Acanthoic acid
Acanthoic acid (NP1302) is an orally active pimarane-type diterpenoid. Acanthoic acid is isolated from the root bark of Araliaceae family plant Eleutherococcus senticosus (Siberian ginseng). Acanthoic acid activates LXR and FXR. Acanthoic acid activates the AMPK-LKB1, SIRT1, and p38 MAPK signaling pathways and increases the phosphorylation level of ACC. Acanthoic acid downregulates the expression of SREBP-1, CYP2E1, HIF-1α, and PPARγ, and upregulates the expression of PPARα. Acanthoic acid induces Apoptosis by activating Caspase-3, promoting PARP cleavage, and downregulating Bcl-xL. Acanthoic acid exhibits antioxidant, anti-fibrotic, and hepatoprotective effects. It reduces lipid accumulation and lipogenesis. Acanthoic acid is used in studies on non-alcoholic fatty liver disease, alcoholic liver disease, acute promyelocytic leukemia, and Acetaminophen-induced hepatotoxicity.
