Liang CC, Zhang FQ, Chen J. Screening and characterization of cosmetic efficacy components of Terminalia chebula based on biological activity-guided methodology. Biomed Chromatogr 2024:e5974. [PMID: 39090681 DOI: 10.1002/bmc.5974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 07/02/2024] [Accepted: 07/17/2024] [Indexed: 08/04/2024]
Abstract
Terminalia chebula exhibits a high level of antioxidant capacity and is highly valued in medicine and cosmetics. However, its main efficacy and active ingredients related to antioxidant, whitening, and anti-aging are still unclear. In this study, the active site responsible for its cosmetic efficacy was specified by the biological activity-guided method and further characterized by using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS/MS). T. chebula was ultrasonically extracted by five solvents, and 30% ethanol extract was screened out for subsequent purification by 1,1-D-iphenyl-2-picrylhydrazyl radical (DPPH), 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulphonate) (ABTS), hydroxyl, and superoxide anion free radical scavenging assays. Five elution fractions were obtained by column chromatography on D101 macroporous adsorbent resin eluted by an increased proportion of ethanol. The 30% ethanol elution fraction was specified as the enrichment site of active ingredients showing good antioxidant capacity and potent inhibitory activity against tyrosinase and elastase. A total of 30 compounds were identified by UHPLC-QTOF-MS/MS in the 30% ethanol elution fraction, including 11 gallotannins, 14 ellagitannins, and 5 other compounds, and these compounds may be the key ingredients in cosmetics beneficial for the skin. Such a biological activity-guided method has provided a simple and rapid venue for specifying the components of medicinal herbs responsible for cosmetic efficacy.

Abstract
Plants have a history of being employed in managing breast cancer. However, no scientific evidence supports the idea that these plants can effectively reduce the level of HER2 expression. In this study, extracts from 10 medicinal plants were evaluated for their anticancer properties against HER2-positive breast cancer cells through various methods, including the SRB assay, comet assay, annexin V-FITC dual staining, and immunoblotting. All extracts exerted antiproliferative activity against HER2-positive breast cancer cells. Furthermore, Terminalia chebula (T. chebula), Berberis aristata (B. aristata), and Mucuna pruriens (M. pruriens) reduced HER2 expression in tested cell lines. In addition, an increased Bax/Bcl-2 ratio was observed after the treatment. A comparative proteomics study showed modulation in the proteome profile of breast cancer cells after treatment with T. chebula, B. aristata, Punica granatum, M. pruriens, and Acorus calamus. Metabolic profiling of lead plants revealed the existence of multiple anticancer compounds. Our study demonstrates the considerable potential of the mentioned plants as innovative therapies for HER2-positive breast cancer.

[PMID: 37678676 DOI: 10.1016/j.ijbiomac.2023.126720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 08/20/2023] [Accepted: 09/03/2023] [Indexed: 09/09/2023]
Abstract
Candida glabrata, the second most common cause of invasive fungal infections, exhibits multi-drug resistance to commonly used antifungal drugs. To counter this resistance, there is a critical need for novel antifungals. This study identifies small molecule inhibitors that target a three-helix bundle KIX domain in the Med15a Mediator subunit of Candida glabrata (CgMed15a KIX). This domain plays a crucial role by interacting with the Pleiotropic Drug Resistance transcription factor Pdr1, a key regulator of the multidrug resistance pathway in Candida glabrata. We performed high throughput computational screening of large chemical datasets against the binding sites of the CgMed15a KIX domain to identify novel inhibitors. We selected six potential candidates with high affinity and confirmed their binding with the CgMed15a KIX domain. A phytochemical compound, Chebulinic acid binds to the CgMed15a KIX domain with a KD value of 0.339 μM and shows significant inhibitory effects on the growth of Candida glabrata. Molecular dynamics simulation studies further revealed the structural stability of the CgMed15a KIX-Chebulinic acid complex. Thus, in conclusion, this study highlights Chebulinic acid as a novel potential antifungal compound against Candida glabrata.

