  Metabolic mechanism and anti-inflammation effects of sinomenine and its major metabolites N-demethylsinomenine and sinomenine-N-oxide

  摘要：

  Aims: Sinomenine (SIN) is clinically used as an anti-rheumatic drug. However, the metabolic and pharmacological mechanisms of SIN combined with its metabolites are unclear. This study aims to explore the cyclic metabolic mechanism of SIN, the anti-inflammation effects of SIN and its major metabolites (N-demethylsinomenine (DS) and sinomenine-N-oxide (SNO)), and the oxidation property of SNO.Materials and methods: SIN was administrated to rats via gavage. Qishe pills (a SIN-containing drug) were orally administrated to humans. The bio-samples were collected to identify SIN'S metabolites. Enzymatic and nonenzymatic incubations were used to reveal SIN'S metabolic mechanism. Impacts of SIN, SNO and DS on the inflammation-related cytokine's levels and nuclear translocation of NF-kappa B were evaluated in LPS-induced Raw264.7 cells. ROS induced by SNO (10 mu M) was also assessed.Key findings: CYP3A4 and ROS predominantly mediated the formation of SNO, and CYP3A4 and CYP2C19 primarily mediated the formation of DS. Noteworthily, SNO underwent N-oxide reduction both enzymatically, by xanthine oxidase (XOD), and non-enzymatically, by ferrous ion and heme moiety. The levels of IL-6 and TNF-alpha and nuclear translocation of NF-kappa B were ameliorated after pretreatment of SIN in LPS-induced Raw264.7 cells, while limited attenuations were observed after pretreatment of DS (SNO) even at 200 mu M. In contrast, SNO induced ROS production.Significance: This study elucidated that SIN underwent both enzymatic and non-enzymatic cyclic metabolism and worked as the predominant anti-inflammation compound, while SNO induced ROS production, suggesting more studies of SIN combined with SNO and DS are necessary in case of DDI and potential toxicities.

  production has been recognized as a potential means for the treatment of rheumatoid arthritis (RA). In order to discover more potent inhibitors and explore the preliminary structure activity relationship, a series of unique stereodimers of sinomenine analogues were designed and synthesized. Their inhibitory activity on NO production and cytotoxicity were evaluated using LPS-activated murine macrophages

  抑制过量NO的产生已被认为是治疗类风湿关节炎（RA）的潜在手段。为了发现更多有效的抑制剂并探索初步的结构活性关系，设计并合成了一系列独特的青藤碱类似物立体异构体。分别使用LPS激活的鼠巨噬细胞RAW264.7测定法和MTT方法评估了它们对NO产生的抑制活性和细胞毒性。在这些化合物中，1A，2，图2a，图2b，和4显示出对NO产生有效的抑制活性无明显的细胞毒性。此外，2，图2a和2b中显着抑制iNOS的mRNA表达。有趣的是，（S）-二聚体显示出比（R）-二聚体更好的生物活性。这些化合物可以作为RA治疗的新型治疗药物开发中的主要候选药物。

  Many compound collections used in high-throughput screening are composed of members whose structural complexity is considerably lower than that of natural products. We previously reported a strategy for the synthesis of complex and diverse small molecules from natural products using ring-distortion reactions, called complexity-to-diversity (CtD), and herein, CtD is applied in the synthesis of 16 diverse

  One new morphinane alkaloid, sinomenine N-oxide (1), and one new natural occurring morphinane alkaloid, N-demethylsinomenine (2), together with six known alkaloids, 7,8-didehydro-4-hydroxy-3,7-dimethoxymorphinan-6-ol (3), sinomenine (4), sinoacutine (5), N-norsinoacutine, acutumine, and acutumidine, were isolated from the stems of Sinomenium acutum. Their structures were elucidated on the basis of spectroscopic analysis and chemical methods. Compounds 2, 3, and 5 have protective effects against hydrogen peroxide-induced cell injury.
