Nat Prod Res 2023; 37:3787-3797. [PMID: 36480815 DOI: 10.1080/14786419.2022.2153360] [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: 04/21/2022] [Revised: 11/21/2022] [Accepted: 11/26/2022] [Indexed: 12/13/2022]
Abstract
Tricholoma anatolicum is an edible mushroom from the matsutake group growing under Cedar trees. Bioactivity-guided fractionation of Tricholoma anatolicum afforded two new (1 and 2), three known ergosterols (3-6), and four known (6-9) compounds. Structures were identified as anatoluin A (1), anatoluin B (2), 5α,6α-epoxy-ergosta-7,22-dien,3β-ol (3), ergosterol-endoperoxide (4), ergosterol,3β-ol (5), 3,5-dihydroxyfuran-2(5H)-one (6), mannitol (7), turanose (8), fumaric acid (9) using spectroscopic techniques. The cytotoxic activity of extract and isolated compounds was performed using MTT assay against MCF7, HT29, H1299, and HeLa cancerous cell lines while toxicity against PDF and L929 fibroblast healthy cell lines. The lipid peroxidation inhibitory and ABTS•+ scavenging activities were used to determine antioxidant activity. The polar extracts exhibited significant cytotoxic activity. The more perfect is that the extracts and isolated compounds (1-5) were inactive against PDF and L929 healthy cell lines. Compounds 1-3 and 4 exhibited noticeable cytotoxic activity, while 1-5 moderately inhibited lipid peroxidation.

Abstract
Hepatocellular Carcinoma is one of the most frequently diagnosed cancer and highly refractory for chemotherapeutics agents. Therefore, the study aims to explore the new therapeutic agents for HCC. Phenolics rich fraction of leaves of P. lanceifolium was studied against hepatic cancer cell lines (HepG2) and NDEA-induced HCC rat model system. The obtained results showed that PLE induces reactive oxygen species (ROS) generation and chromatin condensation in nucleus and, alters the mitochondrial membrane potential (MMP) in HepG2 cell lines. The acridine orange/propidium iodide analysis and annexin-V FITC/PI analysis confirms that PLE induces apoptosis-mediated cell death in HepG2-cell lines. In In Vivo analysis, the administration of PLE in NDEA-induced rats declined the elevated biochemicals markers (ALT, AST, ALP, and GGT), interleukins, TNF-α, α-fetoprotein, carcinoembryonic antigen, and total bilirubin. PLE reinstated the level of antioxidant enzyme (GSH, GST, catalase, SOD, and GPX) and the expression of pro-apoptotic (p53, caspase-3, caspase-9, and Bax) and anti-apoptotic (Bcl-2) genes in a dose-dependent manner. The GC-MS analysis of Pterospermum lanceifolium fraction (PLE) represents the presence of palmitic acid, myristic acid, β-sitosterol, and catechin as major bioactive phytocompounds. The study discloses the new lead for HCC that can be further useful for development of new chemopreventive agent.

Abstract
Three new cyclic heptapeptides (1-3) together with three known compounds (4-6) were isolated from a solid rice culture of the soil-derived fungus Clonostachys rosea. Fermentation of the fungus on white beans instead of rice afforded a new γ-lactam (7) and a known γ-lactone (8) that were not detected in the former extracts. The structures of the new compounds were elucidated on the basis of 1D and 2D NMR spectra as well as by HRESIMS data. Compounds 1 and 4 exhibited significant cytotoxicity against the L5178Y mouse lymphoma cell line with IC50 values of 4.1 and 0.1 µM, respectively. Compound 4 also displayed cytotoxicity against the A2780 human ovarian cancer cell line with an IC50 value of 3.5 µM. The preliminary structure-activity relationships are discussed.

Abstract
Among flavonoid derivatives, tiliroside is a flavonoid contained in several edible plants or specific plant parts (fruits, leaves, or roots). These parts are often widely used as both food and medicines, in the treatment of various ailments and, in some cases, as food supplements. Considering the easy access to many publications concerning tiliroside and the lack of a review that summarizes the current progress in studies on its safety, efficacy, and presence in the plant kingdom, we present here a review paper on tiliroside and its principal derivatives. The paper also highlights the basic knowledge regarding this molecule, its derivatives, and the analytical approaches used for extraction and quantification, as well as reports on the biological activities against different key enzymes linked to various human diseases. The reported information is also devoted to highlighting the concept "learn from nature to discover new products," particularly in the development of new drugs, food supplements, and nutraceuticals, starting from a natural lead compound such as tiliroside and improving its biological activities (and selectivities) against a specific target for therapeutic purposes.

