title: Amides of piperidine, morpholine and piperazine substituted 1-phenylethylamines: inhibitors of acylCoA:cholesterol acyltransferase (ACAT) activity in vitro and in vivo.
abstract: Amides of some substituted 1,2-diarylethylamines have been shown to exhibit potent acylCoA:cholesterol acyltransferase (ACAT, EC 2.3.1.26) inhibitory activity in vitro in microsomal ACAT assays but show poor in vivo activity in a cholesterol-fed hamster model. In an effort to design ACAT inhibitors that are potent in both our in vitro and in vivo assays a series of amides of piperidine, morpholine and piperazine substituted 1-phenylethylamines were synthesized. Compounds of this series were found to be very potent inhibitors of ACAT in a microsomal ACAT assay and also exhibited potent activity in a cholesterol-fed hamster model.
