Leucosceptosides A and B: Two Phenyl-Ethanoid Glycosides with Important Occurrence and Biological Activities. Biomolecules 2022; 12:1807. [PMID: 36551235 PMCID: PMC9775335 DOI: 10.3390/biom12121807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/24/2022] [Accepted: 11/28/2022] [Indexed: 12/12/2022] Open
Abstract
In this review paper, the occurrence in the plant kingdom, the chemophenetic value and the biological activities associated with two specific phenyl-ethanoid glycosides, i.e., leucosceptoside A and leucosceptoside B, were reported. This is the first work ever conducted on such a subject. Analysis of the literature data clearly led to three important conclusions: leucosceptoside A is much more common in plants than leucosceptoside B; leucosceptoside A exerts more biological activities than leucosceptoside B even if nothing can be generally concluded about which one is actually the most potent; neither of these compounds can be used as a chemophenetic marker. These three aspects and more are discussed in more depth in this work.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27123849. [PMID: 35744969 PMCID: PMC9231311 DOI: 10.3390/molecules27123849] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 06/07/2022] [Accepted: 06/11/2022] [Indexed: 11/16/2022]
Abstract
Australian tropical plants have been a rich source of food (bush food) and medicine to the first Australians (Aboriginal people), who are believed to have lived for more than 50,000 years. Plants such as spreading sneezeweed (Centipeda minima), goat’s foot (Ipomoea pes-caprae), and hop bush (Dodonaea viscosa and D. polyandra) are a few popular Aboriginal medicinal plants. Thus far, more than 900 medicinal plants have been recorded in the tropical region alone, and many of them are associated with diverse ethnomedicinal uses that belong to the traditional owners of Aboriginal people. In our effort to find anti-inflammatory lead compounds in collaboration with Aboriginal communities from their medicinal plants, we reviewed 78 medicinal plants used against various inflammation and inflammatory-related conditions by Aboriginal people. Out of those 78 species, we have included only 45 species whose crude extracts or isolated pure compounds showed anti-inflammatory properties. Upon investigating compounds isolated from 40 species (for five species, only crude extracts were studied), 83 compounds were associated with various anti-inflammatory properties. Alphitolic acid, Betulinic acid, Malabaric acid, and Hispidulin reduced proinflammatory cytokines and cyclooxygenase enzymes (COX-1 and 2) with IC50 values ranging from 11.5 to 46.9 uM. Other promising anti-inflammatory compounds are Brevilin A (from Centipeda minima), Eupalestin, and 5′-methoxy nobiletin (from Ageratum conyzoides), Calophyllolide (from Calophyllum inophyllum), and Brusatol (from Brucea javanica). D. polyandra is one example of an Aboriginal medicinal plant from which a novel anti-inflammatory benzoyl ester clerodane diterpenoid compound was obtained (compound name not disclosed), and it is in the development of topical medicines for inflammatory skin diseases. Medicinal plants in the tropics and those associated with indigenous knowledge of Aboriginal people could be a potential alternative source of novel anti-inflammatory therapeutics.

Abstract
Verbascoside is isolated from the whole plants of the Verbenaceae family and demonstrates significant levels of bioactivity. In this work, we report on the isolation of verbascoside, a phenolic glycoside, from the stems of Clerodendrum inerme collected in Vietnam and verify its structure by comparing its spectroscopic data with those reported in the literature. Verbascoside is then applied as a monomer for the electrochemical deposition of a layer of polyverbascoside onto glassy carbon electrodes toward Cu2+ sensing. Electrochemical results demonstrate that the polyverbascoside-modified glassy carbon electrode is highly selective for Cu2+ ions compared to other evaluated ions including Ni2+ and Co2+. The developed sensor can detect Cu2+ in a concentration range from 0 to 175 μM with a sensitivity of 0.372 µA µM−1 and a limit of detection of 50 nM Cu2+ ions.

Anti-inflammatory properties of the ethanol extract from Clerodendrum cyrtophyllum Turcz based on in vitro and in vivo studies. JOURNAL OF ETHNOPHARMACOLOGY 2020; 254:112739. [PMID: 32142867 DOI: 10.1016/j.jep.2020.112739] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 02/03/2020] [Accepted: 03/02/2020] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Clerodendrum cyrtophyllum Turcz, a plant belonging to the Verbenaceae family, has been used in traditional medicine for the treatment of various inflammatory diseases in many Asian countries. AIM OF THE STUDY The study aimed to evaluate anti-inflammatory properties of the ethanol extract from Clerodendrum cyrthophyllum Turcz leaves (EE-CC) through in vitro and in vivo models. MATERIAL AND METHODS Total phenolic and flavonoid contents in the extract were determined using colorimetric methods and HPTLC. In red blood cell membrane stabilization model, rat erythrocyte suspension was treated with crude ethanol extract at different concentrations, the hemoglobin content of the supernatant solution released by red blood hemolysis was estimated. We also evaluated the effects of the ethanol extract from this plant on the production of nitric oxide (NO), tumor necrosis factor alpha (TNF-α) in stimulated RAW 264.7 cells. In order to elucidate its anti-inflammatory molecular mechanisms, we further evaluated the effects of the EE-CC on the expression of the inflammatory genes in inflammation-induced zebrafish model by tail-cutting using qPCR analysis. RESULTS Colorimetric methods and HPTLC revealed high phenolic and flavonoid contents in the extract. In the red blood cell membrane stabilization model, the amount of hemoglobin released by red blood hemolysis significantly decreased in the presence of EE-CC, demonstrating a strong membrane stabilizing activity. EE-CC did not cause any toxic effect on cell viability but strongly inhibited NO and TNF-ɑ release due to LPS induction. The association with EE-CC significantly reduced the expression of cox-2, pla2, c3a, il-1(il1fma), il-8 (cxcl8b.1), tnf-α, and nf-ƙb, while increased the expression of the anti-inflammatory cytokine il-10 gene in cut-tail induced inflammation of zebrafish model. CONCLUSIONS Taken together, the results suggest that the raw ethanol extract from C. cyrtophyllum Turcz leaves presents potent anti-inflammatory activities and may be useful for the treatment of various inflammatory diseases.

