AB  - In the previous study fifteen jatrophane diterpenes were isolated from the Euphorbia nicaeensis latex. Fourteen of them have been shown to be potent P-glycoprotein (P-gp) inhibitor in two MDR cancer cells (NCI-H460/R and DLD1-TxR). The aim of this study was to determine whether and which jatro­phane diterpenes can be isolated from the root of the plant, and then to examine their inhibition power on P-glycoprotein of selected cancer cell lines (NCI-H460, DLD1, U87, NCI-H460/R, DLD1-TxR and U87-TxR). Two previously undes­cribed jatrophane diterpenes were isolated from the root of E. nicaeensis col­lected in Deliblato Sand (Serbia). The structures of the isolated compounds were determined using 1D and 2D NMR, as well as HRESIMS data. The results obtained by MTT assay showed different antitumor potential of these two jatrophanes. Compound 1 inhibited cell growth of non-small cell lung car­cinoma cell lines NCI-H460 and NCI-H460/R, as well as glioblastoma cell lines U87 and U87-TxR, while jatrophane 2 was almost completely inactive in the suppression of cancer cell growth in a given range of concentrations. The obtained results also showed that the isolated compounds have an inhibitory effect on P-glycoprotein, as well as that their inhibitory potential is similar.
AB  - У претходном истраживању, петнаест дитерпена јатрофанског типа изоловано је из латекса Euphorbia nicaeensis. Њих четрнаест показала су се као снажни инхибитори P-гликопротеина (P-gp) у две MDR ћелијске линије рака (NCI-H460/R и DLD1-TxR). Циљ ове студије био је да се утврди да ли је и које јатрофанске дитерпене могуће изо- ловати из корена биљке, а затим испитивање њихове инхибиторне моћи на P-гликопро- теину одабраних ћелијских линија рака (NCI-H460, DLD1, U87, NCI-H460/R, DLD1-TxR и U87-TxR). Два претходно непозната јатрофана изолованa су из корена E. nicaeensis прикупљеног у Делиблатској пешчари. Структуре изолованих једињења одређене су применом 1D и 2D NMR метода, као и HRESIMS експеримента. Резултати добијени МТТ тестом показали су различит антиканцерогени потенцијал ова два јатрофана. Једињење 1 је инхибирало раст ћелија ћелијских линија неситноћелијског карцинома плућа NCI-H460 и NCI-H460/R, као и ћелијских линија глиобластома U87 и U87-TxR, док је јатрофан 2 био готово потпуно неефикасан у сузбијању растa ћелија карцинома у датом концентрационом опсегу. Добијени резултати су такође показали да 1 и 2 имају инхибиторно дејство на P-гликопротеин, као и да је њихов инхибиторни потенцијал сличан.

AB  - This study aimed to estimate the potential of the selected berry (strawberry) and drupe (apricot, plum and sweet cherry) fruits as the substrates for the production of new fruit wines enriched with phenolic compounds. Sweet cherry wine (cultivar Burlat) stood out both for the profound content of phenolics (followed by their chemical profile) and potent anti-DPPH radical activity. The same fruit wine samples exhibited high redox potentials, slightly lower than strawberry and plum wine samples. Therefore, sweet cherry cultivar Burlat may be well recommended for development of novel fruit-based products endowed with naturally occurring phenolics. In any case, the remaining four cultivars are also worth further research efforts, particularly apricot cultivar Keckemetska ruza, which is one of the representatives of greatly underestimated fruit type thus far as a substrate for the production of the relevant fruit wines.

AB  - The detection of illegal drugs in various samples has been among the most fascinating objects for the practicing analytical chemist involved in forensic analysis. For centuries (until the end of the nineteenth century), drugs were almost entirely of natural origin, mostly herbal, and in some cases slightly chemically modified (e.g., through acetylation of morphine to heroin). By the development of synthetic organic chemistry (commencing at the beginning of the twentieth century), quite a few synthetic drugs designed to mimic the pharmacological effects of drugs originating from natural sources have been designed (e.g., cannabimimetic indazole derivatives or amphetamines, etc.). Detection of such synthetic drugs, named “designer drugs,” due to a large number of new substances continuously emerging on the market, is crucial. The efficacy of this analysis has become a tremendous challenge in the analytical forensic field. A development of fast identification and structural characterization is greatly facilitated by the advent of modern spectroscopic techniques, namely nuclear magnetic resonance spectroscopy (NMR) and modern mass spectrometry (MS) as well as separation techniques, such as gas and liquid chromatography (GC and LC). Nowadays, rapid strategies for chemical characterizations of illicit drugs are available.

