TITLE: Identification of the chemical composition of Xiaoshi granules and study on its potential mechanism of the treatment of functional dyspepsia
摘要: 目的 对消食颗粒进行化学成分鉴定,并探讨其治疗功能性消化不良(FD)的潜在作用机制。方法首先采用超高效液相色谱串联四极杆飞行时间质谱对消食颗粒进行成分分析,再利用网络药理学方法筛选消食颗粒治疗FD的潜在作用靶点。利用AutoDockTools1.5.6软件对核心成分、靶点进行分子对接。结果从消食颗粒中共鉴定出53种主要化学成分,主要是黄酮类与有机酸类化合物。网络药理学筛选出槲皮素、异鼠李素、山柰酚、芦丁等核心成分与雌激素受体(ESR1)、信号转导与转录激活因子(STAT3)、雄激素受体(AR)、细胞肿瘤抗原(TP53)、乳腺癌组织中缺氧诱导因子1亚基α(HIF1A)、原癌基因酪氨酸蛋白激酶(SRC)6个核心靶点,获得磷脂酰肌醇3-激酶(PI3K)-蛋白激酶B(Akt)、晚期糖基化产物(AGE)-晚期糖基化终末产物受体(RAGE)、丝裂原活化蛋白激酶(MAPK)等主要信号通路。分子对接结果表明,核心成分与核心靶点间具有较好的对接活性。结论消食颗粒可能是通过槲皮素、异鼠李素、山柰酚等活性成分作用于STAT3、HIF1A、SRC等靶点,调节PI3K-Akt、AGE-RAGE、MAPK等信号通路,从而发挥其对FD的治疗作用。
ABSTRACT: OBJECTIVE To identify the chemical composition of Xiaoshi granules, and investigate its potential mechanism of action in the treatment of functional dyspepsia (FD). METHODS Firstly, ultra-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry was used to analyze the composition of the Xiaoshi granules, and then network pharmacology was used to screen the potential targets of the Xiaoshi granules for the treatment of FD. Molecular docking of core components and targets was performed by using AutoDock Tools 1.5.6 software. RESULTS A total of 53 major chemical components, mainly flavonoids and organic acids, were identified from Xiaoshi granules. Network pharmacology screened core components such as quercetin, isorhamnetin, kaempferol and rutin, six core targets such as estrogen receptor (ESR1), signal transducer and activator of transcription (STAT3), androgen receptor(AR), cellular tumor antigen (TP53), hypoxia-inducible factor 1 subunit α in breast cancer tissue(HIF1A), proto-oncogene tyrosine protein kinase (SRC), and obtained major signaling pathways such as phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt), advanced glycosylation products (AGE)-receptor for advanced glycosylation end products (RAGE), mitogen-activated protein kinase (MAPK). The molecular docking results showed good docking activity between the core components and the core targets. CONCLUSIONS Xiaoshi granules may act on STAT3, HIF1A, SRC and other targets through quercetin, isorhamnetin, kaempferol and other active ingredients to regulate PI3K- Akt, AGE-RAGE, MAPK and other signal pathways, thus exerting its therapeutic effect on FD.
