Abstract
Alzheimer's disease is one of the causes associated with the early stages of dementia. Nowadays, the main treatment available is to inhibit the actions of the acetylcholinesterase (AChE) enzyme, which has been identified as responsible for the disease. In this study, computational methods were used to examine the structure and therapeutic ability of chemical compounds extracted from Millettia brandisiana natural products against AChE. This plant is commonly known as a traditional medicine in Vietnam and Thailand for the treatment of several diseases. Furthermore, machine learning helped us narrow down the choice of 85 substances for further studies by molecular docking and molecular dynamics simulations to gain deeper insights into the interactions between inhibitors and disease proteins. Of the five top-choice substances, γ-dimethylallyloxy-5,7,2,5-tetramethoxyisoflavone emerges as a promising substance due to its large free binding energy to AChE and the high thermodynamic stability of the resulting complex.

Anticholinesterase Activity of Methanolic Extract of Amorpha fruticosa Flowers and Isolation of Rotenoids and Putrescine and Spermidine Derivatives. PLANTS (BASEL, SWITZERLAND) 2024; 13:1181. [PMID: 38732396 PMCID: PMC11085544 DOI: 10.3390/plants13091181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 04/15/2024] [Accepted: 04/19/2024] [Indexed: 05/13/2024]
Abstract
Five putrescine and spermidine derivatives (1-5) together with five rotenoids (6-10) were isolated from a methanolic extract of the flowers of A. fruticosa that displayed promising inhibition of 76.0 ± 1.9% for AChE and 90.0 ± 4.0% for BuChE at a concentration of 1 mg/mL. Although the anticholinesterase activities of the isolated compounds did not reach that of galantamine, molecular docking revealed that all-trans-tri-p-coumaroylspermidine and trans-trans-cis-tri-p-coumaroylspermidine showed binding poses mimicking the known inhibitor galantamine and thus could serve as model molecules in future searches for new AChE and BuChE inhibitors.

Abstract
Artemisia anomala S. Moore exerts many pharmacological activities, including the removing of the blood stasis, relieving of the fever and analgesia, reducing the swelling and dampness. In this study, the extraction technology, chemical compositions and anti-inflammatory effect in vitro and mechanism of total flavonoids extract from Artemisia anomala S. Moore were studied. The optimal yield rate of total flavonoids extract was optimized by single factor experiments and response surface method, and the chemical constituents were analyzed by UPLC-QTOF-MS method; and the anti-inflammatory activity of the extract was evaluated with lipopolysaccharide induced RAW 264.7 cells. The highest extraction rate was 2.02% under these conditions of the concentration of ethanol 50%, the ultrasonic extraction time 30 min, and the ratio of solvent volume to material weight 20:1 (ml/g). In addition, the main components of total flavonoid extract were preliminarily identified and deduced based on mass spectrometry information and relevant literatures, and its stronger anti-inflammatory activity was demonstrated by reducing the phagocytosis, the content of nitric oxide and the level of related cytokines (tumor necrosis factor-α, interleukin-10, interleukin-6). Furthermore, it was further revealed that the anti-inflammatory effect of the extract was closely connected with the activation of TLR4-MyD88-NF-κB signalling pathway. This study indicated that the total flavonoids extract from Artemisia anomala S. Moore may be a better candidate anti-inflammatory natural medicine.

Abstract
BACKGROUND M. pyrrhocarpa is a new plant in the Fabaceae: Faboideae family that is found in Thailand. A literature search revealed that the Milletia genus is rich in bioactive compounds possessing a wide range of biological activities. In this study, we aimed to isolate novel bioactive compounds and to study their bioactivities. METHODS The hexane, ethyl acetate, and methanol extracts from the leaves and twigs of M. pyrrhocarpa were isolated and purified using chromatography techniques. These extracts and pure compounds were tested in vitro for their inhibitory activities against nine strains of bacteria, as well as their anti-HIV-1 virus activity and cytotoxicity against eight cancer cell lines. RESULTS Three rotenoids, named 6aS, 12aS, 12S-elliptinol (1), 6aS, 12aS, 12S-munduserol (2), dehydromunduserone (3), and crude extracts were evaluated for antibacterial, anti-HIV, and cytotoxic activities. It was found that compounds 1-3 inhibited the growth of nine strains of bacteria, and the best MIC/MBC values were obtained at 3/ > 3 mg/mL. The hexane extract showed anti-HIV-1 RT with the highest %inhibition at 81.27 at 200 mg/mL, while 6aS, 12aS, 12S-elliptinol (1) reduced syncytium formation in 1A2 cells with a maximum EC50 value of 4.48 μM. Furthermore, 6aS, 12aS, 12S-elliptinol (1) showed cytotoxicity against A549 and Hep G2 cells with maximum ED50 values of 2.27 and 3.94 μg/mL. CONCLUSION This study led to the isolation of constituents with potential for medicinal application, providing compounds (1-3) as lead compounds against nine strains of bacteria. The hexane extract showed the highest %inhibition of HIV-1 virus, Compound 1 showed the best EC50 in reducing syncytium formation in 1A2 cells, and it also showed the best ED50 against human lung adenocarcinoma (A549) and human hepatocellular carcinoma (Hep G2). The isolated compounds from M. pyrrhocarpa offered significant potential for future medicinal application studies.

