代谢
口服给药的迷迭香酸(7)在大鼠尿液中含有七种代谢物,通过光谱和化学数据鉴定为:反式-咖啡酸4-O-硫酸酯(1)、反式-m-香豆酸3-O-硫酸酯(2)、反式-阿魏酸4-O-硫酸酯(3)、反式-咖啡酸(4)、m-羟基苯丙酸(5)、反式-m-香豆酸(6)以及未改变的迷迭香酸(7)。口服给药迷迭香酸48小时后,尿液中1-7的总累积排泄量约为给药剂量的31.8%。另一方面,在胆汁中并未发现归属于迷迭香酸的代谢物。因此,可以得出结论,口服给药的迷迭香酸主要通过尿液排泄,而不是胆汁,代谢过程中包括酯键的断裂、选择性的对位去羟基化、甲基化和硫酸结合。代谢物2、3、5和6也出现在血浆中。
The urine of rats administered rosmarinic acid (7) orally contained seven metabolites, which were identified as trans-caffeic acid 4-O-sulfate (1), trans-m-coumaric acid 3-O-sulfate (2), trans-ferulic acid 4-O-sulfate (3), trans-caffeic acid (4), m-hydroxyphenylpropionic acid (5), trans-m-coumaric acid (6), and unchanged rosmarinic acid (7) by spectroscopic and chemical data. The total cumulative amount of 1-7 excreted in the urine 48 h after the oral administration of rosmarinic acid was approximately 31.8% of the dose administered. On the other hand, the metabolites attributed to rosmarinic acid could not be found in the bile. Orally administered rosmarinic acid may thus be concluded to be excreted in the urine rather than in the bile, with cleavage of ester bonds, selective para-dehydroxylation, methylation, and sulfate-conjugation. Metabolites 2, 3, 5, and 6 were also detected in the plasma.

迷迭香酸是积累在紫草科和唇形科植物中的主要羟基肉桂酸酯。通过差示显示法从紫草培养细胞中分离出一种细胞色素P450 cDNA,根据推导的氨基酸序列,基因产物被命名为CYP98A6。在酵母中表达后,显示P450催化了4-香豆酰-4'-羟基苯乳酸的3-羟基化,这是迷迭香酸生物合成途径的最后两个步骤之一。通过向紫草细胞中添加酵母提取物或甲基茉莉酸,CYP98A6的表达平显著提高,其表达模式反映了诱导子引起的迷迭香酸产量变化,表明CYP98A6在迷迭香酸生物合成调控中发挥重要作用。
Rosmarinic acid is the dominant hydroxycinnamic acid ester accumulated in Boraginaceae and Lamiaceae plants. A cytochrome P450 cDNA was isolated by differential display from cultured cells of Lithospermum erythrorhizon, and the gene product was designated CYP98A6 based on the deduced amino acid sequence. After expression in yeast, the P450 was shown to catalyze the 3-hydroxylation of 4-coumaroyl-4'-hydroxyphenyllactic acid, one of the final two steps leading to rosmarinic acid. The expression level of CYP98A6 is dramatically increased by addition of yeast extract or methyl jasmonate to L. erythrorhizon cells, and its expression pattern reflected the elicitor-induced change in rosmarinic acid production, indicating that CYP98A6 plays an important role in regulation of rosmarinic acid biosynthesis.

本研究的目的是在健康人体内确定迷迭香酸(RA)在一次摄入紫苏提取物(PE)后的吸收、代谢和尿液排泄情况。共有六名健康男性(平均年龄37.2 ± 6.2岁,平均体重指数22.0 ± 1.9 kg/m²)参加了这项交叉设计的研究,他们在摄入含有200毫克RA的PE和安慰剂之间有10天的间隔。在摄入前和指定的时间间隔收集血液样本,而尿液样本则是在摄入后0-6小时、6-24小时和24-48小时期间收集。通过LC-MS测量血浆和尿液中RA及其相关代谢物。摄入PE后,在尿液中检测到RA、甲基化RA(甲基-RA)、咖啡酸CAA)、阿魏酸(FA)和微量的香豆酸(COA)。在血浆中,检测到RA、甲基-RA和FA,分别在摄入PE后的0.5小时、2小时和0.5小时达到最大平。血浆和尿液中这些成分的绝大多数以结合形式(葡萄糖醛酸苷和/或硫酸盐)存在。RA及其相关代谢物在尿液中的排泄比例为总剂量的6.3 ± 2.2%,大约75%的这些成分在摄入PE后6小时内被排泄。
The aim of this study in healthy humans was to determine the absorption, metabolism, and urinary excretion of rosmarinic acid (RA) after a single intake of perilla extract (PE). Six healthy men (mean age 37.2 +/- 6.2 y and mean body mass index 22.0 +/- 1.9 kg/sq m) were enrolled in the study that was a crossover design involving single intakes of PE containing 200 mg RA and placebo with a 10 day interval between treatments. Blood samples were collected before intake and at designated time intervals, while urine samples were collected over the periods 0-6 hr, 6-24 hr and 24-48 hr after intake. RA and its related metabolites in plasma and urine were measured by LC-MS. RA, methylated RA (methyl-RA), caffeic acid (CAA), ferulic acid (FA) and a trace of m-coumaric acid (COA) were detected in the urine after intake of PE. In plasma, RA, methyl-RA and FA were detected, with maximum levels obtained 0.5, 2 and 0.5 hr after intake of PE, respectively. The majority of these components in both plasma and urine were present as conjugated forms (glucuronide and/or sulfated). The proportion of RA and its related metabolites excreted in the urine was 6.3 +/- 2.2% of the total dose, with approximately 75% of these components being excreted within 6 hr after intake of PE.

