Abstract
Two undescribed protostane triterpenoids, 11-deoxy-13(17),15-dehydro-alisol B 23-acetate (2) and alisol S (3), together with 21 known ones (1, 4-23), were isolated from the dried rhizome of Alisma plantago-aquatica. Of these compounds, 13(17),15-Dehydro-alisol B 23-acetate (1) and 11-deoxy-13(17),15-dehydro-alisol B 23-acetate (2) are two protostane triterpenoids containing conjugated double bonds in the five-membered ring D that are rarely found from nature resource, while alisol S (3) is a protostane triterpenoid with undescribed tetrahydrofuran moiety linked via C20 -O-C24 at the side chain. Additionally, compound 18 is a new natural product, and cycloartenol triterpenoid 23 is a non protostane triterpenoid firstly isolated from genus Alisma. Their structures were elucidated by extensive spectral analysis of the UV, IR, MS, 1D and 2D NMR, and comparison of the experimental and calculated CD curves.

Abstract
More than 100 protostane triterpenoids have been isolated from the dried rhizomes of Alisma species, designated Alismatis rhizoma (AR), commonly used in Asian traditional medicine to treat inflammatory and vascular diseases. The main products are the alisols, with the lead compounds alisol-A/-B and their acetate derivatives being the most abundant products in the plant and the best-known bioactive products. The pharmacological effects of Ali-A, Ali-A 24-acetate, Ali-B, Ali-B 23-acetate, and derivatives have been analyzed to provide an overview of the medicinal properties, signaling pathways, and molecular targets at the origin of those activities. Diverse protein targets have been proposed for these natural products, including the farnesoid X receptor, soluble epoxide hydrolase, and other enzymes (AMPK, HCE-2) and functional proteins (YAP, LXR) at the origin of the anti-atherosclerosis, anti-inflammatory, antioxidant, anti-fibrotic, and anti-proliferative activities. Activities were classified in two groups. The lipid-lowering and anti-atherosclerosis effects benefit from robust in vitro and in vivo data (group 1). The anticancer effects of alisols have been largely reported, but, essentially, studies using tumor cell lines and solid in vivo data are lacking (group 2). The survey shed light on the pharmacological properties of alisol triterpenoids frequently found in traditional phytomedicines.

Abstract
Lipase inhibitors are an attractive class of hypolipidemic compounds, which inhibit the activity of human pancreatic lipase, thereby preventing the absorption of triglycerides in vivo. As a library of promising lead compounds for drug development, traditional Chinese medicine (TCM) has gained growing attention in quick discovery and identification of enzyme inhibitors of natural-origin. The purpose of this work was to discover unknown lipase inhibitors from Alisma orientale by the activity oriented analysis method thin-layer chromatography-bioautography, then use electrospray ionization mass spectrometry technology via the elution based TLC-MS interface to identify their structures. As a result, eleven natural lipase inhibitors from Alisma orientale extracts were identified based on molecular mass and fragment ions obtained by HPTLC-MS, and further confirmed by a series of complementary means including UV spectra, 1H NMR characteristic proton signals and polarity of compounds, eleven lipase inhibitors were tentatively assigned as triterpenoids: alisol B (m/z 495.50 [M + Na]+), alisol B 23-acetate (m/z 537.58 [M + Na]+), 11-deoxy-alisol B (m/z 479.50 [M + Na]+), 11-deoxy-alisol B 23-acetate (m/z 521.50 [M + Na]+), alisol A/epialisol A (m/z 513.50 [M + Na]+), 16-oxo-11-deoxy-alisol A (m/z 511.50 [M + Na]+), 16-oxo-alisol A (527.50 [M + Na] +), alisol C (m/z 509.58 [M + Na]+), alisol C 23-acetate (m/z 551.50 [M + Na]+), alisol M 23-acetate (m/z 567.50 [M + Na]+), and alismanol Q/neoalisol (m/z 493.42 [M + Na]+). The integrated approach is an efficient method for rapid screening lipase inhibitors from complex plant extracts and provides a reasonable and favorable basis for the identification and separation of other enzymatic system and other important compounds with therapeutic values.

