Nat Prod Res 2024; 38:2453-2462. [PMID: 36803113 DOI: 10.1080/14786419.2023.2180505] [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: 08/26/2022] [Revised: 01/30/2023] [Accepted: 02/08/2023] [Indexed: 02/22/2023]
Abstract
Five sesquiterpenoids including 2α-hydroxyoplopanone (1), oplopanone (2), 1β,4β,6α-trihydroxy-eudesmane (3), 1β,4β,7α-trihydroxy-eudesmane (4) and bullatantriol (5) were isolated from Homalomena pendula. The structure of the previously reported compound, 5,7-diepi-2α-hydroxyoplopanone (1a), has been revised to 1 by the spectroscopic evidences (1D-/2D-NMR, IR, UV and HRESIMS) and by comparison between experimental and theoretical NMR data using DP4+ protocol. Furthermore, the absolute configuration of 1 was unambiguously assigned by ECD experiments. Compounds 2 and 4 displayed a potent ability to stimulate osteogenic differentiation of MC3T3-E1 cells at 4 µg/mL (by 123.74% and 131.07%, respectively) and 20 µg/mL (by 112.45% and 126.41%, respectively) whilst 3 and 5 did not show any activities. At 20 µg/mL, 4 and 5 significantly promoted the mineralization of MC3T3-E1 cells with values of 112.95% and 116.37%, respectively, whereas 2 and 3 were inactive. The results indicated that 4 could be an excellent component for anti-osteoporosis studies from the rhizomes of H. pendula.

Autophagy inhibition mediated by trillin promotes apoptosis in hepatocellular carcinoma cells via activation of mTOR/STAT3 signaling. NAUNYN-SCHMIEDEBERG'S ARCHIVES OF PHARMACOLOGY 2024; 397:1575-1587. [PMID: 37676495 DOI: 10.1007/s00210-023-02700-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2023] [Accepted: 08/29/2023] [Indexed: 09/08/2023]
Abstract
Apoptosis and autophagy have been shown to act cooperatively and antagonistically in self-elimination process. On the one side, apoptosis and autophagy can act as partners to induce cell death in a coordinated or cooperative manner; on the flip side, autophagy acts as an antagonist to block apoptotic cell death by promoting cell survival. Our previous research indicated that trillin could induce apoptosis of PLC/PRF/5 cells, but the effects of trillin on autophagy as well as its functional relationship to apoptosis have not been elucidated. Here, the running study aims to investigate the function and molecular mechanism of trillin on autophagy with hepatocellular carcinoma (HCC) cells. The objective of this study is to investigate the molecular mechanism of trillin on autophagy in HCC cells. Protein levels of autophagy markers beclin1, LC3B, and p62 were detected by western blotting. 6-Hydroxyflavone and stattic were used to test the role of trillin regulation of autophagy via serine threonine kinase (AKT)/extracellular-regulated protein kinases (ERK) 1/2/mammalian target of rapamycin (mTOR)/signal transducer and activator of transcription 3 (STAT3) signaling pathway. Flow cytometry was used to detect caspase 3 activity and apoptosis in PLC/PRF/5 cells treated with trillin for 24 h with or without rapamycin, stattic, and 6-hydroxyflavone. The protein level of autophagy marker beclin1 was decreased, whilst the protein level of p62 was significantly increased by trillin treatment, indicating trillin treatment led to inhibition of autophagy in HCC cells. Trillin treatment could reduce the protein levels of p-AKT and p-ERK1/2, but enhance the protein levels of mTOR and p-mTOR, suggesting that trillin could inhibit AKT/ERK rather than mTOR. The AKT/ERK activator 6-hydroxyflavone could reverse the loss of AKT and ERK1/2 phosphorylation induced by trillin, implying that trillin impairs autophagy through activated mTOR rather than AKT/ERK. STAT3 and p-STAT3 were significantly upregulated by the trillin treatment with an increase in dose from 0 to 50 μM, suggesting that autophagy inhibition is mediated by trillin via activation of STAT3 signaling. The STAT3 inhibitor stattic significantly reversed the increased STAT3 phosphorylation at tyrosine 705 induced by trillin. The mTOR signaling inhibitor rapamycin reversed the trillin-induced mTOR phosphorylation enhancement but exerted no effects on total mTOR levels, suggesting trillin treatment led to inhibition of autophagy in HCC cells through activating mTOR/STAT3 pathway. Furthermore, caspase 3 activities and the total rate of apoptosis were increased by trillin treatment, which was reversed by rapamycin, stattic, and 6-hydroxyflavone, proving that trillin promotes apoptosis via activation of mTOR/STAT3 signaling. Trillin induced autophagy inhibition and promoted apoptosis in PLC/PRF/5 cells via the activation of mTOR/STAT3 signaling. Trillin has the potential to be a viable therapeutic option for HCC treatment.

