Challenging Structure Elucidation of Lumnitzeralactone, an Ellagic Acid Derivative from the Mangrove Lumnitzera racemosa. Mar Drugs 2023; 21:md21040242. [PMID: 37103381 PMCID: PMC10144801 DOI: 10.3390/md21040242] [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: 03/16/2023] [Revised: 04/11/2023] [Accepted: 04/12/2023] [Indexed: 04/28/2023] Open
Abstract
The previously undescribed natural product lumnitzeralactone (1), which represents a derivative of ellagic acid, was isolated from the anti-bacterial extract of the Indonesian mangrove species Lumnitzera racemosa Willd. The structure of lumnitzeralactone (1), a proton-deficient and highly challenging condensed aromatic ring system, was unambiguously elucidated by extensive spectroscopic analyses involving high-resolution mass spectrometry (HRMS), 1D 1H and 13C nuclear magnetic resonance spectroscopy (NMR), and 2D NMR (including 1,1-ADEQUATE and 1,n-ADEQUATE). Determination of the structure was supported by computer-assisted structure elucidation (CASE system applying ACD-SE), density functional theory (DFT) calculations, and a two-step chemical synthesis. Possible biosynthetic pathways involving mangrove-associated fungi have been suggested.

Abstract
Lumnitzera littorea and Lumnitzera racemosa are mangrove species distributed widely along the Indonesian coasts. Besides their ecological importance, both are of interest owing to their wealth of natural products, some of which constitute potential sources for medicinal applications. We aimed to discover and characterize new anti-infective compounds, based on population-level sampling of both species from across the Indonesian Archipelago. Root metabolites were investigated by TLC, hyphenated LC-MS/MS and isolation, the internal transcribed spacer (ITS) region of rDNA was used for genetic characterization. Phytochemical characterization of both species revealed an unusual diversity in sulfated constituents with 3,3’,4’-tri-O-methyl-ellagic acid 4-sulfate representing the major compound in most samples. None of these compounds was previously reported for mangroves. Chemophenetic comparison of L. racemosa populations from different localities provided evolutionary information, as supported by molecular phylogenetic evidence. Samples of both species from particular locations exhibited anti-bacterial potential (Southern Nias Island and East Java against Gram-negative bacteria, Halmahera and Ternate Island against Gram-positive bacteria). In conclusion, Lumnitzera roots from natural mangrove stands represent a promising source for sulfated ellagic acid derivatives and further sulfur containing plant metabolites with potential human health benefits.

Abstract
Petroselinum crispum var. neapolitanum Danert (Apiaceae) (PC), popularly known as parsley, is an herb native to the Mediterranean region widely cultivated around the world for culinary and ethnomedicinal purposes. The herb is traditionally used in various parts of the world to treat arterial hypertension, hemorrhoid, nose bleeding, hyperlipidemia, and pain, among other indications. The aim of this study was to evaluate the antithrombotic activity of an aqueous extract PC in rats. Aerial parts of a flat-leaf variety of parsley were extracted by decoction. In vivo thrombosis in rat models as well as ex vivo assays were used in the evaluation of PC antithrombotic effects. Intravenous administration of PC (25 mg/kg.b.w), 5 min before thrombosis induction, reduced the venous thrombus formation by 98.2%, while oral administration (125 mg/kg.b.w) impaired it by 76.2%. In the arterial thrombosis model, the oral administration of PC at 15 or 25 mg/kg.b.w, 60 min before thrombosis induction, increased the carotid artery occlusion time by 150% (37.0 ± 6.44 min) and 240% (more than 60 min), respectively. A HPLC-DAD-MS/MS profile of PC extract used in this study was provided. Apiin showed to be the most abundant phenolic compound in the extract. It also revealed the presence of many coumaric acid derivatives. Our results indicate that PC is a potential candidate for the development of a phytotherapeutic drug in the treatment of thromboembolic diseases and provide a detailed chemical profile useful for controlling PC extract production in view of phytotherapy.

Phytother Res 2019; 33:989-997. [PMID: 30693991 DOI: 10.1002/ptr.6292] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Revised: 11/17/2018] [Accepted: 12/19/2018] [Indexed: 12/20/2022]
Abstract
Ginkgo biloba L., well known as living fossil, have various pharmacological activities. Eighteen compounds were isolated from Ginkgo male flowers including a novel matsutake alcohol glycoside, Ginkgoside A (1), and 17 known compounds-calaliukiuenoside (2), benzylalcohol O-α-l-arabinopyranosyl-(1 → 6)-β-d-glucopyranoside (3), amentoflavone (4), sciadopitysin (5), bilobetin (6), isoginkgetin (7), olivil 4-O-β-d-glucopyranoside (8), dihydrodehydrodiconiferyl alcohol-4-O-β-d-glucoside (9), (+)-cyclo-olivil-6-O-β-d-glucopyranoside (10), (-)-isolariciresinol 4-O-β-d-glucopyranoside (11), coniferin (12), trans-cinnamic acid-4-O-β-d-glucopyranoside (13), p-coumaryl alchol glucoside (14), stroside B (15), methylconiferin (16), cis-p-coumaric acid 4-O-β-d-glucopyranoside (17), and cis-coniferin (18). Thirteen of these compounds had not previously found in Ginkgo. All extractive fractions and isolated compounds were evaluated for their anti-inflammatory ability in the lipopolysaccharide-induced RAW264.7 macrophages. The ethanol extract of Ginkgo flowers and the chloroform and ethyl acetate fractions can significantly decrease nitric oxide (NO), interleukin-6 (IL-6), and prostaglandin E2 (PGE2 ) production at 100 μg/ml. The most effective compounds, bilobetin (6) and isoginkgetin (7), elevated the NO inhibition ratios to 80.19% and 82.37% at 50 μM, respectively. They also exhibited significant dose-dependent inhibitory effects on tumor necrosis factor-α, IL-6, PGE2 , inducible NO synthase mRNA, and cyclooxygenase-2 mRNA levels. So they can be promising candidates for the development of new anti-inflammatory agents.

Abstract
Cancer is one of the biggest problems in public health worldwide. Plants have been shown important role in anticancer research. Viscum album L. (Santalaceae), commonly known as mistletoe, is a semi-parasitic plant that grows on different host trees. In complementary medicine, extracts from European mistletoe (Viscum album L.) have been used in the treatment of cancer. The study was conducted to identify chemical composition and antitumor potential of Viscum album tinctures. Chemical analysis performed by high resolution chromatography equipped with high resolution mass spectrometer identified caffeic acid, chlorogenic acid, sakuranetin, isosakuranetin, syringenin 4-O-glucoside, syringenin 4-O-apiosyl-glucoside, alangilignoside C and ligalbumoside A compounds. Some of these compounds are probably responsible for the reduction of tumoral cellular growth in a dose-dependent manner. It was observed that melanoma murine cells (B16F10) were more sensitive to V. album tinctures than human leukaemic cells (K562), besides non-tumoral cells (MA-104) had a much lower cytotoxicity to them. Apoptotic-like cells were observed under light microscopy and were confirmed by a typical DNA fragmentation pattern. Additionally, flow cytometry results using Annexin-V/FITC permitted to quantify increased expression of early and late apoptotic markers on tumoral cells, confirming augmented Sub G0 population, which was probably associated with a consistent decrease in G1, and an increase in S or G2/M populations. Results indicate the chemical composition of V. album tinctures influences the mechanisms of in vitro tumoral cell death, suggesting a potential use in cancer pharmacotherapy research.
