Kukoamine B (KB), derived from the traditional Chinese herb cortex Lycii, exerts anti-inflammatory effects due to its potent affinity with lipopolysaccharide (LPS) and CpG DNA; however, little is known regarding whether the in vivo administration of KB can effectively inhibit inflammation in septic mice. The present study thus aimed to investigate the inhibitory effects of KB on the inflammatory response in the livers of LPS-induced septic mice. KB treatment in the LPS-induced septic mice significantly decreased the plasma level of LPS. In addition, KB protected against liver injury, as confirmed by improved histology and decreased aminotransferase levels in the serum. Further experiments revealed that KB attenuated liver myeloperoxidase activity and reduced the expression of vascular cell adhesion molecule-1 and intercellular adhesion molecule-1. These effects were accompanied by decreases in the levels of tumor necrosis factor ? and interleukin-1? in the liver tissue. In parallel, the activity of nuclear factor-?-gene binding (NF-?B) in the livers of LPS-induced septic mice was markedly inhibited with KB treatment. In combination, these results demonstrate that KB inhibits inflammation in septic mice by reducing the concentrations of plasma LPS, decreasing leukocyte sequestration and interfering with NF-?B activation, and, therefore, suppressing the pro-adhesive phenotype of endothelial cells.

A major cause of cerebral ischemia is overactivation of the N-methyl-D-aspartate receptors (NMDARs). Therefore, NMDAR antagonists are needed for the treatment of cerebral ischemia. In our research, KuB protected the SH-SY5Y cells against NMDA-induced injury, apoptosis, LDH release and MMP loss. In addition, KuB could decrease MDA levels while increasing SOD activity. Meanwhile, KuB decreased NADPH oxidase-mediated ROS production, inhibited Ca(2+) influx, and increased the Bcl-2/Bax ratio. Furthermore, KuB not only down-regulated expression of the NR2B subunit of NMDAR but also actively modulated expression of the signaling molecules downstream of NR2B, including p-ERK, p-CREB, p-AKT and SAPKs. Finally, docking results showed that KuB had a high affinity for NR2B-containing NMDARs. Therefore, we conclude that KuB protected the SH-SY5Y cells from NMDA-induced injury likely by antagonizing NMDARs and reducing oxidative stress.

Free bacterial lipopolysaccharide (LPS) is generally removed from the bloodstream through hepatic uptake via TLR4, the LPS pattern recognition receptor, but mechanisms for internalization and clearance of conjugated LPS are less clear. Kukoamine B (KB) is a novel cationic alkaloid that interferes with LPS binding to TLR4. In this study, KB accelerated blood clearance of LPS. KB also enhanced LPS distribution in the hepatic tissues of C57 BL/6 mice, along with LPS uptake in primary hepatocytes and HepG2 cells. By contrast, KB inhibited LPS internalization in Kupffer and RAW 264.7 cells. Loss of TLR4 did not affect LPS uptake into KB-treated hepatocytes. We also detected selective upregulation of the asialoglycoprotein receptor (ASGPR) upon KB treatment, and ASGPR colocalized with KB in cultured hepatocytes. Molecular docking showed that KB bound to ASGPR in a manner similar to GalNAc, a known ASGPR agonist. GalNAc dose-dependently reduced KB internalization, suggesting it competes with KB for ASGPR binding, and ASGPR knockdown also impaired LPS uptake into hepatocytes. Finally, while KB enhanced LPS uptake, it was protective against LPS-induced inflammation and hepatocyte injury. Our study provides a new mechanism for conjugated LPS hepatic uptake induced by the LPS neutralizer KB and mediated by membrane ASGPR binding.
