Abstract
Phenolic acid glycerols (PAGs) are a group of rare phytochemicals found from potato periderm, which show great potential in the food, cosmetic and pharmaceutical industries. In this study, seven PAGs were enzymatically synthesized via transesterification of ethyl phenates (EPs) with glycerol by ultrasonic promotion. The conversions of 88.1–98.5% could be obtained in 1–9 h. Compared with the conventional stirring methods, the catalytic efficiency was significantly increased 11.0–44.0 folds by ultrasound assistance. The lipid peroxidation inhibition activity increased 8.1-fold and 14.4-fold compared to the parent phenolic acids (PAs). Furthermore, caffeoyl glycerol and feruloyl glycerol exhibited excellent antimicrobial activity against Escherichia coli compared to the corresponding PAs with minimum inhibitory concentration (MIC) decreasing 4–16-fold. The PAGs can also absorb a much wider and higher amount of the harmful UV-B rays than the corresponding PAs. The present strategy for facile synthesis of multifunctional PAGs paves the way for the development and application of natural phytochemicals and novel ingredients. A group of rare nature-identical phenolic acid glycerol derivatives was enzymatically prepared and identified, and showed much better antioxidant and antimicrobial activities than the corresponding phenolic acids.![]()

Abstract
Serendipita (=Piriformospora) indica is a fungal endophytic symbiont with the capabilities to enhance plant growth and confer resistance to different stresses. However, the application of this fungus in the field has led to inconsistent results, perhaps due to antagonism with other microbes. Here, we studied the impact of individual bacterial isolates from the endophytic bacterial community on the in vitro growth of S. indica. We further analyzed how combinations of bacteria and S. indica influence plant growth and protection against the phytopathogens Fusarium oxysporum and Rhizoctonia solani. Bacterial strains of the genera Bacillus, Enterobacter and Burkholderia negatively affected S. indica growth on plates, whereas Mycolicibacterium, Rhizobium, Paenibacillus strains and several other bacteria from different taxa stimulated fungal growth. To further explore the potential of bacteria positively interacting with S. indica, four of the most promising strains belonging to the genus Mycolicibacterium were selected for further experiments. Some dual inoculations of S. indica and Mycolicibacterium strains boosted the beneficial effects triggered by S. indica, further enhancing the growth of tomato plants, and alleviating the symptoms caused by the phytopathogens F. oxysporum and R. solani. However, some combinations of S. indica and bacteria were less effective than individual inoculations. By analyzing the genomes of the Mycolicibacterium strains, we revealed that these bacteria encode several genes predicted to be involved in the stimulation of S. indica growth, plant development and tolerance to abiotic and biotic stresses. Particularly, a high number of genes related to vitamin and nitrogen metabolism were detected. Taking into consideration multiple interactions on and inside plants, we showed in this study that some bacterial strains may induce beneficial effects on S. indica and could have an outstanding influence on the plant-fungus symbiosis.

Abstract
Two new glycosylated alkylresorcinols, resorcinosides A (1) and B (2), were isolated from a strain of the fungus Penicillium janthinellum derived from a marine sediment sample collected from Cu Lao Cham Island, Vietnam. The structures of 1 and 2 were established by interpretation of 1D and 2D NMR and high-resolution ESIMS data, and their absolute configurations were confirmed by the coupling constant of the anomeric proton, acid hydrolysis, subsequent HPLC analysis, Mosher's method, and quantum-mechanics-based computational analysis of NMR chemical shifts. The structure elucidation indicated that 1 and 2 are new alkylresorcinols with d-glucose, and 2 has an α-pyrone moiety attached to the aromatic ring. Compound 1 exhibited cytotoxic activity against the NUGC-3 cancer cell line with a GI50 value of 9.3 μM.

Abstract
Uncultivated bacterial symbionts from the candidate genus "Entotheonella" have been shown to produce diverse natural products previously attributed to their sponge hosts. In addition to these known compounds, "Entotheonella" genomes contain rich sets of biosynthetic gene clusters that lack identified natural products. Among these is a small type III polyketide synthase (PKS) cluster, one of only three clusters present in all known "Entotheonella" genomes. This conserved "Entotheonella" PKS (cep) cluster encodes the type III PKS CepA and the putative methyltransferase CepB. Herein, the characterization of CepA as an enzyme involved in phenolic lipid biosynthesis is reported. In vitro analysis showed a specificity for alkyl starter substrates and the production of tri- and tetraketide pyrones and tetraketide resorcinols. The conserved distribution of the cep cluster suggests an important role for the phenolic lipid polyketides produced in "Entotheonella" variants.

Abstract
Covering: up to 2019 Alkylresorcinols are amphiphilic metabolites, well-known for their diverse biological activities, produced by both prokaryotes and eukaryotes. A few classes of alkylresorcinol scaffolds have been reported from the photoautotrophic cyanobacteria, ranging from the relatively simple hierridins to the more intricate cylindrocyclophanes. Recently, it has emerged that cyanobacteria employ two different biosynthetic pathways to produce unique alkylresorcinol scaffolds. However, these convergent pathways intersect by sharing biosynthetic elements which lead to common structural motifs. To obtain a broader view of the biochemical diversity of these compounds in cyanobacteria, we comprehensively cover the isolation, structure, biological activity and biosynthesis of their mono- and dialkylresorcinols. Moreover, we provide an overview of the diversity and distribution of alkylresorcinol-generating biosynthetic gene clusters in this phylum and highlight opportunities for discovery of novel alkylresorcinol scaffolds. Because some of these molecules have inspired notable syntheses, different approaches used to build these molecules in the laboratory are showcased.

