Abstract
Natural products, remains the most important source for the discovery of new drugs for the treatment of human diseases. This has inspired the synthetic community to design and develop mimics of natural products either to answer important questions in biology or to explore their therapeutic potentials. Glycosides present themselves abundantly in nature, right from the cell surface receptors to natural products of any origin. The O-Glycosides are hydrolytically less stable compared to C-glycosides and this feature has presented a great opportunity for drug discovery. The discovery of Dapagliflozin, an SGLT inhibitor and C-glucoside, for the treatment of diabetes is one such example. Aryl acyl-anion chemistry has been explored for the synthesis of 2-deoxy-C-aryl furanoside/pyranoside/septanosides. Besides success, the studies have provided valuable insight into the natural propensities of the architectural framework for the cascade to furan derivatives. The aryl acyl-anion chemistry has also enabled the synthesis of biologically active diaryl heptanoids. Inspired from sucesss of Dapagliflozin, new analogues have been synthesized with pyridine and isocoumarin heterocycle as the proximal ring. C-glucosides of isoliquiritigenin have been synthesized for the first time and evaluated as an efficient aldose reductase inhibitor. The synthesis and evaluation of acyl-C-β-D-glucosides and benzyl-C-β-D-glucoside as glucose-uptake promoters has revealed promise in small molecules. The concept of building blocks has been used to obtain natural oxylipins, D-xylo and L-xylo-configured alkane tetrols and novel lipophilic ketones with erythro/threo configured trihydroxy polar head-group as possible anti-mycobacterial agents.

Abstract
Diabetes mellitus (DM) is characterized by hyperglycaemia, resulting from defects in insulin secretion, insulin action or both. There are several factors such as hyperlipidemia and oxidative stress (OS), namely the production of reactive oxygen/nitrogen species (ROS/RNS), that actively contribute to the development and worsening of DM. Chalcones, also termed as benzalacetophenone or benzylidene acetophenone, present a 1,3-diaryl-2-propen-1-one scaffold that has been shown to be highly promising in the development of new antioxidant compounds. Considering the potential interest of antioxidant therapy, the present review scrutinizes the role of the main sources of ROS/RNS production during DM. The modulatory effect of chalcones against nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, xanthine oxidase, mitochondrial respiratory chain and nitric oxide synthase, is also thoroughly discussed, establishing, whenever possible, a structure-activity relationship (SAR). From the SAR analysis, it can be stated that the presence of catechol groups, hydroxyl and methoxyl substituents in the chalcones scaffold improves their modulatory activity against the main sources of ROS/RNS production in DM.

Abstract
Outcomes of treatment for malignant pediatric tumors including leukemia are improving by conventional multimodal treatment with strong chemotherapy, surgical resection, radiotherapy, and bone marrow transplantation. However, patients with advanced neuroblastoma, metastatic Ewing's sarcoma family of tumor (ESFT), and metastatic osteosarcoma continue to have an extremely poor prognosis. Therefore novel therapeutic strategies are urgently needed to improve their survival. Apoptotic cell death is a key mechanism for normal cellular homeostasis. Intact apoptotic mechanisms are pivotal for embryonic development, tissue remodeling, immune regulation, and tumor regression. Genetic aberrations disrupting programmed cell death often underpin tumorigenesis and drug resistance. Moreover, it has been suggested that apoptosis or cell differentiation proceeds to spontaneous regression in early stage neuroblastoma. Therefore apoptosis or cell differentiation is a critical event in this cancer. We extracted many compounds from natural plants (Angelica keiskei, Alpinia officiarum, Lycaria puchury-major, Brassica rapa) or synthesized cyclophane pyridine, indirubin derivatives, vitamin K3 derivatives, burchellin derivatives, and GANT61, and examined their effects on apoptosis, cell differentiation, and cell cycle in neuroblastoma and ESFT cell lines compared with normal cells. Some compounds were very effective against these tumor cells. These results suggest that they may be applicable as an efficacious and safe drug for the treatment of malignant pediatric tumors.

Tricin Isolated from Enzyme-Treated Zizania latifolia Extract Inhibits IgE-Mediated Allergic Reactions in RBL-2H3 Cells by Targeting the Lyn/Syk Pathway. Molecules 2020; 25:molecules25092084.