Alisol A 24-acetate ameliorates nonalcoholic steatohepatitis by inhibiting oxidative stress and stimulating autophagy through the AMPK/mTOR pathway. Chem Biol Interact 2018; 291:111-119.

Abstract
Alisol A 24-acetate (AA), a natural triterpenoid isolated from the traditional Chinese medicine Rhizoma Alismatis, has various therapeutic effects. We investigated the anti-nonalcoholic steatohepatitis (NASH) effect of AA and its underlying mechanisms in vitro and in vivo. C57BL/6 mice were fed a methionine and choline-deficient (MCD) diet for 4 weeks to induce NASH. The mice were simultaneously treated with a daily dose of AA (15, 30, and 60 mg kg-1, ig) for 4 weeks. On the last day, the animals were sacrificed and plasma and liver tissue were collected. Serum and liver tissue biochemical analyses and histological observation were performed. The human hepatic stellate cell line LX-2 was used to build NASH models by culturing with conditioned medium from WRL-68 liver cells after exposure to MCD medium in vitro. Liver oxidative stress and inflammatory indices and autophagy markers were examined. The results showed that AA suppressed reactive oxygen species (ROS) and inflammation in a NASH mouse model and inhibited the expression of inflammatory cytokines and ROS in LX-2 cells in MCD medium. Furthermore, we found AA stimulated autophagy in mice liver and LX-2, which could be the underlying mechanism of AA in NASH. To further investigate the role of autophagy in LX-2 cells, we found that AA regulated autophagy via the AMPK/mTOR/ULK1 pathway and dorsomorphin, a selective AMPK inhibitor, led to the suppression of AA-induced autophagy. Taken together, our results indicate that AA could be a possible therapy for NASH by inhibiting oxidative stress and stimulating autophagy.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2018; 45:93-104. [PMID: 29705003 DOI: 10.1016/j.phymed.2018.04.006] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2017] [Revised: 03/02/2018] [Accepted: 04/02/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND Quality control of traditional Chinese medicines is currently a great concern, due to the correlation between the quality control indicators and clinic effect is often questionable. According to the "multi-components and multi-targets" property of TCMs, a new special quality and bioactivity evaluation system is urgently needed. PURPOSE Present study adopted an integrated approach to provide new insights relating to uncover quality marker underlying the effects of Alisma orientale (AO) on lipid metabolism. METHODS In this paper, guided by the concept of the quality marker (Q-marker), an integrated strategies "effect-compound-target-fingerprint" was established to discovery and screen the potential quality marker of AO based on network pharmacology and chemical analysis. Firstly, a bioactivity evaluation was performed to screen the main active fractions. Then the chemical compositions were rapidly identified by chemical analysis. Next, networks were constructed to illuminate the interactions between these component and their targets for lipid metabolism, and the potential Q-marker of AO was initially screened. Finally, the activity of the Q-markers was validated in vitro. RESULTS 50% ethanol extract fraction was found to have the strongest lipid-lowering activity. Then, the network pharmacology was used to clarify the unique relationship between the Q-markers and their integral pharmacological action. CONCLUSION Combined with the results obtained, five active ingredients in the 50% ethanol extract fraction were given special considerations to be representative Q-markers: Alisol A, Alisol B, Alisol A 23-acetate, Alisol B 23-acetate and Alisol A 24-acetate, respectively. The chromatographic fingerprints based Q-marker was establishment. The integrated Q-marker screen may offer an alternative quality assessment of herbal medicines.

Abstract
Abstract
To develop new whitening agents from natural products, we screened 80 compounds derived from crude drugs in Kampo medicine in a melanin synthesis inhibition assay using murine B16 melanoma cells. The screen revealed that treatment with alisol B, a triterpene from Alismatis rhizoma, significantly decreased both melanin content and cellular tyrosinase activity in B16 cells. However, alisol B did not directly inhibit mushroom tyrosinase activity in vitro. Therefore, we investigated the mechanism underlying the inhibitory effect of alisol B on melanogenesis. Alisol B suppressed mRNA induction of tyrosinase and its transcription factor, microphthalmia-associated transcription factor (MITF). Furthermore, alisol B reduced the phosphorylation of CREB and maintained the activation of ERK1/2. These results suggest that the reduction in melanin production by alisol B is due to the downregulation of MITF through the suppression of CREB and activation of ERK and that alisol B may be useful as a new whitening agent.