Abstract
This study analyzed the chemical composition and anti-osteoporosis activity of the n-hexane extract of Homalomena gigantea rhizome. Sixty compounds, representing 92.0% of the extract, were identified by gas chromatography-mass spectrometry. Linalool (15.3%), oplopanone (9.8%), ( Ε)-α-atlantone (5.6%), khusinol acetate (5.4%), bullatantriol (4.3%), and β-sitosterol (3.8%) were the main constituents. The anti-osteoporotic activity of the n-hexane extract was determined by measuring alkaline phosphatase (ALP) activity, collagen content, and the mineralization of MC3T3-E1 cells. At concentrations of 4.0 and 20.0 µg/mL, the n-hexane extract increased ALP activity by 8.2% and 23.7%, and increased collagen secretion by MC3T3-E1 cells by 114.9% and 112.4%, respectively. At 4 µg/mL, the extract significantly promoted the mineralization of MC3T3-E1 cells by as much as 133.2% compared to the negative control. These results suggested that H. gigantea rhizome contains a natural anti-osteoporotic compound.

Baicalein inhibits inflammatory response and promotes osteogenic activity in periodontal ligament cells challenged with lipopolysaccharides. BMC Complement Med Ther 2021; 21:43. [PMID: 33485352 PMCID: PMC7824944 DOI: 10.1186/s12906-021-03213-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 01/10/2021] [Indexed: 12/13/2022] Open
Abstract
Background Periodontitis is a chronic infection initiated by oral bacterial and their virulence factors, yet the severity of periodontitis is largely determined by the dysregulated host immuno-inflammatory response. Baicalein is a flavonoid extracted from Scutellaria baicalensis with promising anti-inflammatory properties. This study aims to clarify the anti-inflammatory and osteogenic effects of baicalein in periodontal ligament cells (PDLCs) treated with lipopolysaccharides (LPS). Methods Human PDLCs were incubated with baicalein (0–100 μM) for 2 h prior to LPS challenge for 24 h. MTT analysis was adopted to assess the cytoxicity of baicalein. The mRNA and protein expression of inflammatory and osteogenic markers were measured by real-time polymerase chain reaction (PCR), western blot and enzyme-linked immunosorbent assay (ELISA) as appropriate. Alkaline phosphatase (ALP) and Alizarin red S (ARS) staining were performed to evaluate the osteogenic differentiation of PDLCs. The expression of Wnt/β-catenin and mitogen-activated protein kinase (MAPK) signaling related proteins was assessed by western blot. Results MTT results showed that baicalein up to 100 μM had no cytotoxicity on PDLCs. Baicalein significantly attenuated the inflammatory factors induced by LPS, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), matrix metalloprotein-1 (MMP-1), MMP-2 and monocyte chemoattractant protein 1 (MCP-1) at both mRNA and protein level. Moreover, MAPK signaling (ERK, JNK and p38) was significantly inhibited by baicalein, which may account for the mitigated inflammatory response. Next, we found that baicalein effectively restored the osteogenic differentiation of LPS-treated PDLCs, as shown by the increased ALP and ARS staining. Accordingly, the protein and gene expression of osteogenic markers, namely runt-related transcription factor 2 (RUNX2), collagen-I, and osterix were markedly upregulated. Importantly, baicalein could function as the Wnt/β-catenin signaling activator, which may lead to the increased osteoblastic differentiation of PDLCs. Conclusions With the limitation of the study, we provide in vitro evidence that baicalein ameliorates inflammatory response and restores osteogenesis in PDLCs challenged with LPS, indicating its potential use as the host response modulator for the management of periodontitis.

Abstract
Background/aim Bone tumor is one of the major causes of tissue bone loss, particularly after performing surgical excision operation to bone lesion that needs to be replaced by biomaterials and ensure a complete filling of tissue-loss spaces. The purpose of our study was to produce a nanofiber-based bone graft scaffold to fill the gaps resulted from bone cancer treatment and also capable of carrying functional molecules that can play a major role in preventing further cancer growth at the targeted bone tissue. Materials and methods Electrospinning method was used in order to produce nanofibers from different kinds of polymers; Hyaluronic acid (HA), Polyethylene oxide (PEO) and Polyvinyl alcohol (PVA) blended with different concentrations of herbal antibiotic and anti cancer flavonoid molecules called Baicalein (BE). The morphological and chemical structures of scaffold samples were studied using Scanning Electron Microscope (SEM), Fourier Transform Infrared-spectroscopy (FT-IR) and Surface-enhanced Raman spectroscopy (SERS) Analysis. Results The results showed production of homogenous nanofibers-based scaffold (diameter between 80 nm and 470 nm) that contains the polymers used in the spinning process and the entrapped Baicalein molecules within the nanofiber structure. Conclusion It was concluded that successful formation of bone tissue mimicking scaffold can be achieved by using Electrospinning method that produces nonwoven nanofibers and at the same time can hold functional anticancer agent such as Baicalein, which may allow using these types of scaffold in bone cancer treatment procedures.

