The present study aimed to investigate potential inhibitors of fusion between HSV-1 and the cellular membrane of the host cell. Fusion and entry of HSV-1 into the host cell is mimicked by a virus-free eukaryotic cell culture system by co-expression of the HSV-1 glycoproteins gD, gH, gL, and gB in presence of a gD receptor, resulting in excessive membrane fusion and polykaryocyte formation. A microscopic read-out was used for the screening of potential inhibitors, whereas luminometric quantification of cell-cell fusion was used in a reporter fusion assay. HSV-1 gB was tagged at its C-terminus with mCherry to express mCherry-gB in both assay systems for the visualization of the polykaryocyte formation. Reporter protein expression of SEAP was regulated by a Tet-On 3 G system. The saponin mixture aescin was identified as the specific inhibitor (IC<sub>50</sub> 7.4 µM, CC<sub>50</sub> 24.3 µM, SI 3.3) of membrane fusion. A plaque reduction assay on Vero cells reduced HSV-1 entry into cells and HSV-1 cell-to-cell spread significantly; 15 µM aescin decreased relative plaque counts to 41%, and 10 µM aescin resulted in a residual plaque size of 11% (HSV-1 17 syn<sup>+</sup>) and 2% (HSV-1 ANG path). Release of the HSV-1 progeny virus was reduced by one log step in the presence of 15 µM aescin. Virus particle integrity was mainly unaffected. Analytical investigation of aescin by UHPLC-MS revealed aescin IA and -IB and isoaescin IA and -IB as the main compounds with different functional activities.

Here, we intended to assess the preclinical evidence of MLPs and explore their potenzial mechanisms on DKD, offering a scientific reference for the therapeutic use of MLPs. The study has been registered under the CRD42022309117 registration number at PROSPERO. Comprehensive search was conducted across eight databases from their establishment till January 2024, and eight studies with 270 animals were included in the meta-analysis. The primary outcome measurements in the MLP group, including serum creatinine (Scr) (P = 0.0005), blood urea nitrogen (BUN) (P = 0.02), 24-hour urinary protein (UP) (P = 0.001), and urinary microalbumin (UAlb) (P < 0.0001), were significantly reduced compared to the control group. Additionally, MLP treatment was significantly correlated with fasting blood glucose (FBG), total cholesterol (TC), protein expression of TGF-<i>β</i>1, CTGF mRNA, and the kidney index (all P values < 0.05) and delayed the progression of local pathological changes in the kidney. Subgroup analysis revealed significant species differences in the efficacy of MLPs. Also, it showed that the dosage of streptozotocin potenzially affected the Scr and UAlb results, while the duration of MLP treatment influenced UAlb results. MLPs may exert potenzial renal protection by delaying renal fibrosis, inhibiting inflammatory reactions, suppressing the growth hormone-insulin-like growth factor-insulin-like growth factor binding protein axis, and regulating the insulin receptor pathway. In summary, MLPs have multifaceted renal protective effects, suggesting their potenzial for treating DKD.</p>","PeriodicalId":20127,"journal":{"name":"Planta medica","volume":" ","pages":"1100-1114"},"PeriodicalIF":2.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11617037/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