Abstract
INTRODUCTION Although the Tibetan medicine Triphala (THL) is widely used in many countries, insufficient progress has been made in quality control. OBJECTIVES The present study aimed to propose a methodology for quality control of THL based on HPLC fingerprinting combined with an orthogonal array design. METHODS Seven identified peaks were used as indicators to examine the effects of temperature, extraction time, and solid-liquid ratio on the dissolution of active ingredients in THL. Fingerprint analysis was performed on 20 batches of THL from four geographical areas (China, Laos, Thailand, and Vietnam). For further chemometric assessment, analysis techniques including similarity analysis, hierarchical clustering analysis, principal component analysis, and orthogonal partial least squares discrimination analysis (OPLS-DA) were used to classify the 20 batches of samples. RESULTS Fingerprints were established and 19 common peaks were identified. The similarity of 20 batches of THL was more than 0.9 and the batches were divided into two clusters. Four differential components of THL were identified based on OPLS-DA, including chebulinic acid, chebulagic acid, and corilagin. The optimal extraction conditions were an extraction time of 30 min, a temperature of 90°C, and a solid-liquid ratio of 30 mL/g. CONCLUSION HPLC fingerprinting combined with an orthogonal array design could be used for comprehensive evaluation and quality assessment of THL, providing a theoretical basis for further development and utilization of THL.

Abstract
Over recent years, much attention has been devoted to the field of screening natural products and/or their novel structures because of reversing cancer progression. The current research work was intended to explore the cytotoxic activity of ethanol and ethyl acetate extracts of dried fruit of Terminalia chebula Retz. (T. chebula) in MCF-7 cell line. High-performance thin-layer chromatographic (HPTLC) method and Folin-Ciocalteu colorimetric techniques were performed. Anti-proliferative activities of T. chebula fruit extracts on the MCF-7 cell line were evaluated using MTT assay. Effects of both extracts on the migration of MCF-7 cells and the size of MCF-7-derived spheroids were also evaluated. Moreover, antioxidant properties were measured by DPPH and FRAP methods. Western blotting was used to measure the HIF-1α and CXCR-4 protein levels. Chebulagic acid, gallic acid, chebulinic acid, and ellagic acid were found as major compounds in both extracts. The total phenolic contents based on gallic acid equivalent (GAE) in the ethanol and ethyl acetate extracts of T. chebula were found to be 453.68 ± 0.31 and 495.12 ± 0.43 mg GAE/g dry weight of the extract, respectively. Both extracts exerted a significant dose- and time-dependent cytotoxicity effect on MCF-7 cells. They also had a marked negative effect on the average size of MCF-7-derived spheroids and their migration rate. None of the extracts exhibited stronger antioxidant activities than vitamin C. Furthermore, both extracts at a concentration of 125 µg/ml could meaningfully decrease the expression levels of HIF-1α and CXCR-4 in MCF-7 cells. These data represent that T. chebula may be a valuable medicinal resource in the regulation of breast cancer proliferation, growth, and metastasis.

Abstract
Terminalia chebula Retz, commonly known as 'Haritaki/Myrobalan,' has been utilised as a traditional medicine for a long time. It has been extensively exercised in various indigenous medicine practices like Unani, Tibb, Ayurveda, and Siddha to remedy human ailments such as bleeding, carminative, dysentery, liver tonic, digestive, antidiarrheal, analgesic, anthelmintic, antibacterial and helpful in skin disorders. Studies on the pharmacological effects of T. chebula and its phytoconstituents documented between January, 1996 and December, 2021 were explored using various electronic databases. During the time mentioned above, several laboratory approaches revealed the biological properties of T. chebula, including antioxidative, antiproliferative, anti-microbial, proapoptotic, anti-diabetic, anti-ageing, hepatoprotective, anti-inflammatory, and antiepileptic. It is also beneficial in glucose and lipid metabolism and prevents atherogenesis and endothelial dysfunction. Different parts of T. chebula such as fruits, seeds, galls, barks extracted with various solvent systems (aqueous, ethanol, methanol, chloroform, ethyl-acetate) revealed major bioactive compounds like chebulic acid, chebulinic acid, and chebulaginic acid, which in turn proved to have valuable pharmacological properties through broad scientific investigations. There is a common link between chebulagic acid and chebulanin with its antioxidant property, antiaging activity, antiinflammatory, antidiabetic activity, and cardioprotective activity. The actions may be through neutralizing the free radicals responsible for producing tissue damage alongside interconnecting many other diseases. The current review summarises the scientifically documented literature on pharmacological potentials and chemical compositions of T. chebula, which is expected to investigate further studies on this subject.