Abstract
Extra virgin olive oil is characterized by its high content of unsaturated fatty acid residues in triglycerides, mainly oleic acid, and the presence of bioactive and antioxidant compounds. Its consumption is associated with lower risk of suffering chronic diseases and unwanted processes linked to aging, due to the antioxidant capacity and capability of its components to modulate cellular signaling pathways. Consumption of olive oil can alter the physiology of mesenchymal stem cells (MSCs). This may explain part of the healthy effects of olive oil consumption, such as prevention of unwanted aging processes. To date, there are no specific studies on the action of olive oil on MSCs, but effects of many components of such food on cell viability and differentiation have been evaluated. The objective of this article is to review existing literature on how different compounds of extra virgin olive oil, including residues of fatty acids, vitamins, squalene, triterpenes, pigments and phenols, affect MSC maintenance and differentiation, in order to provide a better understanding of the healthy effects of this food. Interestingly, most studies have shown a positive effect of these compounds on MSCs. The collective findings support the hypothesis that at least part of the beneficial effects of extra virgin olive oil consumption on health may be mediated by its effects on MSCs.

Abstract
Novel biotinylated C-6 substituted flavones were synthesised by a one-step method that connects biotin to 6-hydroxyflavone and 6-aminoflavone by esterification and amidation of hydroxyl and amino groups, respectively. The obtained compounds, 6-O-biotinylflavone and 6-biotinylamidoflavone, are the bifunctional molecules composed of a flavone moiety as a fluorescent reporter and biotin as a cancer-targeting unit. Antiproliferative activity was evaluated using SRB assays in MCF-7, MCF-10A, HepG2, MDA-MB-231, 4T1, and Balb/3T3 cell lines. In vitro evaluation revealed that compounds with biotin moiety displayed better cell selectivity between the cancer and normal cells than the parental substrates. These results indicate that anticancer effect is not related to the position of biotin moiety, but it is related to the presence of ester or amide bond. 6-O-Biotinylflavone was more active than 6-hydroxyflavone against human breast (MDA-MB-231) and liver (HepG2) cancer cells with IC50 (concentration of tested agent that inhibits proliferation of the cell population by 50%) values equal to 78.5 ± 18.8 μM and 133.2 ± 14.2 μM, respectively. Non biotinylated 6-aminoflavone was more active than 6-biotinylamidoflavone against all tested cell lines, with IC50 values between 34.3 ± 9.1 μM (4T1) and 173.86 ± 24.3 μM (MCF-7).

Abstract
For millennia, in the different cultures all over the world, plants have been extensively used as a source of therapeutic agents with wide-ranging medicinal applications, thus becoming part of a rational clinical and pharmacological investigation over the years. As bioactive molecules, plant-derived polyphenols have been demonstrated to exert many effects on human health by acting on different biological systems, thus their therapeutic potential would represent a novel approach on which natural product-based drug discovery and development could be based in the future. Many reports have provided evidence for the benefits derived from the dietary supplementation of polyphenols in the prevention and treatment of osteoporosis. Polyphenols are able to protect the bone, thanks to their antioxidant properties, as well as their anti-inflammatory actions by involving diverse signaling pathways, thus leading to bone anabolic effects and decreased bone resorption. This review is meant to summarize the research works performed so far, by elucidating the molecular mechanisms of action of polyphenols in a bone regeneration context, aiming at a better understanding of a possible application in the development of medical devices for bone tissue regeneration.

Abstract
Osteoporosis is a common skeletal disorder, resulting from an imbalance in bone resorption relative to formation. Bone morphogenetic protein (BMP) is a key regulator in bone formation and osteoblastic differentiation. Hence, compounds that promote BMP expression may be suitable candidates for osteoporosis treatment. This study examined the effects of the traditional Chinese medicinal agent, Kuei-Lu-Er-Xian-Jiao (KLEXJ), on BMP-2 production in osteoblasts. We found that KLEXJ extract promoted osteoblastic differentiation marker ALP activity and increased BMP-2 production; pretreatment with PI3K and Akt inhibitors, or small interfering RNA (siRNA), reduced these effects. KLEXJ also enhanced PI3K and Akt phosphorylation. Treatment of osteoblastic cells with NF-κB inhibitors (TPCK or PDTC) markedly inhibited KLEXJ-enhancement of ALP activity and BMP-2 production. KLEXJ also significantly promoted p65 phosphorylation, while treatment with PI3K and Akt inhibitors antagonized KLEXJ-enhanced p65 phosphorylation. Thus, KLEXJ enhances ALP activity and BMP-2 production of osteoblasts through the PI3K/Akt/ NF-κB signaling pathway and hence may be suitable in the treatment of osteoporosis.

