Li YP, Liu H, Zhao XC, Tang XL, Shan P, Zhang H. Rare flavanone-diarylheptanoid hybrids from Typha angustifolia shows anti breast cancer activity via activating TGF-β1/Smad signaling pathway. Eur J Med Chem 2024; 268:116220. [PMID: 38387332 DOI: 10.1016/j.ejmech.2024.116220] [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: 12/15/2023] [Revised: 01/31/2024] [Accepted: 02/05/2024] [Indexed: 02/24/2024]
Abstract
Four new flavanone-diarylheptanoid hetero dimers, typhatifolins A-D (1-4), were separated from the pollen of a widely distributed medicinal plant Typha angustifolia. Structures of these rare hybrids were elucidated by detailed interpretation of spectroscopic data, and their absolute configurations were determined on the basis of Mosher's method and ECD analyses. All the four compounds showed moderate to significant cytotoxicities against a panel of tumor cell lines with IC50 values ranging from 0.67 to 12.48 μM. Further in vitro antitumor evaluation for typhatifolin B (TTB, 2) on two breast cancer cells (4T1 and MDA-MB231) revealed that it could remarkably induce cell apoptosis and G0/G1 cycle arrest, as well as block cell migration and invasion. Mechanistically, TTB could exert its antitumor effect via activating the TGF-β1 (transforming growth factor beta 1) signaling pathway as evidenced by RNA-seq analysis and immunoblotting experiments, which was further corroborated by treating cancer cells with a TGF-β signaling inhibitor. Lastly, the in vivo anti breast cancer activity was demonstrated by applying the mixture of typhatifolins A-D to a preclinical animal model.

In Silico Discovery of Potential Inhibitors Targeting the RNA Binding Loop of ADAR2 and 5-HT2CR from Traditional Chinese Natural Compounds. Int J Mol Sci 2023; 24:12612. [PMID: 37628792 PMCID: PMC10454645 DOI: 10.3390/ijms241612612] [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: 07/01/2023] [Revised: 08/02/2023] [Accepted: 08/06/2023] [Indexed: 08/27/2023] Open
Abstract
Adenosine deaminase acting on RNA 2 (ADAR2) is an important enzyme involved in RNA editing processes, particularly in the conversion of adenosine to inosine in RNA molecules. Dysregulation of ADAR2 activity has been implicated in various diseases, including neurological disorders (including schizophrenia), inflammatory disorders, viral infections, and cancers. Therefore, targeting ADAR2 with small molecules presents a promising therapeutic strategy for modulating RNA editing and potentially treating associated pathologies. However, there are limited compounds that effectively inhibit ADAR2 reactions. This study therefore employed computational approaches to virtually screen natural compounds from the traditional Chinese medicine (TCM) library. The shortlisted compounds demonstrated a stronger binding affinity to the ADAR2 (<-9.5 kcal/mol) than the known inhibitor, 8-azanebularine (-6.8 kcal/mol). The topmost compounds were also observed to possess high binding affinity towards 5-HT2CR with binding energies ranging from -7.8 to -12.9 kcal/mol. Further subjecting the top ADAR2-ligand complexes to molecular dynamics simulations and molecular mechanics Poisson-Boltzmann surface area (MM/PBSA) calculations revealed that five potential hit compounds comprising ZINC000014637370, ZINC000085593577, ZINC000042890265, ZINC000039183320, and ZINC000101100339 had favorable binding free energies of -174.911, -137.369, -117.236, -67.023, and -64.913 kJ/mol, respectively, with the human ADAR2 protein. Residues Lys350, Cys377, Glu396, Cys451, Arg455, Ser486, Gln488, and Arg510 were also predicted to be crucial in ligand recognition and binding. This finding will provide valuable insights into the molecular interactions between ADAR2 and small molecules, aiding in the design of future ADAR2 inhibitors with potential therapeutic applications. The potential lead compounds were also profiled to have insignificant toxicities. A structural similarity search via DrugBank revealed that ZINC000039183320 and ZINC000014637370 were similar to naringin and naringenin, which are known adenosine deaminase (ADA) inhibitors. These potential novel ADAR2 inhibitors identified herein may be beneficial in treating several neurological disorders, cancers, viral infections, and inflammatory disorders caused by ADAR2 after experimental validation.