Abstract
Substituted hydroxy-benzofurans are easily accessible by treatment of resorcinols and 1,2-diaza-1,3-dienes (DDs) under acidic conditions. The reaction happens through an uncommon Michael reaction between aromatic derivatives as aromatic C(sp2)-H nucleophiles and DDs as acceptors. Also, the behavior of different phenols and 2-naphthol was investigated.

Abstract
Angiogenesis plays an important role in active inflammation and wound healing. Our results showed that silk sericin and 4-hexylresorcinol (4HR) increased vascular endothelial growth factor (VEGF) expression in a dose-dependent manner in RAW264.7 cells. Unlike 4HR, silk sericin increased the expression of hypoxia inducible factor-1α (HIF-1α) and HIF-2α. Pretreatment with an HIF inhibitor decreased the sericin-induced increase in VEGF expression. However, the HIF inhibitor did not affect the 4HR-induced increase in VEGF expression. An inhibitor of matrix metalloproteinase (MMP) declined the 4HR-induced increase in VEGF expression. Silk sericin increased production of reactive oxygen species (ROS), whereas 4HR decreased ROS. M1 markers were increased by silk sericin treatment, and M2 markers were increased by 4HR treatment. VEGF and angiogenin expression were higher in rats treated with a 4HR-incorporated silk mat than in rats treated with a silk mat alone. In conclusion, silk sericin and 4HR increased VEGF expression in RAW264.7 cells via HIF-mediated and MMP-mediated pathways, respectively. Silk sericin exerted like pro-oxidant effects and 4HR exerted anti-oxidant effects. Rats treated with a 4HR-incorporated silk mat showed higher levels of VEGF and angiogenin than those treated with a silk mat alone.

Abstract
The amphyphylic triazoanilines recently synthesized 1-(4-(3-aminophenyl)-1H-1,2,3- triazole-1-yl)-3-(3-pentadecylphenoxy)propan-2-ol (1) and 1-(4-(4-aminophenyl)-1H- 1,2,3-triazole-1-yl)-3-(3-pentadecylphenoxy)propan-2-ol (2), synthesized from cardanol and glycerol, have photophysical properties which allow their use in the development of fluorescent biomarkers with applicability in the biodiesel quality control. Based on this, the present research evaluated the toxic effects of both compounds in different biological models through the investigation of survival and mortality percentages as a measure of acute toxicity on Daphnia similis and Oreochromis niloticus, larvicidal assay against Aedes aegypti, and cytotoxic activity on mammary cells. Results demonstrate that these triazoanilines 1 and 2 have shown low acute toxicity to the biological models investigated in this study up to the following concentrations: 4.0 mg L-1 (D. similis), 4.0 mg L-1 (A. aegypti larvae), 1.0 mg L-1 (O. niloticus), and 1.0 mg mL-1 (mammary cells). This fact suggests the potential for safe use of compounds 1 and 2 as fluorescent markers for the monitoring of biodiesel quality, even in the case of environmental exposure. Besides all of that, the reuse of cardanol and glycerol, both industrial wastes, favors the maintenance of environmental health and is in agreement with the assumptions of green chemistry.

Abstract
Small, single-celled planktonic cyanobacteria are ubiquitous in the world's oceans yet tend not to be perceived as secondary metabolite-rich organisms. Here we report the isolation and structure elucidation of hierridin C, a minor metabolite obtained from the cultured picocyanobacterium Cyanobium sp. LEGE 06113. We describe a simple, straightforward synthetic route to the scarcely produced hierridins that relies on a key regioselective halogenation step. In addition, we show that these compounds originate from a type III PKS pathway and that similar biosynthetic gene clusters are found in a variety of bacterial genomes, most notably those of the globally distributed picocyanobacteria genera Prochlorococcus, Cyanobium and Synechococcus.

Molecules 2019; 24:molecules24040770. [PMID: 30795501 PMCID: PMC6412215 DOI: 10.3390/molecules24040770] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2018] [Revised: 02/18/2019] [Accepted: 02/19/2019] [Indexed: 11/16/2022] Open
Abstract
A rapid and convenient biochemometrics-based analysis of several cereal-derived extracts was used to identify n-alkyl(enyl)resorcinols (AR) as antifungals against Fusarium oxysporum. Total AR content and liquid chromatography/mass spectrometry (LC-MS)-based profiles were recorded for each extract, in addition to their antifungal activity, to help integrate these chemical and biological datasets by orthogonal partial least squares regression. In this study, we developed and used a micro-scale amended medium (MSAM) assay to evaluate the in vitro mycelial growth inhibition at low amounts of extracts. Triticale husk-derived extracts had the highest AR content (662.1 µg olivetol equivalent/g dry extract), exhibiting >79% inhibition at the highest doses (10.0–1.0 µg/µL). Correlation of the chemical and antifungal datasets using supervised metabolite profiling revealed that 5-n-nonadecanylresorcinol, 5-n-heneicosylresorcinol, and 5-n-tricosyl-resorcinol were the most active ARs occurring in cereal products from Colombia. Hence, we propose the biochemometrics-based approach as a useful tool for identifying AR-like antifungals against F. oxysporum.

