Abstract
Background: Prostate cancer and non-small cell lung cancer (NSCLC) present significant challenges in the development of effective therapeutic strategies. Hormone therapies for prostate cancer target androgen receptors and prostate-specific antigen markers. However, treatment options for prostatic small-cell neuroendocrine carcinoma are limited. NSCLC, on the other hand, is primarily treated with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors but exhibits resistance. This study explored a novel therapeutic approach by investigating the potential anticancer properties of vitekwangin B, a natural compound derived from Vitex trifolia. Methods: Vitekwangin B was chromatographically isolated from the fruits of V. trifolia. ANO1 protein levels in prostate cancer and NSCLC cells were verified and evaluated again after vitekwangin B treatment. Results: Vitekwangin B did not inhibit anoctamin1 (ANO1) channel function but significantly reduced ANO1 protein levels. These results demonstrate that vitekwangin B effectively inhibited cancer cell viability and induced apoptosis in prostate cancer and NSCLC cells. Moreover, it exhibited minimal toxicity to liver cells and did not affect hERG channel activity, making it a promising candidate for further development as an anticancer drug. Conclusion: Vitekwangin B may offer a new direction for cancer therapy by targeting ANO1 protein, potentially improving treatment outcomes in patients with prostate cancer and NSCLC. Further research is needed to explore its full potential and overcome existing drug resistance challenges.

Abstract
Aphanapolystachones A-C (1-3), three undescribed sesquiterpene-diterpene heterodimers, were obtained from the fruits of Aphanamixis polystachya. Their structures and absolute configurations were identified by extensive analysis of HR-ESI-MS, NMR, experimental and TD-DFT calculated ECD spectra. The biosynthetic pathway of them was also proposed, which is produced by key intermolecular Diels-Alder [4 + 2]-cycloaddition reaction between a guaiane sesquiterpene and an acyclic diterpene. Compounds 1-3 inhibited NO production in LPS activated RAW 264.7 cells with the IC50 values of 1.7 ± 0.2, 3.0 ± 0.3, 5.3 ± 0.3 μM, respectively, lower than that of the positive control L-NMMA (31.5 ± 2.6 μM). In addition, compounds 1-3 significantly reduced IL-6 secretion at diluted concentration of 0.4 μM.

Abstract
Phytochemical study on the methanol extract of the stems and leaves of Kadsura induta led to the isolation of six dibenzocyclooctadiene lignans, including three new compounds named kadsindutalignans A-C (1-3), and three known ones, heteroclitalignan B (4), kadsuphilin C (5) and kadsulignan E (6). Their structures were elucidated based on extensive spectroscopic analyses, including HRESIMS, 1D- (1H NMR and 13C NMR), 2D-NMR (HSQC, HMBC, 1H-1H COSY and NOESY), and experimental circular dichroism (CD) spectra. All the isolates inhibited NO production in LPS-activated RAW264.7 cells with IC50 values in the range from 5.67 ± 0.54 µM to 38.19 ± 2.03 µM, compared to that of the positive control of NG-monomethyl-L-arginine acetate (L-NMMA) with an IC50 value of 8.90 ± 0.48 µM. Interestingly, the new compound 2 showed potential inhibition of NO production with an IC50 value of 5.67 ± 0.54 µM, which was higher than that of the positive control.

Abstract
A phytochemical study of the aerial parts of Piper mutabile C. DC. revealed seven undescribed compounds [two (2-7')-neolignans and five polyoxygenated cyclohexene glycosides] and six known propenylcatechol derivatives. The chemical structures of the isolated compounds were elucidated by extensive HR-ESI-MS and NMR analyses, as well as comparison with the literature. The absolute configurations of the (2-7')-neolignans were confirmed by GIAO 13C NMR calculations with a sorted training set strategy and TD-DFT calculation ECD spectra. The (2-7')-neolignans and polyoxygenated cyclohexene glycosides are unusual in natural sources. Undescribed neolignans 1 and 2 inhibited NO production in RAW 264.7 cells, with respective IC50 values of 14.4 and 9.5 μM.

