We report a new series of naphthoquinone derivatives as potent ACAT inhibitors, which were obtained through structural variations of previously disclosed lead 1. Several analogs represented by 3i–l, 4k–m, 6a–n, 7a, and 7i demonstrated potent human macrophage ACAT inhibitory activity by a cell-based reporter assay with human HepG2 cell lines. In particular, compounds 4l and 6j emerged as highly potent inhibitors, exhibiting significantly high ...
