Biological Activity of Kukoamine B

Description 1. Kukoamine B is a potent dual inhibitor for both Lipopolysaccharides (LPS) and oligodeoxynucleotides containing CpG motifs (CpG DNA), LPS and CpG DNA are important pathogenic molecules for the induction of sepsis,are drug targets for sepsis treatment, thus kukoamine B is worthy of further investigation as a potential candidate to treat sepsis. 2. Kukoamine B inhibits inflammation in septic mice by reducing the concentrations of plasma LPS, decreasing leukocyte sequestration and interfering with NFκB activation, and, therefore, suppressing the proadhesive phenotype of endothelial cells. 3. Kukoamine B has protective effects against hydrogen peroxide (H2O2) induced cell injury and potential mechanisms in SH-SY5Y cells, it may potentially serve as an agent for prevention of several human neurodegenerative and other disorders caused by oxidative stress.

Neuroprotective effects of Kukoamine B against hydrogen peroxide-induced apoptosis and potential mechanisms in SH-SY5Y cells.[Pubmed:26164594]

Environ Toxicol Pharmacol. 2015 Jul;40(1):230-40.

Oxidative stress mediates the cell damage in several neurodegenerative diseases, including multiple sclerosis, Alzheimer's disease (AD) and Parkinson's disease (PD). This study aimed at investigating the protective effects of Kukoamine B (KuB) against hydrogen peroxide (H2O2) induced cell injury and potential mechanisms in SH-SY5Y cells. Our results revealed that treatment with KuB prior to H2O2 exposure effectively increased the cell viability, and restored the mitochondria membrane potential (MMP). Furthermore, KuB enhanced the antioxidant enzyme activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) and decreased the malondialdehyde (MDA) content. Moreover, KuB minimized the ROS formation and inhibited mitochondria-apoptotic pathway, MAPKs (p-p38, p-JNK, p-ERK) pathways, but activated PI3K-AKT pathway. In conclusion, we believed that KuB may potentially serve as an agent for prevention of several human neurodegenerative and other disorders caused by oxidative stress.

Kukoamine B, a novel dual inhibitor of LPS and CpG DNA, is a potential candidate for sepsis treatment.[Pubmed:21108626]

Br J Pharmacol. 2011 Mar;162(6):1274-90.

BACKGROUND AND PURPOSE: Lipopolysaccharides (LPS) and oligodeoxynucleotides containing CpG motifs (CpG DNA) are important pathogenic molecules for the induction of sepsis, and thus are drug targets for sepsis treatment. The present drugs for treating sepsis act only against either LPS or CpG DNA. Hence, they are not particularly efficient at combating sepsis as the latter two molecules usually cooperate during sepsis. In this study, a natural alkaloid compound Kukoamine B (KB) is presented as a potent dual inhibitor for both LPS and CpG DNA. EXPERIMENTAL APPROACH: The affinities of KB for LPS and CpG DNA were assessed using biosensor technology. Direct interaction of KB with LPS and CpG DNA were evaluated using neutralization assays. Selective inhibitory activities of KB on pro-inflammatory signal transduction and cytokine expression induced by LPS and CpG DNA were analysed by cellular assays. Protective effects of KB in a sepsis model in mice were elucidated by determining survival and circulatory LPS and tumour necrosis factor-alpha (TNF-alpha) concentrations. KEY RESULTS: KB had high affinities for LPS and CpG DNA. It neutralized LPS and CpG DNA and prevented them from interacting with mouse macrophages. KB selectively inhibited LPS- and CpG DNA-induced signal transduction and expression of pro-inflammatory mediators without interfering with signal pathways or cell viability in macrophages. KB protected mice challenged with heat-killed Escherichia coli, and reduced the circulatory levels of LPS and TNF-alpha. CONCLUSIONS AND IMPLICATIONS: This is the first report of a novel dual inhibitor of LPS and CpG DNA. KB is worthy of further investigation as a potential candidate to treat sepsis.