Abstract
Plants of the Schisandra genus are commonly used in folk medicinal remedies. Some Schisandra species and their lignans have been reported to improve muscle strength. In the present study, four new lignans, named schisacaulins A-D, together with three previously described compounds ananonin B, alismoxide, and pregomisin were isolated from the leaves of S. cauliflora. Their chemical structures were determined by extensive analyses of HR-ESI-MS, NMR, and ECD spectra. Schisacaulin D and alismoxide significantly stimulated skeletal muscle cell proliferation by increasing the number of fused myotubes and expression of myosin heavy chain (MyHC) which may be good candidates for the treatment of sarcopenia.

Abstract
Five new flavonoid C-glycosides named desmodinosides A-E (1-5) and one known compound, apigenin 6-C-β-d-xylopyranosyl-2''-O-β-D-glucopyranoside (6) have been isolated from the methanol extract of the aerial parts of Desmodium heterocarpon var. stigosum. These compounds were determined by 1D and 2D-NMR and HR-MS spectroscopies. The methanol extract of this plant, in particular, demonstrated hepatoprotection and antifungal inhibition. This extract has a remarkable hepatoprotection and activity-dose response with an EC50 of 43.07 μg/mL. The hepatoprotective effect on human liver hepatoma cells (HepG2) of the isolated flavonoid C-glycosides 1-6 was observed. Desmodinosides A-C (1-3) were found to exhibit moderate hepatoprotective activity on HepG2 cells. Of these, compound 2 showed the best hepatoprotective activity with an EC50 value of 74.12 μg/mL. While compounds 1 and 3 displayed EC50 values of 271.21 and 211.99 μg/mL, respectively. Quercetin, a positive control, also caused an EC50 value of 36.42 μg/mL. In addition to having hepatoprotective effect, the methanol extract had an inhibitory effect on the growth of oomycete; it inhibited Phytophthora infestans with IC50 of 13.3 μg/mL and IC90 of 78.7 μg/mL. The oomycete inhibition was directly attributed to compounds 5 and 6, which significantly inhibited P. infestans with IC50 values of 27.4 and 24.7 μg/mL, respectively. Both 5 and 6 and methanol extract were active against P. infestanse in a dose-dependent manner. Our study demonstrated for the first time the new flavonoid C-glycosides from D. heterocarpon var. stigosum and their novel pharmacological properties. The study findings also suggest the plant extract and its metabolites could be used as a new botanical source of bioactive compounds.

Abstract
A phytochemical investigation of the methanolic extract of aerial parts of the Acanthus ilicifolius led to the isolation of two new lignan glycosides, acaniliciosides A and B (1 and 2), together with ten known compounds (3-12). The structures of isolated compounds were elucidated based on HR-ESI-MS, 1D and 2D NMR spectroscopic data. The absolute configurations of two new compounds were established by CD spectra. With the exception of compound 12, other compounds inhibited NO production in LPS activated RAW264.7 cells with IC50 values of 2.14-28.18 µM, as potent as that of the positive control of NG-monomethyl-L-arginine acetate (L-NMMA, IC50 of 32.50 µM). In addition, compounds 5-8 showed cytotoxic effects against SK-LU-1 and HepG2 cell lines with the IC50 values ranging from 16.48 to 76.40 μM compared to the positive control (ellipticine) with the IC50 values ranging from 1.23 to 1.46 μM.

Abstract
Anoctamin 1 (ANO1), a drug target for various cancers, including prostate and oral cancers, is an intracellular calcium-activated chloride ion channel that plays various physiopathological roles, especially in the induction of cancer growth and metastasis. In this study, we tested a novel compound isolated from Schisandra sphenanthera, known as schisandrathera D, for its inhibitory effect on ANO1. Schisandrathera D dose-dependently suppressed the ANO1 activation-mediated decrease in fluorescence of yellow fluorescent protein; however, it did not affect the adenosine triphosphate-induced increase in the intracellular calcium concentration or forskolin-induced cystic fibrosis transmembrane conductance regulator activity. Specifically, schisandrathera D gradually decreased the levels of ANO1 protein and significantly reduced the cell viability in ANO1-expressing cells when compared to those in ANO1-knockout cells. These effects could be attributed to the fact that schisandrathera D displayed better binding capacity to ANO1 protein than the previously known ANO1 inhibitor, Ani9. Finally, schisandrathera D increased the levels of caspase-3 and cleaved poly (ADP-ribose) polymerase 1, thereby indicating that its anticancer effect is mediated through apoptosis. Thus, this study highlights that schisandrathera D, which reduces ANO1 protein levels, has apoptosis-mediated anticancer effects in prostate and oral cancers, and thus, can be further developed into an anticancer agent.