Abstract
OBJECTIVES Limited treatment options are available for advanced stages of chronic myeloid leukaemia (CML). Moreover, patients' relapse after a short remission period, which prompts them to identify a potent drug with the least toxicity. An Unani herbal formulation, Itrifal-e-Aftimoon (IEA) is used for certain neurological disorders, however, its antitumor potential has not been reported yet in any malignancy, including CML. METHODS The aqueous extract of IEA was characterized by HPLC/LC-MS and used alone or in combination with standard drug, imatinib in CML cell lines (K562, KU812) in vitro to assess its effect on cancer-associated parameters such as cytotoxicity, cell cycle, apoptosis, oxidative stress, inflammation, angiogenesis, and certain signalling pathways. RESULTS LC-MS characterization of IEA showed the presence of antitumor compounds including catechin and caffeic acid. Treatment with IEA caused cytotoxicity and arrested cells in the sub-G0/G1 phase. Subsequent assays confirmed apoptosis-mediated cell death with mitochondrial membrane depolarization and alleviation of oxidative stress. IEA abrogates IL-6, VEGF, angiopoietin-2, and alters Th1/Th2 cytokines. IEA potentiated the effect of imatinib even at lower doses by affecting FAK/STAT/Akt/ERK pathways. CONCLUSION IEA possesses antitumor potential against CML and increases the efficacy of imatinib when used in combination, suggesting utilization of IEA as an adjuvant therapy for better management of CML in the future.

Abstract
Maintaining quality of life with an increase in life expectancy is considered one of the global problems of our time. This review explores the possibility of using natural plant compounds with antioxidant, anti-inflammatory, anti-glycation, and anti-neurodegenerative properties to slow down the onset of age-related changes. Age-related changes such as a decrease in mental abilities, the development of inflammatory processes, and increased risk of developing type 2 diabetes have a significant impact on maintaining quality of life. Herbal preparations can play an essential role in preventing and treating neurodegenerative diseases that accompany age-related changes, including Alzheimer’s and Parkinson’s diseases. Medicinal plants have known sedative, muscle relaxant, neuroprotective, nootropic, and antiparkinsonian properties. The secondary metabolites, mainly polyphenolic compounds, are valuable substances for the development of new anti-inflammatory and hypoglycemic agents. Understanding how mixtures of plants and their biologically active substances work together to achieve a specific biological effect can help develop targeted drugs to prevent diseases associated with aging and age-related changes. Understanding the mechanisms of the biological activity of plant complexes and mixtures determines the prospects for using metabolomic and biochemical methods to prolong active longevity.

Abstract
Defective protein folding and accumulation of misfolded proteins is associated with neurodegenerative, cardiovascular, secretory, and metabolic disorders. Efforts are being made to identify small-molecule modulators or structural-correctors for conformationally destabilized proteins implicated in various protein aggregation diseases. Using a metastable-reporter-based primary screen, we evaluated pharmacological chaperone activity of a diverse class of natural products. We found that a flavonoid glycoside (C-10, chrysoeriol-7-O-β-D-glucopyranoside) stabilizes metastable proteins, prevents its aggregation, and remodels the oligomers into protease-sensitive species. Data was corroborated with additional secondary screen with disease-specific pathogenic protein. In vitro and cell-based experiments showed that C-10 inhibits α-synuclein aggregation which is implicated in synucleinopathies-related neurodegeneration. C-10 interferes in its structural transition into β-sheeted fibrils and mitigates α-synuclein aggregation-associated cytotoxic effects. Computational modeling suggests that C-10 binds to unique sites in α-synuclein which may interfere in its aggregation amplification. These findings open an avenue for comprehensive SAR development for flavonoid glycosides as pharmacological chaperones for metastable and aggregation-prone proteins implicated in protein conformational diseases.