Abstract
Tetrahydropyranones are synthesized from 3-bromobut-3-en-1-ols and aldehydes in good yields with excellent diastereoselectivity at -35 °C. The reaction involves an initial formation of a most stable six-membered chairlike tetrahydropyranyl carbocation followed by nucleophilic attack of the hydroxyl group and subsequent elimination of HBr to give tetrahydropyranone. The carbonyl moiety of the tetrahydropyranone is converted to enol ether and esters using Wittig reaction. It is also transformed into 4-hydroxy-2,6-disubstituted tetrahydropyran with 2,4- and 4,6-cis configuration by lithium aluminum hydride in up to 96% diastereoselectivity. Furthermore, the methodology is extended toward the synthesis of novel anticancer aminoguanidine compounds.

Abstract
The EtOH extracts of the dried seeds of Alpinia katsumadai were revealed with hypoglycemic effects on db/db mice at the concentration of 200 mg/kg. In order to clarify the antidiabetic constituents, 16 new diarylheptanoid-chalcone hybrids, katsumadainols A1-A16 (1-16), together with 13 known analogues (17-29), were isolated from A. katsumadai under the guidance of bioassay. Most of the compounds showed α-glucosidase and PTP1B dual inhibition, among which compounds 1-3, 5-7, 11-14, 21-25, and 27 showed PTP1B/TCPTP selective inhibition with IC50 values ranging from 22.0 to 96.7 μM, which were 2-10 times more active than sodium orthovanadate (IC50, 215.7 μM). All compounds exhibited obvious inhibition against α-glucosidase with IC50 values of 2.9-29.5 μM, indicating 6-59 times more active than acarbose (IC50, 170.9 μM). Study of enzyme kinetics indicated compounds 1, 3, and 12 were PTP1B and α-glucosidase mixed-type inhibitors with Ki values of 13.1, 12.9, 21.6 μM, and 4.9, 7.4, 3.4 μM, respectively.

Abstract
A new strategy is described for the direct conversion of unsaturated 3,5-dihydroxy-diarylheptanoids to dimeric products assembled on trans-2,8-dioxabicyclo[4.4.0]decane frameworks. The key atom-economical acid-mediated coupling creates 2 rings and 4 new stereocenters in a single-pot process. Oxygen-18 labeling studies are in accord with reactions proceeding via a cascade mechanism involving carbocationic intermediates. This approach enabled the concise total syntheses of analogues of the natural product blepharocalyxin D in 4 steps from simple starting materials.

Abstract
A series of 3-N-aryl substituted-2-heteroarylchromones was efficiently synthesized via Pd-mediated oxidative coupling under the influence of hetero-atoms neighboring group participation. Synthesized molecules were evaluated against human microtubule affinity regulating kinase 4 (MARK4) enzyme inhibitors, a recently identified anti-cancer drug target. Among 21 synthesized molecules, compounds 2, 3, and 14 exhibited excellent in vitro inhibitory effect against MARK4 with IC50 value (50% of ATPase activity) at 2.12 ± 0.22 μM, 1.98 ± 0.34 μM and 5.56 ± 0.42 μM respectively. The fluorescence binding and dot blot assay of these compounds were found in μM range, indicating a better binding affinity. In vitro study of these compounds against cancerous cells (MCF-7 and HepG2) inhibited the cell viability, induced apoptosis and lowered the tau-phosphorylation. Cell viability studies of compounds 2, 3, and 14 showed inhibition of cancerous cells growth with IC50 values of 3.22 ± 0.42, 4.32 ± 0.23 μM and 16.22 ± 1.33 μM for human breast cancer cells (MCF-7) and 6.45 ± 1.12, 5.22 ± 0.72 μM and 19.12 ± 1.43 μM for human liver carcinoma cells (HepG2) respectively. ROS quantification of these compounds showed oxidative stress to cancerous cells and molecular docking study showed hydrogen bonding, charge or polar and van der Waals interactions with the active site residues of MARK4. Owning to high binding fit nicely in the active site, offering the possibilities to be used as novel therapeutic molecules in the drug discovery against MARK4-related diseases.

