In this study, two distinct diabetic models, namely spontaneous type 2 diabetic <em>db/db</em> mice and streptozotocin (STZ)-induced type 1 diabetic rats, were employed to assess the efficacy of YQYY in ameliorating DR. Ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was employed to identify the chemical composition of YQYY in mouse serum. Next, the possible targets and key pathways of YQYY for the management of DR were predicted by integrating network pharmacology and weighted gene co-expression network analysis (WGCNA). Network-based indicators were then employed to evaluate the efficacy of the formulae on DR, and molecular docking, along with compound similarity analysis, was used to identify candidate drugs of YQYY for DR. Finally, molecular biology techniques were utilized to experimentally validate the identified targets. Experimental results from animal models showed that YQYY effectively improved hemoglobin A1C (HbA1C), reduced vessel branch points, and mitigated retinal tissue injury in both DR models. 17 herbal components were identified in the YQYY-containing serum by UPLC-QTOF-MS. Network pharmacology predicted 44 common targets of YQYY involved in the regulation of DR. These targets were found to mainly participate in inflammation-related signaling pathways, including the NF-κB signaling pathway, toll-like receptor signaling pathway, IL-17 signaling pathway, and TNF signaling pathway. By integrating the most relevant disease templates for DR with network pharmacology, we preliminarily identified two key functions of YQYY and their associated regulatory targets, which showed strong connections and correlations with the targets identified in the screened DR disease models. These results demonstrate the pivotal role of core targets, such as BAX, BCL2, MMP9, SIRT1, PPARγ, VCAM1, PTGS2, TNF-α, and RELA, in mediating the therapeutic effects of YQYY in managing DR. Network analysis of YQYY efficacy in DR revealed a significant correlation between the YQYY targets and DR-related genes. Furthermore, molecular docking and drug similarity comparisons suggested that kaempferol, formononetin, and caffeic acid show potential as therapeutic candidates for DR.

In this work, a wide-screening approach is proposed to an individuation of transdermal bioactive components in herbal patches obtained by <em>Spatholobus suberectus</em> Dunn (<em>S. suberectus</em>). Using a two-dimensional microscale carbon fiber/active carbon fiber system combined with a quadrupole time-of-flight high-resolution mass spectrometry (2DµCFs-QTOF-HRMS), a rapid and comprehensive analysis, lasting only 5 min, allowed the identification of 45 distinct polar components within <em>S. suberectus</em> extracts.

The removal of carotenoids before HPLC-UV analysis has always been considered essential. However, this study demonstrates that this is unnecessary as the carotenoids do not interfere with the primary faradiol esters and the related compounds in the HPLC-UV chromatogram. Previously identified esters include the laurates, myristates and palmitates of faradiol and of three of its isomers (e.g., arnidiol, maniladiol and calenduladiol). This study tentatively identifies novel butyrates, caproates, caprylates, caprates, stearates, palmitoleates and oleates of faradiol and its isomers. These tentative identifications were performed using UHPLC coupled with triple quadrupole mass spectrometry (MS) through in-source fragments, product ion spectra (MS<sup>2</sup>) and parent ion spectra. Moreover, the product ion spectra of the faradiol isomers were compared. While similarities exist, some isomers were distinguishable.</div></div>","PeriodicalId":16685,"journal":{"name":"Journal of pharmaceutical and biomedical analysis","volume":"260 ","pages":"Article 116792"},"PeriodicalIF":3.1,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143687077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