Abstract
Alisma orientale (Sam.) Juzep. (Alismataceae) is a traditional and famous Chinese medicinal herb. Its rhizomes, which possess versatile bioactivities, are commonly used to treat oliguria, edema, gonorrhea with turbid urine, leukorrhea, diarrhea and dizziness. Approximately 120 compounds have been isolated from A. orientale. Terpenoids have been identified as A. orientale's characteristic constituents, which include protostane triterpenoids and guaiane sesquiterpenoids. The traditional medical uses of A. orientale in TCM have been evaluated in modern pharmacological studies, which have shown that A. orientale and its active constituents exhibit a wide range of bioactivities, such as diuretic, anti-urolithiatic, antinephritic, anti-atherosclerotic, immunomodulatory, and hepatoprotective activities. The medicinal potential of A. orientale makes it an ideal candidate for new drug development. Further studies are still required to identify its bioactive constituents, and elucidate the structure-activity relationship and detailed mechanisms of action. Additionally, the use of the other medicinal parts of A. orientale may reduce resource waste and afford novel secondary metabolites.

Simultaneous determination of three triterpenes in rat plasma by LC-MS/MS and its application to a pharmacokinetic study of Rhizoma Alismatis extract. J Chromatogr B Analyt Technol Biomed Life Sci 2015; 1008:32-37. [PMID: 26613538 DOI: 10.1016/j.jchromb.2015.11.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2015] [Revised: 11/02/2015] [Accepted: 11/08/2015] [Indexed: 11/16/2022]
Abstract
We have developed a sensitive and specific LC-MS/MS method for the simultaneous determination of alisol A (A), alisol A 23-acetate (A23) and alisol A 24-acetate (A24), the major active components in Rhizoma Alismatis extract (RAE), in rat plasma. In brief, plasma samples were extracted by methyl tert-butyl ether and chromatographically separated by using a C18 column. A tandem mass spectrometric detection with an electrospray ionization (ESI) interface was conducted via multiple reaction monitoring (MRM) under positive ionization mode. This method was validated for specificity, linearity, accuracy (within ±15.4%), intra- and inter-day precision (CV<11.4%) over the concentration range of 25-5000ng/mL for A, and 5-1000ng/mL for both A23 and A24. The significantly lower detection limit was determined as 25ng/mL for A, 5ng/mL for A23 and A24. This validated method of ours was then used to study the pharmacokinetics of RAE in rat. The elimination half-lives (t1/2) of A, A23 and A24 was determined as 0.75, 0.83 and 0.82h respectively after intravenous injection, and the oral absolute bioavailability of A, A23 and A24 was 43.1±18.1%, 6.3±1.5% and 7.9±1.2%. This new determination method of us for alisols is proven to very useful to study the pharmacological activities of RAE in future.