Abstract
The family Sterculiaceae is one of the most important families among flowering plants. Many of its members demonstrate medicinal properties and have been used for the treatment of various ailments and wounds. A wide range of compounds including alkaloids, phenyl propanoids, flavonoids, terpenoids and other types of compounds including hydrocarbons, sugars, quinones, phenolic acids, lactones, lignans, amine and amides have been isolated from several species in this family. Few studies have reported that some extracts and single compounds isolated from this family exhibited several biological activities, such as antimicrobial, anti-inflammatory, antioxidant and cytotoxic activities. The present review is an effort to provide information about the traditional uses, phytochemistry and pharmacology of species from family Sterculiaceae, and to uncover the gaps and potentials requiring further research opportunities regarding the chemistry and pharmacy of this family.

Abstract
Background Osteoporosis is one of the prevalent diseases in ageing populations. Due to side effects of many chemotherapeutic agents, there is always a need to search for herbal products to treat the disorder. Punica granatum (PG) represent a potent fruit-bearing medicinal herb which exerted valuable anti-osteoporotic activities. The present study was carried out to validate the in vitro osteogenic effects of the PG seed extract in primary calvarial osteoblast cultures harvested from neonatal rats. Methods The ethanolic extract of PG was subjected to evaluate cell proliferation, regeneration, mineralization and formation of collagen matrix using MTT, alkaline phosphatase, Alizarin Red-S staining and Sirius Red dye, respectively. Cell cycle progression and osteogenic gene Runx2 expression were carried out by flow cytometry and real time PCR, respectively. Results Exposure of different concentrations (10–100 μg/ml) of the extract on osteoblastic cells showed characteristic morphological changes and increment in cell number. A significant growth in cell proliferation, ALP activity, collagen contents and matrix mineralization of osteoblasts in a dose dependent manner (p < 0.05), suggested that PG has a stimulatory effect on osteoblastic bone formation or potential activity against osteoporosis. In addition, PG extract also enhanced DNA content in S phase of cell cycle and Runx2 gene expression level in osteoblasts. Conclusion The data clearly indicated that PG promoting bone cell proliferation and differentiation in primary osteoblasts might be due to elevating the osteogenic gene Runx2 expression. The present study provides an evidence for PG could be a promising herbal medicinal candidate that able to develop drugs for osteoporosis.

Abstract
The present study was designed to estimate the detailed antidiabetic activity of Pterospermum acerifolium (L.) Willd flowers. In vitro alpha amylase inhibition study was carried out on 50% ethanol extract of flowers (PAFEE) and its various fractions. The active ethyl acetate fraction (PAFEF) was subfractionated into three subfractions (PAFE1, PAFE2, and PAFE3) and subjected to acute toxicity studies followed by antidiabetic screening in vivo by streptozotocin-nicotinamide induced type II diabetes. Diabetic animals treated with PAFE2 (30 mg/kg) reduced the levels of fasting blood glucose, significantly (P < 0.001) compared to that of diabetic control animals. Histological studies on drug treated groups did not show remarkable positive changes in β-cells. PAFE2 showed 32.6 ± 1.93% glucose uptake over control and, in the presence of PI3K inhibitor wortmannin, declined to 13.7 ± 2.51%. HPLC analysis of PAFE2 reveals the presence of quercetin and apigenin as major constituents and both are inhibiting the glycogen phosphorylase enzyme in molecular modelling studies. The study evidenced strongly that the probable glucose lowering mechanism of action of active subfraction PAFE2 is by increasing the glucose uptake in peripheral tissues and by inhibition of gluconeogenesis.

Abstract
CONTEXT Pterospermum acerifolium (L.) Willd (Sterculiaceae) has been traditionally used in the treatment of diabetes mellitus but no scientific data has been published supporting the claimed ethnomedical use. OBJECTIVE The present study was designed to estimate the in silico, in vitro α-amylase inhibition potential and anti-diabetic activity of Pterospermum acerifolium bark. MATERIALS AND METHODS In silico studies were performed between human pancreatic α-amylase (HPA) and β-sitosterol by using autodock 4.2 software. In vitro α-amylase inhibition study was carried out with 50% ethanol extract of the bark (PABEE) and its various fractions. The active ethyl acetate fraction (PABEF) was sub-fractionated into three fractions (PABE1, PABE2 and PABE3). Two doses (15 and 30 mg/kg) based on acute toxicity studies, of the above fractions were subjected to antidiabetic screening in vivo by STZ-nicotinamide induced type II diabetic rats. RESULTS In silico studies showed the potent inhibition of β-sitosterol on human pancreatic amylase (HPA) with an estimated inhibition constant (Ki) of 269.35 nmol and two hydrogen bond interactions. PABEF showed marked α-amylase inhibition (69.94%) compared to other fractions. Diabetic rats treated with PABE3 (30 mg/kg) reduced the levels of fasting blood glucose, HbA1c, ALT, AST, ALP, triglycerides, total cholesterol, TBARS significantly (p < 0.01) and increased the levels of HDL-C, catalase, GSH, SOD significantly (p < 0.01) as compared to that of diabetic control animals. Histological studies on PABE3 treated group showed remarkable positive changes in β-cells. CONCLUSION The present study confirmed the antihyperglycemic activity along with its status on hepatic biomarkers, antihyperlipidemic and antioxidant properties of Pterospermum acerifolium bark.

