Convolamine, a tropane alkaloid extracted from Convolvulus plauricalis, is a potent sigma-1 receptor-positive modulator with cognitive and neuroprotective properties. Phytother Res 2024; 38:694-712. [PMID: 38011416 DOI: 10.1002/ptr.8068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Revised: 10/26/2023] [Accepted: 10/28/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND AND AIM By using an in vivo phenotypic screening assay in zebrafish, we identified Convolamine, a tropane alkaloid from Convulvus plauricalis, as a positive modulator of the sigma-1 receptor (S1R). The wfs1abKO zebrafish larva, a model of Wolfram syndrome, exhibits an increased visual-motor response due to a mutation in Wolframin, a protein involved in endoplasmic reticulum-mitochondria communication. We previously reported that ligand activating S1R, restored the cellular and behavioral deficits in patient fibroblasts and zebrafish and mouse models. EXPERIMENTAL PROCEDURES We screened a library of 108 repurposing and natural compounds on zebrafish motor response. KEY RESULTS One hit, the tropane alkaloid Convolamine, restored normal mobility in wfs1abKO larvae without affecting wfs1abWT controls. They did not bind to the S1R agonist/antagonist binding site nor dissociated S1R from BiP, an S1R activity assay in vitro, but behaved as a positive modulator by shifting the IC50 value of the reference agonist PRE-084 to lower values. Convolamine restored learning in Wfs1∆Exon8 , Dizocilpine-treated, and Aβ25-35 -treated mice. These effects were observed at low ~1 mg/kg doses, not shared by Convolvine, the desmethyl metabolite, and blocked by an S1R antagonist. CONCLUSION AND IMPLICATIONS Convolamine therefore acts as an S1R positive modulator and this pharmacological action is relevant to the traditional use of Shankhpushpi in memory and cognitive protection.

Abstract
A methanol extract of the flowers of Mammea siamensis (Miq.) T. Anders. (Calophyllaceae) showed anti-proliferative activity against human prostate carcinoma LNCaP cells (IC50 = 2.0 µg/mL). Two new coumarin-related polysubstituted benzofurans, mammeasins P (1) and Q (2), and a known polysubstituted coumarin mammea B/AC cyclo F (39) were isolated from the extract along with 44 previously reported polysubstituted coumarin constituents (3–38 and 40–47). The structures of two new compounds (1 and 2) were determined based on their spectroscopic properties derived from the physicochemical evidence including NMR and MS analyses and taking the plausible generative pathway into account. Among the coumarin constituents, mammeasins A (3, IC50 = 1.2 µM) and B (4, 0.63 µM), sugangin B (18, 1.5 µM), kayeassamins E (24, 3.0 µM) and G (26, 3.5 µM), and mammeas E/BA (40, 0.88 µM), E/BB (41, 0.52 µM), and E/BC (42, 0.12 µM) showed relatively potent anti-proliferative activity.

Life-threatening pediatric poisoning due to ingestion of Bufo bufo toad eggs: A case report. Toxicon 2022; 217:13-16. [PMID: 35839868 DOI: 10.1016/j.toxicon.2022.07.005] [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: 04/30/2022] [Revised: 07/07/2022] [Accepted: 07/08/2022] [Indexed: 11/27/2022]
Abstract
Bufo parotid glands and eggs contain cardiac glycosides also known as bufadienolides. This class of molecules can cause digoxin-like cardiac toxicity, as they can block the sodium potassium-adenosine triphosphatase (Na/K-ATPase) pump. Poisoning with these toxins is rare but carries a high mortality risk. There are only a few cases of toad poisoning that have been reported worldwide, mainly in the southern hemisphere. We will describe the case of a child on the autistic spectrum disorder who developed an acute and severe cardiac bradyarrhythmia soon after being in a mountain creek. The child ingested a large quantity of Bufo bufo toad eggs and developed bradycardia (35/min) associated with junctional rhythm with narrow QRS complexes. The poison control center (PCC) indicated the use of atropine on the way to the nearest hospital and the administration of antidotal therapy, i.e., anti-digoxine fragment antibodies (DigiFab), as soon as possible. The patient was transferred by air ambulance to the Regional Referral Pediatric Hospital (RRPH), tested for digoxin blood level by immuno-essay (0.68 ng/mL) and successfully treated with five vials of DigiFab, since atropine administration produced only a fleeting effect on the cardiac rhythm. Patient was discharged 48 hours after poisoning. The presence of bufadienolides in the toad eggs was also confirmed. To our knowledge, this is the first report of toad egg poisoning in Europe. The administration of Digifab helped to reverse the bufadienolide cardiac toxicity.