Abstract
Twelve new and 10 known protostane triterpenoids were isolated from the rhizome of Alisma orientale. Their structures were elucidated based on physical data analyses, including UV, HRESIMS, NMR experiments ((1)H, (13)C NMR, (1)H-(1)H COSY, HSQC, HMBC, and NOESY), and induced electronic circular dichroism. New compounds 1-12 were classified as protostanes (1-10), 29-norprotostane (11), and 24-norprotostane (12) by structure analyses. Furthermore, the inhibitory effects on human carboxylesterases (hCE-1, hCE-2) of compounds 1-22 were evaluated. Compounds 2, 6, 9, and 11 showed moderate inhibitory activities and were selective toward hCE-2 enzymes, with IC50 values of 8.68, 4.72, 4.58, and 2.02 μM, respectively. The inhibition kinetics of compound 11 toward hCE-2 were established, and the Ki value was determined as 1.76 μM using a mixed inhibition model. The interaction of bioactive compound 11 with hCE-2 was shown using molecular docking.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhizoma alismatis (simplified as RA, "Zexie" in Chinese, ) is a well-known natural medicine with long history in Chinese medicine. As a traditional medicine in China, RA is an important part of many prescriptions and has been commonly used for treating a wide range of ailments related to dysuria, edema, nephropathy, hyperlipidaemia, diabetes, inflammation as well as tumor in clinical applications. Based on scientific literatures, the present paper aims to provide comprehensive and up-to date information about the traditional uses, phytochemistry, pharmacology, toxicology and quality control of RA as well as critical analysis of the research. The review will provide a new foundation and direction for the further studies of RA. MATERIALS AND METHODS All available information about RA was supplied by library database and electronic search (ScienceDirect, Web of Science, Pubmed, Google Scholar, etc.). The different types of useful information were collected and arranged in corresponding part of the paper. RESULTS Phytochemical studies showed that the main chemical composition of RA was the terpenoid including sesquiterpene, diterpene and triterpene. The crude extracts and isolated compounds from RA showed diverse pharmacological activities including diuretic, nephroprotective, anti-hyperlipidemic, anti-atherosclerotic, anti-cancer, anti-inflammatory and anti-oxidative activities. However, high-dose or long-term use of RA can lead to water-electrolyte imbalance, bloody urine, acidosis and even hepatotoxicity or nephrotoxicity, which have been proven by several studies. CONCLUSIONS Pharmacological researches show RA possessing various bioactivities including diuresis, nephroprotective effect, anti-hyperlipidemia, etc. However, more bioactive components especially diuretic and nephroprotective compounds need to be isolated and identified, and more rigorous researches on action mechanisms are required. More experiments in vitro or in vivo and clinical studies are encouraged to clarify correlation between traditional uses and modern applications, and the toxicity need to be further and precisely explored. In addition, a standardized fingerprint for RA is indispensable and emergent. These achievements will further expand to therapeutic potential and usage of RA and provide a powerful support for clinical use.

Abstract
Alismatis Rhizoma has been used in East Asia as a traditional treatment for various illnesses and symptoms, and the presence of protostane-type triterpenes has been claimed to provide health benefits. To investigate the subchronic toxicity of triterpene-enriched extract from Alismatis Rhizoma (TEAR), a 90-day oral toxicity study was conducted in rats. Sprague-Dawley rats were randomly divided into four groups (10 rats/sex/group) and received doses of 0, 360, 720, and 1440 mg/kg/d of TEAR for 90 days. Daily clinical observations as well as weekly measurement of body weight and food consumption were conducted. Blood samples were obtained on day 91 to measure changes in hematology and biochemistry. Urine samples were collected on days 0 and 91 for urinalysis. At necropsy, selected organs were weighed and recorded, and histological examination was performed. No mortality or obvious treatment-related clinical signs, hematology, urinalysis parameters, and macroscopic or microscopic examinations were observed. Differences in weight gain, food consumption, biochemistry, and relative organ weight between the treated group and the control group were not considered treatment-related. On the basis of these findings, the no-observed-adverse-effect level for TEAR was 1440 mg/kg/d in both sexes.

Abstract
Protostane triterpenes belong to a group of tetracyclic triterpene that exhibit unique structural characteristics. Their natural distribution is primarily limited to the genus Alisma of the Alismataceae family, but they have also been occasionally found in other plant genera such as Lobelia, Garcinia, and Leucas. To date, there are 59 known protostane structures. Many of them have been reported to possess biological properties such as improving lipotropism, hepatoprotection, anti-viral activity against hepatitis B and HIV-I virus, anti-cancer activity, as well as reversal of multidrug resistance in cancer cells. On the other hand, fusidanes are fungal products characterized by 29-nor protostane structures. They possess antibiotic properties against staphylococci, including the methicillin-resistant Staphylococcus aureus (MRSA). Fusidic acid is a representative member which has found clinical applications. This review covers plant sources of the protostanes, their structure elucidation, characteristic structural and spectral properties, as well as biological activities. The fungal sources, structural features, biological activities of fusidanes are also covered in this review. Additionally, the biogenesis of these two types of triterpenes is discussed and a refined pathway is proposed.