Abstract
Aedes aegypti and Culex quinquefasciatus are vectors of diseases that constitute public health problems. The discovery of products capable of inhibiting their development which are less harmful to the environment would have a huge impact on vector control. Here, natural cashew nut shell liquid (CNSL), technical CNSL, anacardic acid, cardanol, and cardol were isolated from Anacardium occidentale and evaluated for larvicidal and pupicidal activity against Ae. aegypti and Cx. quinquefasciatus under laboratory and field conditions. The activities of phenol, resorcinol, salicylic acid, and pentadecane, commercial chemicals similar in structure to nut shell derivatives, were also evaluated. All of the fractions extracted from A. occidentale oil exerted larvicidal effects against both mosquito species (LC50 5.4-22.6 mg/L), and two of the aforementioned were effective against pupae (LC50 90.8-109.7 mg/L). Of all the fractions tested, cardol demonstrated the strongest larvicidal and pupicidal effects and presented the most prolonged residual activity against the larvae and pupae of Ae. aegypti and Cx. quinquefasciatus under field conditions. This study suggests that A. occidentale nut shell derivatives are sustainable and promising candidates for the development of novel insecticides to overcome the problem of harmful chemical insecticides.

Bioactivity and Structural Properties of Novel Synthetic Analogues of the Protozoan Toxin Climacostol. Toxins (Basel) 2019; 11:toxins11010042. [PMID: 30650514 PMCID: PMC6356496 DOI: 10.3390/toxins11010042] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2018] [Revised: 01/07/2019] [Accepted: 01/08/2019] [Indexed: 12/31/2022] Open
Abstract
Climacostol (5-[(2Z)-non-2-en-1-yl]benzene-1,3-diol) is a resorcinol produced by the protozoan Climacostomum virens for defence against predators. It exerts a potent antimicrobial activity against bacterial and fungal pathogens, inhibits the growth of several human and rodent tumour cells, and is now available by chemical synthesis. In this study, we chemically synthesized two novel analogues of climacostol, namely, 2-methyl-5 [(2Z)-non-2-en-1-yl]benzene-1,3-diol (AN1) and 5-[(2Z)-non-2-en-1-yl]benzene-1,2,3-triol (AN2), with the aim to increase the activity of the native toxin, evaluating their effects on prokaryotic and free-living protists and on mammalian tumour cells. The results demonstrated that the analogue bearing a methyl group (AN1) in the aromatic ring exhibited appreciably higher toxicity against pathogen microbes and protists than climacostol. On the other hand, the analogue bearing an additional hydroxyl group (AN2) in the aromatic ring revealed its ability to induce programmed cell death in protistan cells. Overall, the data collected demonstrate that the introduction of a methyl or a hydroxyl moiety to the aromatic ring of climacostol can effectively modulate its potency and its mechanism of action.

Abstract
Abstract The propolis produced by stingless bees of the tribe Meliponini is a viscous product that contains the resin collected from buds, leaves and plant exudates, mixed with salivary secretions, wax and soil. The species Scaptotrigona aff. postica (Latreille, 1807), (Hymenoptera, Apidae, Meliponinae) popularly known as “tubi” in Maranhão State, Brazil, does not mix soil to produce its propolis. The propolis from S. postica harvested in Barra do Corda, Maranhão State, is popularly used in the treatment of wounds and respiratory illnesses. The hydroalcoholic extract of this propolis, rich in flavone-6,8-di-C-glycosides (vicenin-2 and schaftoside), pyrrolizidine alkaloids derived from retronecine, catechin and caffeoylquinic acid derivatives exhibited antiviral activity against the herpes simplex and rubella viruses. The aim of this study was to increase knowledge about the chemical composition of the S. postica propolis by analyzing non-polar extracts obtained using hexane and chloroform as the solvents, by GC-EI-MS. A total of 15 constituents were identified comparing their respective mass spectral data with those available in the NIST data bases and those reported in the literature. The main constituents detected were the phenolic lipids, known as cardanols, 3-(4,7-heptadecadienyl) phenol (5), 3-(10-heptadecenyl) phenol (7), 3-heptadecylphenol (9) and 3-pentadecyl phenol or hydrocardanol (13), which predominated in the hexane extract, while the predominant constituents in the chloroform extract were 3-pentadecyl phenol or hydrocardanol (13) and 3-(8-pentadecenyl) phenol (12). The antioxidant, antitumoral, antifeedant, cytotoxic, anticarcinogenic, antiproliferative, antimicrobial, antileishmanial and larvicidal activities of the cardanols have been demonstrated in many studies.

Abstract
Dengue virus causes a global burden that specific chemotherapy has not been established. A previous report suggested that anacardic acid inhibited hepatitis C virus infection. Here, we explored structure activity relationship of anacardic acid, cardanol, and cardol homologues with anti-DENV cellular infectivities. Cardol triene showed the highest therapeutic index at 29.07 with the CC50 and EC50 of 207.30 ± 5.24 and 7.13 ± 0.72 µM, respectively. Moreover, we observed that the more unsaturated the hydrocarbon tail, the higher the CC50s in all head groups. High CC50s were also found in HepG-2, THP-1, and HEK-293 cell lines where cardol triene CC50s were 140.27 ± 8.44, 129.77 ± 12.08, and 92.80 ± 3.93 µM, respectively. Cardol triene expressed pan-dengue inhibition with the EC50s of 5.35 to 8.89 µM and kl loops of dengue envelope proteins were major targets. The strong binding energy at T48, E49, A50, P53, K128, V130, L135, M196, L198, Q200, W206, L207, I270, and L277 prevented cellular pH-dependent fusion. Zika virus kl loops were aligned in the closed position preventing cardol triene to bind and inhibit fusion and infectivity. This study showed for the first time that cardol triene had a potential for further development as anti-dengue inhibitors.