PHYTOCHEMISTRY REVIEWS : PROCEEDINGS OF THE PHYTOCHEMICAL SOCIETY OF EUROPE 2022; 22:275-308. [PMID: 36345415 PMCID: PMC9630821 DOI: 10.1007/s11101-022-09845-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 10/21/2022] [Indexed: 06/16/2023]
Abstract
UNLABELLED There are approximately 260 known species in the genus Millettia, many of which are used in traditional medicine to treat human and other animal ailments in various parts of the world. Being in the Leguminosae (Fabaceae) family, Millettia species are rich sources of isoflavonoids. In the past three decades alone, several isoflavonoids originating from Millettia have been isolated, and their pharmacological activities have been evaluated against major diseases, such as cancer, inflammation, and diabetes. Despite such extensive research, no recent and comprehensive review of the phytochemistry and pharmacology of Millettia isoflavonoids is available. Furthermore, the structural diversity of isoflavonoids in Millettia species has rarely been reported. In this review, we comprehensively summarized the structural diversity of Millettia isoflavonoids, the methods used for their extraction and isolation protocols, and their pharmacological properties. According to the literature, 154 structurally diverse isoflavonoids were isolated and reported from the various tissues of nine well-known Millettia species. Prenylated isoflavonoids and rotenoids were the most dominant subclasses of isoflavonoids reported. Other subclasses of reported isoflavonoids include isoflavans, aglycone isoflavones, glycosylated isoflavones, geranylated isoflavonoids, phenylcoumarins, pterocarpans and coumaronochromenes. Although some isolated molecules showed promising pharmacological properties, such as anticancer, anti-inflammatory, estrogenic, and antibacterial activities, others remained untested. In general, this review highlights the potential of Millettia isoflavonoids and could improve their utilization in drug discovery and medicinal use processes.

Abstract
A phytochemical investigation of the root and leaf extracts of Millettia pachycarpa Benth resulted in the isolation and identification of 16 compounds, including six rotenoids (1-6) and 10 prenylated isoflavonoids (7-16). Compound 4 was isolated as a scalemic mixture, which was resolved by chiral HPLC to afford (-)-(6aS,12aS)-12a-hydroxy-α-toxicarol (4) and (+)-(6aR,12aR)-12a-hydroxy-α-toxicarol (4). (+)-(6aR,12aR)-Millettiapachycarpin (3) and (-)-(6aS,12aS)-12a-hydroxy-α-toxicarol (4) were isolated as new compounds. The absolute configuration of (-)-(6R)-pachycarotenoid (2), (+)-(6aR,12aR)-millettiapachycarpin (3), (-)-(6aS,12aS)-4 and (+)-(6aR,12aR)-12a-hydroxy-α-toxicarol (4), (+)-(6aS,12aS)-(5), and (-)-(6aS,12aS,2″R)-sumatrol (6) were identified by electronic circular dichroism (ECD) data. (-)-(6aS,12aS,2″R)-Sumatrol (6) was also confirmed by X-ray diffraction analysis using Cu-Kα radiation. Antidiabetic activities, including α-glucosidase and α-amylase inhibitory activities, and cytotoxicities against lung cancer A549, colorectal cancer SW480, and leukemic K562 cells of some isolated compounds were evaluated. Of these, isolupalbigenin (11) exhibited the highest α-glucosidase inhibitory activity, with an IC50 value of 11.3 ± 0.2 μM, whereas the scalemic mixture of 12a-hydroxy-α-toxicarol (4) displayed the best α-amylase inhibitory activity, with an IC50 value of 106.9 ± 0.2 μM. Euchrenone b10 (15) exhibited the highest cytotoxicity against lung cancer A549, colorectal cancer SW480, and leukemic K562 cells, with IC50 values of 40.3, 39.1, and 15.1 μM, respectively. In addition, molecular docking simulations of α-glucosidase inhibition of the active compounds were studied.

