OBJECTIVE To screen the effective components and potent substances of Bletilla striata and to preliminarily predict its mechanism of action. METHODS Oxford cup and microdilution methods were used to evaluate the inhibition of Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus in different extracted parts of Bletilla striata. Subsequently, a mouse model of acne vulgaris was established to assess the effects of the different extracted components of Bletilla striata on auricular tissue lesions, histopathology, and inflammatory factors. Furthermore, the chemical compositions of the three extracts were analyzed using ultra high performance liquid chromatography-tandem quadrupole mass spectrometry (UPLC-Q-TOF-MS). Network pharmacology was utilized to predict the relevant targets, pharmacodynamic components, and related pathways of Bletilla Striata in the treatment of acne. Additionally, molecular docking was performed on the key pharmacodynamic components and targets to further validate these pharmacodynamic substances. RESULTS The ethyl acetate extract of Bletilla striata could effectively inhibit three kinds of acne-causing bacteria, and its MIC was 2.34, 2.34, 4.59 mg·mL-1, respectively, the ethyl acetate extract of Bletilla striata significantly improved the auricular tissue lesions in mice, while the remaining two extracts exhibited no anti-acne effect. A total of 51 components of Bletilla striata were identified, including 48 components in the ethyl acetate extract, 13 components in the butanol extract, and 15 components in the water extract, stilbenes were most enriched in the ethyl acetate extract. The results of network pharmacology and molecular docking validation indicated that constituents such as batatasin Ⅲ, 3-(4-hydroxybenzyl)-4-methoxy-2, 7-dihydroxy-9, 10-dihydrophenanthreneand, 3-O-methylbatatasin Ⅲ may serve as key active constituents of Bletilla striata in the treatment of acne. Additionally, MAPK1 and TNF among others may represent potential targets of Bletilla striata in anti-acne therapy. CONCLUSION This study shows that the ethyl acetate extracted parts of Bletilla striata have good anti-acne effects, in which the Stilbenes represented by batatasin Ⅲ may be the main medicinal components, which may provide important references for the in-depth study of the mechanism of Bletilla striata in treating acne.

