Abstract

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 inhibitory potencies with IC₅₀ values of 0.44 μM and 0.6 μM, respectively. Moreover, compound 4l significantly reduced the accumulation of cellular cholesterol in HepG2 cell lines.