Abstract
With respect to the unknowns of pathophysiology of Alzheimer's Disease (AD)-, and Parkinson's Disease (PD)-like neurodegenerative disorders, natural product research is still one of the valid tools in order to provide alternative and/or better treatment options. At one hand, various extracts of herbals provide a combination of actions targeting multiple receptors, on the other hand, the discovery of active natural products (i.e., secondary metabolites) generally offers alternative chemical structures either ready to be employed in clinical studies or available to be utilized as important scaffolds for the design of novel agents. Regarding the importance of certain enzymes (e.g. cholinesterase and monoamine oxidase B), for the treatment of AD and PD, we have surveyed the natural product research within this area in the last decade. Particularly novel natural agents discovered within this period, concomitant to novel biological activities displayed for known natural products, are harmonized within the present study.

Abstract
Peptide sequence modulates amyloid fibril formation and triggers Alzheimer's disease. The N-terminal region of amyloid peptide is disordered and lack any specific secondary structure. An ionic interaction of Aβ1-11 with factor XII is critical for the activation of the contact system in Alzheimer's disease. In this study, we report the self-assembly of fluctuating N-terminal Aβ1-11 into nanotubes using atomic force micrography, transmission electron microscopy, circular dichroism studies and molecular modeling studies. The effect of four polyphenols: baicalein, rutin, vanillin and cyanidin-3-O-glucoside (C3G) was also explored on the amyloid fibril inhibitor perspective using amyloid specific dye Thioflavin T (ThT). AFM micrographs suggested the self-assembly of Aβ1-11 into nanotubes after three weeks of incubation. Microwave treatment results in the conformational variation of disordered structure to β-sheet rich amyloid fibrils. The presence of salts (sodium and potassium chloride) induces the structural transformation of Aβ1-11 to super-helix. Fluorescence spectroscopy studies using ThT suggested differential inhibition of amyloid fibrils formation in the presence of polyphenols. Molecular modeling studies suggested that binding of polyphenols to Aβ1-11 through hydrophobic interaction (Phe4 and Tyr 10) and hydrogen bonding (Glu3 and Arg5) play a substantial role in stabilizing Aβ1-11-polyphenols complex. In the presence of polyphenols, Aβ1-11 transforms to hybrid nanostructures thus hindering amyloid fibril formation. These results provide structural insights and importance of the N-terminal residues in the Aβ1-42 self-assembly mechanism.

Abstract
Glycine tabacina (Labill.) Benth is an edible medicinal herb for rheumatoid arthritis (RA) treatment in folk medicine. Current phytochemical research on this dried herb led to the isolation of eight new coumestans, named glytabastan A-H (1-8), and twenty-three known compounds 9-31. Their structures were elucidated using spectroscopic methods. The antiarthritic activities of all isolates were evaluated, and the results showed that coumestans 1-6 and 8-10 could inhibit arthritic inflammation in vitro, while coumestans 1, 2, 9, and 10 significantly blocked the osteoclastogenesis induced by receptor activator of nuclear factor (NF) κB ligand (RANKL). Moreover, network pharmacological analysis revealed that the anti-RA effect of G. tabacina involved multitargets, multipathways such as PI3K/Akt and MAPK signaling pathways, and various biological processes such as inflammatory response and cytokine-mediated signaling pathways. These results suggested that this species and its novel coumestans could serve as potential antiarthritic agents for functional food or medicinal use.

Abstract
Natural products have extensively contributed toward the discovery of new leads for Alzheimer's disease. During our search for new inhibitors of cholinesterase enzymes from natural sources, the ethyl acetate (EtOAc) extract of Rumex abyssinicus Jacq was identified as a dual cholinesterase inhibitor with IC50 values of 2.7 and 11.4 μg/mL against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), respectively. The phytochemical investigation of the EtOAc extract has resulted in isolation of four anthraquinones, namely, helminthosporin, emodin, chrysophanol, and physcion, amongst which the helminthosporin has been isolated for the first time from Rumex sp. All isolated secondary metabolites have displayed significant inhibition of EeAChE with IC50 values of 2.63, 15.21, 33.7, and 12.16 μM, respectively. In addition, the helminthosporin was also found to inhibit BChE with an IC50 value of 2.99 μM. The enzyme kinetic study has indicated that helminthosporin inhibits AChE and BChE in a noncompetitive manner with k i values of 10.3 and 12.3 μM, respectively. The results of molecular modeling and propidium iodide displacement assay have revealed that helminthosporin occupies the peripheral anionic site of the active site gorge of AChE. In the PAMPA-BBB permeability assay, helminthosporin was found to possess high BBB permeability (P e = 6.16 × 10-6 cm/s). In a nutshell, helminthosporin has been identified as a brain permeable dual cholinesterase inhibitor, and thus its further synthetic exploration is warranted for optimization of its potency.
