Abstract

Four novel oxepin-containing pyrimidines, namely oxepinamides D-G (1-4), were isolated from cultures of Aspergillus puniceus F02Z-1744. The structures of 1-4 were elucidated by analyzing their spectroscopic data generated by 1D and 2D NMR and MS methods. The configurations of 1 and 2 were established based on single-crystal X-ray crystallographic analysis. All four compounds 1-4 showed transcriptional activation on Liver X Receptor α (LXRα) with EC 50 values of 10.6, 12.8, 13.6, and 12.1 μM, respectively. Oxepinamides D-G, which are four novel oxepin-containing pyrimidines, were isolated from cultures of Aspergillus puniceus F02Z-1744. All four compounds showed moderate transcriptional activation on LXRα (Liver X Receptor), whereas no effects were observed on FXRα, PPARα, PPARβ, PPARβ, RARα, RXRα, or ERα at concentrations of 30 μM.
