A bio-inspired enantioselective small-molecule artificial receptor for β adrenergic agonists and antagonists and its application for enantioselective extraction.

Administration of enantiomerically pure β-adrenergic agonists and antagonists increases their activity and reduces side effects. We report here a small-molecule artificial receptor (SMAR) that, by mimicking the β-adrenergic receptor, is able to enantioselectively extract commercial β-adrenergic interacting drugs. The selectivity is justified according to DFT calculations and X-ray diffraction experiments.