Abstract
BACKGROUND Elevated activity of osteoclasts (OCs) is linked to osteolytic bone diseases, such as osteoporosis and rheumatoid arthritis. Developing natural anti-osteoclastogenic compounds with greater efficacy and fewer adverse effects is crucial for preventing or treating osteolytic bone diseases. N-triterpene cycloartane saponins (NTCSs) are rarely found in nature, and their inhibitory effects on OC differentiation in vitro and in vivo have not yet been explored. PURPOSE This study was aimed to investigate the effect of mussaendoside O, an NTCS isolated from Mussaenda pubescens, on RANKL-induced OC differentiation and its underlying mechanism in vitro, and lipopolysaccharide (LPS)-induced bone resorption in a mouse model. METHODS The content of mussaendoside O in methanol extract of M. pubescens was determined by HPLC. The inhibitory effects of mussaendoside O on RANKL-induced OC formation were assessed using TRAP staining, western blotting, immunofluorescence staining, and real-time qPCR. Meanwhile, the effects of mussaendoside O on LPS-induced inflammatory responses were assessed using a Griess reagent and qPCR. The effects of mussaendoside O on LPS-induced bone resorption in a mouse model were evaluated using micro-CT and immunohistochemical staining. RESULTS Mussaendoside O inhibited RANKL-induced TRAP-positive multinucleated OC formation in a concentration-dependent manner without affecting cell viability. However, mussaendoside O did not inhibit LPS-induced mRNA expression of COX-2, iNOS, and TNF-α. Mice orally administrated with mussaendoside O exhibited significant protection from LPS-induced bone resorption and OC formation. At the molecular level, mussaendoside O suppressed RANKL-activated phosphorylation of p38 MAPK and JNK, as well as c-Fos expression. In addition, mussaendoside O suppressed RANKL-induced NFATc1 activation and the expression of its target genes, including OSCAR, DC-STAMP, CtsK, and TRAP. CONCLUSION Mussaendoside O attenuates OC differentiation in vitro and LPS-induced bone resorption in a mouse model by inhibiting the RANKL-activated c-Fos/NFATc1 signaling pathways. Therefore, mussaendoside O may be a valuable lead compound for preventing or treating of osteolytic bone diseases.

Abstract
Bone homeostasis is maintained by a combination of osteoclast-mediated bone resorption and osteoblast-mediated bone formation. Excessive osteoclast activity is linked to several bone-related disorders, including osteoporosis and rheumatoid arthritis. Pharmacological therapy might have a number of adverse effects. Therefore, the development of natural anti-osteoclastogenic drugs with greater efficacy and fewer adverse effects is desirable. In this study, the anti-osteoclastogenic effects of 23-hydroxyursolic acid (HUA), a triterpene isolated from Viburnum lutescens, were investigated in vitro and in vivo. HUA significantly inhibited receptor activator of nuclear factor kappa-B ligand (RANKL)-induced mature osteoclast differentiation by reducing the number of tartrate-resistant acid phosphatase (TRAP)-positive osteoclasts and F-actin ring formation. It also inhibited the expression of osteoclast-specific marker genes such OSCAR, MMP-9, TRAP, DC-STAMP, and CtsK, as well as transcription factors, c-Fos and nuclear factor of activated T cells cytoplasmic 1 (NFATc1) in response to RANKL. Mice orally administered with HUA (25 and 50 mg/kg) exhibited significant protection against bone loss and osteoclast formation induced by lipopolysaccharide (LPS). HUA suppressed RANKL-induced nuclear factor kappa B (NF-κB) activation and phosphorylation of JNK and ERK mitogen-activated protein kinases (MAPKs). These results suggest that HUA attenuates osteoclast formation in vitro and in vivo by suppressing the RANKL-mediated AP1, NF-κB, and NFATc1 pathways. Therefore, HUA may be a lead compound for the prevention or treatment of osteolytic bone disorders.

