Asperlin Inhibits LPS-Evoked Foam Cell Formation and Prevents Atherosclerosis in ApoE-/- Mice.

ABSTRACT: Asperlin is a marine-derived natural product with antifungal and anti-inflammatory activities in vitro. In the present study, we isolated asperlin from a marine Aspergillus versicolor LZD4403 fungus and investigated its anti-atherosclerotic effects in vitro and in vivo. Asperlin significantly inhibited lipopolysaccharides (LPS)- but not oxidated low-density lipoprotein (oxLDL)-evoked foam cell formation and promoted cholesterol efflux in RAW264.7 macrophages. Supplementation with asperlin also suppressed LPS-elicited production of pro-inflammatory factors in RAW264.7 macrophages, decreased the expression levels of iNOS, IL-1β and TNFα, and increased the expression of IL-10 and IL-4, indicating a remarkable shift in M1/M2 macrophages polarization. In vivo experiments in high-fat diet (HFD)-