AB  - New aurone epoxide, 2,10-oxy-10-methoxysulfuretin (14), and new auronolignan (15), named cotinignan A, were isolated by silica gel column and semipreparative HPLC chromatography from the methylene chloride/methanol extract of Cotinus coggygria Scop. heartwood. In addition, thirteen known secondary metabolites namely sulfuretin, 2,3-trans-fustin, fisetin, butin, butein, taxifolin, eriodictyol, 3',5,5',7–tetrahydroxyflavanone, 3',4',7-trihydroxyflavone, 3-O-methyl-2,3-trans-fustin, 3-O-galloyl-2,3-trans-fustin, β-resorcylic acid and 3-O-β-sitosterol glucoside were isolated as well. Their structures were elucidated by 1D and 2D NMR, HR-ESI-MS, IR and UV. Ten out of eleven isolated flavonoids possess 7, 3' and 4' hydroxy groups. These structural features could be considered as chemotaxonomic characteristic of flavonoids from C. coggygria. Cotinignan A (15) represents new subclass of secondary metabolites - auronolignans.

abstract = "New aurone epoxide, 2,10-oxy-10-methoxysulfuretin (14), and new auronolignan (15), named cotinignan A, were isolated by silica gel column and semipreparative HPLC chromatography from the methylene chloride/methanol extract of Cotinus coggygria Scop. heartwood. In addition, thirteen known secondary metabolites namely sulfuretin, 2,3-trans-fustin, fisetin, butin, butein, taxifolin, eriodictyol, 3',5,5',7–tetrahydroxyflavanone, 3',4',7-trihydroxyflavone, 3-O-methyl-2,3-trans-fustin, 3-O-galloyl-2,3-trans-fustin, β-resorcylic acid and 3-O-β-sitosterol glucoside were isolated as well. Their structures were elucidated by 1D and 2D NMR, HR-ESI-MS, IR and UV. Ten out of eleven isolated flavonoids possess 7, 3' and 4' hydroxy groups. These structural features could be considered as chemotaxonomic characteristic of flavonoids from C. coggygria. Cotinignan A (15) represents new subclass of secondary metabolites - auronolignans.

AB  - A number of potentially useful compounds with various biological activities can be obtained from plant metabolites by microorganisms. In present research, essential oil of Calamintha glandulosa was subjected to the biotransformation process by mycromicete Aspergillus niger. GC/MS analyses of the original and biotransformed essential oil have revealed six(1-6) biotransformed compounds from one of the main component-limonene and one biotransformed product (7) originating from the less abundant component-thymol. Piperitone epoxide and piperitenone epoxide, the most abundant components of the original oil, were not biotransformed but gave three artefacts (A1, A2, B1) due to the acidic conditions formed in A. niger medium. Compounds 5, 6 as well as 7 have not been previously found as a biotransformation products of limonene (5 and 6) and thymol (7), respectively. New products (5, 6, and 7) together with the artefacts, were isolated by silica gel column chromatography followed by preparative silica gel thin layer chromatography, and their structures were established by a combination of 1D and 2D NMR spectra and GC/MS data. Biotransformation has one more confirmed as useful method, complementary to synthesis, for obtaining different type of molecules.

AB  - Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus type propolis composition with the altitude of its collection, NMR, IR, and DV spec-troscopy followed by OPLS was conducted. The botanical origin of propolis was established by comparing propolis spectral data to those of buds of various Populus species. An O2PLS method was utilized to integrate two blocks of data. According to OPLS and O2PLS, the major compounds in propolis samples, collected from temperate continental climate above 500 m, were phenolic glycerides originating from P. tremula buds. Flavonoids were predominant in propolis samples collected below 400 m, originating from P. nigra and P.x euramericana buds. Samples collected at 400-500 m were of mixed origin, with variable amounts of all detected metabolites.

