Abstract
Ginseng is widely recognized for its diverse health benefits and serves as a functional food ingredient with global popularity. Ginsenosides with a broad range of pharmacological effects are the most crucial active ingredients in ginseng. This study aimed to derive ginseng glucosyl oleanolate (GGO) from ginsenoside Ro through enzymatic conversion and evaluate its impact on liver cancer in vitro and in vivo. GGO exhibited concentration-dependent HepG2 cell death and markedly inhibited cell proliferation via the MAPK signaling pathway. It also attenuated tumor growth in immunocompromised mice undergoing heterograft transplantation. Furthermore, GGO intervention caused a modulation of gut microbiota composition by specific bacterial populations, including Lactobacillus, Bacteroides, Clostridium, Enterococcus, etc., and ameliorated SCFA metabolism and colonic inflammation. These findings offer promising evidence for the potential use of GGO as a natural functional food ingredient in the prevention and treatment of cancer.

Anti-rheumatoid arthritis effects of total saponins from Rhizoma Panacis Majoris on adjuvant-induced arthritis in rats and rheumatoid arthritis fibroblast-like synoviocytes. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 119:155021. [PMID: 37603974 DOI: 10.1016/j.phymed.2023.155021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 07/24/2023] [Accepted: 08/09/2023] [Indexed: 08/23/2023]
Abstract
BACKGROUND Total saponins from Rhizoma Panacis Majoris (RPMTG) showed significant antitumour activity in our previous studies. Rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) with tumour-like characteristics have received attention as a therapeutic target for RA. However, the potential effect and mechanism of action of RPMTG against RA-FLS remain unclear. OBJECTIVE The study investigated the therapeutic effect of RPMTG on adjuvant-induced arthritis (AIA) in rats, and the regulation effect and underlying mechanism on apoptosis, autophagy of RA-FLS. METHODS The therapeutic effect of RPMTG was determined by the symptoms and signs of AIA rats. The production of inflammatory cytokines was detected by ELISA. Histopathological change of the ankle and synovial tissues were detected by HE staining. Flow cytometry, Hoechst 33342/PI staining, MDC staining, and TEM were used to determine the effects of RPMTG on apoptosis and autophagy. Western blotting was applied to detect the expression levels of proteins. RESULTS In AIA rats, RPMTG treatment ameliorated paw swelling, and arthritis score, restored synovial histopathological changes, inhibited the expression of IL-6 and IL-1β, exhibiting its potent anti-arthritis effect. In vitro, RPMTG depressed the proliferation of RA-FLS, arrested cell cycle in G0/G1 phase, and induced mitochondria-mediated apoptosis. Moreover, RPMTG significantly inhibited the autophagy in vivo and in vitro, proved by decreasing the expression of autophagy-related indicators (LC3II/LC3I, Beclin-1). Mechanistically, the study demonstrated that the activation of p38 MAPK and PI3K/Akt/mTOR pathways was mainly involved in the therapeutic effects of RPMTG. Interestingly, the effect of RPMTG on apoptosis was reversed after Rapamycin treatment, which preliminarily demonstrated that the inhibitory effect of RPMTG on autophagy was beneficial to the effect on inducing apoptosis. The regulation effect of RPMTG concurrently on apoptosis and autophagy revealed its unique advantages in RA treatment. CONCLUSION RPMTG showed potent therapeutic effects on AIA rats and induced apoptosis, inhibited autophagy mainly through activating the p38 MAPK and PI3K/Akt/mTOR pathways in RA-FLS.

Characterization of chikusetsusaponin IV and V induced apoptosis in HepG2 cancer cells. Mol Biol Rep 2022; 49:4247-4255. [PMID: 35212926 DOI: 10.1007/s11033-022-07259-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 02/10/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Chikusetsusaponin IV and V (CsIV and CsV), two typical oleanolic acid saponins, are mainly derived from the rhizome of Panax japonicus C.A. Mey. To reveal the anti-cancer effect of CsIV and CsV on liver cancer cells, human hepatic cancer cell lines (HepG2) were exposed to these saponins, and various physiological responses of HepG2 were investigated. METHODS AND RESULTS HepG2 cells were treated with CsIV, CsV and 5-fluorouracil (5-FU). Cell proliferation was measured by CCK-8 assay. The cell cycle arrest, cell apoptosis and intracellular Ca2+ levels were respectively identified by flow cytometry. The mitochondrial membrane potential was detected by fluorescence microscopy. And, the levels of apoptosis-related proteins were analyzed by western blotting. Both CsIV and CsV were demonstrated to inhibit cell viability, and induce cell cycle arrest and apoptosis of HepG2 in a dose-dependent manner. They also enhanced the intracellular Ca2+ level and decreased the mitochondrial membrane potential in HepG2 cells. Furthermore, p53 and p21 were found up-regulated in HepG2 cells treated by CsIV and CsV. The apoptotic proteins, bax, cytochrome c, cleaved caspase-3/-9, were all found activated in HepG2 cells after CsIV and CsV treatment. The anti-apoptotic protein, bcl-2, was significantly down-regulated in all treated HepG2 cells. CONCLUSION Our data demonstrated that CsIV and CsV exerted significant cytotoxic effects on HepG2 cells without affecting normal liver cells. And, these chikusetsusaponins, especially for CsIV, showed a potent effect on promoting cell apoptosis in HepG2 cells, which was associated with the activation of p53-mediated apoptosis pathway.