罗斯马里酸(RA),一种咖啡酸酯,在高果糖喂养的胰岛素抵抗(IR)模型中具有增敏胰岛素和抗氧化的效果。本研究探讨了罗斯马里酸补充是否能预防果糖喂养大鼠(FFR)的心脏异常和高血压。用含60克/100克果糖的饮食喂养大鼠60天,表现出代谢异常,以及血浆和心脏脂质以及全身胰岛素抵抗的增加。果糖喂养大鼠的心脏抗氧化剂平和血浆还原抗氧化能力显著降低,同时脂质过氧化和蛋白质氧化产物的平增加。果糖喂养大鼠的血浆中肌蛋白T、肌酸激酶-MB、天门冬酸转移酶和乳酸脱氢酶显著升高。从第16天开始给果糖喂养大鼠补充罗斯马里酸(10毫克/千克)显著改善了胰岛素敏感性,降低了脂质平、氧化损伤和烟酰胺腺嘌呤二核苷酸磷酸还原酶的p22phox亚单位的表达,并预防了心肌肥大。罗斯马里酸还通过减少内皮素-1和血管紧张素转换酶活性以及增加一氧化氮平,降低了果糖诱导的血压升高。组织学检查显示罗斯马里酸补充的果糖喂养大鼠心肌损伤减少。这些发现表明,罗斯马里酸通过其抗氧化性质作为一种血管活性物质和心脏保护剂发挥作用。因此,罗斯马里酸可能有助于减少与胰岛素抵抗相关的心血管风险。
Rosmarinic acid (RA), a caffeic acid ester, has insulin-sensitizing and antioxidant effects in high fructose-fed model of insulin resistance (IR). This study investigated whether RA supplementation prevents cardiac abnormalities and hypertension in fructose-fed rats (FFR). Rats fed with fructose diet (60 g/100 g) for 60 days exhibited metabolic abnormalities and rise in plasma and cardiac lipids and whole body IR. The levels of cardiac antioxidants and plasma ferric reducing antioxidant power were significantly reduced in FFR concomitant with increased levels of lipid peroxidation and protein oxidation products. A significant rise in troponin T, creatine kinase-MB, aspartate transaminase, and lactate dehydrogenase in plasma of FFR was noted. RA supplementation to FFR (10 mg/kg from the 16th day) significantly improved insulin sensitivity, reduced lipid levels, oxidative damage, and the expression of p22phox subunit of nicotinamide adenine dinucleotide phosphate reduced oxidase, and prevented cardiac hypertrophy. Fructose-induced rise in blood pressure was also lowered by RA through decrease in endothelin-1 and angiotensin-converting enzyme activity and increase in nitric oxide levels. Histology revealed a reduction in myocardial damage in RA-supplemented FFR. These findings suggest that RA acts as a vasoactive substance and a cardioprotector through its antioxidant property. Thus, RA may be useful in reducing the cardiovascular risk associated with IR.

