All dates were analyzed by the principal component analysis through using the SIMCA-P 10.0 software. Result: The PCA demonstrated that the metabolome between treated group and control group had difference in rat urine sample after of 22 days administrated, for treated group 169 kinds of biomarkers were found including oxalacetic acid, malic acid, 2-ketoglutaric acid, NE, arachidonic acid, 5-HIAA and other compounds, the result was consistent with pharmacological effects of R.coptidis , such as antiinflammatory, inhibiting biosynthesis of CA biosynthesis, anti-central nerve and energy metabolism inhibition.

结果：给药22 d，黄连组与对照组大鼠尿样代谢组有较大差异，发现了169个生物标记物，其中可能的化合物为草酰乙酸、苹果酸、2-酮戊二酸、去甲肾上腺素、花生四烯酸、5-羟吲哚乙酸等物质，这与黄连抗炎、阻止儿茶酚胺的生物合成、抑制中枢神经、降低能量代谢的药理作用相一致。

When those enzymes are activated by AMPK, they would shut down the energy-consuming biosynthesis pathway and turn on the energy-producing fatty acid oxidation pathway.

他们的活性受到抑制后，能够关闭消耗大量ATP的生物合成代谢途径而打开产生大量ATP的生物分解代谢途径。

Particular emphasis is placed on evaluating the significance of the effects of such toxicants on human health.

涉及到与天然毒物相关的生物化学、生物合成、化学、流行病学、免疫学、新陈代谢、营养学、药理学和病理生理学。

Besides their physiological functions in the biosynthesis of phenylpropanoid, terpenoid and fatty acid, CYP450s metabolize exogenous chemicals including herbicides.

它不但能够催化苯丙烷类、萜类化合物和脂肪酸等内源性物质的生物合成，而且参与许多外源性物质包括除草剂等的生物氧化。

The basic concept is combining metabolic pathways in different organisms on a genetic level. As a consequence heterologous organisms provide precursors from their own primary and secondary metabolism that are metabolised to the desired secondary product due to the expression of foreign genes.

组合生物合成是得到新颖天然产物的一种新型工具，并且可以用于生产稀有珍贵的天然产物，其基本概念是在基因水平上将不同有机体的代谢途径结合起来，从而使异源性生物通过外源基因的表达代谢出期望的次生代谢产物，然后从它们的主要代谢和次生代谢中得到想要的前体。