目的 筛选白及抗痤疮有效部位,预测其潜在活性成分及作用机制。方法 采用体外抑菌实验、小鼠复合痤疮模型评价白及不同萃取部位抗痤疮丙酸杆菌、表皮葡萄球菌、金黄色葡萄球菌的活性和对小鼠耳廓组织皮损、组织病理学、组织中炎症因子等指标的影响,筛选白及抗痤疮有效部位;采用超高效液相色谱-串联四极杆飞行时间质谱(UPLC-Q-TOF-MS)技术分析比较3个部位的化学成分;利用网络药理学预测白及治疗痤疮的相关靶点、药效成分及相关通路,对其关键药效成分和靶点进行分子对接,进一步验证其药效物质及靶点。结果 白及乙酸乙酯部位可以有效抑制3种痤疮致病菌,其最低抑菌浓度(MIC)分别为2.34、2.34、4.59 mg·mL-1,可以显著改善小鼠耳廓组织病损等情况,其余两个部位均无抗痤疮作用;共鉴定白及共51个成分,其中乙酸乙酯部位48个成分,正丁醇部位13个成分,水部位15个成分,芪类化合物富集在乙酸乙酯部位中;网络药理学和分子对接验证结果显示山药素Ⅲ(batatasin Ⅲ)、3-(4-羟基苄基)-4-甲氧基-2,7-二羟基-9,10-二氢菲[3-(4-hydroxybenzyl)-4-methoxy-2,7-dihydroxy-9,10-dihydrophenanthrene]、3-O-甲基山药素Ⅲ(3-O-methylbatatasin Ⅲ)等成分可能为白及治疗痤疮的关键活性成分,丝裂原活化蛋白激酶(MAPK1)和肿瘤坏死因子(TNF)等可能是白及抗痤疮的潜在靶点。结论 白及乙酸乙酯萃取部位具有良好的抗痤疮作用,其中以山药素Ⅲ为代表的芪类化合物可能是其主要药效成分,可为深入研究白及治疗痤疮的机制研究提供重要参考。

OBJECTIVE To screen the effective components and potent substances of Bletilla striata and to preliminarily predict its mechanism of action. METHODS Oxford cup and microdilution methods were used to evaluate the inhibition of Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus in different extracted parts of Bletilla striata. Subsequently, a mouse model of acne vulgaris was established to assess the effects of the different extracted components of Bletilla striata on auricular tissue lesions, histopathology, and inflammatory factors. Furthermore, the chemical compositions of the three extracts were analyzed using ultra high performance liquid chromatography-tandem quadrupole mass spectrometry (UPLC-Q-TOF-MS). Network pharmacology was utilized to predict the relevant targets, pharmacodynamic components, and related pathways of Bletilla Striata in the treatment of acne. Additionally, molecular docking was performed on the key pharmacodynamic components and targets to further validate these pharmacodynamic substances. RESULTS The ethyl acetate