Abstract
Michelia × alba (M. alba) is a flowering tree best known for its essential oil, which has long been used as a fragrance ingredient for perfume and cosmetics. In addition, the plant has been used in traditional medicine in Asia and dates back hundreds of years. To date, there is a limited number of publications on the bioactivities of M. alba, which focused on its tyrosinase inhibition, antimicrobial, antidiabetic, anti-inflammatory, and antioxidant activities. Nevertheless, M. alba may have additional unexplored bioactivities associated with its bioactive compounds such as linalool (72.8% in flower oil and 80.1% in leaf oil), α-terpineol (6.04% flower oil), phenylethyl alcohol (2.58% flower oil), β-pinene (2.39% flower oil), and geraniol (1.23% flower oil). Notably, these compounds have previously been reported to exhibit therapeutic activities such as anti-cancer, anti-inflammation, anti-depression, anti-ulcer, anti-hypertriglyceridemia, and anti-hypertensive activities. In this review paper, we examine and discuss the scientific evidence on the phytochemistry, bioactivities, and traditional uses of M. alba. Here, we report a total of 168 M. alba biological compounds and highlight the therapeutic potential of its key bioactive compounds. This review may provide insights into the therapeutic potential of M. alba and its biologically active components for the prevention and treatment of diseases and management of human health and wellness.

Ethnopharmacological nexus between the traditional Thai medicine theory and biologically based cancer treatment. JOURNAL OF ETHNOPHARMACOLOGY 2022; 287:114932. [PMID: 34953977 DOI: 10.1016/j.jep.2021.114932] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 12/14/2021] [Accepted: 12/19/2021] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The two major theories utilized for diagnosis and treatment in Traditional Thai Medicine (TTM) are the Four Element Theory and the Herbal Flavor Theory. A TTM "Poh-Pu" Remedy has been effectively utilized in Thailand for cancer therapy for centuries. AIMS OF STUDY To investigate anti-inflammatory activity and liver cancer cytotoxicity of Poh-Pu remedy. To determine relationships between the TTM Herbal Flavor theory and the Four Element theory and total flavonoid content and biological activities of Poh-Pu Remedy plant extracts. MATERIALS AND METHODS Each plant ingredient was macerated with 95% ethanol. The extracts were investigated for cytotoxic activity against liver cancer using a sulforhodamine B assay, and anti-inflammatory activity was evaluated by inhibition of nitric oxide production. The total flavonoid content was determined by an aluminum chloride colorimetric assay. The relationships between the TTM theories, total flavonoid content, and biological activities were evaluated by correlation and cluster analysis. RESULTS Mammea siamensis exerted potent cytotoxicity against hepatocellular carcinoma (HepG2) cell lines with an IC50 of 3.15 ± 0.16 μg/mL and low cytotoxicity to the non-cancerous cells (HaCat) with an IC50 33.39 ± 0.40 μg/mL (Selective index (SI) = 10.6). Tiliacora triandra was selectively cytotoxic to cholangiocarcinama (KKU-M156) cells with an IC50 of 12.65 ± 0.92 μg/mL (SI = 6.4). Curcuma comosa was the most potent anti-inflammatory inhibitor of nitric oxide production with an IC50 of 2.75 ± 0.34 μg/mL. Campomanesia aromatica exhibited the highest total flavonoid content of 259.7 ± 3.21 mg quercetin equivalent/g. Pungent plants were most prevalent in the TTM remedy. CONCLUSION Pungent, fragrant, bitter and nauseating plants utilized in TTM cancer remedy were successfully investigated and identified several lead plants and components with cytotoxic and antiinflammatory activity that require further study. The TTM wind element theory appeared to be aligned with cancer-related activity. Biological activity results of taste from herbs related with The TTM Herbal Flavor theory. The extra-oral locations of flavor receptors are a promising target for biological activity of TTM which require further scrutiny and identified several lead plants and components with cytotoxic and antiinflammatory activities that also require further study.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Acanthus mollis L. (Bear's Breeches) is a wide-spread medicinal and ornamental plant and is particularly suited to exemplarily illustrate the diverse aspects of invasion biology by neophytes. Since ancient times, it has been a popular Mediterranean ornamental plant in horticulture and served as model for the decoration of column capitals in architecture. AIM OF THE STUDY In the present review, we aimed to give an overview about ethnopharmacology, phytochemistry, chemical ecology, and invasion biology of A. mollis. Thus, the importance of plantation cultivation in the presence of ecologically problematic species and environmental protection were emphasized. MATERIALS AND METHODS We conducted an extensive literature search via screening PubMed, Scopus, and Web of Science, in order to compile the data about A. mollis and its role on invasion biology and thereby attracting attention to the prominence of the horticultural and agricultural cultivation of plant species with a special focus on A. mollis as a model. RESULTS AND CONCLUSION Phytochemical analyses revealed secondary metabolites from the classes of flavonoids, phenols, phenylpropanoids, anthraquinones arylnaphthalene lignans, phytosterols and others. Extracts of A. mollis and isolated phytochemicals not only exert assorted activities including antioxidant, anti-inflammatory and neuroprotective in murine and human experimental models, but also act against plant parasites (bacteria, insects, mollusks, fungi), protecting the plant from microbial attack and herbivorous predators. A. mollis has been used in traditional medicine to treat dermatological ailments, gastrointestinal diseases, ulcers and even tumors. Nevertheless, the robustness and rapid growth of A. mollis as well as the global horticultural trade facilitated its invasion into fragile ecosystems of Australia, New Zealand, and several other spots around the globe in Northern Europe (Great Britain), Asia (China, India), South Africa, and South America (Argentina). The release of A. mollis from gardens into the wild represents a considerable danger as invasive species are threatening biodiversity and leading to the extinction of domestic plants in the long run. Likewise, the likelihood of other medicinal plants in terms of invasion biology are needed to be fully recognized and discussed.