AB  - Cave animals live under highly constant ecological conditions and in permanent darkness, and many evolutionary adaptations of cave-dwellers have been triggered by their specific environment. A similar "cave effect" leading to pronounced chemical interactions under such conditions may be assumed, but the chemoecology of troglobionts is mostly unknown. We investigated the defensive chemistry of a largely cave-dwelling julid group, the controversial tribe "Typhloiulini", and we included some cave-dwelling and some endogean representatives. While chemical defense in juliform diplopods is known to be highly uniform, and mainly based on methyl- and methoxy-substituted benzoquinones, the defensive secretions of typhloiulines contained ethyl-benzoquinones and related compounds. Interestingly, ethyl-benzoquinones were found in some, but not all cave-dwelling typhloiulines, and some non-cave dwellers also contained these compounds. On the other hand, ethyl-benzoquinones were not detected in troglobiont nor in endogean typhloiuline outgroups. In order to explain the taxonomic pattern of ethyl-benzoquinone occurrence, and to unravel whether a cave-effect triggered ethyl-benzoquinone evolution, we classed the "Typhloiulini" investigated here within a phylogenetic framework of julid taxa, and traced the evolutionary history of ethyl-benzoquinones in typhloiulines in relation to cave-dwelling. The results indicated a cave-independent evolution of ethyl-substituted benzoquinones, indicating the absence of a "cave effect" on the secretions of troglobiont Typhloiulini. Ethyl-benzoquinones probably evolved early in an epi- or endogean ancestor of a clade including several, but not all Typhloiulus (basically comprising a taxonomic entity known as "Typhloiulus sensu stricto") and Serboiulus. Ethyl-benzoquinones are proposed as novel and valuable chemical characters for julid systematics.

AB  - Chemistry has been used as a tool of war for thousands of years. The earliest tools were poisoned arrows, Greek fire, water poisoning by hellebore plant extracts, etc. Apart from the chemicals used in the early wars, the modern chemical weapons (CW) were created during WWI and took more than one hundred thousand lives and caused around million casualties. Today CW have been regulated/prohibited by the Chemical Weapons Convention (OPCW, 2005) signed by 192 state parties. The implementing body for CWC is the Organisation for the Prohibition of Chemical
Weapons (OPCW). Nowadays, when fear of terrorism is bigger than ever, society needs a better insight into CW, safety and widely used industrial chemicals with terrible potential. In the current curriculum CW is studied mostly from military point of view and the focus is more on the weapons than on chemistry. Authors suggest that the development of chemical weapon related courses in a chemistry curriculum could be a way to achieve safer society. CW courses could cover different topics, e.g. ethics in science, history of chemistry, safety in chemistry and chemical industry, organic and bioorganic chemistry, biochemistry, analytical chemistry, environmental and industrial
chemistry, multiple usage chemicals, green chemistry as an alternative to widely used CW related chemicals, etc. Development of a CW syllabus could be supported by various internet-based resources used for education for peace (www.opcw.org/specialsections/education, http://multiple.kcvs.ca, www.thefiresproject.com). Diversity of chemicals covered by CWC in combination with multi-disciplinary approach is a great foundation for development of different student skills: science ethics, problemsolving skills, safety skills, 21st century searching skills, team skills… The authors created a new graduate course called Chemical weapons at Faculty of Chemistry, University of Belgrade in 2016/17. The syllabus of CW can be seen on the internet
(www.chem.bg.ac.rs/predmeti/279H1-en.html). In conclusion, the chemistry behind chemical weapons is quite diverse and the authors suggest that undergraduate or graduate course Chemical weapons could be very interesting and beneficial for both chemistry major/minor students.

AB  - Samples of the selected red wine varieties grown in Montenegro (Merlot, Cabernet Sauvignon and Vranac; vintages 2010-2012) were compared according to total phenolic content, anti-DPPH radical activity, phenolic profile and elemental composition. All the samples showed profound anti-DPPH radical activity, due to high content of total phenolic compounds (R=0.92). The most abundant phenolics were catechin and gallic acid with the highest values recorded for Merlot 2012 (43.22 and 28.65mg/L, respectively). In addition to this, the content of essential elements including the potentially toxic ones was within healthy (safe) level for all the samples analysed. This study has actually pointed out Merlot wine variety as the best quality one, though all three varieties may be used as safe and health-promoting nutritional products. [GRAPHICS] .