Abstract
AIM The effect of anacardic acid impregnation on catheter surfaces for the prevention of Staphylococcus aureus attachments and biofilm formations were evaluated. METHODS AND RESULTS Silicon catheter tubes were impregnated using different concentrations of anacardic acids (0·002-0·25%). Anacardic acids are antibacterial phenolic lipids from cashew nut (Anacardium occidentale) shell oil. Anacardic acid-impregnated silicon catheters revealed no significant haemolytic activity and were cytocompatible against fibroblast cell line (L929). Sustained release of anacardic acids was observed for 4 days. Anacardic acid-impregnated silicon catheters efficiently inhibited S. aureus colonization and the biofilm formation on its surface. The in vivo antibiofilm activity of anacardic acid-impregnated catheters was tested in an intraperitoneal catheter-associated medaka fish infection model. Significant reduction in S. aureus colonization on anacardic acid-impregnated catheter tubes was observed. CONCLUSIONS Our data suggest that anacardic acid-impregnated silicon catheters may help in preventing catheter-related staphylococcal infections. SIGNIFICANCE AND IMPACT OF THE STUDY This study opens new directions for designing antimicrobial phytochemical-coated surfaces with ideal antibiofilm properties and could be of great interest for biomedical research scientists.

Abstract
The inhibitory activity of xanthine oxidase (XO) is a combination of uric acid formation inhibition and superoxide anion (O2-) generation suppression. The inhibition of uric acid formation by XO is useful for the screening of natural compounds that prevent gout, while the suppression of O2- generation is useful for treating oxidative stress. Many edible plants contain abundant phenolic compounds and alk(en)yl phenols, and some of these compounds display XO inhibitory activity. This review focuses on XO inhibitory activity since this activity is used to characterize natural products. Recently, it was demonstrated that the inhibitory activity could be characterized using assays for XO inhibition, the suppression of O2- generation, DPPH radical scavenging and O2- radical scavenging. The inhibitory activity was divided three reaction types. The first is XO inhibition, the second O2- generation suppression by modification of enzyme molecules and the third two forms of O2- scavenging. It was demonstrated that these three activities are related to both the hydroxy group arrangement in the phenol portion and the alk(en)yl chains. This characterization is useful for pursuing XO inhibitors and antioxidants in natural compounds.

Abstract
BACKGROUND Anacardium occidentale L phenolic lipid (LDT11) is used in traditional medicine as anti-inflammatory, astringent, antidiarrheal, anti-asthmatic and depurative. Phenolic derivatives, such as anacardic acid, extracted from cashew nut shell liquid (CNSL) have demonstrated biological and pharmacological properties, and its profile makes it a candidate for the development of new anti-inflammatory agents. The objective of the present study was to evaluate the anti-inflammatory profile of a derivative, synthesized from LDT11, on an in vitro cellular model. METHODS Organic synthesis of the phenolic derivative of CNSL that results in the hemi-synthetic compound LDT11. The cytotoxicity of the planned compound, LDT11, was analyzed in murine macrophages cell line, RAW264.7. The cells were previously treated with LDT11, and then, the inflammation was stimulated with lipopolysaccharide (LPS), in intervals of 6 h and 24 h. The analysis of the gene expression of inflammatory markers (TNFα, iNOS, COX-2, NF-κB, IL-1β and IL-6), nitric oxide (NO) dosage, and cytokine IL-6 were realized. RESULTS The results showed that the phenolic derivative, LDT11, influenced the modulatory gene expression. The relative gene transcripts quantification demonstrated that the LDT11 disclosed an immunoprotective effect against inflammation by decreasing genes expression when compared with cells stimulated with LPS in the control group. The NO and IL-6 dosages confirmed the results found in gene expression. DISCUSSION The present study evaluated the immunoprotective effect of LDT11. In addition to a significant reduction in the expression of inflammatory genes, LDT11 also had a faster and superior anti-inflammatory action than the commercial products, and its response was already evident in the test carried out six hours after the treatment of the cells. CONCLUSION This study demonstrated LDT11 is potentially valuable as a rapid immunoprotective anti-inflammatory agent. Treatment with LDT11 decreased the gene expression of inflammatory markers, and the NO, and IL-6 production. When compared to commercial drugs, LDT11 showed a superior anti-inflammatory action.

Erşan S, Güçlü Üstündağ Ö, Carle R, Schweiggert RM. Subcritical water extraction of phenolic and antioxidant constituents from pistachio (Pistacia vera L.) hulls. Food Chem 2018; 253:46-54. [PMID: 29502842 DOI: 10.1016/j.foodchem.2018.01.116] [Citation(s) in RCA: 51] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Revised: 12/13/2017] [Accepted: 01/16/2018] [Indexed: 12/21/2022]
Abstract
Pistachio hulls, important by-products of pistachio processing, were extracted using an environmentally friendly process with subcritical water (SCW) at a pressure of 6.9 MPa in the range of 110 and 190 °C, and a flow rate of 4 ml/min. Detailed HPLC-DAD-ESI/MSn analyses allowed the identification of 49 phenolic compounds in the SCW extracts. Total gallotannin yields up to 33 g/kg were reached at 150-170 °C, where gallic acid (22.2 g/kg) and penta-O-galloyl-β-d-glucose (9.77 g/kg) levels were 13.2- and 10.6-fold higher than those in the aqueous methanol extracts. Flavonols were also effectively extracted at 110-150 °C (4.37-5.65 g/kg), while anacardic acid recovery was poor (1.13-2.77 g/kg). Accordingly, high amounts of anacardic acids (up to 50.7 g/kg) were retained in the extraction residue, revealing that SCW extraction allowed selective extraction of gallotannins and flavonols. Antioxidant capacities ranged from 0.68 to 1.20 mmol Trolox equivalents (TE)/g for SCW extracts increasing with temperature up 190 °C.