extract of Bletilla striata could effectively inhibit three kinds of acne-causing bacteria, and its MIC was 2.34, 2.34, 4.59 mg·mL-1, respectively, the ethyl acetate extract of Bletilla striata significantly improved the auricular tissue lesions in mice, while the remaining two extracts exhibited no anti-acne effect. A total of 51 components of Bletilla striata were identified, including 48 components in the ethyl acetate extract, 13 components in the butanol extract, and 15 components in the water extract, stilbenes were most enriched in the ethyl acetate extract. The results of network pharmacology and molecular docking validation indicated that constituents such as batatasin Ⅲ, 3-(4-hydroxybenzyl)-4-methoxy-2, 7-dihydroxy-9, 10-dihydrophenanthreneand, 3-O-methylbatatasin Ⅲ may serve as key active constituents of Bletilla striata in the treatment of acne. Additionally, MAPK1 and TNF among others may represent potential targets of Bletilla striata in anti-acne therapy. CONCLUSION This study shows that the ethyl acetate extracted parts of Bletilla striata have good anti-acne effects, in which the Stilbenes represented by batatasin Ⅲ may be the main medicinal components, which may provide important references for the in-depth study of the mechanism of Bletilla striata in treating acne.

痤疮是一种毛囊皮脂腺的慢性炎症性疾病[1],易发于面、背、胸等富含皮脂腺的部位。其目前已经是全球第2大皮肤病,其发病因素复杂、病程反复,因多发生于青春期男女,且愈后易发生瘢痕增生及色素沉着,会对患者的心理健康造成一定影响。目前现代治疗中多使用西药凝胶,存在易产生耐药性、副作用多、效果不佳等问题,然而中药外用美颜美容的历史悠久,具有独特的药效活性,副作用小。但中药类产品的使用过程中因其未明确药效活性成分而得不到发展,因此扩大中草药等产品的开发以及明确其确切的物质基础成为现在需要首要解决的难题。
白及为兰科植物白及[Bletilla striata (Thunb.) Reichb.f.]的干燥块茎,具有收敛止血、消肿生肌的功效,主治疮疡肿痛、外伤出口、手足皲裂等证。除此之外,白及自古以来就是一味美容要药,在《本草纲目》《本草备药》《本草求真》《本草从新》等古籍中均有其美白、润肤、祛面疮的记载,本草记载的多为白及药效,对于白及在润肤美颜上的应用还是以经验医学为主,例如《普济方》中由白及、白蔹等组成的药方可治疗“发于肌肤而为浸淫疮。”《外台秘要》中由白及组方的面脂方“主面及皲皱靥黑皯,凡是面上之病,皆悉主之。”《御药院方》中由白及白蔹白芷组成的善应膏可以治疮肿,小儿头面疮丹流,聚热杂疮。但目前白及现代研究集中在白及多糖、止血、黏膜愈合、抗炎、抗溃疡等领域[2-4],对其改善痤疮的研究较浅显,且未明确药效物质基础。因此本实验通过药效活性筛选,寻找白及治疗痤疮的有效部位,结合超高效液相色谱-串联四极杆飞行时间质谱(UPLC-Q-TOF-MS)技术分析白及不同萃取部位的化学成分,同时利用网络药理学和分子对接挖掘白及抗痤疮的药效成分及其作用的痤疮靶点,以期阐明白及治疗痤疮的物质基础并初步预测其作用机制。