Abstract
Tricin, a flavone present in rice bran, is confirmed as the major efficacious compound present in the enzyme-treated Zizania latifolia extract (ETZL), which protects against UVB-induced skin-aging. However, the suppressive mechanism of tricin on allergic responses remains unknown. The present study, therefore, aimed to determine the mechanisms of tricin and ETZL on mast cell degranulation in IgE-activated rat basophilic leukemia cell line (RBL-2H3) cells. We investigated the regulatory effects of tricin and ETZL on degranulation, production of cytokines and lipid mediators, and signaling proteins involved in the IgE-bound high-affinity IgE receptor activation, mitogen-activated protein kinase, arachidonic acid and Syk. The production of β–hexosaminidase, tumor necrosis factor-α, interleukin-4, leukotrienes (LT) B4, LTC4 and prostaglandin E2 in IgE-stimulated RBL-2H3 cells were significantly inhibited by exposure to tricin or ETZL. Moreover, tricin and ETZL inhibit the phosphorylation of cytosolic phospholipase A2, 5-lipoxygenase and cyclooxygenase-2. Furthermore, the phosphorylation of Akt, ERK, p38, JNK, protein kinase Cδ and phospholipase Cγ1 were effectively suppressed by both samples. Exposure to tricin or ETZL also significantly decreases the phosphorylation of Lyn and Syk, but has minimal effect on Fyn. Taken together, our data indicate that tricin and ETZL are potential anti-allergic materials that could be applied for the prevention of allergy-related diseases.

Abstract
Seven novel carbohydrate conjugates of new chalcone-3- O-glycosides were synthesized and characterized. Starting from the substituted 3′-hydroxyarylmethylacetophenone derivatives (chalcones) with α-acetobromoglucose in anhydrous acetone were synthesized 2,3,4,6-tetra- O-acetyl-3′- O-β-d-glucopyranosyloxychalcones. Deblocking the latter with CH3ONa in dry methanol results in substituted chalcone-3- O-glycosides (3′- O-β-d-glucopyranosyloxychalcones). The structures of the newly synthesized chalcone-3- O-glycosides were characterized based on1H nuclear magnetic resonance,13C nuclear magnetic resonance, mass spectroscopy, and Fourier-transform infrared spectroscopy.

Abstract
North-western Argentinean propolis (NAP), having promising bioactivity, was recently included into the National Food Code. Zuccagnia punctata Cav., a native shrub of north-western Argentina, is one of the prevalent botanical sources of NAPs, but no information on its allergenic constituents was available so far. A liquid chromatography-diode array detector -quadrupole-time of flight system (LC-DAD-QTOF) was used as a screening method for the reliable identification of sensitizing agents belonging to caffeic acid derivatives in Z. punctata and in two NAPs collected in the provinces of Catamarca and Tucumán. Caffeic acid phenethyl ester, one of the most active allergens in propolis, was never detected in either Z. punctata or NAP. Among 31 sensitizers, only geranyl caffeate was alleged in Z. punctata as <10% of its major constituent, whereas three caffeic acid derivatives with strong allergenic effect, i.e., geranyl, pentenyl, and benzyl caffeates, occurred in NAP samples (29%–36% of the Z. punctata major constituent), indicating other minor botanical sources. However, the high content of chalcones and flavonoids ascribed to Z. punctata significantly contributes to the antiallergenic and antioxidant character of these NAPs. This peculiar chemical profile depends on the extremophile condition in which this shrub grows and suggests other studies to characterize such raw materials for oral and topical formulations.

Abstract
Brassica rapa L., an edible and medical vegetable, has been traditionally used in Uyghur folk medicine to treat coughs and asthma in the Xinjiang Uygur Autonomous Region, China. In this study, we prepared an n-butanol subfraction of B. rapa L. (BRBS) and investigated the anti-tumor effect on A549 lung adenocarcinoma cells. The proliferation of A549 cells was significantly inhibited by BRBS treatment in a dose- and time-dependent manner. BRBS significantly induced cell cycle arrest and apoptosis in A549 cells through increased reactive oxygen species (ROS) production and mitochondrial dysfunction characterized by a reduction in mitochondrial membrane potential and the release of cytochrome c, which promoted caspase-3 and poly(ADP-ribose) polymerase processing. Moreover, BRBS significantly suppressed the migration of A549 cells in vitro. These results suggest that BRBS inhibited A549 cell proliferation through increased ROS production and the mitochondria-dependent apoptosis pathway. Consequently, BRBS might be a potential candidate for the treatment of lung cancer.

