Bioorg Med Chem Lett. 2018 Jun 1;28(10):1911-1914. doi: 10.1016/j.bmcl.2018.03.077. Epub 2018 Mar 30.

Abstract

Callyspongiamides A (1) and B (2), two new sterol O-acyltransferase (SOAT) inhibitors, were isolated from the Indonesian marine sponge Callyspongia sp. together with a known congener, dysamide A (3). The structures of 1 and 2 were elucidated to be polychlorine-containing modified dipeptides based on their spectroscopic data. Compounds 1-3 inhibited both of the SOAT isozymes, SOAT1 and SOAT2, in cell-based and enzyme-based assays.

Keywords: Callyspongiamide; Inhibitor; Marine sponge Callyspongia sp.; Polychlorine-containing modified dipeptide; Sterol O-acyltransferase.