Abstract
More than half of Thai patients with cancer take herbal preparations while receiving anticancer therapy. There is no systematic or scoping review on interactions between anticancer drugs and Thai herbs, although several research articles have that Thai herbs inhibit cytochrome P450 (CYP) or efflux transporter. Therefore, we gathered and integrated information related to the interactions between anticancer drugs and Thai herbs. Fifty-two anticancer drugs from the 2020 Thailand National List of Essential Medicines and 75 herbs from the 2020 Thai Herbal Pharmacopoeia were selected to determine potential anticancer drug–herb interactions. The pharmacological profiles of the selected anticancer drugs were reviewed and matched with the herbal pharmacological activities to determine possible interactions. A large number of potential anticancer drug–herb interactions were found; the majority involved CYP inhibition. Efflux transporter inhibition and enzyme induction were also found, which could interfere with the pharmacokinetic profiles of anticancer drugs. However, there is limited knowledge on the pharmacodynamic interactions between anticancer drugs and Thai herbs. Therefore, further research is warranted. Information regarding interactions between anticancer drugs and Thai herbs should provide as a useful resource to healthcare professionals in daily practice. It could enable the prediction of possible anticancer drug–herb interactions and could be used to optimize cancer therapy outcomes.

Abstract
Geranylated coumarins named mammeasins G-J (1-4) were isolated from the methanol extract of the flowers of Mammea siamensis (Miq.) T. Anders. (Calophyllaceae) originating in Thailand. Their structures were established based on detailed spectroscopic analyses. The isolates, including previously reported coumarin constituents (5-28), exhibited anti-proliferative activities against human carcinoma cell lines HSC-2, HSC-4, MKN-45, and MCF-7. Mammeasin A (7, IC50 = 13.6 μM) and surangin B (15, 15.2 μM), both consisting of the geranyl group, were found to show relatively strong activities against HSC-4 cells and their mechanisms of action were found to involve apoptotic cell death.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2018; 50:213-222. [PMID: 30466981 DOI: 10.1016/j.phymed.2018.09.169] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2017] [Revised: 08/10/2018] [Accepted: 09/17/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Cancer is one of the most common life-threatening diseases worldwide; many patients develop multidrug resistance after treatment with anticancer drugs. The main mechanism leading to multidrug resistance is the overexpression of ABC transporters in cancer cells. Chemosensitizers are needed to inhibit the activity of ABC transporters, resulting in higer intracellular concentration of anticancer drugs. Some secondary metabolites have been reported to be chemosensitizers by inhibiting ABC transporters. Epigallocatechin gallate (EGCG), tannic acid, and curcumin were employed in this study. Different assays were used to detect whether they have the ability to inhibit P-gp activity and overcome multidrug resistance in cancer cells overexpressing P-gp. Hypothesis/Purpose: CEM/ADR 5000 and Caco-2 cell lines, which overexpress P-gp, are multidrug resistant cell lines. We first detected whether the combination of polyphenols (EGCG, tannic acid, curcumin) and doxorubicin, an anticancer drug, is synergistic or not. To further understand the potential mechanism, EGCG, tannic acid, and curcumin were tested to check whether they