Abstract
Profound screening and evaluation methods for biocide-releasing polymer films are crucial for predicting applicability and therapeutic outcome of these drug delivery systems. For this purpose, we developed an agar overlay assay embedding biopolymer composite films in a seeded microbial lawn. By combining this approach with model-dependent analysis for agar diffusion, antimicrobial potency of the entrapped drug can be calculated in terms of minimum inhibitory concentrations (MICs). Thus, the topical antiseptic 4-hexylresorcinol (4-HR) was incorporated into poly(lactic-co-glycolic acid) (PLGA) films at different loadings up to 3.7 mg/cm² surface area through a solvent casting technique. The antimicrobial activity of 4-HR released from these composite films was assessed against a panel of Gram-negative and Gram-positive bacteria, yeasts and filamentous fungi by the proposed assay. All the microbial strains tested were susceptible to PLGA-4-HR films with MIC values down to 0.4% (w/w). The presented approach serves as a reliable method in screening and quantifying the antimicrobial activity of polymer composite films. Moreover, 4-HR-loaded PLGA films are a promising biomaterial that may find future application in the biomedical and packaging sector.

Genome sequence and comparative analysis of Jiangella alba YIM 61503 T isolated from a medicinal plant Maytenus austroyunnanensis. Antonie van Leeuwenhoek 2017; 111:667-678.

Abstract
A draft genome sequence of Jiangella alba YIM 61503T revealed a genome size of 7,664,864 bp arranged in 33 scaffolds. The genome was predicted to contain 7196 predicted genes, including 51 coding for RNA. Phylogenetic and comparative analyses of the draft genome of J. alba YIM 61503T with the available genomes of other Jiangella species suggested a proximal similarity between strains J. alba YIM 61503T and J. muralis DSM 45357T, while indicating a high divergence between J. gansuensis YIM 002T and other Jiangella species. The genome of J. alba YIM 61503T also revealed genes involved in indole-3-acetic acid biosynthesis and an alkylresorcinols gene cluster. Further, detection of phosphotransferase genes in the genome of all Jiangella species indicated that they can uptake and phosphorylate sugars. The presences of TreX-Z, TreS and OtsA-OtsB genes in some of the Jiangella strains also indicated a possible mechanism for their tolerance of high salinity. Besides providing new insights into its genetic features, our results suggested that J. alba YIM 61503T could be a potential strain for further genome mining studies. The release of this genome may, therefore, provide a better prospect for understanding "evolutionary taxonomy" about this genus in future.

Abstract
Chemotherapy is one of the major approaches for the treatment of cancer. Therefore,
the development of new chemotherapy drugs is an important aspect of medicinal
chemistry. Chemotherapeutic agents include isocoumarins, which are privileged
structures with potential antitumoral activity. Herein, a new 3-substituted
isocoumarin was synthesized from 2-iodo-3,5-dimethoxy-benzoic acid and oct-1-yne in a
cross-coupling Sonogashira reaction followed by a copper iodide-catalyzed
intramolecular cyclization as key step using MeOH/Et3N as the solvent
system. The present study also evaluated the leukometry, phagocytic activity,
genotoxic potential and cell death induction of three different doses (5 mg/kg, 10
mg/kg and 20 mg/kg) of this newly synthesized isocoumarin, alone and in combination
with the commercial chemotherapeutic agents cyclophosphamide (100 mg/kg) and
cisplatin (6 mg/kg) in male Swiss mice. The results suggest that the isocoumarin has
genotoxicity and causes cell death. Noteworthy, this new compound can increase
splenic phagocytosis and lymphocyte frequency, which are related to immunomodulatory
activity. When combined with either cyclophosphamide or cisplatin, chemopreventive
activity led to a reduction in the effects of both chemotherapeutic drugs. Thus, the
new isocoumarin is not a candidate for chemotherapeutic adjuvant in treatments using
cyclophosphamide or cisplatin. Nevertheless, the compound itself is an important
prototype for the development of new antitumor drugs.

Abstract
Fatty acids and lipids, which are major and essential constituents of all plant cells, not only provide structural integrity and energy for various metabolic processes but can also function as signal transduction mediators. Lipids and fatty acids can act as both intracellular and extracellular signals. In addition, cyclic and acyclic products generated during fatty acid metabolism can also function as important chemical signals. This review summarizes the biosynthesis of fatty acids and lipids and their involvement in pathogen defense.

