A new strategy of enhancing absorptivity and safety for evodiamine: polyamidoamine derivatives modified by polyethylene glycol chain

Background:Traditional Chinese medicine involves complex ingredients and mixtures of ingredients that often exhibit low bioavailability,and excipients are often lacking to increase the absorption-enhancing effects.This study modified the generation 4 polyamidoamine dendrimer with polyethylene glycol of different molecular weights(5000,2000,1000)to form a series of polyamidoamine-co-polyethylene glycol(PAMAM-co-PEG)as a novel class of oral absorption enhancers.Evodiamine,the major alkaloid found in the traditional Chinese medicine Wu Zhu Yu(Fructus Evodiae),was used as a model drug to verify the absorption-enhancing effects and the safety of this alkaloid.Methods:This study utilized the solubility determination method documented in the Pharmacopoeia of the People’s Republic of China(2015 edition)and the D0 values recommended in the US FDA guidelines to comprehensively evaluate the solubility of evodiamine.The permeability of evodiamine was assessed using the apparent permeability coefficient in experiments based on in vitro cell models.Multiple aspects of the biological safety of PAMAM-co-PEG were explored using the MTT assay,LDH assay,and total protein release of the rat intestinal tract.Moreover,the absorption-enhancing effects of PAMAM-co-PEG at different molecular weights on evodiamine were verified via the use of in vitro cell models and in vivo intestinal loop circulation experiments with rats.Results:Evodiamine exhibited low solubility and permeability and was classified into class IV compounds using the biopharmaceutical classification system.PAMAM-co-PEG 2000 demonstrated improvement in the biosafety and absorption-enhancement effect of evodiamine at a specific concentration.This study showed that 0.05%(w/v)of PAMAM-co-PEG 2000 increased the cumulative penetration of evodiamine via cell transport by 1.32 times,and 0.10%(w/v)of PAMAM-co-PEG 2000 increased the area under curve value of evodiamine by 1.31 times.Conclusion:Evodiamine possesses low solubility and permeability and leads to poor oral bioavailability and a certain degree of cytotoxicity.PAMAM-co-PEG 2000 was found to be a potentially safe and efficient oral absorption enhancer.The results of this study might create a foundation for the development of novel excipients suitable for the complex active ingredients of traditional Chinese medicine.

Erk1/2, CDK8, Src and Ck1e Mediate <i>Evodia rutaecarpa</i>Induced Hepatotoxicity in Mice

Evodia rutaecarpa (E.R.) is a commonly used Chinese herbal medicine. However, it exerts certain hepatotoxicity and the underlying molecular mechanism has not been clarified. In this study, we investigated the molecular mechanism involved in hepatotoxicity induced by E.R. Mice were treated with E.R. water- and ethanol-extract at dosage equivalent to 16.67 g crude-drug/kg body weight by intragastric administration once a day on 30 consecutive days. The effect of E.R. extract on liver, manifested by histopathologic effects, liver index, and blood biochemical indexes were tested. In addition, interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor (TNF)-α in liver tissue were measured. The signaling transduction molecules were determined by antibody microarray assay, and verified by western blot. E.R. extract, either water- or ethanol-extract, can induce liver dysfunction. Signaling molecules, Erk1/2, Src, CDK8 and CK1e, were involved in this process. E.R. extract can induce Ck1e expression and phosphorylation of Erk1/2 and CDK8, and inhibit Src phosphorylation. Inflammatory cytokines in liver tissue, IL-1β, IL-6, IL-8, and TNF-α were markedly increased upon the treatment of E.R. extract. In conclusion, E.R.-induced hepatotoxicity was due to the expression of inflammatory cytokine, which was mediated through Erk1/2, Src, CDK8 and CK1e.

An Improved Method of Simultaneous Determination of Four Bioactive Compounds in Evodiae Fructus Using Ionic Liquids as Mobile Phase Additives in High Performance Liquid Chromatography

There are many compounds with different structures and chemical properties in Evodiae Fructus. It is hard to simultaneously determine the bioactive compounds by high performance liquid chromatography（HPLC）. A new method was proposed for four bioactive compounds（synephrine, limonoids, evodiamine and rutecarpine） to be separated completely and determined accurately using ionic liquids（ILs） as mobile phase additives. The mechanism and the effect of the ILs for changing the chromatographic behaviors of the four compounds were studied by systemati- cally changing the pH value of mobile phase, the types and concentrations of ILs as well as the concentrations of phosphate buffer. The chromatographic behaviors of the analytes with a mobile phase containing ILs complied with the stoichiometric displacement model for retention（SDM-R）. All results demonstrate the dual nature of ionic liquids, which are competitive adsorption and ion-pair agent. Meanwhile, excellent linearity was observed for all the com- pounds with correlation coefficients between 0.9992 and 0.9998. The limit of detection and the limit of quantification of the four compounds varied from 0.47μg/mL to 0.87 μg/mL and from 1.79 μg/mL to 2.44μg/mL, respectively. Three kinds of Evodiae Fructus processed through different methods were analyzed via the method. The result shows that the contents of evodiamine and rutecarpine as the two main active compounds by processing with vinegar and salt are obviously higher than those of the raw products.
