Abstract

Structural understanding of subtype specific ligand-binding pocket variations and interactions of ligand with receptor may facilitate design of novel selective drugs. To gain insights into the subtype selectivity of β-blockers we performed flexible molecular docking study to analyze the interaction mode of cardioselective phenoxyaminopropanol blocker into the β1 and β2-adrenergic receptor. The binding site analysis reveals a strong identity between important amino acid residues and interactions with ligand in orthosteric catecholamine- binding pocket. The differences in the binding mode of selective ligand have been identified in the extracellular region of receptor subtypes.