Abstract
Cashew nuts are important both nutritionally and industrially, but can also cause food allergies in some individuals. The present study aimed to assess the effect(s) of industrial processing on anacardic acids and allergens present in cashew nuts. Sample analyses were performed using liquid chromatography coupled with mass spectrometry, SDS-PAGE and immunoassay. The anacardic acid concentration ranged from 6.2 to 82.6mg/g during processing, and this variation was attributed to cashew nut shell liquid incorporation during storage and humidification. Dehydrated and selected samples did not significantly differ in anacardic acid content, having values similar to the raw sample. SDS-PAGE and immunoassay analysis with rabbit polyclonal sera and human IgE indicated only minor differences in protein solubility and antibody binding following processing steps. The findings indicate that appreciable amounts of anacardic acid remain in processed nuts, and that changes to cashew allergens during industrial processing may only mildly affect antibody recognition.

Abstract
Mangifera zeylanica is a plant endemic to Sri Lanka and its bark has been used in traditional medicine to treat some cancers. This study was aimed to isolate potentially cytotoxic compound/s from the hexane extract of the bark of M. zeylanica by bio-activity guided fractionation. The structure of the isolated compound (1) was elucidated using 1H, 13C NMR and mass spectrometric techniques. Compound 1 was identified as a new resorcinolic lipid (5-((8Z, 11Z, 14Z)-hexatriaconta-8, 11, 14-trienyl) benzene-1,3-diol). Apoptotic potential of the isolated compound was determined only in MCF-7 (estrogen receptor positive) breast cancer cells to which it was more cytotoxic than to normal mammary epithelial cells. Oxidative stress markers [reactive oxygen species (ROS), glutathione levels (GSH) and glutathione-S-transferase (GSH)] were also determined in MCF-7 cells treated with compound 1. Treatment with compound 1 led to an increase in caspase 7 activity, morphological features of apoptosis and DNA fragmentation in MCF-7 cells. Furthermore, it also led to an increase in ROS and GST levels while depleting GSH levels. Results of this study suggest that isolated new resorcinolic lipid can induce apoptosis in MCF-7 cells, possibly via oxidative stress mechanism.

Abstract
Mango industry processing generates high quantities of mango by-products such as peels and seeds (35%-60% of the fruit). Indeed, it is known that mango and its by-products contain different families of bioactive compounds that possess several health benefits. Thus, the aim of this study has been the determination of different families of phenolic derivatives (free and bound phenolic compounds and alk(en)ylresorcinols (ARs)) in mango edible part and its by-products (peel, seed and seed husk) from three different cultivars. This is the first study that evaluates the phenolic compounds and ARs in the four fractions of mango of three different cultivars. Special attention has been paid to the determination of anthocyanins and ARs, because these families of compounds had not been studied in depth in mango. In fact, petunidin rutinoside-(p-coumaric acid) gallate was found in mango pulp, peel, seed and seed husk of the three cultivars and, it had never been described in mango before. It is also important to highlight that this is the first time that the identification and quantification of ARs have been performed in mango seed and seed husk; besides, four and five out of eleven alk(en)ylresorcinols detected in peel and pulp, respectively, were identified for the first time in these mango fractions. Furthermore, antioxidant activity was measured by ABTS and FRAP assays. Seed free and bound phenolic extracts showed the highest antioxidant capacity.

Abstract
The synthesis of five novel methyl 10-undecenoate-based lipoconjugates of phenolic acids from undecenoic acid was carried out. Undecenoic acid was methylated to methyl 10-undecenoate which was subjected to a thiol–ene reaction with cysteamine hydrochloride. Further amidation of the amine was carried out with different phenolic acids such as caffeic, ferulic, sinapic, coumaric and cinnamic acid. All synthesized compounds were fully characterized and their structures were confirmed by spectral data. The anti-oxidant activity of the synthesized lipoconjugates of phenolic acids was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and also by the inhibition of linoleic acid oxidation in micellar medium by differential scanning calorimetry (DSC). The prepared compounds were also screened for their cytotoxic activity against five cell lines. It was observed that the lipoconjugates of caffeic acid, sinapic acid, ferulic acid, and coumaric acid displayed anticancer and anti-oxidant properties. The anticancer properties of these derivatives have been assessed by their IC50 inhibitory values in the proliferation of MDA-MB231, SKOV3, MCF7, DU 145 and HepG2 cancer cell lines.

Food Chem 2016; 221:664-672. [PMID: 27979256 DOI: 10.1016/j.foodchem.2016.11.121] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Revised: 11/19/2016] [Accepted: 11/22/2016] [Indexed: 11/26/2022]
Abstract
Novel phenoylated phosphatidylcholines were synthesized from 1,2-dipalmitoyl phosphatidylcholine/egg 1,2-diacyl phosphatidylcholine and phenolic acids such as ferulic, sinapic, vanillic and syringic acids. The structures of phenoylated phosphatidylcholines were confirmed by spectral analysis. 2-acyl-1-lyso phosphatidylcholine was synthesized from phosphatidylcholine via regioselective enzymatic hydrolysis and was reacted with hydroxyl protected phenolic acids to produce corresponding phenoylated phosphatidylcholines in 48-56% yields. Deprotection of protected phenoylated phosphatidylcholines resulted in phenoylated phosphatidylcholines in 87-94% yields. The prepared compounds were evaluated for their preliminary in vitro antimicrobial and antioxidant activities. Among the active derivatives, compound 1-(4-hydroxy-3,5-dimethoxy) cinnamoyl-2-acyl-sn-glycero-3-phosphocholine exhibited excellent antioxidant activity with EC50 value of 16.43μg/mL. Compounds 1-(4-hydroxy-3-methoxy) cinnamoyl-2-acyl-sn-glycero-3-phosphocholine and 1-(4-hydroxy-3,5-dimethoxy) cinnamoyl-2-palmitoyl-sn-glycero-3-phosphocholine exhibited good antioxidant activity with EC50 values of 36.05 and 33.35μg/mL respectively. Compound 1-(4-hydroxy-3-methoxy) cinnamoyl-2-palmitoyl-sn-glycero-3-phosphocholine exhibited good antibacterial activity against Klebsiella planticola with MIC of 15.6μg/mL and compound 1-(4-hydroxy-3-methoxy) benzoyl-2-acyl-sn-glycero-3-phosphocholine exhibited good antifungal activity against Candida albicans with MIC of 15.6μg/mL.