Abstract
Microencapsulation of polyherbal formulation (PHF) extract was carried out by freeze drying method, by employing gum arabic (GA), gelatin (GE), and maltodextrin (MD) with their designated different combinations as encapsulating wall materials. Antioxidant components (i.e., total phenolic contents (TPC), total flavonoids contents (TFC), and total condensed tannins (TCT)), antioxidant activity (i.e., DPPH, β-carotene & ABTS⁺ assays), moisture contents, water activity (aw), solubility, hygroscopicity, glass transition temperature (Tg), particle size, morphology, in vitroα-amylase and α-glucosidase inhibition and bioavailability ratios of the powders were investigated. Amongst all encapsulated products, TB (5% GA & 5% MD) and TC (10% GA) have proven to be the best treatments with respect to the highest preservation of antioxidant components. These treatments also exhibited higher antioxidant potential by DPPH and β-carotene assays and noteworthy for an ABTS⁺ assays. Moreover, the aforesaid treatments also demonstrated lower moisture content, aw, particle size and higher solubility, hygroscopicity and glass transition temperature (Tg). All freeze dried samples showed irregular (asymmetrical) microcrystalline structures. Furthermore, TB and TC also illustrated the highest in vitro anti-diabetic potential due to great potency for inhibiting α-amylase and α-glucosidase activities. In the perspective of bioavailability, TA, TB and TC demonstrated the excellent bioavailability ratios (%). Furthermore, the photochemical profiling of ethanolic extract of PHF was also revealed to find out the bioactive compounds.

Abstract
The domino aldol/hetero-Diels-Alder synthesis of some new tricyclic pyrano[3,4-c]chromene derivatives has been achieved successfully after assembling a variety of acyclic or cyclic monoketones with prenyl ether-tethered aldehydes in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene in glycerol at 120 °C. The hitherto unreported stereochemical outcome of this synthetic sequence was studied and established on the basis of single-crystal X-ray diffraction data and 2D NMR NOESY spectroscopy along with the isolation and characterization of the intermediate Aldol condensation product.

Abstract
Twenty-nine phenolic compounds were isolated from the root bark of fresh (Yunnan) ginger and their structures fully characterized. Selected compounds were divided into structural categories and twelve compounds subjected to in-vitro assays including DPPH radical scavenging, xanthine-oxidase inhibition, monoamine oxidase inhibition, rat-brain homogenate lipid peroxidation, and rat pheochromocytoma PC12 cell and primary liver cell viability to determine their antioxidant and cytoprotective properties. Isolated compounds were also tested against nine human tumor cell lines to characterize anticancer potency. Several diarylheptanoids and epoxidic diarylheptanoids were effective DPPH radical scavengers and moderately effective at inhibiting xanthine oxidase. An enone-dione analog of 6-shogaol (compound 2) was isolated and identified to be most effective at protecting PC12 cells from H₂O₂-induced damage. Almost all tested compounds inhibited lipid peroxidation. Three compounds, 6-shogaol, 10-gingerol and an enone-diarylheptanoid analog of curcumin (compound 6) were identified to be cytotoxic in cell lines tested, with KB and HL60 cells most susceptible to 6-shogaol and the curcumin analog with IC₅₀<10 μM. QSAR analysis revealed cytotoxicity was related to compound lipophilicity and chemical reactivity. In conclusion, we observed distinct compounds in fresh ginger to have biological activities relevant in diseases associated with reactive oxygen species.