流行病学和实验研究已经表明,柴油机尾气颗粒(DEP)可能与近年来肺部疾病增加有关。DEP已被证明能产生反应性氧种。将DEP注入气管会在小鼠中诱导肺部炎症和肿。迷迭香酸是一种天然存在的多,具有抗氧化和抗炎活性。本研究调查了迷迭香酸对通过气管内给药DEP(500微克/体重)在小鼠中诱导的肺损伤的影响。口服补充迷迭香酸(2毫克/体重,连续3天)抑制了DEP诱导的肺损伤,这种损伤的特点是中性粒细胞的滞留和间质性肿。DEP增强了肺中角蛋白细胞化学吸引剂(KC)、白细胞介素-1beta、单核细胞化学吸引蛋白-1和巨噬细胞炎症蛋白-1alpha的表达,而这种表达被迷迭香酸治疗所抑制。DEP增强了肺中iNOS mRNA的表达以及硝基酪氨酸和8-OHdG的形成,这些也被迷迭香酸抑制。这些结果表明,迷迭香酸通过减少促炎分子表达来抑制DEP诱导的肺损伤。迷迭香酸的抗氧化活性也可能对其保护效果有所贡献。
Epidemiological and experimental studies have suggested that diesel exhaust particles (DEP) may be involved in recent increases in lung diseases. DEP has been shown to generate reactive oxygen species. Intratracheal instillation of DEP induces lung inflammation and edema in mice. Rosmarinic acid is a naturally occurring polyphenol with antioxidative and anti-inflammatory activities. /This/ investigated the effects of rosmarinic acid on lung injury induced by intratracheal administration of DEP (500 ug/body) in mice. Oral supplementation with administration of rosmarinic acid (2 mg/body for 3 d) inhibited DEP-induced lung injury, which was characterized by neutrophil sequestration and interstitial edema. DEP enhanced the lung expression of keratinocyte chemoattractant (KC), interleukin-1beta, monocyte chemoattractant protein-1, and macrophage inflammatory protein-1alpha, which was inhibited by treatment with rosmarinic acid. DEP enhanced expression of iNOS mRNA and formation of nitrotyrosine and 8-OHdG in the lung, which was also inhibited by rosmarinic acid. These results suggest that rosmarinic acid inhibits DEP-induced lung injury by the reduction of proinflammatory molecule expression. Antioxidative activities of rosmarinic acid may also contribute to its protective effects.

迷迭香酸(RA),一种多酚类植物化学物质,是一种天然的脯酰寡肽酶抑制剂。/当前研究/发现,RA在由脂多糖(LPS)诱导的急性肺损伤(ALI)的体内模型中发挥了强大的抗炎作用。小鼠在挑战前一小时接受RA预处理,剂量为0.5 mg/kg LPS。在给予LPS后24小时,获取支气管肺泡灌洗液(BALF)以测量促炎介质和总细胞数。与LPS组相比,RA显著减少了LPS诱导的TNF-a、IL-6和IL-1beta的产生。当预先用RA(5、10或20 mg/kg)处理时,肺组织的肺湿重/干重(W/D)比率和BALF中的总细胞数、中性粒细胞和巨噬细胞数量显著减少。此外,RA可能通过增强氧化酶二聚酶(SOD)的活性来应对LPS诱导的ALI的炎症反应。并且/作者/进一步证明,RA通过以剂量依赖性方式抑制ERK/MAPK信号传导,在ALI的体内模型中发挥抗炎作用...
Rosmarinic acid (RA), a polyphenolic phytochemical, is a natural prolyl oligopeptidase inhibitor. /The present study/ found that RA exerted potent anti-inflammatory effects in in vivo models of acute lung injury (ALI) induced by lipopolysaccharide (LPS). Mice were pretreated with RA one hour before challenge with a dose of 0.5 mg/kg LPS. Twenty-four hours after LPS was given, bronchoalveolar lavage fluid (BALF) was obtained to measure pro-inflammatory mediator and total cell counts. RA significantly decreased the production of LPS-induced TNF-a, IL-6, and IL-1beta compare with the LPS group. When pretreated with RA (5, 10, or 20 mg/kg) the lung wet-to-dry weight (W/D) ratio of the lung tissue and the number of total cells, neutrophils and macrophages in the BALF were decreased significantly. Furthermore, RA may enhance oxidase dimutase (SOD) activity during the inflammatory response to LPS-induced ALI. And /the authors/ further demonstrated that RA exerts anti-inflammation effect in vivo models of ALI through suppresses ERK/MAPK signaling in a dose dependent manner...