Abstract
Chebulinic acid (CA) is an ellagitannins isolated from the dried fruits of Terminalia chebula with diverse pharmacological activities. The present study focused on the acute toxicity of CA in normal Sprague Dawley (SD) rats. CA was administered via oral gavage to different groups in 300 and 2000 mg/kg body weight and vehicle respectively. All the animals were monitored carefully for any physiological or behavioral changes for 14 days. On day 15th animals were euthanized and blood was collected for hematological and biochemical analysis. Different tissues were collected for histopathological study using four different staining techniques (hematoxylin and eosin, Masson's trichrome, periodic acid Schiff and picro sirius red) to observe any pathological alterations. The results highlighted no morbidity and mortality after oral ingestion of CA (300 and 2000 mg/kg). Food and water consumption, body weight, relative organ weight, hematological and biochemical parameters were normal without any gross pathological lesions in harvested tissues. The outcome of the current study supported safety of CA even at high dose. However, further detailed study is required on experimentally disease model to unfold its therapeutic potential in laboratory animals.

Abstract
OBJECTIVES Tannins with complex structures are important plant resources, which are abundant in the genus Terminalia. Various Terminalia species have been playing an important role in traditional medicine system. A systematic scoping review of Terminalia Linn. research literature for tannins was conducted to summarize the structures of tannins and analysis fragmentation pathway characteristics, which could provide references for the structural analysis of tannins from Terminalia Linn. METHODS After an update of the literature search up to September 2018, the terms of Terminalia in all publications were analyzed. Electronic searches were conducted in scifinder and PubMed, and the information from 197 articles in all with regard to the tannin structure study was extracted. RESULTS The compounds of 82 tannins from the genus Terminalia were reviewed. According to the structural differences, they can be divided into three categories, hydrolysable tannins, condensed tannins, and complex tannins, respectively. The fragmentation pathways of 46 identified tannins were analyzed, and the fragmentation rules of tannins were speculated according to different types. CONCLUSION This review has attracted attention to the active substances in this species such as the tannins summarized in further study. How to improve the extraction and purification technology of tannins from genus Terminalia is an urgent problem to be solved.

Abstract
The purpose of the research is to study the development of response surface methodology for optimization of chebulinic acid extraction from composition of medicinal herbs such as Terminalia chebula, Phyllanthus emblica and seeds of Dimocarpus longan. Optimization of extraction parameters such as weight dosages, pH and time were carried out by response surface methodology (RSM). The optimal conditions determined for extraction of chebulinic acid through response surface methodology were dosage (6.25 g), pH (5.7) and time (24.23 h). These results showed that the developed model is satisfactory and relevant for the extraction of chebulinic acid. The analysis of variance showed a high goodness of model fit and the performance of the RSM method for improving chebulinic acid extraction from the composition of medicinal herbs. Quantitative estimation of chebulinic acid in the composition of medicinal herbs by HPLC studies revealed that 0.712% w/w of chebulinic acid content was present in the composition of herbal powder.

Bioorg Med Chem Lett 2017; 28:249-253.

Abstract
Glutamate-induced excitotoxicity and oxidative stress is a major causative factor in neuronal cell death in acute brain injuries and chronic neurodegenerative diseases. The prevention of oxidative stress is a potential therapeutic strategy. Therefore, in the present study, we aimed to examine a potential therapeutic agent and its protective mechanism against glutamate-mediated cell death. We first found that chebulinic acid isolated from extracts of the fruit of Terminalia chebula prevented glutamate-induced HT22 cell death. Chebulinic acid significantly reduced intracellular reactive oxygen species (ROS) production and Ca2+ influx induced by glutamate. We further demonstrated that chebulinic acid significantly decreased the phosphorylation of mitogen-activated protein kinases (MAPKs), including ERK1/2, JNK, and p38, as well as inhibiting pro-apoptotic Bax and increasing anti-apoptotic Bcl-2 protein expression. Moreover, we demonstrated that chebulinic acid significantly reduced the apoptosis induced by glutamate in HT22 cells. In conclusion, our results in this study suggest that chebulinic acid is a potent protectant against glutamate-induced neuronal cell death via inhibiting ROS production, Ca2+ influx, and phosphorylation of MAPKs, as well as reducing the ratio of Bax to Bcl-2, which contribute to oxidative stress-mediated neuronal cell death.