Abstract
Clerodendrum is a genus of ca. 500 species in the family Lamiaceae and widely distributed throughout the whole world. Up to now, many species of this genus have been described in various indigenous systems of medicine and are used in preparation of folklore medicines for the treatment of various life-threatening diseases, and more than eleven species of the Clerodendrum genus have been very well studied for their chemical constituents and biological activities, and 283 compounds, including monoterpene and its derivatives, sesquiterpene, diterpenoids, triterpenoids, flavonoid and flavonoid glycosides, phenylethanoid glycosides, steroids and steroid glycosides, cyclohexylethanoids, anthraquinones, cyanogenic glycosides, and others have been isolated and identified. Pharmacological studies have shown that these compounds and extracts from the Clerodendrum genus have extensive activities, such as anti-inflammatory and anti-nociceptive, anti-oxidant, anti-hypertensive, anticancer, antimicrobial, anti-diarrheal, hepatoprotective, hypoglycemic and hypolipidemic, memory enhancing and neuroprotective, and other activities. In this review, we attempt to highlight over phytochemical progress and list the phytoconstituents isolated from the genus Clerodendrum reported so far. The biological activities of this genus are also covered.

Abstract
Cancer is a group of diseases which is categorized to differentiate into diverse cell types and move around in the body to sites of organogenesis that is key to the process of tumor genesis. All types of cancer fall into the group of malignant neoplastic diseases. In Bangladesh, cancer is now one of the foremost killer diseases and its personal, social, and economic bearing are huge. Plant-derived natural compounds (vincristine, vinblastine, etoposide, paclitaxel, camptothecin, topotecan, and irinotecan) are useful for the treatment of cancer. Since there is no extensive ethnobotanical research study in Bangladesh regarding the traditional uses of medicinal plants against neoplasms, therefore, a randomized ethnopharmacological surveys were carried out in 3 districts of Bangladesh to learn more about the usage of anticancer medicinal plants and their chemical constituents having antineoplastic activity. Comprehensive interviews were conducted to the folk medicine practitioners and medicinal plants as pointed out by them were photographed, collected, deposited, and identified at the Bangladesh National Herbarium. The various plant parts have been used by the healers which included whole plant, leaves, fruits, barks, roots, and seeds. This study evaluated considerable potential for discovery of novel compounds with less side effects in the management and prevention of malignancy in cancer.

Abstract
Tics are characterized by involuntary, sudden, rapid, repetitive, nonrhythmic, stereotyped movements or phonic productions. Those who suffer from either motor or phonic tics, but not both, for more than 1 year are diagnosed with chronic tic disorder. Several pharmacological interventions have been proposed for the treatment of tic disorder. Dopamine D2 receptor blockers and dopamine depletors are thought to be the most effective ones clinically. However, such treatments are suboptimal in terms of effectiveness and side effects, such as body weight gain and extrapyramidal symptoms. We report on a 13-year-old girl, with chronic motor tic disorder refractory to multiple anti-tic therapies, who showed dramatic improvement and remission after taking the crude leaf extract of Clerodendrum inerme (L) Gaertn. No side effects were observed during a follow-up of more than 2 years. To the best of our knowledge, this is the first report on the anti-tic effect of Clerodendrum inerme.

Abstract
A new megastigmane diglucoside, (3S,5R,6S,7E,9S)-megastigman-7-ene-5,6-epoxy-3,9-diol 3,9-O-beta-D-diglucopyranoside (3), was isolated from the aerial portion of Equisetum debile along with macarangioside D (debiloside A), sammangaoside A, (6R,9S)-3-oxo-alpha-ionol 9-O-beta-D-glucopyranoside, debiloside B, kaempferol 3-O-sophoroside, kaempferol 3,7-O-beta-D-diglucopyranoside, kaempferol 3-O-sophoroside-7-O-beta-D-glucopyranoside, phenylethyl O-beta-D-glucopyranoside, (Z)-3-hexenyl O-beta-D-glucopyranoside, (7S,8R)-dehydrodiconiferyl 4-O-beta-D-glucopyranoside, and L-tryptophan. The absolute configuration at C-6 of the original structure of debilo-side A was revised to 6R-configuration, and was identical with macarangioside D (1). From the aerial portion of E. diffusum, four compounds, sammangaoside A, kaempferol 3-O-sophoroside and L-tryptophan and (3S,5R,6S,7E,9S)-megastigman-7-ene-5,6-epoxy-3,9-diol 3-O-beta-D-glucopyranoside were identified. The spectroscopic data of (3S,5R,6S,7E,9S)-megastigman-7-ene-5,6-epoxy-3,9-diol 3-O-beta-D-glucopyranoside (13) were found to be identical with corchoionoside A (9R-isomeric compound). The structure of corchoionoside A was also discussed. Structure determinations were based on physical data and spectroscopic evidence.