Abstract
This study aimed to preliminary investigate the role of activin receptor-like kinase (ALK) 5 as one of TGF-βR1 subtypes in bone turnover and osteoblastic differentiation induced by fluoride. We analyzed bone mineral density and the expression of genes related with transforming growth factor-β1(TGF-β1) signaling and bone turnover in rats treated by different concentrations of fluoride with or without SB431542 in vivo. Moreover, MTT assay, alkaline phosphatase staining, RT-PCR, immunocytochemical analysis and western blot analysis were used to detect the influence on bone marrow stem cells (BMSC) after stimulating by varying concentration of fluoride with or without SB431542 in vitro. The in vivo study showed SB431542 treatment affected bone density and gene expression of rats, which indicated TGF-β1 and ALK5 might take part in fluoride-induced bone turnover and bone formation. The in vitro study showed low concentration of fluoride improved BMSC cells viability, alkaline phosphatase activity, and osteocalcin protein expression which were inhibited by high concentration of fluoride. The gene expression of Runx2 and ALK5 in cells increased after low concentration fluoride treatment which was also inhibited by high concentration of fluoride. Fluoride treatment inhibited gene and protein expression of Samd3 (except 1 mgF-/L). Compared with fluoride treatment alone, cells differentiation was inhibited with SB431542 treatment. Moreover, the expression of Runx2, ALK5 and Smad3 were influenced by SB431542 treatment. In conclusion, this preliminary study indicated that fluoride regulated osteoblastic TGFβ1 signaling in bone turnover and cells differentiation via ALK5.

Abstract
Baicalein is an active flavonoid extracted from the root of Scutellaria baicalensis that has anticancer and anti-inflammatory properties; its effects on osteoblastic and angiogenic potential are controversial. The aim of this study was to investigate the effects of baicalein on odontoblastic differentiation and angiogenesis and the underlying mechanism in human dental pulp cells (HDPCs). Baicalein (1–10[Formula: see text][Formula: see text]M) had no cytotoxic effects and promoted alkaline phosphatase (ALP) activity, mineralization assayed by Alizarin Red-S staining, and the mRNA expression of marker genes, in a concentration-dependent manner. In addition, baicalein upregulated angiogenic factors and increased in vitro capillary-like tube formation. Moreover, baicalein upregulated bone morphogenetic protein (BMP)-2 mRNA and phosphorylation of Smad 1/5/8 and Wnt ligand mRNA, glycogen synthase kinase-3, and nuclear [Formula: see text]-catenin. The odontogenic and angiogenic effects of baicalein were abolished by the BMP antagonist noggin and the Wnt/[Formula: see text]-catenin receptor antagonist DKK-1. These results demonstrate that baicalein promoted odontoblastic differentiation and angiogenesis of HDPCs by activating the BMP and Wnt/[Formula: see text]-catenin signal pathways. Our findings suggest that baicalein may contribute to dental pulp repair and regenerative endodontics.

Abstract
BACKGROUND Clinical evidence indicates the diabetes-induced impairment of osteogenesis caused by a decrease in osteoblast activity. Flavonoids can increase the differentiation and mineralization of osteoblasts in a high-glucose state. However, some flavonoids such as luteolin may have the potential to induce cytotoxicity in osteoblast-like cells. This study was performed to investigate whether a cytoprotective concentration range of luteolin could be separated from a cytotoxic concentration range in human MG-63 osteoblast-like cells in high-glucose condition. METHODS Cells were cultured in a normal- or high-glucose medium. Cell viability was determined with the MTT assay. The formation of intracellular reactive oxygen species (ROS) was measured using probe 2',7' -dichlorofluorescein diacetate, and osteogenic differentiation was evaluated with an alkaline phosphatase bioassay. RESULTS ROS generation, reduction in alkaline phosphatase activity, and cell death induced by high glucose were inhibited by lower concentrations of luteolin (EC50, 1.29±0.23 µM). Oxidative stress mediated by high glucose was also overcome by N-acetyl-L-cysteine. At high concentrations, luteolin caused osteoblast cell death in normal- and high-glucose states (IC50, 34±2.33 and 27±2.42 µM, respectively), as represented by increased ROS and decreased alkaline phosphatase activity. CONCLUSION Our results indicated that the cytoprotective action of luteolin in glucotoxic condition was manifested in much lower concentrations, by a factor of approximately 26 and 20, than was its cytotoxic activity, which occurred under normal or glucotoxic condition, respectively.