Phytoceramides and acylated phytosterol glucosides from Pterospermum acerifolium Willd. seed coat and their osteogenic activity. PHYTOCHEMISTRY 2012; 81:117-125. [PMID: 22784550 DOI: 10.1016/j.phytochem.2012.06.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2012] [Revised: 05/18/2012] [Accepted: 06/11/2012] [Indexed: 06/01/2023]
Abstract
Phytochemical investigation of seed coats of Pterospermum acerifolium afforded two phytoceramides (1, 2) and two acylated phytosterol glucosides (3, 4) together with five known compounds (5-9). Their structures were elucidated on the basis of extensive spectroscopic analysis using 1D, 2D NMR and Mass spectrometry. Compounds 1, 2, 3, and 4 were assessed for their osteogenic activity using primary cultures of osteoblasts harvested from neonatal rat calvaria. Among these compounds, 1 and 2 markedly stimulated osteoblast differentiation assessed by alkaline phosphatase production and osteoblast mineralization by alizarin red-S staining.

JOURNAL OF ETHNOPHARMACOLOGY 2012; 141:331-337. [PMID: 22414477 DOI: 10.1016/j.jep.2012.02.041] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/14/2011] [Revised: 02/02/2012] [Accepted: 02/26/2012] [Indexed: 05/31/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Elephantopus mollis, Spilanthes africana, Urena lobata, Momordica multiflora, Asystasia gangetica and Brillantaisia ovariensis are used in Cameroonian traditional medicine for the treatment of bone diseases and fracture repair. The aim of this study was to evaluate the effect of ethanolic extracts of six Cameroonian medicinal plants on bone regeneration following bone and marrow injury. MATERIALS AND METHODS Ethanol extract of Cameroonian medicinal plants were administered (each extract at 250, 500 and 750mg/kg doses) orally to adult female Sprague-Dawley rats having a drill hole injury (0.8mm) in the femur diaphysis. Vehicle (gum-acacia in distilled water) was given to the control group. After 12 days of treatment, animals were euthanized and femur bones collected. Confocal microscopy of fractured bone was performed to evaluate bone regeneration (calcein labeling). Only active plant extracts were used for further experiments. Thus, callus was analyzed by microcomputed tomography. Osteogenic effects of the extracts were evaluated by assessing mineralized nodules formation of bone marrow stromal cells and osteoblast recruitment at drill hole site by immunohistochemistry. RESULTS Ethanolic extract of the leaves and twigs of Elephantopus mollis (EM) and whole plant of Spilanthes africana (SA) dose-dependently stimulated bone regeneration at the drill hole site. EM at 250 and 750mg/kg doses and SA at 750mg/kg dose significantly increased mineral deposition compared to controls. Both extracts at 500 and 750mg/kg doses improved microarchitecture of the regenerating bone evident from increased bone volume fraction, trabecular thickness, trabecular number, and decreased trabecular separation and structure model index. EM and SA extracts increased the formation of mineralized nodules from the bone marrow stromal cells. In addition, EM and SA extracts increased osteoblast recruitment at the drill hole site evident from increased Runx-2 positive cells following their treatments compared to control. CONCLUSION Ethanolic extracts of EM and SA accelerate fracture repair in rats via stimulatory effects on osteoblast differentiation and mineralization, thereby justifying their traditional use.

Abstract
One new isoflavone glucoside, caviunin 7-O-[β-d-apiofuranosyl-(1→6)-β-d-glucopyranoside] (10) and a new itaconic derivative, (E)-4-methoxy-2-(3,4-dihydroxybenzylidene)-4-oxobutanoic acid (15) along with series of isoflavones and flavonols with their glucosides (1-9 and 11-14) and a lignan glucoside (16) were isolated from the ethanolic extract of Dalbergia sissoo leaves. The structures of these compounds were established on the basis of IR, UV, (1)H and (13)C NMR, DEPT, COSY, HSQC, HMBC and MS data. All compounds (1-16) were assessed for osteogenic activity in primary calvarial osteoblast cultures. Compounds 1-4 and 10 increased alkaline phosphatase activity and mineralization thus resulting in significant osteogenic activity.