本研究旨在探讨迷迭香酸对小鼠乙醇诱导的DNA损伤的保护作用。通过使用迷迭香酸(100 mg/kg)进行预处理、共同处理和后处理乙醇(5 g/kg),测试了迷迭香酸的抗原毒性能力。使用彗星试验评估外周血(1小时和24小时)和脑细胞(24小时),并使用微核试验分析骨髓(24小时)。结果与TBARS、具有抗氧化活性的酶和DCFH-DA试验的数据进行了比较。外周血和脑细胞显示,与乙醇组相比,迷迭香酸预处理组的平均损伤指数(DI)和损伤频率(DF)值显著降低。在脑细胞中,与乙醇组相比,所有不同的迷迭香酸乙醇处理均显著降低了DI和DF的平均值。各组之间微核频率、抗氧化酶活性和TBARS没有显著差异。DCFH-DA试验显示,与乙醇组相比,荧光强度降低了18%。结果表明,迷迭香酸可以降低乙醇诱导的DNA损伤平,适用于这两种组织和处理时期。
The aim of the present work was to study the protective effects of rosmarinic acid against ethanol-induced DNA damage in mice. The antigenotoxic capacity of rosmarinic acid (100 mg/kg) was tested using pre-, co- and post-treatment with ethanol (5 g/kg). Peripheral blood (1 and 24 hr) and brain cells (24 hr) were evaluated using the comet assay and bone marrow was analyzed using the micronucleus assay (24 hr). The results were compared to data of TBARS, enzymes with antioxidant activity, and DCFH-DA test. Peripheral blood and brain cells show that mean damage index (DI) and damage frequency (DF) values of ethanol with pre-treatment with rosmarinic acid group were significantly lower than in the ethanol group. In brain cells all different treatments with ethanol and rosmarinic acid showed significant decrease in DI and DF mean values when compared to ethanol group and negative control. No significant differences were observed in micronucleus frequency, activity of antioxidant enzymes and TBARS between groups. The DCFH-DA test show a reduction of 18% of fluorescence intensity when compare with ethanol group. The results show that rosmarinic acid could decrease the levels of DNA damage induced by ethanol, for both tissues and treatment periods.

研究的目的是调查迷迭香酸(RA)的经皮吸收、组织分布和绝对生物利用度。在离体实验中,RA从酒精溶液中透过大鼠皮肤的渗透率是从中透过的大约8倍,这表明乙醇可能作为吸附促进剂。从酒精溶液的流量分别是4.4或10微克/平方厘米/小时,tleg(渗透平衡时间)分别是7.8或3.7小时。静脉给药后,RA最好用2室开放模型来描述;t1/2(半衰期)= 1.8小时,t1/2 alpha(分布相半衰期)= 0.07小时,V tau(中央室体积)= 2.3升/千克,V beta(周边室体积)= 15.3升/千克。当以W/O乳膏形式(25毫克/千克,50平方厘米)局部给药时,RA的绝对生物利用度为60%。静脉给药后0.5小时,在大脑、心脏、肝脏、肺、肌肉、脾脏和骨骼组织中检测到并测量了RA,其中肺组织中的浓度最高(是血液浓度的13倍),其次是脾脏、心脏和肝脏组织。在大约20平方厘米的后腿上局部给药约3毫克后4.5小时(峰值时间),在血液、皮肤、肌肉和骨骼组织中测量到了RA。
The purpose of the study was to investigate the transdermal absorption of rosmarinic acid (RA), its tissue distribution and absolute bioavailability. In ex vivo experiments, permeation of RA across excised rat skin was about 8 times higher from alcoholic solution than from water, indicating that ethanol may act as sorption promoter. The flux from water or alcoholic solution was 4.4 or 10 ug/sq cm/hr, and the tleg was 7.8 or 3.7 hr, respectively. After I.V. administration, RA is best described by a 2-compartment open model; t1/2 = 1.8 hr, t1/2 alpha = 0.07 hr, V tau = 2.3 L/kg, V beta = 15.3 L/kg. Upon topical administration of RA in form of a W/O ointment (25 mg/kg, 50 sq cm), the absolute bioavailability was 60%. 0.5 hours after iv administration, RA was detected and measured in brain, heart, liver, lung, muscle, spleen and bone tissue, showing the highest concentration in lung tissue (13 times the blood concentration), followed by spleen, heart and liver tissue. 4.5 hours (peak time) after topical administration of about 3 mg on the hind leg over 20 sq cm, RA was measured in blood, skin, muscle and bone tissue.

    Isolation and Characterization of a Novel Tannase from a Metagenomic Library
    摘要:
    A novel gene (designated as tan410) encoding tannase was isolated from a cotton field metagenomic library by functional screening. Sequence analysis revealed that tan410 encoded a protein of 521 amino acids. SDS PAGE and gel filtration chromatography analysis of purified tannase suggested that Tan410 was a monomeric enzyme with a molecular mass of SS kDa. The optimum temperature and pH of Tan410 were 30 degrees C and 6.4. The activity was enhanced by addition of Ca2+, Mg2+ and Cd2+. In addition, Tan410 was stable in the presence of 4 M NaCl. Chlorogenic acid, rosmarinic acid, ethyl ferulate, tannic acid, epicatechin gallate and epigallocathchin gallate were efficiently hydrolyzed by recombinant tannase. All of these excellent properties make Tan410 an interesting enzyme for biotechnological application.

