AB  - Euphorbia cyparissias L. (cypress spurge) is one of the many species of the genus Euphorbia. Like other plant species of the genus, E. cyparissias is a source of biologically active compounds [1, 2]. The aim of this research was to profile the chloroform-methanol latex extract and detect the type of secondary metabolites of Serbian E. cyparissias, collected in Deliblato Sand 
(Serbia) in May 2022, using liquid chromatography – electrospray ionisation mass spectrometry. Based on the obtained results, terpene derivatives have been found as the most abundant in the latex extract, mainly diterpenes (jatrophanes and ingenanes) and triterpenes. Also, the anticancer activ ity of the latex extract on the cell lines NCI-H460, NCI-H460/R, U87, U87/
TxR and MRC-5, as well as the ability to inhibit P-gp, were examined. Latex extract exhibited anticancer activity against all tested cell lines, and also 
proved to be a strong P-gp inhibitor. The obtained results are in accordance with the literature data because jatrophanes are well-known strong P-gp 
inhibitors [3]. These preliminary results indicate that this plant material is a rich source of biologically active compounds and detailed phytochemical research of E. cyparissias is further planned.

AB  - The genus Euphorbia represents one of the largest and most diverse plant genera. Plant species of this genera are a rich source of biologically active compounds. Our previous investigation of E. palustris L. revealed an excellent anti-melanoma activity of 3β-benzoyloxy-13α-dodecanoyloxy-ingenol (1), and 3β,13α,17-tribenzoyloxy-ingenol (2), significantly better than ingenol-mebutate (Picato®), a commercial anti-melanoma agent approved by the U.S. Food and Drug Administration (FDA) and by the European Medicines Agency (EMA) for the topical treatment of actinic keratosis [1]. Hence, in this research, using liquid chromatography–electrospray ionization mass spectrometry, chloroform-methanolic extracts of two samples of E. palustris collected at different localities in Serbia were analysed in order to confirm the presence of 1.Based on the tentative analysis of the LC-HRESI-MS and the previous examination of this plant species, ingenanes 1 and 2 were confirmed in both extracts examined. Additionally, both extracts contained several metabolites that structurally corresponds to ingenol, with a decanoyl group in their structure. Based on these preliminary results, our goal in further investigation is to isolate other ingenane molecules and test their anti-melanoma activity.

AB  - Bisbibenzyls represent chemical class of compounds containing two bibenzyl units mutually connected by an oxygen atom and/or directly by the “C-C” bonds. They are chemical markers of liverworts, the ancestors of higher vascular plants. Marchantin A from Marchantia polymorpha was the first discovered bisbibenzyl. More than 120 chemically characterized bisbibenzyls 
were reported up to 2020 with numerous biological activities [1]. The first report on bisbibenzyls in higher (vascular) plants was published in 2007, when 
Kosenkova et al. (2007) isolated riccardin C in Primula veris subsp. macrocalyx from Mt. Altay in Russia as the dominant compound in the extract of the whole plant [2]. In the repeated study of the same species, Kosenkova et al. (2009) confirmed their findings discovering an additional bisbibenzyl constituent, perrottetin E [3].
In this investigation from the CH2Cl2/CH3OH (1:1) extract of the air-dried, powdered roots nine isbibenzyls, five new, have been isolated from P. veris subsp. columnae and P. acaulis using dry column flash chromatography followed by semipreparative HPLC chromatography and identified on the basis of 1D and 2D NMR, IR, UV and HRESIMS data. This investigation widens the knowledge about the presence of bisbibenzyls in vascular plants since only two bisbibenzyls have been previously found in vascular plants, in Primula veris subsp. macrocalyx.

AB  - The diversity of plant species from the genus Euphorbia and wide variety of secondary metabolites they produce contributed to their successful use in the traditional medicine all over the world. Therapeutic applications have been attributed to different compounds such as diterpenes and triterpenes. Previous investigations revealed that Euphorbia diterpenes possess a variety of biological activities such as anti-inflammatory, antitumor and antiviral. Some of them showed that tigliane diterpenes, beside other potential pharmaceutical activities, inhibited wild-type HIV-1 and HIV-2 strains as well as drug resistant strains of HIV 1 and that they exhibited low cytotoxicity. Two tigliane diterpenes were 
isolated from the latex of E. lucida, using classical and instrumental chromatographic techniques. ESI-HRMS spectra showed that both isolated compounds possess the same molecular formula (C31H38O6). 1D NMR spectra revealed benzoate and isobutanoate ester groups in both molecules, Using HMBC spectra their position was determined: C-13 for isobutanoate and C-20 for benzoate. Exact configurations were discovered by NOE correlations. It was concluded that these two molecules differ in the way of the binding the five-membered and seven-membered rings, i.e., that these two molecules are C-4-epimers. Compound 1 (20-benzoyloxy-13α-isobutanoyloxy-4,12-dideoxyphorbol) was already described in the literature as a metabolite of E. pannonica [1], while compound 2 (20-benzoyloxy-13α-isobutanoyloxy-4-epi-4,12-dideoxyphorbol) represents a new tigliane derivative.