测试的3种菌株在琼脂板上划线,金黄色葡萄球菌、表皮葡萄球菌37 ℃培养24 h(痤疮丙酸杆菌放置在厌氧袋中37 ℃培养48 h)。
挑取形态良好的单菌落置于生理盐水中,摇匀,采用麦氏比浊管进行比对,调节菌液浓度至0.5 个麦氏浊度(1×108 CFU·mL-1),并进一步稀释至1×106 CFU·mL-1,4 ℃贮存备用。
按照参考文献[5]中的方法,采用牛津杯法以评估不同白及提取物对痤疮丙酸杆菌、表皮葡萄球菌、金黄色葡萄球菌的抑制作用。在固体培养基平板表面接种0.1 mL菌悬液并涂布均匀,采用十字交叉法放置已灭菌的牛津杯;将上述配置的白及乙酸乙酯提取液、白及正丁醇提取液、白及水提取液药液在试管中分别倍比稀释4次,依次将初始浓度及稀释后的不同浓度提取药液0.1 mL加入孔内。将培养基平板放入37 ℃恒温培养箱中培养24~48 h(痤疮丙酸杆菌培养基平板装入厌氧袋,放入37 ℃恒温培养箱中培养48~72 h)。以各自溶剂为空白对照组。每菌3个重复。抑菌圈直径等于抑菌透明圈的直径(mm)与牛津杯的外径(mm)的差。
采用微量液基稀释法结合碘硝基四唑紫指示剂法测定BSE对痤疮丙酸杆菌、表皮葡萄球菌、金黄色葡萄球菌的MIC。以BHI肉汤、LB肉汤为稀释液,在96孔板(每孔100 μL)中配制白及各提取部位药液的系列两倍稀释液,每孔加入100 μL菌悬液,使其终质量浓度为150~0.59 mg·mL-1,空白溶剂作为阴性对照。表皮葡萄球菌、金黄色葡萄球37 ℃培养24 h(痤疮丙酸杆菌37 ℃厌氧培养48 h)后,向孔中加30 μL 0.5%碘硝基四唑紫溶液作为指示剂,37 ℃培养1.5 h,每菌3个重复。碘硝基四唑紫可以结合活性菌形成紫色的染色复合物,因此MIC被计算为未变紫孔中的最低药物浓度。
分别吸取提取物质量浓度为1/2 MIC、MIC、2 MIC、4 MIC的菌悬液20 μL,均匀涂于琼脂板,37 ℃培养24 h,取出,观察计数,以≤5个菌落数者为MBC。

每日观察小鼠进食量、活动、精神状况和小鼠左耳耳廓损伤程度,每周称量体质量,并对小鼠左耳拍照。
治疗期间,于每天同一时间段观察各组小鼠耳廓组织的肿胀度、炎症情况及丘疹等皮损情况,并且测量记录造模前后及治疗期间小鼠耳廓厚度,测量时固定选择左耳耳廓中同一位置进行测量,重复3次。
将4%多聚甲醛固定好的耳廓组织脱钙处理后,再进行脱水处理、石蜡包埋、切片、HE染色,显微镜下观察组织病理学改变。
使用组织研磨机将小鼠左耳皮肤组织用PBS缓冲液匀浆5 min,然后在4 ℃下以9 200 r·min-1离心10 min取其上清液进行测试。IFN-γ、IL-1β、IL-6的水平分别使用商业ELISA试剂盒根据制造商方案测定。另外使用BCA蛋白测定试剂盒对样品中的总蛋白进行定量测定。

收集白及相关的化学成分,以mol格式导入UNIFI 1.8软件以建立白及化学成分自建库,保留质量误差设定为(-5~5)×10-6,MS信号响应值>2 000的峰。根据化合物的一级和二级碎片的离子理论质量数和相对保留时间(RT)进行推导,并利用白及自建库检索,参考Pubchem、Chemical Book网站和相关文献对比完成白及不同萃取提取物的化学成分解析。
经过UPLC-Q-TOF-MS鉴定的BSE中的有效成分为潜在活性成分。利用SwissTargetPrediction[6](http://swisstargetprediction.ch)数据库(物种选择为“Homo sapiens”,probability大于0)检索符合条件化合物的靶点。然后借助Uniprot(https://www.uniprot.org/)数据库对靶点信息进行标准化处理,从而获得此部位活性成分的基因靶点。
利用GeneCards(https://www.genecards.org)、Drugbank(https://go.drugbank.com/)、OMIM(https://www.omim.org)、DisGeNet(https://www.disgenet.org)这4个数据库中检索关键词“acne”,搜索与痤疮相关的靶点,通过微生信在线分析平台将BSE活性成分靶点与痤疮相关靶点取交集,最终获得BSE治疗痤疮的潜在作用靶点。
将BSE化学成分共同靶点与痤疮疾病靶点导入Cytoscape 3.8.2,构建白及治疗痤疮的“成分-靶点-疾病”网络,计算网络拓扑参数,筛选出与疾病靶点相互作用的化学成分。
将“2.5.1”项中交集基因导入STRING数据库,得到PPI网络,导出相关数据并导入Cytoscape 3.8.2软件,利用cytoNCA插件对核心基因进行计算,根据degree筛选出白及治疗痤疮的核心靶点。
利用Metascape[7]平台分析其主要的生物学过程与代谢通路并进行GO分析和KEGG通路分析。
