Heterocyclic ring scaffolds as small-molecule cholesterol absorption inhibitors

Article abstract of DOI:10.1039/b510100j

Enantio- and diastereoselective syntheses of a substituted oxazolidinone, isoxazoline and pyrazoline as β-lactam surrogates are described. The substituted heterocycles were designed to incorporate side chains closely resembling those found in the β-lactam cholesterol absorption inhibitor ezetimibe (1). Additionally, the in vitro inhibitory efficacy of the novel compounds as cholesterol absorption inhibitors is reported using a brush border membrane vesicle assay. The Royal Society of Chemistry 2005.