AB  - Bisbibenzyls are specialized metabolites found exclusively in liverworts, until recently; they represent chemical markers of liverworts. Their occurrence in vascular plants was noticed in 2007, when they were found in Primula veris subsp. macrocalyx from Russia. This report prompted us to chemically analyze the two most common Serbian Primula species, P. veris subsp. columnae and P. acaulis, in order to determine the presence of bisbibenzyls in them. Our study revealed nine structurally distinct bisbibenzyls (1–9), identified based on 1D and 2D NMR, IR, UV and HRESIMS data. Among them were five previously undescribed compounds (2–6). The remaining com­ pounds found and previously described in the literature were: the bisbibenzyls riccardin C (1), isoperrottetin A (7), isoplagiochin E (8) and 11-O-demethylmarchantin I (9), as well as 4-hydroxyphenylmethylketone (10) and 4-hydroxy-3-methoxyphenylmethylketone (11). Riccardin C was the most dominant bisbibenzyl in both species studied. Previously, it was the first bisbibenzyl found in vascular plants (P. veris subsp. macrocalyx). An assessment of the cytotoxic activity of the isolated compounds against A549 lung cancer and healthy MRC5 cell lines was also the subject of our study. Compounds 6 and 9 exhibited significant cytotoxic activity expressed by IC50 values of 12 μM, but the selectivity was not satisfactory.

AB  - Background and objective: Cotinus coggygria Scop. is a valuable medicinal  plant species with pronounced pharmacological potential due to its numerous biological  activities. The herb is characterized by a high content of polyphenols among which is fustin.  The anticancer activities of fustin, however, are extremely weakly studied. The aim of the  present study was to investigate the in vitro antiproliferative potential of fustin isolated from  the heartwood of C. coggygria against cell lines originating from two of the most common  cancer types – breast (MDA-MB-231 and MCF7), and colon cancer (Colon 26). Materials  and methods: Cell growth inhibitory properties of fustin were examined by MTT assay.  Subsequently, phase-contrast and fl uorescence microscopy analysis as well as colonyforming assay were carried out on the most sensitive to the cytostatic action of the fustin  cell line. Results: The obtained results showed that fustin reduced the proliferation of  all studied cell lines. The highest cytostatic eff ect was registered towards breast cancer  MDA-MB-231 cells with a half maximal inhibitory concentration (IC50) value of 56.02 μg/ ml followed by colon cancer cells with an IC50 of 78.07 μg/ml. MCF7 cell proliferation was  least aff ected with a calculated IC50 of 187.8 μg/ml. Further investigations on breast cancer  MDA-MB-231 cells indicated decreased density of cell monolayer and some morphological  alterations, signifi cant attenuation in the number of viable cells, and diminished clonogenic  ability of cells after fustin exposure. Conclusion: It could be concluded that fustin isolated  from the heartwood of medicinal plant C. coggygria possesses marked antiproliferative  properties against breast cancer cell line MDA-MB-231 which will be a subject of our more  detailed future investigations.

AB  - The synthesis of 24 hybrid molecules, consisting of naturally occurring sclareol (SCL) and synthetic 1,2,4-triazolo[1,5-a]pyrimidines (TPs), is described. New compounds were designed with the aim of improving the cytotoxic properties, activity, and selectivity of the parent compounds. Six analogs (12a-f) contained 4-benzylpiperazine linkage, while 4-benzyldiamine linkage was present in eighteen derivatives (12g-r and 13a-f). Hybrids 13a-f consist of two TP units. After purification, all hybrids (12a-r and 13a-f), as well as their precursors (9a-e and 11a-c), were tested on human glioblastoma U87 cells. More than half of the tested synthesized molecules, 16 out of 31, caused a significant reduction of U87 cell viability (more than 75% reduction) at 30 µM. The concentration-dependent cytotoxicity of these 16 compounds was also examined on U87 cells, corresponding multidrug-resistant (MDR) U87-TxR cells with increased P-glycoprotein (P-gp) expression and activity, and normal lung fibroblasts MRC-5. Importantly, 12l and 12r were active in the nanomolar range, while seven compounds (11b, 11c, 12i, 12l, 12n, 12q, and 12r) were more selective towards glioblastoma cells than SCL. All compounds except 12r evaded MDR, showing even better cytotoxicity in U87-TxR cells. In particular, 11c, 12a, 12g, 12j, 12k, 12m, 12n, and SCL showed collateral sensitivity. Hybrid compounds 12l, 12q, and 12r decreased P-gp activity to the same extent as a well-known P-gp inhibitor - tariquidar (TQ). Hybrid compound 12l and its precursor 11c affected different cellular processes including the cell cycle, cell death, and mitochondrial membrane potential, and changed the levels of reactive oxygen and nitrogen species (ROS/RNS) in glioblastoma cells. Collateral sensitivity towards MDR glioblastoma cells was caused by the modulation of oxidative stress accompanied by inhibition of mitochondria.