将网络药理学分析得到的核心靶点及核心成分进行分子对接技术进行验证。核心成分的二维靶点和核心靶点的三维结构分别通过PubChem数据库和RCSB PDB数据库获得,将受体蛋白导入PYMOL 2.4.1软件进行去水和去配体操作;将活性成分导入AutoDuckTools 1.5.6软件计算扭转键、加氢,并且进行分子对接操作,根据成分与靶点的最低结合能制作表格,用PYMOL 2.4.1对结合能最低的结合模式作图。
采用GraphPad Prism 8 统计软件进行数据分析;计量资料以均数±标准差表示;采用单因素方差分析(One-way ANOVA),以P<0.05或P<0.01表示两组差异具有统计学意义。
白及醇提物经过溶剂萃取法,合并各部位萃取液,干燥后得BSE 19.31 g(得率7.1%)、BSB 8.54 g(得率3.1%)和BSW 16.45 g(得率6.1%)。
用牛津杯法分别测定不同浓度的白及不同部位提取物对痤疮丙酸杆菌、表皮葡萄球菌、金黄色葡萄球菌的抑菌作用,见表1表1结果显示,BSE对痤疮丙酸杆菌、表皮金黄色球菌、金黄葡萄球菌3种痤疮致病菌表现出明显的抑菌能力,且其抑菌能力随浓度升高而增强;另外BSB、BSW对以上3种菌均无抑菌能力,说明白及醇提物发挥抑菌作用的成分主要存在BSE中。
微量稀释法测定BSE对痤疮丙酸杆菌、表皮葡萄球菌、金黄色葡萄球菌的MIC分别为2.34、2.34、4.69 mg·mL-1,MBC分别为4.69、9.38、18.76 mg·mL-1。综合结果可知,BSE对痤疮丙酸杆菌的抑菌和杀菌效果最佳。
造模给药期间,小鼠体质量均稳定上升,精神状态良好,无死亡情况。
空白对照组小鼠左耳薄且表面光滑,皮下毛细血管清晰可见,且毛囊口未见角质物堆积。模型组小鼠左耳红肿明显,耳廓组织增生肥厚,表面粗糙覆盖有大量角化物,皮下毛细血管不可见,毛囊口扩张可见丘疹和脓疱,停止造模后耳廓仍然持续红肿,并伴随着轻度的脱屑;空白溶质组小鼠左耳在涂抹空白溶质后表面脱屑现象有所减轻,其余情况无减轻;阳性组给药7 d后左耳组织红肿现象较模型组有明显减轻,表面呈淡粉色,且可见皮下毛细血管,未见耳廓表面角质物和丘疹出现;BSE给药组治疗后,耳廓表面光滑且红肿增厚消失,皮下毛细血管清晰可见,未见表面角质物、丘疹;BSB、BSW给药组治疗后,耳廓表面角质物减少,但其仍红肿增厚,左耳仍有丘疹存在。见图1
造模7 d后,与空白对照组对比,模型组小鼠左耳均明显红肿增厚,且表面有丘疹产生(P<0.01)。治疗7 d后,与模型组对比,阳性组和BSE给药组小鼠左耳耳廓厚度有明显下降(P<0.01,P<0.05);BSB、BSW给药组小鼠左耳耳廓厚度虽有轻微下降,但差异无统计学意义。见图1
小鼠耳廓组织HE染色结果显示,显微镜下可见空白对照组的耳廓组织角质层较薄,可见毛囊、皮脂腺体积正常,皮下未见炎症细胞浸润和毛细血管水肿,组织细胞无增殖;与空白对照组相比,模型组、空白溶质组角质层有明显增厚,且表皮组织结构被破坏,棘细胞层明显增厚,皮下炎性细胞明显浸润,毛细血管扩张、水肿、增生,局部区域炎症细胞增殖明显;阳性组和BSE给药组表皮角质增厚、炎症细胞浸润程度、毛细血管扩张程度均有明显减轻;BSB、BSW给药组的表皮角质组有轻微增厚,炎症细胞浸润程度较模型组仅有轻微减弱。见图2
与空白对照组相比,模型组小鼠组织中的IL-6、IL-1β含量显著升高,IFN-γ的含量显著下降(P<0.01);与模型组对比,阳性组、BSE给药组的IL-6、IL-1β含量显著下降,IFN-γ的含量显著升高(P<0.05),BSB、BSW给药组IL-6、IL-1β含量下降但是统计学无显著性差异,见表2
综上可知BSE抗痤疮效果最佳,可以有效抑制痤疮3种致病菌还可以降低痤疮小鼠耳廓肿胀度、改善耳廓的病理变化、显著降低组织中的炎症因子含量。

另外鉴定结果显示白及不同部位化学成分存在差异性成分。联苄类化合物及其菲类衍生物仅存在于乙酸乙酯部位中,糖苷类化合物在3个部位中均有分布,可推测芪类成分是白及发挥抗痤疮的药效活性成分。
糖苷类化合物是由糖或糖衍生物的端基碳原子与另一类非糖物质连接形成分化合物,主要是以糖苷键断裂为主。共鉴定出糖苷类成分14个。以保留时间13.13 min的化合物16为例,在负离子模式下的准分子离子峰为m/z 725.266 7[M-H]-,m/z 771.271 05[M+FA-H]-1个酯键断裂后即可产生特征碎片离子峰m/z 457.171 5[M-C13H17O6-H]-;如果两个酯键均断裂则产生天麻素基团m/z 285.097 9[M-C21H29O10-H]-和异丁基-苹果酸碎片 m/z 189.076 8[M-C26H33O12-H]-;另外碎片m/z 153.055 7[M-C26H36O14-H]-为源自异丁基-苹果酸碎片进一步裂解丢失2个H2O而得。可进一步推测化合物16为militarine,裂解规律与文献[8]报道相符,见图4