Abstract
The immune system is complex and pervasive as it functions to prevent or limit infections in the human body. In a healthy organism, the immune system and the redox balance of immune cells maintain homeostasis within the body. The failure to maintain the balance may lead to impaired immune response and either over activity or abnormally low activity of the immune cells resulting in autoimmune or immune deficiency diseases. Compounds containing α,β-unsaturated carbonyl-based moieties are often reactive. The reactivity of these groups is responsible for their diverse pharmacological activities, and the most important and widely studied include the natural compounds curcumin, chalcone, and zerumbone. Numerous studies have revealed the mainly immunosuppressive and anti-inflammatory activities of the aforesaid compounds. This review highlights the specific immunosuppressive effects of these natural α,β-unsaturated carbonyl-based compounds, and their analogs and derivatives on different types of immune cells of the innate (granulocytes, monocytes, macrophages, and dendritic cells) and adaptive (T cells, B cells, and natural killer cells) immune systems. The inhibitory effects of these compounds have been comprehensively studied on neutrophils, monocytes and macrophages but their effects on T cells, B cells, natural killer cells, and dendritic cells have not been well investigated. It is of paramount importance to continue generating experimental data on the mechanisms of action of α,β-unsaturated carbonyl-based compounds on immune cells to provide useful information for ensuing research to discover new immunomodulating agents.

Abstract
The immune system is the defense mechanism in living organisms that protects against the invasion of foreign materials, microorganisms, and pathogens. It involves multiple organs and tissues in human body, such as lymph nodes, spleen, and mucosa-associated lymphoid tissues. However, the execution of immune activities depends on a number of specific cell types, such as B cells, T cells, macrophages, and granulocytes, which provide various immune responses against pathogens. In addition to normal physiological functions, abnormal proliferation, migration, and differentiation of these cells (in response to various chemical stimuli produced by invading pathogens) have been associated with several pathological disorders. The unwanted conditions related to these cells have made them prominent targets in the development of new therapeutic interventions against various pathological implications, such as atherosclerosis and autoimmune diseases. Chalcone derivatives exhibit a broad spectrum of pharmacological activities, such as immunomodulation, as well as anti-inflammatory, anticancer, antiviral, and antimicrobial properties. Many studies have been conducted to determine their inhibitory or stimulatory activities in immune cells, and the findings are of significance to provide a new direction for subsequent research. This review highlights the effects of chalcone derivatives in different types of immune cells.

Abstract
A number of 3-phenylquinolinylchalcone derivatives were synthesized and evaluated in vitro for their antiproliferative activities against three breast cancer cell lines (MCF-7, MDA-MB-231, and SKBR-3), and a non-cancer normal epithelial cell line (H184B5F5/M10). Among them, (E)-3-[3-(4-methoxyphenyl)quinolin-2-yl]-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (7) was active against the growth of MCF-7, MDA-MB-231, and SKBR-3 with IC50 values of 1.05, 0.75, and 0.78 μM respectively without significant cytotoxicity to the normal H184B5F5/M10 cell line and therefore, was selected as a new lead for further mechanism studies. Results indicated that compound 7 inhibited the polymerization of tubulins, induced G2/M cell cycle arrest via modulation of the cyclin B1, cdk1 and CDC25. Compound 7 ultimately induced cell apoptosis by the increase of apoptotic protein Bax and the decrease of anti-apoptotic protein Bcl-2. In addition, PARP was cleaved while caspase-3 and -8 activities were induced after the treatment of compound 7 for 24 h in a concentration-dependent manner. Thus, compound 7 induces cell cycle arrest at G2/M phase via cleavage of PARP, induces caspase-3 and -8 activities and consequently to cause the cell death. Further study on the structure optimization of 7 is ongoing.

