目的 基于盘龙七片“祛风除湿”抗炎功效,通过分析盘龙七片“功效成分群”在“饮片-成药-入血成分”间传递的动态规律,筛选出质量标志物(quality markers,Q-Marker)。方法 采用超高效液相-四极杆-飞行时间质谱联用技术(UPLC-Q-TOF-MS/MS)对盘龙七片化学成分群进行表征,根据前期网络药理学分析结果,筛选候选“功效成分群”并以多重反应监测(MRM)模式建立同时定量测定方法。进一步通过评估功效成分群在“饮片-成药-入血成分”间转移规律确定“功效成分群”组成,然后以虚拟分子对接技术筛选候选Q-Marker,最后以“成分-体外活性”关联算法分析候选Q-Marker与关键靶点的结合活性,确定能代表盘龙七片“祛风除湿”抗炎作用的Q-Marker。结果 成分表征鉴定并确定得到44个化学成分,结合网络药理学分析选择其中24个成分作为候选“功效成分群”。进一步评估“饮片-成药-入血”间动态传递规律筛选出7个转移率较高成分。最后通过分子对接及“成分-活性”关联算法确定了6个成分作为盘龙七片“祛风除湿”抗炎功效的Q-Marker。结论 综合盘龙七片化学成分表征、“饮片-成药-入血”间转移规律、关键靶点结合能力和体外活性关联分析结果,将去氢木香内酯、龙胆苦苷、木香烃内酯、β-蜕皮甾酮、迷迭香酸和染料木素6个化合物作为盘龙七片Q-Marker。

Objective To screen quality markers (Q-Marker) of Panlongqi Tablets (盘龙七片, PT) by analyzing the dynamic law of the transmission of its “functional component group” between “decoction piece-prescription medicine-blood component”, based on its anti-inflammation effects of “dispelling wind and dampness”. Methods The UPLC-QTOF-MS/MS technique was used to analyze the chemical constituents of PT, then according to our previous study of network pharmacologic analysis, the “functional component group” was pre-selected. After that, an MRM scan mode of UPLC-MS/MS was employed for the simultaneous quantitative methodology. Moreover, the “functional component group” was selected based on their dynamic transmission pattern in “decoction piece-prescription medicine-blood component”. Furthermore, the the virtual molecular docking technique was used to screen candidate Q-markers. Finally, the combination activity of candidate Q-markers and key targets was analyzed using the “compose-in vitro activity” association algorithm to identify Q-markers that can represent the anti-inflammatory effect of PT. Results A total of 44 components were characterized and identified. Aline with previously network pharmacologic prediction, 24 components were selected as candidate “functional component group”. After “decoction piece-prescription medicine-blood component” transmission analysis, seven components were screened with high transmission rate. Following the molecular docking and “compose-activity” regression calculation, six components were screened as the final Q-Marker that can represent the anti-inflammatory effect of “dispelling wind and dampness” of PT. Conclusion Based on the chemical composition characterization of PT, the transfer rule between “decoction piece-prescription medicine-blood component”, the binding ability of key targets and the correlation analysis results of in vitro activities, the dehydrocostus lactone, gentiopicroside, costunolide, β-ecdysone, rosmarinic acid and genistein were selected as Q-Marker of PT.