联苄类化合物是以1,2-二苯基乙烷作为母核的化合物,其苯环上的氢可以被多种取代基取代得到一系列的联苄类化合物,其主要的裂解方式取决于苯环之间的2个亚甲基碳连接断裂和苯环与亚甲基连接单键断裂[9],并且会随着苯环上取代基的不同而出现不同的裂解[10],共鉴定出12个联苄类化合物。以保留时间为22.7 min的化合物21为例,根据数据库推测其分子式为C15H16O3,在正离子模式下的准分子离子峰为m/z 245.116 8[M+H]-,亚甲基碳碳键断裂后形成了碎片离子峰m/z 151.075 55[M+H-C6H5O]-m/z 137.059 77[M+H-C7H7O]-m/z 107.048 98[M+H-C8H9O2]-m/z 121.064 76[M+H-C7H7O2]-,推测此化合物为batatasin Ⅲ,与文献[11]中报道一致,推测裂解途径见图5

联菲类化合物主要是以双菲中间连接的碳碳键断裂为主,以保留时间27.66 min的化合物30为例,准离子分子峰先脱去1分子-CH3,产生m/z 465.134 3 [M-CH3-H]-的碎片离子峰;进一步裂解断裂失去1个dihydrophenanthrene单元,形成了特征碎片离子峰m/z 223.040 7 [M-C16H19O3-H]-,确定此化合物为blestrianol A,推测裂解途径见图6
Dihydrophenanthrene化合物主要是以苯环之间的亚甲基碳碳键断裂以及亚甲基碳碳键断裂为主,以保留时间27.56 min的化合物29为例,在负离子模式下的准分子离子峰为m/z 347.129 9[M-H]-,失去-C6H5O形成特征碎片离子峰m/z 255.103 1[M-C6H5O-H]-;确定此化合物为1-(4-hydroxybenzyl)-4-methoxy-9,10-dihydropenanthrene-2,7-diol,推测裂解途径见图7
有机酸类化合物是植物中常见的一类天然产物,该类化合物的主要裂解途径为易丢失CH3、CO等支链基团,且易在羰基处断裂形成碎片离子。一共鉴定得到5个有机酸类化合物,以保留时间在8.99 min的化合物5为例,在负离子模式下的准分子离子峰为m/z 193.051 46[M-H]-,主要碎片离子峰有m/z 163.049 8[M-CH3O-H]-m/z 133.030 5[M-C2H5O2-H]-,对比文献[8]确定此化合物为ferulic acid,推测裂解途径见图8
筛选出满足以下2种条件的化学成分29个,条件1:5种类药性结果中有2个及2个以上为“Yes”的化合物,条件2:皮肤渗透性在±6 cm·s-1,筛选获得白及化学成分潜在作用靶点505个。基于4个疾病数据库得到2 120个痤疮相关靶点。将疾病靶点与药物靶点取交集,得到交集靶点153个,并制作韦恩图,见图9
将BSE化学成分与痤疮共同靶点基因导入Cytoscape 3.8.2,构建BSE治疗痤疮的“成分-靶点-疾病”网络,见图9。利用Network Analyzer工具计算网络拓扑参数,筛选出度值排名前8的化学成分作为核心活性成分,包括3-O-methylbatatasin Ⅲ、bulbocol、3,7-dihycroxy-2,4-dimethoyxphenanthrene-3-O-glucoside、3,3'-dihydroxy-2-(p-hydroxybenzyl)-5-methoxybibenzyl、3-(4-hydroxybenzyl)-4-methoxy-2,7-dihydroxy-9,10-dihydrophenanthrene、batatasin Ⅲ、4,7-dihydroxy-1-(p-hydroxybenzyl)-2-methoxy-9,10-dihydrophenanthrene,推测这些成分为BSE治疗痤疮的关键成分。
BSE治疗痤疮靶点蛋白的PPI网络见图9。按度值(degree)、介数中心性(betweenness centrality)、接近中心性(closenesscentrality)均大于其平均值进行筛选,见图9。其中排名前9的核心靶点分包括白蛋白(ALB)、丝氨酸/苏氨酸激酶 1(AKT1)、肿瘤坏死因子(TNF)、酪氨酸蛋白激酶(SRC)、雌激素受体1(ESR1)、表皮生长因子受体(EGFR)、雄激素受体(AR)、丝裂原活化蛋白激酶 1(MAPK1)和前列腺素内过氧化物合酶2(PTGS2)。
将BSE治疗痤疮相关靶点上传Metascape数据库平台进行信号通路分析。GO富集分析结果显示,生物过程主要涉及对激素的反应、调节激素水平、细胞对脂质的反应、炎症反应的调节、对细菌来源分子的反应、MAPK级联的调节等;细胞组成主要包括受体复合物、膜筏、细胞体、膜侧、转录调节因子复合物等;分子功能主要涉及蛋白激酶活性、核受体活性、类固醇结合、蛋白激酶结合、磷酸酶结合、MAP激酶活性等,选取q-value最小的前10条制图,见图9