have the ability to inhibit P-gp activity. When P-gp activity is inhibited, the intracellular concentration of doxorubicin is higher, resulting in enhanced cytotoxicity of doxorubicin. STUDY DESIGN The P-gp overexpressing human colon cancer cell line Caco-2 and human T-lymphoblastic leukemia cell line CEM/ADR 5000 were used in this study. Two-drug combinations (doxorubicin + polyphenol) and three-drug combinations (doxorubicin + polyphenol + digitonin) were tested to examine potential synergism. The potential mechanism leading to synergism would be the inhibition of P-gp activity. A Rhodamine 123 assay and Calcein-AM assay in Caco-2 and CEM/ADR 5000, respectively, were used to detect P-gp inhibition by EGCG, curcumin, and tannic acid. METHODS MTT assay was used to determine the cytotoxicity of doxorubicin, polyphenols and digitonin alone, and then their combinations. Furthermore, Rhodamine 123 and Calcein-AM were used to detect the effects of polyphenols on the activity of P-gp. RESULTS The results demonstrated that a combination of non-toxic concentrations of each polyphenol with doxorubicin synergistically sensitized Caco-2 and CEM/ADR 5000 cells. Furthermore, three-drug combinations (doxorubicin + polyphenol + digitonin) were much more effective. In addition, the activity of P-gp in Caco-2 and CEM/ADR 5000 cells was measured. Consistent with the combination results, tannic acid and curcumin decreased the activity of P-gp both in Caco-2 and CEM/ADR 5000. EGCG, which weakly affected the activity of P-gp in CEM/ADR 5000, only had an effect on P-gp under higher concentration in Caco-2 cells. CONCLUSION Our results show that EGCG, curcumin, and tannic acid, when combined with doxorubicin, can exert synergism, mediated by a reduced activity of P-gp. This study suggests that polyphenols, by modulating the activity of P-gp, may be used as chemosensitisers.

Abstract
Allicin is the most biologically active substance present in garlic. It can be synthesized or obtained by extraction of fresh garlic. Transformation products of allicin are also biologically active. The aim of this study was to examine the antioxidant activity of synthesized allicin and its transformation products obtained using microwaves in methanol at 55 °C as well as their effect on HeLa cells growth. The antioxidant activity was determined by DPPH (2,2-diphenyl-1-picrylhydrazyl radical) test. The effect on HeLa cells growth was determined by MTT (3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) test. For MTT test, allicin and its transformation products were dispersed in carmellose sodium solution and examined in concentrations ranging from 0.3 μg/mL to 3 mg/mL. Allicin showed stronger antioxidant activity than the transformation products. A maximum degree of neutralization of DPPH radicals, about 90%, was reached when the concentration of allicin was 2 mg/mL, with an EC50 (concentration of sample which is required for reduction of the initial concentration DPPH radicals to 50%) value of 0.37 mg/mL. In our study, allicin and its transformation products were not cytotoxic to HeLa cells under the examined conditions. The highest concentration of allicin and its transformation products had a slight antiproliferative effect, with a more pronounced effect of allicin, which reflected on the morphology of HeLa cells. The examined substances are safe to use on epithelial cells at concentrations up to 3 mg/mL when applied in carmellose sodium solution. Using carmellose sodium as a dispersing agent could be recommended as a good approach for testing liposoluble substances in liquid cell cultures.