Abstract
AIM OF STUDY The fruit of Alpinia oxyphylla, an herb commonly used in East Asian medicine, is variously used for the treatment of cancer and inflammatory conditions, which may possibly be mediated through anti-angiogenesis. This study aims to check for anti-angiogenic functions in the herb. MATERIALS AND METHODS The 95% ethanol extract and four subsequent fractions (n-hexane, ethyl acetate, n-butanol and aqueous fractions) of the fruit of A. oxyphylla were tested on zebrafish model by quantitative endogenous alkaline phosphatase assay; then the active fractions were further tested on wild type and Tg(fli1a:EGFP)y1 zebrafish embryos and human umbilical vein endothelial cells and tumor cell lines for the anti-angiogenic effects. RESULTS The n-hexane and ethyl acetate fractions showed anti-angiogenic potentials in both in vivo and in vitro models. CONCLUSIONS The use of A. oxyphylla for cancer and inflammation diseases may be partly due to its effects against vessel formation.

Abstract
Diarylheptanoids, natural products with a 1,7-diphenylheptane structural skeleton, are mainly distributed in the roots, rhizomes and bark of Alpinia, Zingiber, Curcuma and Alnus species. They have become of interest in natural product research over the past twenty years because of their remarkable anticancer, anti-emetic, estrogenic, antimicrobial and antioxidant activity. This paper compiles all 307 naturally occurring diarylheptanoids from 46 plants as reported in 137 references with their distributions, physiological activities and 13C-NMR spectral data.

Abstract
A diastereoselective synthesis of the tetrahydropyranochromene ring system common to several natural product isolates of Alpinia blepharocalyx is reported. We have shown that a stereochemical preference exists for a syn configuration between the anomeric aryl substituents, representative of the C-7 and C-7' substituents in the natural products. Further, our results show that stereocontrol is under kinetic control, and calculations suggest that a favorable pi-stacking interaction may be the source of this stereocontrol.

ETHNOPHARMACOLOGICAL RELEVANCE Alpinia officinarum Hance (Zingiberaceae) is an annual plant. Its rhizome has long been used as an anti-inflammatory, an analgesic, a stomachic and a carminative in traditional medicine. OBJECTIVE The aim of this study was to test the anti-inflammatory effects of Alpinia officinarum rhizomes on acute and chronic arthritis in SD rats. METHODS Alpinia officinarum rhizomes were extracted by refluxing using 80% ethanol. The fractions were prepared by the fractionation of ethyl acetate (EtOAc), n-butanol, and water. This extract was administrated to rats by peroral injection. Acute arthritis was induced by a subcutaneous injection of carrageenan into the hind paw of SD rats. Chronic arthritis was stimulated by a subcutaneous injection of complete Freund's adjuvant (CFA) into the hind paw of SD rats. The paw volume was measured using a plethysmometer, thermal hyperalgesia was tested using a thermal plantar tester, hyperalgesia was evaluated by ankle flexion evoked vocalizations, and the expression of c-Fos in the brain hippocampus was measured with the avidin-biotin-peroxidase technique. Nitric oxide (NO) production was evaluated on nitrite by a Griess assay in lipopolysaccharide (LPS)-induced murine macrophage RAW 264.7 cells. RESULTS An 80% ethanolic extract showed acute anti-inflammatory activity that it reduced the edema volume in carrageenan-stimulated arthritis and inhibited NO generation in LPS-induced RAW 264.7 cells. In addition, this extract showed chronic anti-rheumatic and analgesic activities by suppressing the swelling volume, by recovering the paw withdrawal latency, and by inhibiting the flexion scores in CFA-induced arthritis. Particularly, this medicine had potent meaningful effects on the second signal of the left hind paw in the form of an immunological reaction compared to its effects on the first signal in the right hind paw after the CFA treatment. This also shows an anti-psychiatric effect through control of the expression of the c-Fos protein of the brain hippocampus in CFA-stimulated arthritis. On the other hand, each fraction showed acute anti-inflammatory effects; the action of the EtOAc fraction may have resulted from the suppression of NO production. CONCLUSIONS Alpinia officinarum rhizomes may be viable therapeutic or preventive candidates for the treatment of acute and chronic arthritis.

Abstract
We have established the structure of (+)-epicalyxin F through chemical synthesis. An acid-promoted rearrangement of synthetic benzopyran 6 led to the identification of the natural product as (3S,5S,7R)-epicalyxin F (22). Comparison with NMR spectra and optical rotation of the natural product confirms our assignment, and the reassigned structure is compatible with the proposed biosynthetic pathway.