Abstract
A new phenylpropane (1) and 9 known (2-10) compounds were isolated from the methanol extract of Pandanus tonkinensis roots. Their chemical structures were determined as (7 S)-2,6-dimethoxyphenyl-7,9-propanediol-1 -O-β-D-glucopyranoside (1), isorhapontigenin (2), pinoresinol-4,4′-di -O-β-D-glucoside (3), isoeucommin A (4), pinoresinol-4′ -O-β-D-glucoside (5), acanthoside B (6), eucommin A (7), urolignoside (8), benzyl O-α-L-arabinopyranosyl-(1→6) -β-D-glucopyranoside (9), and (6 S,9 S)-roseoside (10) by comprehensive analysis of high-resolution electron spray ionization mass spectrum and nuclear magnetic resonance spectral data, as well as by comparison of their spectral data with those reported in the literature. In addition, the stereochemistry of 1 was successfully determined by both theoretical and calculated CD spectra. All the isolates were tested for their lipid peroxidation inhibitory effects by in vitro assay. Compounds 2-7 exhibited significantly lipid peroxidation inhibitory effects with IC50 values of 21.3 ± 1.7, 61.9 ± 3.9, 57.5 ± 5.5, 10.4 ± 0.7, 28.9 ± 0.3, 54.2 ± 3.5 µM, respectively, compared to that of the positive control, trolox (31.4 ± 2.2 µM).

Abstract
Five new dibenzocyclooctadiene lignans, named kadsuindutains A–E (1–5), and three known ones schizanrin F (6), schizanrin O (7), and schisantherin J (8) were isolated from the stems of Kadsura induta. Their structures were determined by analyses of HR-ESI-MS, NMR, and ECD spectra. Compounds 1–5 contain a 2′,4′-dioxygenated-2′,3′-dimethylbutyryl moiety which is rarely reported for dibenzocyclooctadiene lignans. Molecular docking predicted that compounds 1–8 displayed good binding affinity to the active site of iNOS and TNF-α proteins but unstable binding to the active site of COX-2 protein. Additionally, in vitro experiments showed that compounds 1–8 inhibited NO production in LPS-activated RAW264.7 cells with IC50 values from 10.7 μM to 34.0 μM, compared to the positive control L-NMMA (IC50 = 31.2 μM). Five new dibenzocyclooctadiene lignans isolated from the stems of Kadsura induta. Their anti-inflammatory activities were studied by molecular docking and inhibition of NO production in LPS activated-RAW264.7 cells.![]()

Abstract
The methanolic extract of Mussaenda pubescens Dryand leaves exhibited significant anti-osteoclastogenic activity. Chemical investigation of M. pubescens led to the isolation of one new cycloartane saponin, mussaendoside X (1) along with eight known compounds: heinsiagenin A 3-O-[α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)]-O-β-D-glucopyranoside (2), mussaendoside O (3), heinsiagenin A 3-O-[α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)]-O-β-D-glucopyranosyl-(1→4)-O-β-D-glucopyranoside (4), mussaendoside G (5), mussaendoside U (6), shanzhiside methyl ester (7), barlerin (8) and musaenoside (9). Their structures were elucidated by extensive spectroscopic methods including 1D- and 2D-NMR as well as MS analysis and comparison with the literature. Cycloartane saponins 1-6 positively suppressed osteoclast formation in an anti-osteoclastogenic screening assay. Consequently, treatment of RANKL-stimulated RAW 264.7 cells with compounds 1-4 significantly decreased the number of osteoclasts in a concentration-dependent manner. Six compounds from M. pubescens, with the new cycloartane, mussaendoside X, were shown for the first time as potential effective inhibitors of osteoclastogenesis.