Abstract
The Alisma rhizoma is widely used in the therapy of diabetes in traditional folk medicine of China. Compositional analysis of the alcohol extract of Alismatis Rhizoma (AEA) revealed that the eight compounds gotten from AEA are all belonging to protostane-type triterpenes. The AEA and compounds were incubated with 3T3-L1 preadipocytes, glucose level in the 3T3-L1 adipocytes culture medium and lipid content in 3T3-L1 adipocytes were measured, and analysis of alpha-glucosidase inhibition of AEA and compounds. At the same time, the uptake of AEA by 3T3-L1 adipocytes and the metabolism of AEA in SD rats were analyzed by HPLC-ESI/MS. As result, AEA increased glucose uptake in 3T3-L1 adipocyte model, not increase adipogenesis; AEA inhibited alpha-glucosidase activity; alisol A-24-aceate (8) was absorbed by 3T3-L1 adipocytes; and two compounds were detected in blood and three were detected in urine in SD rats. So AEA had protostane-type triterpenes, these type compounds in AEA may have hypoglycemic activity via inhibition of alpha-glucosidase activity and promotion of glucose uptake. In contrast to the anti-diabetic drug thiazolidinediones, they did not induce adipogenesis, avoiding the displeased effects of rosiglitazone.

Abstract
Alisol derivatives are unique protostane-type triterpenoid compounds that are isolated from Alismatis rhizoma, which is a well-known traditional medicine in East Asia. In the present study, we investigated the effects of protostane-type triterpenoids (AA, Alisol A; AB, Alisol B; AB-ac, Alisol B 23-acetate; AC-ac, Alisol C 23-aceteate) on 5-HT-induced currents mediated by the human 5-HT(3)A receptor expressed in Xenopus laevis oocytes. Co-treatment with triterpenoids regulated the 5-HT-induced inward peak current in a concentration-dependent and reversible manner. In addition, regulation of I(5-HT) by triterpenoids occurred in a non-competitive manner. Taken together, these results indicate that triterpenoids may regulate the 5-HT(3)A receptors that are expressed in Xenopus oocytes. Furthermore, this regulation of the ligand-gated ion channel activity by triterpenoids may be one of the pharmacological actions of Alismatis rhizoma.

Abstract
Emerging evidence suggests that autophagic modulators have therapeutic potential. This study aims to identify novel autophagic inducers from traditional Chinese medicinal herbs as potential antitumor agents. Using an image-based screen and bioactivity-guided purification, we identified alisol B 23-acetate, alisol A 24-acetate, and alisol B from the rhizome of Alisma orientale as novel inducers of autophagy, with alisol B being the most potent natural product. Across several cancer cell lines, we showed that alisol B-treated cells displayed an increase of autophagic flux and formation of autophagosomes, leading to cell cycle arrest at the G(1) phase and cell death. Alisol B induced calcium mobilization from internal stores, leading to autophagy through the activation of the CaMKK-AMPK-mammalian target of rapamycin pathway. Moreover, the disruption of calcium homeostasis induces endoplasmic reticulum stress and unfolded protein responses in alisol B-treated cells, leading to apoptotic cell death. Finally, by computational virtual docking analysis and biochemical assays, we showed that the molecular target of alisol B is the sarcoplasmic/endoplasmic reticulum Ca(2+) ATPase. This study provides detailed insights into the cytotoxic mechanism of a novel antitumor compound.

Abstract
We examined the inhibitory effects of alismol, a sesquiterpenoid isolated from Alismatis Rhizoma, on vascular contractions induced by high concentrations of K+ and Ca2+, and on 45Ca2+ retention in normal and in high K+-containing medium. Alismol affected neither the resting tension nor the 45Ca2+ retention in normal medium, but it inhibited sustained contraction and increased 45Ca2+ retention induced by high K+ concentrations. Alismol did not affect norepinephrine-induced contractions in normal medium, nor phasic contractions in Ca2+-free medium. These results suggested that alismol inhibited mainly Ca2+ influx through a voltage-dependent Ca2+ channel.
