Abstract
OBJECTIVES To explore the mechanism of Anemarrhenae Rhizoma in treatment of Alzheimer's Disease (AD). METHODS The active ingredients and targets of Anemarrhenae Rhizoma for treatment of AD were screened with network pharmacology methods, the protein-protein interaction (PPI) network was constructed and the core targets were analyzed. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways enriching analysis was performed. The peripheral blood lymphocytes were extracted and lymphoblastoid cell lines (LCL) were constructed and an in vitro cell model of LCL-SKNMC was established. MTT and CCK-8 methods were used to quantify SKNMC/LCL cells, 2 ´, 7 ´-dichlorodihydrofluorescein diacetate (DCFH-DA) probe was used to detect reactive oxygen species (ROS), and immunofluorescence staining was used to detect the generation of Aβ1-42 in a co-cultured model. Western blotting was used to detect protein expression in the co-culture model. The lifespan of N2 nematodes was observed under oxidative stress, normal state, and heat stress; ROS generated by N2 nematodes was detected by DCFH-DA probes. The paralysis time of CL4176 N2 nematodes was evaluated by paralysis assay, and Aβ deposition in the pharynx was detected by Thioflavin S staining. RESULTS Through network pharmacology, 15 potential active ingredients and 103 drug-disease targets were identified. PPI analysis showed that the Anemarrhenae Rhizoma might play anti-AD roles through albumin, Akt1, tumor necrosis factor, epidermal growth factor receptor (EGFR), vascular endothelial growth factor A (VEGFA), mammalian target of rapamycin (mTOR), amyloid precursor protein (APP) and other related targets. KEGG analysis showed that the pharmacological effects of Anemarrhenae Rhizoma might involve the biological processes of Alzheimer's disease, endocrine resistance, insulin resistance; and neuroactive ligand-receptor interaction, phosphatidylinositol 3-kinase (PI3K)-Akt signaling pathway, calcium signaling pathway, AGE-RAGE signaling pathway in diabetes complications, neurotrophic factor signaling pathway and others. The in vitro cell experiments showed that Anemarrhenae Rhizoma was able to reduce the production of ROS and Aβ1-42 (both P<0.01), inhibit the expression of β-secretase 1 (BACE1), APP and Aβ1-42 proteins (all P<0.05), up-regulate the expression of p-PI3K/PI3K, p-AKT/AKT, p-GSK3β/GSK3β in SKNMC cells (all P<0.05). The in vivo studies further confirmed that Anemarrhenae Rhizoma prolonged the lifespan of C. elegans under stress and normal conditions, reduced the accumulation of ROS and the toxicity of Aβ deposition. CONCLUSIONS Anemarrhenae Rhizoma may reduce the production of Aβ in AD and inhibit its induced oxidative stress, which may be achieved by regulating the PI3K/Akt/GSK-3β pathway.

Discovering metabolic vulnerability using spatially resolved metabolomics for antitumor small molecule-drug conjugates development as a precise cancer therapy strategy. J Pharm Anal 2023; 13:776-787. [PMID: 37577390 PMCID: PMC10422108 DOI: 10.1016/j.jpha.2023.02.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 02/19/2023] [Accepted: 02/23/2023] [Indexed: 03/04/2023] Open
Abstract
Against tumor-dependent metabolic vulnerability is an attractive strategy for tumor-targeted therapy. However, metabolic inhibitors are limited by the drug resistance of cancerous cells due to their metabolic plasticity and heterogeneity. Herein, choline metabolism was discovered by spatially resolved metabolomics analysis as metabolic vulnerability which is highly active in different cancer types, and a choline-modified strategy for small molecule-drug conjugates (SMDCs) design was developed to fool tumor cells into indiscriminately taking in choline-modified chemotherapy drugs for targeted cancer therapy, instead of directly inhibiting choline metabolism. As a proof-of-concept, choline-modified SMDCs were designed, screened, and investigated for their druggability in vitro and in vivo. This strategy improved tumor targeting, preserved tumor inhibition and reduced toxicity of paclitaxel, through targeted drug delivery to tumor by highly expressed choline transporters, and site-specific release by carboxylesterase. This study expands the strategy of targeting metabolic vulnerability and provides new ideas of developing SMDCs for precise cancer therapy.