Antidermatophytic Action of Resorcinol Derivatives: Ultrastructural Evidence of the Activity of Phenylethyl Resorcinol against Microsporum gypseum. Molecules 2016; 21:molecules21101306. [PMID: 27706019 PMCID: PMC6274034 DOI: 10.3390/molecules21101306] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 09/25/2016] [Accepted: 09/27/2016] [Indexed: 11/17/2022] Open
Abstract
In this work, we evaluated the antidermatophytic activities of three resorcinol derivatives that have a history of use in dermo-cosmetic applications to discover molecules with multiple dermatological activities (i.e., multi-target drugs), thereby reducing the cost and time necessary for new drug development. The antidermatophytic activities of the three skin lighteners were evaluated relative to the known antifungal drug fluconazole on nine dermatophytes responsible for the most common dermatomycoses: Microsporum gypseum, Microsporum canis, Trichophyton violaceum, Arthroderma cajetani, Trichophyton mentagrophytes, Epidermophyton floccosum, Nannizzia gypsea, Trichophyton rubrum and Trichophyton tonsurans. Among the three tested resorcinols, only two showed promising properties, with the ability to inhibit the growth of all tested dermatophytes; additionally, the IC50 values of these two resorcinols against the nine dermatophytes confirmed their good antifungal activity, particularly for phenylethyl resorcinol against M. gypseum. Ultrastructural alterations exhibited by the fungus were observed using scanning electron microscopy and transmission electron microscopy and reflected a dose-dependent response to treatment with the activation of defence and self-preservation strategies.

Abstract
BACKGROUND Previous studies on Labisia pumila var. alata (LPva) have showed that it could inhibit low-density lipoprotein (LDL) oxidation and provide protection on myocardial infarction in rats. HYPOTHESIS/PURPOSE We hypothesized that LPva extracts can modulate the lipid profiles and serum antioxidant status of hypercholesterolemic rats. In the present study, we investigated the effects of aqueous and 80% ethanol extracts of LPva on atherogenic and serum antioxidant parameters as well as changes in abdominal aorta of high-cholesterol diet rats. METHODS The major components of the extracts, gallic acid, flavonoids and alkyl resorcinols were analyzed by using a validated reversed phase HPLC method. The rats were induced to hypercholesterolemic status with daily intake of 2% cholesterol for a duration of 8 weeks. Three different doses (100, 200 and 400mg/kg) of the extracts were administered daily on the 4th week onwards. The rats were then sacrificed and the blood was collected via abdominal aorta and serum was separated by centrifugation for biochemical analysis. Part of the aorta tissues were excised immediately for histopathological examination. RESULTS The serum of LPva treated rats showed significant reduction in serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) levels and the abdominal aorta showed a significant decrease of atheroma lesions in treated rats. Serum lipid profiles of treated rats showed a decrease in total cholesterol, total triglycerides and low-density lipoprotein (LDL) levels as compared to control group. The atherogenic indices in treated rats were significantly improved along with an increasing level of serum high-density lipoprotein (HDL). The extracts also exhibited significant increase of antioxidant enzymes and decrease of MDA as a product of lipid peroxidation. CONCLUSION LPva extracts can reduce the risk of dyslipidemia by improving the serum lipid profiles and modulating serum antioxidants.

Abstract
Cardanol is an effective antioxidant and is a compound with antimutagenic and
antitumoral activity. Here, we evaluated the genotoxic and mutagenic potential of
saturated side chain cardanol and its effects in combination with cyclophosphamide in
preventing DNA damage, apoptosis, and immunomodulation. Swiss mice were treated with
cardanol (2.5, 5 and 10 mg/kg) alone or in combination with cyclophosphamide (100
mg/kg). The results showed that cardanol is an effective chemopreventive compound,
with damage reduction percentages that ranged from 18.9 to 31.76% in the comet assay
and from 45 to 97% in the micronucleus assay. Moreover, cardanol has the ability to
reduce the frequency of apoptosis induced by cyclophosphamide. The compound did not
show immunomodulatory activity. A final interpretation of the data showed that,
despite its chemoprotective capacity, cardanol has a tendency to induce DNA damage.
Hence, caution is needed if this compound is used as a chemopreventive agent. Also,
this compound is likely not suitable as an adjuvant in chemotherapy treatments that
use cyclophosphamide.

