Nat Prod Res 2024:1-9. [PMID: 39319875 DOI: 10.1080/14786419.2024.2407510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2024] [Revised: 08/28/2024] [Accepted: 09/17/2024] [Indexed: 09/26/2024]
Abstract
To the best of our knowledge, this is the first chemical study of Guarea glomerulata that led to the isolation and characterisation of nine distinct compounds from its methanolic leaves extract including one new trinortriterpenoid glomerulatin along with eight known compounds amongst which five compounds namely azadirone, oleanolic acid, sericoside, cleomiscosin D and griffonin reported for the first time from the genus Guarea. All the isolated compounds have been evaluated in vitro for their antiplasmodial potency against the chloroquine-sensitive strain P. falciparum 3D7. The results showed that glomerulatin and azadirone were the most active compounds with IC50 values of 1.02 ± 0.2 μM and 1.48 ± 0.4 μM, respectively. This study enriches the chemistry of the genus Guarea and further supports the identification of Meliaceae plants as a good source of antiplasmodial candidates for the development of new potent drugs against malaria.

The isolation of novel pregnane steroids from Aglaia pachyphylla Miq. and the cytotoxicity against breast cancer cell lines (MCF-7). RSC Adv 2024; 14:25042-25047. [PMID: 39135974 PMCID: PMC11317792 DOI: 10.1039/d4ra04727c] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2024] [Accepted: 08/05/2024] [Indexed: 08/15/2024] Open
Abstract
Steroid groups isolated from many plants are known to play a significant role in various biological systems. Therefore, this research aimed to analyze two novel pregnane steroids, pachylenone A (1) and pachylenone B (2), isolated from Aglaia pachyphylla Miq. The cytotoxicity of the steroids was evaluated against MCF-7 breast cancer cell lines with other known steroid compounds, namely 5α-dihydroprogesterone (3), GSD-8 (4), trans-5α-pregn-l7(20)-en-3,16-dion (5), 20β-hydroxy-5αH-pregnan-3-one (6), 3β-hydroxy-5α-pregnan-20-one (7), aglaiasterol B (8), and 2β,3β-dihydroxypregnan-16-one (9). Meanwhile, structural elucidation was achieved through different spectroscopic methods including one and two-dimensional NMR, as well as mass spectroscopy and quantum chemical calculations (TD-DFT and NMR DP4+ probability). The cytotoxic effects of steroid compounds (1-9) on MCF-7 lines were also examined. The results showed that compound 8 had the strongest activity with an IC50 value of 228 μM, followed by compound 6 (IC50 568,76 μM), and pachylenone A (1) (IC50 768.73 μM). As a recommendation for future research, other activities of these compounds should be evaluated.

Bailly C. Limonoids isolated from Chisocheton ceramicus Miq. and the antiadipogenic mechanism of action of ceramicine B. Arch Pharm (Weinheim) 2024; 357:e2400160. [PMID: 38678480 DOI: 10.1002/ardp.202400160] [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: 03/01/2024] [Revised: 04/06/2024] [Accepted: 04/08/2024] [Indexed: 05/01/2024]
Abstract
Different types of limonoids have been isolated from plants of the Chisocheton genus, notably from the species Chisocheton ceramicus Miq. which is largely distributed in the Indonesian archipelago and Malaysia region. A variety of natural products have been found in the bark of the tree and characterized as antimicrobial and/or antiproliferative agents. The isolated limonoids include chisomicines A-E, proceranolide, and a few other compounds. A focus is made on a large series of limonoids designated ceramicines A to Z including derivatives with antiparasitic activities, antioxidant, antimelanogenic, and antiproliferative effects and/or acting as regulators of lipogenesis. The lead compound in the series is ceramicine B functioning as a potent inhibitor of lipid droplet accumulation (LDA). Extracts from Chisocheton ceramicus and ceramicines have shown anti-LDA effects, with little or no cytotoxic effects. Ceramicine B is the most active compound functioning as a regulator of lipid storage in cells and tissues. Ceramicine B is a transcriptional repressor of peroxisome proliferator-activated receptor γ (PPARγ) and an inhibitor of phosphorylation of the transcription factor FoxO1, acting via an upstream molecular target. Targeting of glycogen synthase kinase-3β is proposed, based on the analogy with structurally related limonoids known to target this enzyme, and supported by a molecular docking analysis. The target and pathway implicated in ceramicine B activity are discussed. The analysis shed light on ceramicine B as a natural product precursor for the design of novel compounds capable of reducing LDA in cells and of potential interest for the treatment of obesity, liver diseases, and other pathologies.

