Phenylethanolamines

WebPhenylethylamines are usually competitive inhibitors and the isomers with the relative configuration as in (2S)-amphetamine (1) and (2S)-2-aminotetralin (3) are better inhibitors than their enantiomers. Phenylethanolamines are usually substrates of PNMT and the enzyme prefers the 1R isomers, such as (1R)-phenylethanolamine (5), in this class. WebJul 13, 2005 · We have recently shown that the β-adrenoceptor ligands CGP 12177, bupranolol, and SR 59230A (aryloxypropanolamines), but not BRL 37344 and CL 316243 (phenylethanolamines), exhibit significant affinity for α1-adrenoceptors and that CGP 12177 displays partial agonist properties at α-adrenoceptors in rat pulmonary artery.