AB  - The synthesis of 17 hybrid molecules, consisting of artesunate, a derivative of naturally occurring artemisinin, and synthetic 4-aryl-2-aminopyrimidines, is described. New compounds were designed to improve the parent compounds' cytotoxic properties, activity, and selectivity. The synthesized hybrid molecules (15a–f with ethylenediamine linker and 16a–k with piperazine linker), as well as their precursors – pyrimidine derivatives (13a–f and 14a–k), artemisinin, and artesunate, were tested on sensitive and multidrug-resistant (MDR) human non-small cell lung carcinoma (NSCLC) cells. All hybrid compounds with piperazine linker 16a–k were selective toward NSCLC cells and displayed IC50 values below 5 μM. Although they showed similar anticancer potency as artesunate, their selectivity against cancer cells was considerably improved. Importantly, 16h–k hybrid compounds were able to evade MDR phenotype, inhibit P-glycoprotein (P-gp) activity, and increase the sensitivity of MDR NSCLC cells to doxorubicin (DOX). The inhibition of P-gp activity induced by 16h–j was stronger than the one obtained with artesunate. Among these four hybrid compounds, 16k was the most potent anticancer agent with similar IC50 values of around 1.5 μM (for comparison – over 3.1 μM for artesunate) in sensitive and MDR NSCLC cells.

AB  - The Marchantiophyta (liverworts) are rich sources of phenolic substances, especially cyclic and acyclic bis-bibenzyls, which are rare natural products in the plant kingdom, together with bibenzyls and characteristic terpenoids. At present, more than 125 bis-bibenzyls have been found in liverworts. They are biosynthesized from the dimerization of lunularic acid via dihydrocoumaric acid and prelunularin. The structurally unusual cyclic and acyclic bis-bibenzyls show various biological activities such as antimicrobial, antifungal, cytotoxic, muscle relaxation, antioxidant, tubulin polymerization inhibitory, and antitrypanosomal activities, among others. The present review article deals with the distribution and structure of bis-bibenzyls, bibenzyls, and several characteristic ent-sesqui- and diterpenoids in liverworts. Furthermore, the biosynthesis and total syntheses and biological activities of bis-bibenzyls are also surveyed.

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  - Thirteen undescribed 24-methylene lanostane triterpenoids, named polyporenic acids E-M and fomitosides L-O, as well as seventeen known analogues, were isolated from the fruiting bodies of the mushroom Fomitopsis betulina. Their structures were determined using 1D, 2D NMR, IR, and HRESIMS. Fomitoside L and fomitoside N exhibited cytotoxicity against HL60 leukemia cells (IC50 = 15.8 and 23.7 μM, respectively). Among the known compounds, notable cytotoxicities against HL60 leukemia cells and selectivity with respect to MRC-5 healthy cells were noticed for dehydropachymic acid (IC50 = 10.9 μM, SI 8.6), pachymic acid (IC50 = 11.0 μM, SI 9.8), 3-epi-dehydrotumulosic acid (IC50 = 19.9 μM, SI 5.8) and 12α-hydroxy-3α-(3′-hydroxy-4′-methoxycarbonyl-3′-methylbutyryloxy)-24-methyllanosta-8,24 (31)-dien-26-oic acid (IC50 = 19.2 μM, SI 2.2).