KEGG通路分析得到163条通路(P<0.05),对前10条通路进行可视化处理,主要包括类固醇激素生物合成、卵巢类固醇生成、MAPK信号通路、Th17细胞分化、cAMP信号通路等。主要涉及与免疫炎症、激素合成相关的通路,如类固醇激素生物合成、卵巢类固醇生成、MAPK信号通路。
通过分子对接技术验证连接度排名前9的关键靶点与其对应并且度值排名前5的成分进行分子对接,当配体与受体蛋白的结合越稳定,其结合能越低,结合能见表4表4中的5个关键活性成分与关键靶点的结合稳定,可初步验证其为白及抗痤疮的关键药效物质。
白及自古以来就是美容良药,其既有苦寒清热之性,又有增白润肤之效,还可以收涩生肌。前期经过本草考证发现白及可以治疗面上面疮。现代研究表明,白及可以发挥美白、润肤、改善黄褐斑的疗效,但其在抗痤疮方面的活性和物质基础尚未有充分的阐述,本实验利用体外抗菌和痤疮小鼠模型筛选出白及有效抗痤疮的部位,结合UPLC-Q-TOF-MS技术明确白及各萃取部位中的化学成分,并且通过网络药理学及分子对接初步阐明了白及抗痤疮的关键药效成分,为进一步探索白及治疗痤疮的机制提供了重要的理论基础。
采用UPLC-Q-TOF-MS技术鉴定白及3个萃取部位,共鉴定出51个成分,其中联苄类及菲类成分仅在乙酸乙酯部位中检出,结合体外抑菌和小鼠复合模型实验结果可知芪类成分是其治疗痤疮的潜在活性成分。目前联苄化合物和菲系列衍生物已被发现具有显著抗菌活性[12-13],但乙酸乙酯部位中抑菌有效成分的含量较低,故导致其抑制痤疮致病菌的MIC较高,不过,与其他植物提取物相比[14-17],其对痤疮致病菌的抑制效果显著,具有深入研究的价值。因网络药理学可以从网络的角度解释药物成分、复杂疾病之间的相互作用关系,故采用网络药理学的方法,对芪类成分是其治疗痤疮的主要药效成分的结论作进一步验证的同时,还可以挖掘出白及治疗痤疮的核心活性成分、确定其作用的靶点。网络药理学及分子对接结果表明,山药素Ⅲ(batatasin Ⅲ)、3-(4-羟基苄基)-4-甲氧基-2,7-二羟基-9,10-dihydrophenanthrene[10-dihydrophenanthrene]、3,3'-二羟基-2-(对羟基苄基)-5-甲氧基联苄[3'-dihydroxy-2-(p-hydroxybenzyl)-5-methoxybibenzyl]、3-O-甲基山药素Ⅲ(3-O-methylbatatasin Ⅲ)是白及治疗痤疮的关键活性成分。目前,山药素Ⅲ已被证实具有广谱抗真菌能力[18];3,3'-二羟基-2-(对羟基苄基)-5-甲氧基联苄可以抑制痤疮丙酸杆菌细胞膜的增殖[19];山药素Ⅲ[20]和3-O-甲基山药素Ⅲ[21]可通过抑制p65核易位来调节下游炎性细胞因子的表达发挥抗炎作用。以上结果说明,白及中以山药素Ⅲ为代表的芪类成分是白及治疗痤疮的主要药效成分群。
目前认为主要造成痤疮发生有以下4种发病机制[22]:皮脂分泌过多、毛囊皮脂腺导管上皮角化异常、细菌感染及免疫炎症反应[23-25]。其中痤疮丙酸杆菌会促进多种炎症介质的释放[26],进而导致痤疮病程的延长和发展,因此除了抑菌,抑制炎症反应也是治疗痤疮中的一个重要环节。本实验建立复合痤疮小鼠模型以评估白及不同萃取部位对痤疮小鼠的疗效,结果显示,乙酸乙酯提取物能显著性改善痤疮引起的病理状态,且给药后小鼠耳廓组织中的IL-6、IL-1β水平下降,IFN-γ水平升高,说明其显著降低炎性因子释放。结合网络药理学分析结果进一步揭示白及可能通过AKT1、TNF、SRC、ESR1、EGFR、AR、MAPK1、PTGS2核心靶点发挥抗痤疮作用。其中AKT1、SRC、EGFR在皮肤细胞增殖、运动和分化中起着重要作用,影响皮肤细胞的功能。此外,ESR1[27]、AR[28]、PTGS2[29]、TNF[30]参与皮脂腺细胞的增殖、炎症等过程,进而加剧痤疮的发生。MAPK1[31]则参与多种细胞信号传导通路,调控炎症反应及细胞增殖。KEGG通路分析中,类固醇激素生物合成和卵巢类固醇生成[32]对激素平衡有直接影响,进而与痤疮的发病机制相关;MAPK[33]信号通路则通过调控细胞增殖和炎症反应,连接了多种靶点的作用;Th17通路[34]与介导免疫反应密切相关;而cAMP[35]信号通路则在调节细胞功能和代谢中起着重要作用。以上研究表明,白及治疗痤疮主要涉及激素合成、免疫炎症密切相关的信号通路。其可以通过抑制局部细菌感染和炎症、免疫反应两个方面治疗痤疮,这也体现中药通过多途径发挥药效的特点。
本实验采用的是小鼠复合模型,此模型可以模拟痤疮炎症的发病过程,但小鼠耳朵毛囊所含的细胞类型与人类毛囊情况并不相同[36],无法完全模拟人类痤疮中的黑头粉刺问题,故仍存在一定局限,白及治疗痤疮背后的确切机制还需要进一步深入研究,后续可结合多组学、分子动力学模拟等多种技术手段进一步验证。
