PG - 752-63 LID - 10.1038/labinvest.2011.11 [doi] AB - Hepatic fibrosis is the result of chronic liver injuries underlined by diverse etiologies. The massive accumulation of extracellular matrix (ECM) proteins during fibrogenesis leads to structural distortion and functional disruption of the liver. There is currently no effective standard treatment for liver fibrosis. We previously identified a class of imidazolium salts (IMSs) with anti-fibrotic properties in a cell-based screen. In this report, we investigated the anti-fibrotic efficacy and mechanisms of a small IMS, 1,3-diisopropylimidazolium tetrafluoroborate (DPIM), in a hepatic fibrosis model induced by bile duct ligation (BDL) in mice. The orally available DPIM was administered to BDL mice via drinking water at three concentrations (0.5, 0.75, and 1 g/l) for 4 weeks. We observed a significant reduction in inflammation and collagen deposition in the liver, which could be mediated by a reduction in the expression of monocyte chemoattractant protein-1 (MCP-1) and by an enhancement in the matrix metalloproteinase-mediated ECM remodeling. The current findings highlight the importance for simultaneously targeting multiple pathways to more effectively attenuate and resolve liver fibrosis and warrant further studies on this compound in additional models of hepatic fibrosis.
