[Abstract] Objective To study the main active components and targets of Lycii Fructus by network pharmacology, and speculate the possible pharmacological mechanism. Methods The bioactive components of Lycii Fructus were searched on the platform of BATMAN-TCM. The bioactive components were screened according to the criteria of oral bioavailability (OB)≥30% and drug like (DL)≥0.18, and the corresponding targets of the bioactive components were found. The purpose protein interaction network of active ingredients of Lycii Fructus was constructed, and the GO function enrichment and KEGG signal pathway enrichment were performed using the DAVID database. Results Forty-five kinds of active components that were OB≥30%, DL≥0.18 in Lycii Fructus were screened, among which, 36 active components had a total of 208 targets eliminating duplicates. In the DAVID database, performed under the condition of “P < 0.05, number of genes>10”, and 56 GO items of main biological functions of Lycii Fructus were obtained, 84 KEGG pathways were obtained. Conclusion The exploration of the multi-functional substance basis and multi-dimensional pharmacological effects of Lycii Fructus can provide reference for the further study.

網(wǎng)絡(luò)藥理學(xué)是當(dāng)前中藥學(xué)科的研究前沿,其融合了系統(tǒng)生物學(xué)和多向藥理學(xué)思想,以構(gòu)建藥物-靶點(diǎn)-疾病之間的復(fù)雜網(wǎng)絡(luò)來分析藥物的作用機(jī)制,從而實(shí)現(xiàn)藥理研究由單一靶點(diǎn)轉(zhuǎn)向綜合網(wǎng)絡(luò)分析[1]。中藥具有多成分、多靶點(diǎn)、調(diào)節(jié)方式多樣的特點(diǎn),信息量極大[2]。網(wǎng)絡(luò)藥理學(xué)使中藥學(xué)研究從單靶標(biāo)、單成分研究思路開始向整體探究、系統(tǒng)調(diào)節(jié)轉(zhuǎn)變,從相互聯(lián)系的角度研究中藥藥理機(jī)制。
枸杞子(Lycii Fructus)是茄科多年生落葉灌木枸杞Lycium barbarum L.的干燥成熟果實(shí)。枸杞子性平,味甘,無毒,具有滋補(bǔ)肝腎、益精明目的功效,臨床上用來治療腰膝酸痛、內(nèi)熱消渴、頭暈、健忘等病癥[3-4]?,F(xiàn)代醫(yī)學(xué)證明,枸杞子具有抗氧化、抗衰老、增強(qiáng)免疫功能以及抗腫瘤等多種生物活性[5]。枸杞子活性成分多、作用靶點(diǎn)復(fù)雜,基于此,本研究利用網(wǎng)絡(luò)藥理學(xué)分析平臺(tái),對(duì)枸杞子的活性成分、其靶點(diǎn)相互作用關(guān)系進(jìn)行分析,為枸杞子藥理機(jī)制研究和臨床應(yīng)用提供更多可能。

1.1 枸杞子活性組分及靶點(diǎn)蛋白篩選
利用北京蛋白質(zhì)組研究中心開發(fā)的生物信息學(xué)工具BATMAN-TCM平臺(tái),以枸杞子為關(guān)鍵詞檢索活性成分,用類藥性(DL)和口服生物利用度(OB)兩個(gè)指標(biāo)進(jìn)行篩選[6],并且整理活性成分潛在靶點(diǎn)蛋白。
1.2 靶點(diǎn)蛋白互作(PPI)網(wǎng)絡(luò)構(gòu)建
為研究靶點(diǎn)蛋白整體作用水平,將篩選到的枸杞子活性成分相關(guān)靶點(diǎn)蛋白在STRING平臺(tái)在線構(gòu)建PPI模型[7-11]。