DC. extract inhibits NLRP3 inflammasome by suppressing its ATPase activity. JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117711. [PMID: 38176663 DOI: 10.1016/j.jep.2024.117711] [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: 11/21/2023] [Revised: 12/28/2023] [Accepted: 01/02/2024] [Indexed: 01/06/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Guarea genus comprises tropical and subtropical terrestrial herbs inhabiting Central and South America. These plants, including Guarea guidonia (L.) Sleumer, have anti-inflammatory, analgesic, antibacterial, antiviral, and immune-enhancing properties. AIM OF THE STUDY Although various species of the Guarea genus are known for their medicinal properties, comprehensive data on their anti-inflammatory effects remain limited. Therefore, we investigated the NLRP3 inflammasome-inhibiting effects of the Guarea genus in this study. MATERIALS AND METHODS To evaluate the anti-inflammatory activities of 18 members of the Guarea genus, we treated NLRP3 inflammasome activators with their extracts in LPS-primed J774A.1 and THP-1 cells. Cell viability was determined by water soluble tetrazolium salt (WST) and cytokine production, protein expression, and nuclear fractionation were determined by western blotting. Reactive oxygen species (ROS) production and apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) oligomerization were measured using confocal microscopic analysis. Inflammation-induced zebrafish was used in the in vivo experiments. RESULTS Among the 18 Guarea members tested, Guarea microcarpa C. DC. extract (GM) exhibited no cytotoxicity and specifically suppressed the activation of the NLRP3 inflammasome, but not of the AIM2 or NLRC4 inflammasomes, by inhibiting the ATPase activity of NLRP3. This was achieved without affecting NF-κB signaling, potassium efflux, or intracellular ROS production, all of which are involved in NLRP3 activation. The reduced ATPase activity of NLRP3 led to decreased ASC oligomerization. Furthermore, GM exhibited anti-inflammatory effects in vivo. Additionally, GM treatment alleviated inflammation at the organismal level in an LPS-induced inflammation model using zebrafish embryos. CONCLUSION Our results demonstrate the anti-inflammatory effects of GM via suppressing the NLRP3 inflammasome. Therefore, GM can be a potential therapeutic candidate for various inflammatory diseases caused by aberrant NLRP3 inflammasome activation.

[PMID: 37375428 DOI: 10.3390/molecules28124874] [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: 03/18/2023] [Revised: 06/09/2023] [Accepted: 06/10/2023] [Indexed: 06/29/2023] Open
Abstract
Sesquiterpenoids, an important class of natural products possessing three isoprene-derived units, are widely distributed across plants and have a variety of biological activities. All sesquiterpenoids are derived from farnesyl pyrophosphate (FPP), a biosynthesis precursor that can form various carbon skeletons. In order to provide a reference for further research and development of these compounds, this review focused on the increasing number of isolated and volatile sesquiterpenoids found to be produced by plants of the Meliaceae family between 1968 and 2023. The related articles were collected from SciFinder, Google Scholar, and PubMed. According to a literature review, several studies were started for more than 55 years on the plant's stem barks, twigs, leaves, flowers, seeds, and pericarps, where approximately 413 sesquiterpenoid compounds from several groups such as eudesmane, aromadendrane, cadinane, guaiane, bisabolane, furanoeremophilane, humulene, germacrane, and oppositane-type were isolated and identified with some minor products. Additionally, the hypothetical route of sesquiterpenoids biosynthesis from this family was identified, and eudesmane-type was reported to be 27% of the total compounds. The antimicrobial, antidiabetic, antioxidant, antiplasmodial, antiviral, and cytotoxic activities of the isolated compounds and major volatile sesquiterpenoids constituent on essential oil were also evaluated. The result showed the fundamental of using the sesquiterpenoid compounds from the Meliaceae family in traditional medicine and the discovery of new drugs.