    摘要:
    乳腺癌是对社会造成高负担的恶性肿瘤,其影响推动了对新型诊断和治疗工具的不断探索。在最近的治疗方法中,光热疗法(PTT)是一种高潜力的策略,通过光源照射后引起肿瘤细胞死亡。此外,将近红外(NIR)辐射与金纳米粒子(AuNPs)作为光热增强剂相结合,可以提高PTT的效果。本文报道了一种使用迷迭香酸(RA)合成AuNPs的替代合成方法。 RA浓度有所变化,并评估其对AuNPs物理化学和光学特性的影响。结果表明,RA浓度对AuNPs特性起着积极作用,允许优化平均大小和最大吸收峰。此外,本文探讨的合成方法使我们能够获得负电荷的AuNPs,其大小有利于在肿瘤部位局部粒子积累,并在NIR区域内具有最大吸收峰。此外,AuNPs在体外和体内均安全。总之,合成的AuNPs具有有利的特性,可作为将AuNPs与NIR激光相结合用于乳腺癌治疗的PTT系统的一部分。

    transfer, number of radicals scavenged per antioxidant molecule, BDE and formation of antioxidant dimers from the primary radicals play an important role regarding the antioxidant activity of phenols. Based on this, it is finally shown that myricetin, rosmarinic and carnosic acids are more efficient than α-tocopherol and synthetic antioxidants for the preservation of omega-3 oils.
    22种天然多与7种合成抗氧化剂(包括BHTBHATBHQPG)在保护omega-3油免于自氧化方面的能力进行了比较。使用DPPH评估酚类的抗氧化效率富含omega-3脂肪酸的油的自氧化过程中的测试和耗氧量的测量。同样,计算了Ar-OH键的键解离焓(BDE),并获得了热力学,动力学和氧化数据之间的极佳相关性。结果表明,氢转移的动力学速率,每个抗氧化剂分子清除的自由基数量,BDE以及由初级自由基形成的抗氧化剂二聚体在酚类抗氧化剂活性方面起着重要作用。基于此,最终表明,在保存omega-3油方面,杨梅素迷迭香酸肌酸比α-生育酚和合成抗氧化剂更有效。
  • Derivatization of Rosmarinic Acid Enhances its in vitro Antitumor, Antimicrobial and Antiprotozoal Properties

    On its own, rosmarinic acid possesses multiple biological activities such as anti-inflammatory, antimicrobial, cardioprotective and antitumor properties, and these are the consequence of its ROS scavenging and inhibitory effect on inflammation. In this study, two quaternary phosphonium salts of rosmarinic acid were prepared for the purpose of increasing its penetration into biological systems with the aim of improving its antimicrobial, antifungal, antiprotozoal and antitumor activity. The synthetized molecules, the triphenylphosphonium and tricyclohexylphosphonium salts of rosmarinic acid, exhibited significantly stronger inhibitory effects on the growth of HCT116 cells with IC50 values of 7.28 or 8.13 μM in comparison to the initial substance, rosmarinic acid (>300 μM). For the synthesized derivatives, we detected a greater than three-fold increase of activity against Acanthamoeba quina, and a greater than eight-fold increase of activity against A. lugdunensis in comparison to rosmarinic acid. Furthermore, we recorded significantly higher antimicrobial activity of the synthetized derivatives when compared to rosmarinic acid itself. Both synthetized quaternary phosphonium salts of rosmarinic acid appear to be promising antitumor and antimicrobial agents, as well as impressive molecules for further research.

    独立的迷迭香酸具有多种生物活性,如抗炎、抗菌、心脏保护和抗肿瘤特性,这些是其清除ROS和抑制炎症作用的结果。在这项研究中,为了增加其在生物系统中的渗透性以提高其抗菌、抗真菌、抗原虫和抗肿瘤活性,制备了两种迷迭香酸的季盐。合成的分子,三苯基三环己基盐的迷迭香酸,在抑制HCT116细胞生长方面表现出显著更强的效果,IC50值为7.28或8.13μM,而原始物质迷迭香酸(>300μM)。对于合成的衍生物,我们检测到对棘阿米巴和卢格登氏棘阿米巴的活性增加了三倍以上,对比迷迭香酸,对A. lugdunensis的活性增加了八倍以上。此外,与迷迭香酸相比,我们记录到合成的衍生物具有显著更高的抗菌活性。迷迭香酸的两种合成季盐似乎是有前途的抗肿瘤和抗菌剂,也是进一步研究的令人印象深刻的分子。