Abstract
Oleanolic acid (OA, 3 β - hydroxyoleanolic acid-12-en-28-oic acid) is a pentacyclic triterpenoid present in many plants. As a new framework for development of semi synthetic triterpenoids, OA is of great significance in the discovery of anticancer drugs. Some of these derivatives, such as CDDO (2-cyano-3,12-dioxooleana-1, 9 (11)-dien-28-oic acid) have been verified in clinical trials, while other derivatives studied previously, such as SZC014, SZC015 and SZC017 (OA derivatives respectively), are also candidate drugs for cancer treatment. This paper reviews the preclinical studies, literature evidence, target analysis and anticancer mechanism of OA and its derivatives. The mechanism of action of its derivatives mainly includes anti-cancer cell proliferation, inducing tumor cell apoptosis, inducing autophagy, regulating cell cycle regulatory proteins, inhibiting vascular endothelial growth, anti angiogenesis, inhibiting tumor cell migration and invasion. In recent years, the molecular mechanism of OA and its derivatives has been elucidated. These effects seem to be mediated by the alterations in a variety of signaling pathways induced by OA and its derivatives. In conclusion, OA and its derivatives are considered as important candidate drugs for the treatment of cancer, indicating that OA and its derivatives have the potential to be used as anticancer drugs in practice.

Abstract
Colorectal cancer (CRC) ranks third in incidence and second in mortality among all types of cancer, and due to its insidious onset and lack of early symptoms, it is usually diagnosed at a later stage. Saponins, a class of compounds abundant in plants, have been reported to possess prominent anti‑tumour properties. The use of ginsenoside Rg3 in the clinical setting was authorized by the National Medicinal Products Administration of China. In the present study, total saponins from Rhizoma Panacis Majoris (RPMTG) were prepared, and the pharmacological mechanisms underlying the anti‑CRC effects of RPMTG were investigated. The effect of RPMTG on the proliferation, cell cycle progression and apoptosis of HCT116 and SW620 cells were detected by MTT, flow cytometry and western blotting assays, and it was demonstrated that RPMTG could inhibit the proliferation of HCT116 and SW620 cells with IC50 values of 315.8 and 355.1 µg/ml, respectively, induce cell cycle arrest in the S and G0/G1 phase, and trigger apoptosis by downregulating the expression of the anti‑apoptotic proteins Bcl‑2, Bcl‑xL and induced myeloid leukaemia cell differentiation protein Mcl‑1, and increasing the expression of the pro‑apoptotic proteins Bax and Bad, cleaved caspased‑3 and poly(ADP)‑ribose polymerase. These findings suggested that RPMTG induced apoptosis through mitochondrial‑related pathways. In addition, RPMTG also decreased the expression of phosphorylated (p)‑extracellular signal‑regulated kinase and increased p‑c‑Jun N‑terminal kinase (p‑JNK) and p‑p38. Moreover, the effects of RPMTG on cell proliferation and apoptosis were partially reversed when the JNK and p38 mitogen‑activated protein kinase (MAPK) pathways were inhibited, indicating that RPMTG triggered apoptosis mainly via regulating JNK and p38 MAPK signalling. Therefore, RPMTG may have potential as an anti‑CRC agent, and further evaluations are needed.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Panacis majoris Rhizoma, which is a member of herbal medicine, is known for many years to remove blood stasis, promote blood circulation, and enrich the blood. The active ingredients of this plant are mainly attributed to saponins. AIM OF THE STUDY The total saponins from Panacis majoris Rhizoma (TSPJ), and the degradation products of TSPJ (DTSPJ), were designed in this study to compare the protective effects on myocardial ischemia-reperfusion injury, and the aim of this approach is to discover more effective agents for the treatment of ischemic heart diseases. We analyzed the main constituents of TSPJ and DTSPJ, aiming to make clear which saponins played important roles in this protective effect, and also investigated the possible mechanisms. MATERIALS AND METHODS DTSPJ was prepared by the method of alkaline hydrolysis. High performance liquid chromatography (HPLC) were used to analyze the main chemical constituents of TSPJ and DTSPJ, which were isolated by chromatographic techniques and identified by comparison with the Nuclear Magnetic Resonance (NMR) data in reported literature. Male Wistar rats were randomized to sham-operated group, ischemia-reperfusion group, three TSPJ (50, 100 and 200 mg/kg) groups, three DTSPJ (50, 100 and 200 mg/kg) groups, and isosorbide dinitrate tablet (5.0 mg/kg) group. The rats in all groups were intragastrically administrated once per day for three successive days. The establishment of the model of myocardial ischemia-reperfusion injury was used the following method: firstly, the left coronary artery of experimental rat was ligated for 30 min and then reperfused for 120 min. Then the myocardial infarct size, hemorheological and biochemical parameters, whole blood viscosity, plasma viscosity, platelet adhesion rate, platelet aggregation and histopathology changes were assessed. RESULTS Five C3,C28-bidesmosidic oleanane-type saponins and ginsenoside Rd were the main constituents of TSPJ, and their total content in TSPJ was 79.2 %. The main constituents of DTSPJ were five C3-monodesmosidic oleanane-type saponins and ginsenoside Rd, and their total content in DTSPJ was 72.6 %. The HPLC analysis revealed that the five C3,C28-bidesmosidic oleanane-type saponins in TSPJ were completely turned into five C3-monodesmosidic oleanane-type saponins in DTSPJ through the method of alkaline hydrolysis, but ginsenoside Rd remained unchanged. Both TSPJ and DTSPJ could significantly reduced myocardial infarct size, and improved heart function, and lowered the activities of aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and creatine kinase isoenzymes (CK-MB), and malonyldialdehyde (MDA) content, as well as the levels of whole blood viscosity, plasma viscosity, platelet adhesion rate, and platelet aggregation; on the contrary, both the level of glutathione peroxidase (GSH-Px) and the activity of superoxide dismutase (SOD) were notablely increased. The results of histopathological examination further supported the cardioprotective effects of TSPJ and DTSPJ. CONCLUSION Both TSPJ and DTSPJ can guard cardiomyocytes against myocardial ischemia-reperfusion injury. The underlying mechanisms may be closely related to its enhancing anti-oxidative properties, modifying blood viscosity, and inhibiting platelet aggregation and platelet adhesion. As a whole, the protection of DTSPJ against myocardial ischemia-reperfusion injury was a little stronger than those of TSPJ. The results display the prospect of DTSPJ as a drug candidate for treating ischemic heart disease.