AB  - The variations of metabolic profile of the latex of wild-growing Euphorbia palustris was carried out using multivariate analysis of NMR spectral data. One population was infected with fungi Fusarium sporotrichioides, Fusarium proliferatum and Alternaria alternata, while the other consisted of healthy plant species. The non-polar metabolites of latex extracts such as benzoyl ingenol-laurate, amyrin decadienoate esters, cis-1,4-polyisoprene, and 24-methylenecycloartanol were identified using H-1 and 2D NMR spectra. Principal component analysis of H-1 NMR data provided a clear discrimination between the latex of infected and healthy plants. Minimum inhibitory concentration and minimum fungicidal concentration values of the latex extracts of healthy and infected plants were determined. The latex of infected plants was found to contain higher levels of benzoyl ingenol-laurate and 24-methylenecycloartanol, of which concentrations were strongly correlated with the antifungal activities of the latex.

AB  - Cuticular hydrocarbons (CHCs) in Drosophila melanogaster represent the basis of chemical communication being involved in many important biological functions. The aim of this study was to characterize chemical composition and variation of cuticular profiles in five D. melanogaster strains. These strains were reared for approximately 300 generations on five diets: standard cornmeal medium and substrates prepared with apple, banana, tomato, and carrot. Differences in quantity and/or quality in CHCs were assumed as a result of activation of different metabolic pathways involved in food digestion and adaptations to the particular diet type. In total, independently of sex and strain, 66 chemical compounds were identified. In females of all strains, 60 compounds were identified, while, in males, 47 compounds were extracted. Certain new chemical compounds for D. melanogaster were found. MANOVA confirmed that CHC amounts significantly depend on sex and substrates, as well as on their interactions. Discriminant analysis revealed that flies belonging to apple' and carrot' strains exhibited the most noticeable differences in CHC repertoires. A non-hydrocarbon pheromone, cis-vaccenyl acetate (cVA) also contributed to the variation in the pheromone bouquet among the strains. Variability detected in CHCs and cVA may be used in the explanation of differences in mating behaviour previously determined in analyzed fly strains.

AB  - Diarylheptanoids represent a group of plant secondary metabolites that possess multiple biological properties and are increasingly recognized for their therapeutic potential. A comparative study was performed on structurally analogous diarylheptanoids isolated from the bark of green (Alnus viridis) and black alder (Alnus glutinosa) to address their biological effects and determine structure-activity relationship. The structures and configurations of all compounds were elucidated by NMR, HR-ESI-MS, UV and IR. Diarylheptanoids actions were studied in human non-small cell lung carcinoma cells (NCI-H460) and normal keratinocytes (HaCaT). A. viridis compounds 3v, 5v, 8v and 9v that possess a carbonyl group at C-3 were considerably more potent than compounds without this group. A. viridis/A. glutinosa analogue pairs, 5v/5g and 9v/9g, which differ in the presence of 30 and 300-OH groups, were evaluated for anticancer activity and selectivity. 5v and 9v that do not possess 30 and 300-OH groups showed significantly higher cytotoxicity compared to analogues 5g and 9g. In addition, these two A. viridis compounds induced a more prominent apoptosis in both cell lines and an increase in subG0 cell cycle phase, compared to their A. glutinosa analogues. 5v and 9v treatment triggered intracellular superoxide anion accumulation and notably decreased mitochondrial transmembrane potential. In HaCaT cells, 9v and 9g with a 4,5 double bond caused a more prominent loss of mitochondrial transmembrane potential compared to 5v and 5g which possess a 5-methoxy group instead. Although green alder diarylheptanoids 5v and 9v displayed higher cytotoxicity, their analogues from black alder 5g and 9g could be more favorable for therapeutic use since they were more active in cancer cells than in normal keratinocytes. These results indicate that minor differences in the chemical structure can greatly influence the effect of diarylheptanoids on apoptosis and redox status and determine their selectivity towards cancer cells.

Diarylheptanoids actions were studied in human non-small cell lung carcinoma cells (NCI-H460) and normal keratinocytes (HaCaT). A. viridis compounds 3v, 5v, 8v and 9v that possess a carbonyl group at C-3 were considerably more potent than compounds without this group. A. viridis/A. glutinosa analogue pairs, 5v/5g and 9v/9g, which differ in the presence of 30 and 300-OH groups, were evaluated for anticancer activity and selectivity. 5v and 9v that do not possess 30 and 300-OH groups showed significantly higher cytotoxicity compared to analogues 5g and 9g. In addition, these two A. viridis compounds induced a more prominent apoptosis in both cell lines and an increase in subG0 cell cycle phase, compared to their A. glutinosa analogues. 5v and 9v treatment triggered intracellular superoxide anion accumulation and notably decreased mitochondrial transmembrane potential. In HaCaT cells, 9v and 9g with a 4,5 double bond caused a more prominent loss of mitochondrial transmembrane potential compared to 5v and 5g which possess a 5-methoxy group instead. Although green alder diarylheptanoids 5v and 9v displayed higher cytotoxicity, their analogues from black alder 5g and 9g could be more favorable for therapeutic use since they were more active in cancer cells than in normal keratinocytes. These results indicate that minor differences in the chemical structure can greatly influence the effect of diarylheptanoids on apoptosis and redox status and determine their selectivity towards cancer cells.

