space.An important role for affinity of studied drugs towards I1-receptors can be played by their different hydrophobicity (logP =1 to 2).