Abstract
The cellular effects of eleven compounds including chalcone glycosides isolated from Brassica rapa L. 'hidabeni' and their synthetic derivatives were studied in rat pheochromocytoma PC12 cells. Of the compounds tested, 4'-O-β-D-glucopyranosyl-3',4-dimethoxychalcone (A2) significantly increased the levels of the phosphorylated forms of extracellular signal-regulated kinases 1/2 (ERK 1/2), p38 mitogen-activated protein kinase (p38MAPK), and stress-activated protein kinases/Jun amino-terminal kinases (JNK/SAPK), but it did not affect Akt. Nerve growth factor (NGF), a well-known neurotrophic factor, increased the levels of phosphorylated ERK1/2, JNK/SAPK, and Akt but not p38MAPK, which may mediate marked neurite outgrowth. Signals evoked by A2 shared common characteristics with those induced by NGF; therefore, we evaluated the neuritogenic activity of A2 and found it induced only weak neurite outgrowth. However, this effect was enhanced by pre-treatment with a p38MAPK inhibitor, suggesting that the phosphorylation of p38MAPK down-regulated neurite outgrowth. From the results of this study, it was found that A2 in combination with a p38MAPK inhibitor can induce NGF-like effects. Hence, a combination of chalcone glycosides containing A2 and a p38MAPK inhibitor increases the likelihood that chalcone glycosides could be put to practical use in the form of drugs or alternative medicines to maintain neural health.

Abstract
Recently, some endocannabinoids were reported to show anti-inflammatory and anti-allergic activities. In this respect, various arachidonoyl endocannabinoids were screened for the inhibition of allergic response in IgE-activated RBL-2H3 cells. Among arachidonoyl endocannabinoids with a low cytotoxicity, only NA-5HT remarkably inhibited the release of β-hexosaminidase (IC(50), 13.58 μM), a marker of degranulation, and tumor necrosis factor-α (IC(50), 12.52 μM), a pro-inflammatory cytokine, in IgE-activated RBL-2H3 cells. Additionally, NA-5HT markedly suppressed the formation of prostaglandin D(2) (PGD(2)) with IC(50) value of 1.27 μM and leukotriene B(4) (LTB(4)) with IC(50) value of 1.20 μM, and slightly LTC4. When effect of NA-5HT on early stage of FcεRI cascade was investigated, it significantly inhibited phosphorylation of Syk, but not Lyn. Furthermore, NA-5HT suppressed phosphorylation of PLCγ1/2 and PKCδ, related to degranulation process, as well as phosphorylation of LAT, ERK1/2, p38, JNK, Gab2, PI3K and Akt, implicated in the expression of pro-inflammatory cytokines. Relative to its effect on the late stage, NA-5HT slightly reduced phosphorylation of 5-lipoxygenase (5-LO) and cyclooxygenase-2 (COX-2). Additionally, NA-5HT significantly reduced the level of p40(phox), and partially inhibited the expression of p47(phox) and p67(phox). From these results, it is suggested that NA-5HT expresses anti-allergic action by suppressing the activation of Syk, LAT, p38, JNK, PI3K and Akt, as well as the expression of ERK1/2 and NADPH oxidase subunits. Further, a strong inhibition of PGD(2) or LTB(4) biosynthesis by NA-5HT may be an additional mechanism for its anti-allergic action. Such anti-allergic actions of NA-5HT may contribute to further information about its biological functions.

'hidabeni' and their synthetic derivatives on LPS-induced NO production in microglia. Bioorg Med Chem 2011; 19:5559-68. [PMID: 21856162 DOI: 10.1016/j.bmc.2011.07.036] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2011] [Revised: 07/19/2011] [Accepted: 07/20/2011] [Indexed: 01/17/2023]
Abstract
Activation of microglia induces the production of various inflammatory mediators including nitric oxide (NO), leading to neurodegeneration in many central nervous system diseases. In this study, we examined the effects of chalcone glycosides isolated from Brassica rapa L. 'hidabeni' on lipopolysaccharide (LPS)-induced NO production using rat immortalized microglia HAPI cells. 4'-O-β-D-Glucopyranosyl-3',4-dimethoxychalcone (A2) inhibited LPS-induced inducible NO synthase (iNOS) expression and NO production. However, A2 did not affect nuclear factor-κB and mitogen-activated protein kinase pathways. The signal transduction and activator of transcription 1 (STAT1), which is activated via production of IFN-β by LPS, is an important transcription factor responsible for LPS-induced iNOS expression. A2 suppressed LPS-induced phosphorylation and nuclear translocation of STAT1, although it had no effects on LPS-induced IFN-β expression. These results indicate that the inhibitory effect of A2 is due to the prevention of STAT signaling. Moreover, structure-activity relationship studies on newly synthesized 'hidabeni' chalcone derivatives showed that 4'-O-β-D-glucopyranosyl-3'-methoxychalcone (A11), which has no functional groups in the B-ring, inhibits LPS-induced NO production more potently than A2.
