β-Lactams have recently been identified as potent, highly efficacious cholesterol absorption inhibitors (CAIs). The discovery, SAR, and asymmetric synthesis of this class of hypolipidemic agents are described. Metabolism studies of the first clinical candidate, Sch 48461, led to the identification of a more potent second generation clinical candidate, Sch 58235 (ezetimibe) incorporating key structural elements of the active metabolites. A summary of preclinical and early clinical studies of ezetimibe as monotherapy and in combination with statins is also presented. Efforts to identify a pharmacophore model has led to the development of conformationally constrained analogs and analogs with conformational biases based on intramolecular hydrogen bonding possibilities. Finally, mechanism of action studies have led to the development of many biochemical tools for the investigation and identification of novel proteins involved in cholesterol uptake.

Keywords: actam Cholesterol, ezetimibe, hypolipidemic agents, pharmacophore model, intramolecular hydrogen bonding