AB  - The composition and content of individual phenolic compounds in various fruit wines and overall antioxidant properties of these fruit wines were studied. Phenolic compounds were separated by reverse phase (RP) HPLC techniques, and their content was determined by means of mass spectrometer (MS) with triple quadrupole (TQ) analyser, which recorded specific precursor-product transitions. Antioxidant activity was monitored by the following spectrophotometric methods: DPPH, FRAP and Folin-Ciocalteu assay, respectively. Four types of berries (raspberry, blackberry, chokeberry and blueberry), one type of pome (apple) and one type of stone fruit (cherries) were used for the production of fruit wines. Corresponding fruit wines were produced by microvinification with or without adding sugar into the must before fermentation. Increase in alcohol level was responsible for the increased content of phenolic compounds in fruit wine due to improved extraction conditions. Produced fruit wines were preserved by adding SO2 which interferes with the determination of antioxidant activity of phenolic compounds. In this case, the development of a correlation method based on FRAP assay was introduced. Fruit wines are a rich source of substances which show beneficial effects on human health. Depending on the fruit type, different antioxidant compounds were predominant in wine samples.

AB  - Through the selected examples of different classes of secondary metabolites two general approaches in the analysis of complex mixtures of natural products are presented. The first one involves isolation of the constituents using optimized semi-prep LC in combination with classical column chromatography (CC) and the second one represents direct (on-line) analysis of complex plant extracts prior to isolation of the constituents. Thus the isolation of mg-quantities of jatrophanes the bioactive constituents of Euphorbia dendroides, with their structure determination on the basis of spectroscopic data interpretation (IR, NMR, MS), is described. The direct analysis of the plant extracts is demonstrated by the characterization of antioxidative polyphenols, i.e. oligomeric proanthocynidins from the MeOH extracts of grape Vitis vinifera seeds by the application of hyphenated methods (LC/UV/MS) in combination with 13C NMR spectroscopy, as well as tandem mass spectrometry (MS/MS) and MSn in combination with and without LC for identification of oligomeric proanthocynidins from other sources. The potential of another hyphenated instrumentation, LC/UV/SPE-NMR is shown by on-line identification of the various constituents of the crude extract of Hypericum perforatum. The possibilities and limitations of the NMR technique named diffusion ordered spectroscopy (DOSY) for direct analysis of the complex mixture, such as e.g. methanolic extract of Gentiana lutea, is discussed.

AB  - Procedure for isolation of pyrrolizidine alkaloids (PAs) from Rindera umbellata Bunge plant species was optimised. Different extraction media (methanol, ethanol and sulphuric acid), concentration and volume of sulphuric acid, pH of PA solution for alkaline extraction, extraction time and techniques (maceration, ultrasonic and overhead rotary mixer assisted extraction) were investigated. The yields of six PAs (7-angeloyl heliotridane, 7-angeloyl heliotridine, lindelofine, 7-angeloyl rinderine, punctanecine and heliosupine) were monitored by GC-MS/FID. The best results for the isolation all of six PAs were obtained when the extraction was performed with 1M sulphuric acid (30mL per 1.00g of dried sample) by overhead rotary mixer during three days. Optimal pH value for alkaline extraction of PAs with CH2Cl2 was 9, and the extraction should be performed with four portions of 30mL of CH2Cl2. This procedure could be also useful for a plant sample preparation for GC and LC analyses of PAs.

AB  - The composition of essential oil isolated from the areal parts of Aster albanicus Deg, an endemic species of the central Balkans, was analyzed. In total, 111 compounds were identified, representing 98% of the essential oil. The essential oil was dominated by sesquiterpene (69.3%) and monoterpene hydrocarbons (15.9%), with germacrene D as the most abundant compound (34.7%). Several multivariant statistical methods (HCA, NJ, PCoA) were deployed to infer the relation between A. albanicus and other species belonging to this genus. Taxonomical implications are discussed.