Abstract
BACKGROUND Neuroinflammation plays a dominant role in the progression of postoperative cognitive dysfunction (POCD). This study was carried out to explore the neuroprotective effect of Chikusetsu saponin IVa (ChIV) against sevoflurane-induced neuroinflammation and cognitive impairment. METHODS The neuroprotective activity of ChIV against sevoflurane-induced cognitive dysfunction in aged rats was evaluated by Morris water maze, NOR test and Y-maze test, respectively. The expression of NLRP3, ASC and caspase-1, pro-inflammatory cytokines and apoptotic-related protein were detected in the hippocampus and primary neurons using western blot. TUNEL assay and immunohistochemistry staining were applied to assess the apoptotic cell and number of NLRP3-positive cells in the hippocampus. The oxiSelectIn Vitro ROS/RNS assay kit was used to detect the ROS level. The CCK-8 assay was applied to measure the viability of primary neurons. Flow cytometry was carried out to determine cell apoptosis. RESULTS Pretreatment with ChIV significantly alleviated neurological dysfunction in aged rat exposure to sevoflurane. Mechanistically, ChIV treatment significantly alleviated sevoflurane-induced apoptotic cell and neuroinflammation. Of note, the neuroprotective effect of ChIV against sevoflurane-induced neurotoxicity through blocking NLRP3/caspase-1 pathway. In consistent with in vivo studies, ChIV was also able to repress sevoflurane-induced apoptosis and neuroinflammation in primary neurons. Furthermore, pretreatment with NLRP3/caspase-1 pathway inhibitor (MCC950) significantly augmented the neuroprotective effect of ChIV. CONCLUSION Our finding confirmed that ChIV provides a neuroprotective effect against sevoflurane-induced neuroinflammation and cognitive impairment by blocking the NLRP3/caspase-1 pathway, which may be an effective strategy for the clinical treatment of elderly patients with POCD induced by anesthesia.

Abstract
The prostate cancer prognosis is still not fully understood. Chikusetsu saponin Iva (CHI), isolated from Aralia taibaiensis, shows anti-cancer and anti-inflammatory properties. Here, in our study, we attempted to explore the efficiency and the possible molecular mechanism by which CHI may suppress prostate cancer. CHI was found to inhibit prostate cancer cell proliferation and induce cell death without cytotoxicity in prostate normal cells. CHI resulted in intracellular reactive oxygen species (ROS) production, and induced apoptosis regulated by mitochondria in vitro studies. CHI-caused apoptosis was shown in both caspase-dependent and -independent manner, which released cyto-c, enhancing caspases expression and promoting apoptosis-inducing factors (AIF) as well as endonuclease G (Endo G) nuclear transfer, respectively. Moreover, in vivo study showed that prostate tumor was inhibited by CHI administration through apoptosis induction. Thus, the results illustrated that CHI might be an effective therapeutic strategy for prostate cancer treatment in future.