RSC Adv 2023; 13:11919-11928. [PMID: 37077258 PMCID: PMC10108379 DOI: 10.1039/d2ra07979h] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 04/04/2023] [Indexed: 04/21/2023] Open
Abstract
Processing is a traditional method for preparing decoctions of traditional Chinese medicine (TCM) that is imperative for reducing toxicity, increasing efficacy, and adjusting the properties of pharmacologically active components of the TCM. Salt processing of Anemarrhenae Rhizoma (AR), a traditional Chinese herb, has been employed since the Song dynasty and can enhance the ability of AR to enriching the Yin and downbearing fire according to the traditional theory recorded in the Enlightenment on Materia Medica. Previous research found that the hypoglycemic effect of AR was enhanced after salt processing, and the concentrations of three components, namely timosaponin AIII, timosaponin BIII, and mangiferin, all of which have hypoglycemic activities, have been found to be significantly increased after salt processing. In this study, we established an ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method to ultimately measure the concentrations of timosaponin AIII, timosaponin BIII, and mangiferin in rat plasma after administration of unprocessed AR and salt-processed AR (SAR) to the rats to further elucidate how salt processing affects the pharmacokinetic profiles of each of these compounds. Separation was achieved on an Acquity UPLC HSS T3 column. The 0.1% formic acid aqueous solution (v/v) and acetonitrile were used as the mobile phase system. Calibration curves of each compound in blank rat plasma, as well as the accuracy, precision, stability, and recovery of the total three analytes, were then measured to validate the method. The C max and AUC0-t values of timosaponin BIII and mangiferin in the SAR group were significantly higher than those of the AR group, while the T max values of timosaponin BIII and mangiferin in the SAR group were shorter than in the AR group. These results indicated that salt processing improved the absorption and bioavailability of timosaponin BIII and mangiferin in Anemarrhenae Rhizoma, and they provide a rationale for how the salt processing enhances the hypoglycemic effect of Anemarrhenae Rhizoma.

Integrated untargeted and targeted metabolomics to reveal therapeutic effect and mechanism of Alpiniae oxyphyllae fructus on Alzheimer's disease in APP/PS1 mice. Front Pharmacol 2023; 13:1104954. [PMID: 36712678 PMCID: PMC9873993 DOI: 10.3389/fphar.2022.1104954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Accepted: 12/30/2022] [Indexed: 01/12/2023] Open
Abstract
Introduction: Alpiniae oxyphyllae Fructus (AOF) has been abundantly utilized for the treatment of diarrhea, dyspepsia, kidney asthenia, and abdominal pain in China. AOF is effective for treating AD in clinical trials, but its exact mode of action is yet unknown. Methods: In this study, metabolomics was combined to ascertain the alterations in plasma metabolism in APP/PS1 transgenic mice, the therapy of AOF on model mice, and the dynamic variations in 15 bile acids (BAs) concentration. Results: 31 differential biomarkers were finally identified in APP/PS1 group vs. the WT group. The levels of 16 metabolites like sphinganine (Sa), lyso PE (20:2), lysoPC (17:0), glycocholic acid (GCA), deoxycholicacid (DCA) were increased in APP/PS1 group, and those of 15 metabolites like phytosphingosine, cer (d18:0/14:0), and fumaric acid were reduced in APP/PS1 group. After AOF treatment, 29 of the 31 differential metabolites showed a tendency to be back-regulated, and 15 metabolites were significantly back-regulated, including sphinganine (Sa), lyso PE (20:2), glycocholic acid (GCA), deoxycholic acid (DCA). The relationship between BAs level and AD had been received increasing attention in recent years, and we also found notable differences between DCA and GCA in different groups. Therefore, a BAs-targeted metabonomic way was established to determine the level of 15 bile acids in different groups. The consequence demonstrated that primary BAs (CA, CDCA) declined in APP/PS1 model mice. After 3 months of AOF administration, CA and CDCA levels showed an upward trend. Conjugated primary bile acids (TCA, GCA, TCDCA, GCDCA), and secondary bile acids (DCA, LCA, GDCA, TDCA, TLCA GLCA) ascended in APP/PS1 group. After 3 months of AOF treatment, the levels of most BAs decreased to varying degrees. Notably, the metabolic performance of DCA and GCA in different groups was consistent with the predictions of untargeted metabolomics, validating the correctness of untargeted metabolomics. Discussion: According to metabolic pathways of regulated metabolites, it was prompted that AOF ameliorated the symptom of AD mice probably by regulating bile acids metabolism. This study offers a solid foundation for further research into the AOF mechanism for the therapy of AD.