Abstract
Proteins of the Bcl-2 family are key targets in anticancer drug discovery. Disrupting the interaction between anti- and pro-apoptotic members of this protein family was the approach chosen in this study to restore apoptosis. Thus, a biological screening on the modulation of the Bcl-xL/Bak and Mcl-1/Bid interactions permitted the selection of Knema hookeriana for further phytochemical investigations. The ethyl acetate extract from the stem bark led to the isolation of six new compounds, three acetophenone derivatives (1-3) and three anacardic acid derivatives (4-6), along with four known anacardic acids (7-10) and two cardanols (11, 12). Their structures were elucidated by 1D and 2D NMR analysis in combination with HRMS experiments. The ability of these compounds to antagonize Bcl-xL/Bak and Mcl-1/Bid association was determined, using a protein-protein interaction assay, but only anacardic acid derivatives (4-10) exhibited significant binding properties, with Ki values ranging from 0.2 to 18 μM. Protein-ligand NMR experiments further revealed that anacardic acid 9, the most active compound, does not interact with the anti-apoptotic proteins Bcl-xL and Mcl-1 but instead interacts with pro-apoptotic protein Bid.

Abstract
The polar paradox states that polar antioxidants are more active in bulk lipids than their nonpolar counterparts, whereas nonpolar antioxidants are more effective in oil-in-water emulsion than their polar homologs. However, recent results, showing that not all antioxidants behave in a manner proposed by this hypothesis in oil and emulsion, lead us to revisit the polar paradox and to put forward new concepts, hypotheses, and theories. In bulk oil, new evidences have been brought to demonstrate that the crucial site of oxidation is not the air-oil interface, as postulated by the polar paradox, but association colloids formed with traces of water and surface active molecules such as phospholipids. The role of these association colloids on lipid oxidation and its inhibition by antioxidant is also addressed as well as the complex influence of the hydrophobicity on the ability of antioxidants to protect lipids from oxidation. In oil-in water emulsion, we have covered the recently discovered non linear (or cut-off) influence of the hydrophobicity on antioxidant capacity. For the first time, different mechanisms of action are formulated in details to try to account for this nonlinear effect. As suggested by the great amount of biological studies showing a cut-off effect, this phenomenon could be widespread in dispersed lipid systems including emulsions and liposomes as well as in living systems such as cultured cells. Works on the cut-off effect paves the way for the determination of the critical chain length which corresponds to the threshold beyond which antioxidant capacity suddenly collapses. The systematic search for this new physico-chemical parameter will allow designing novel phenolipids and other amphiphilic antioxidants in a rational fashion. Finally, in both bulk oils and emulsions, we feel that it is now time for a paradigm shift from the polar paradox to the next theories.

Abstract
Quercus cortex (Oak bark) has been used in European folk medicine since medieval times for treatment of diarrhea, stomatitis, pharyngitis and skin inflammations. Its antimicrobial activity is a well-known therapeutic property of oak bark, and its novel anti-quorum sensing (QS) ability has also been described recently. In this study, we examined the bioactive compounds of Quercus cortex extract and compared their direct antibacterial and regulatory anti-QS effects against Chromobacterium violaceum CV026 in a biotest. Evaluation of the original Quercus cortex extract showed weak antibacterial and prominent anti-QS activities that were retained and completely restored when the samples were dried and re-hydrated. The one-step liquid chromatography result indicated that the anti-QS activity might be determined by hydrophobic compounds; however, the subsequent reverse phase high performance liquid chromatography led to dissipation and loss of the activity. The gas chromatography–mass spectrometry gave excellent resolution between a majority of the compounds. Based on this result, 10 of the 35 identified small molecules were selected for further screening. The subsequent investigation indicated several compounds determined both the antibacterial and anti-QS activities of the Quercus cortex extract. Direct antibacterial activity was shown for 1,2,3-benzenetriol and 4-propyl-1,3-benzenediol, while sub-inhibitory concentrations of these compounds led to anti-QS effects. Five compounds: 4-(3-hydroxy-1-propenyl)-2-methoxy-phenol; 3,4,5-trimethoxyphenol; 4-hydroxy-3-methoxybenzaldehyde; 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one and 2H-1-benzopyran-2-one were characterized as QS inhibitors independent of any effect on bacterial growth. Biologically relevant concentrations of each single component showed weak activity only while reconstruction of the small molecule composition derived from the Quercus cortex extract provided comparable complementary activity against C. violaceum CV026 in the biotest as the crude extract.

Abstract
The antioxidant activities of five alkylresorcinol (AR) homologs with alkyl chains of 1, 3, 5 6 and 12 carbon atoms were studied using molecular and cellular assays for superoxide anions (O2.-). The effect of ARs as superoxide anion scavengers was assessed using the photochemical reaction of spontaneous photo-reduced flavin re-oxidation. In this system, ARs reaction with O2.- produced dye derivatives, as C6- and C12-AR prevented the O2.--induced conversion of nitroblue tetrazolium into formazan in AR-containing mixtures. The influence of ARs on soxS gene expression and bacterial cell viability was studied with the luminescent Escherichia coli K12 MG1655 psoxS'::luxCDABE-AmpR strain, showing low basal light emission. This increased significantly during paraquatinduced oxidative stress as a consequence of the simultaneous transcription of soxS-gene and lux-gene fusion. ARs with alkyl chains containing 5-12 carbon atoms at concentrations of 0.1-1.0 μM weakly induced soxS-gene expression, whereas 1-10 mM repressed it. This respectively increased or decreased the bacterial cell resistance to O2.- -related oxidative stress. AR derivatives lost their protective activity from reactions with superoxide anions, which required increased soxS gene expression for cell viability. These results show the dual nature of ARs, which possess direct antioxidant properties and the ability to indirectly regulate the activity of cellular antioxidative defense mechanisms.