AB  - Eleven 31-methylenlanostane triterpenoids, i.e., seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina, were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (CBMN) assay. Most of the tested compounds showed a beneficial effect by reducing DNA damage of human lymphocytes more effectively than amifostine, a radioprotective agent, used as a positive control. All the tested compounds decreased MN frequency in the concentration dependent manner, with the concentration of 2.0 µg mL-1 being the most effective – with increase of the concentration the activity slightly decreases. The structure–activity relationship (SAR) studies indicated that the lanostanes containing a conjugated 7,9 (11)-diene system exhibit lower activity than Δ8-analogues. It was also demonstrated that the DNA protective activities within the Δ8-lanostane-26-oic acid group are affected by the substitution in position 3 pattern. In the Δ8 series the oxygenation at C-12 or 16 as well as 21- or 26-oic acid functionality proved beneficial for in vitro protective effect on chromosomal aberrations. Betulin exhibited the lowest protective activity, but it is still comparable to that of amifostine.

AB  - In continuation of our study on Cotinus coggygria from Serbia, 10 known flavonoids (1-10) were isolated from the methylene chloride/ methanol extract of the heartwood. They were tested for in vitro protective effect against chromosome aberrations in peripheral human lymphocytes, using the cytokinesis-block micronucleus assay. All tested compounds (in minimal doses of 1 μg/mL) exerted a beneficial effect by decreasing DNA damage of human lymphocytes in the range of 24.2% to 54.5%, better than the radio protectant control, amifostine. Functional groups, such as 3′,4′-dihydroxyphenyl (catechol), 5-OH, 3-OH, and 4-keto in flavonoids (3-keto in aurones), which play a key role in antioxidant activity, are proposed to be responsible for the DNA protective activity of the tested compounds.

AB  - Tumor is one of the leading diseases of today. Chemotherapy and radiation therapy healing chances are limited, so some alternative methods are resorted to. Many papers indicated that garlic and organosulphur compounds diallyldisulphide (DADS) and diallyltrisulphide, which are main components of garlic decrease the cancer risk and inhibit the cell proliferation. In this paper inhibition potency of disulphides (DADS and its synthetic analogues) and trisulphides with different alkyl and phenyl substituents on growth of various tumor (Non-Small cell Lung Cancer, Colon cancer, CNS Cancer, Melanoma, Ovarian Cancer, Renal Cancer, Prostate Cancer, Breast Cancer, Leukemia) cell lines was investigated. Concentration of each compound (DADS, diethyl disulphide, dipropyl disulphide, diphenyl disulphide, tetraethylthiuram disulphide (TETUDS), dimetil trisulphide, dipropyl trisulphide and metilpropyl trisulphide (MPTS) was 10 µmol/L. It was found that DADS has an inhibitory effect on the growth of several cancer cell lines, but synthetic analogues TETUDS and MPTS exhibit stronger effect on certain cells lines. MPTS inhibits the growth of even 12 cell lines for more than 10%, especially leukemia cell line SR and NCI-H522 cell line of Non-Small cell Lung Cancer (reduction of growth for 24% and 47%, resp.). Trisulphide analogues exhibit little higher inhibitory effects in comparison to disulphide ones.

AB  - Based on previous investigations where bis-bibenzyls isolated from liverworts showed various biological activities (cytotoxic, antimicrobial, and antiviral), we investigated their cytotoxic activity in several human cancer cell lines. From the methylene-chloride/methanol extract of the liverwort Pellia endiviifolia, three bis-bibenzyls of the perrottetin type were isolated, namely perrottetin E, 10′-hydroxyperrottetin E, and 10,10′-dihydroxyperrottetin E. The last two were found for the first time in this species. Their structures were resolved using 1D and 2D NMR, as well as by comparison with data in the literature. Cytotoxic activity of the isolated compounds was tested on three human leukemia cell lines, HL-60 (acute promyelocytic leukemia cells), U-937 (acute monocytic leukemia cells), and K-562 (human chronic myelogenous leukemia cells), as well as on human embryonal teratocarcinoma cell line (NT2/D1) and human glioblastoma cell lines A-172 and U-251, and compared to the previously isolated bis-bibenzyls (perrottetins) of similar structure. The isolated compounds exhibited modest activity against leukemia cells and significant activity against NT2/D1 and A-172. Overall, the most active cytotoxic compounds in this investigation were perrottetin E (1), isolated in this work from Pellia endiviifolia, and perrottetin F phenanthrene derivative (7), previously isolated from Lunularia cruciata and added for a comparison of their cytotoxic activity.

AB  - The antimicrobial activity of methanol extracts of three thalloid liver­worts, Marchantia polymorpha, Conocephalum conicum and Pellia endiviifolia and bis-bibenzyl marchantin A, the most dominant compound in the methanol extract of M. polymorpha, have been investigated in this research. 1H-NMR spec­troscopy revealed that the M. polymorpha and P. endiviifolia extracts of liverwort contain terpenes, oils, sugars and bis-bibenzyls, while these specific macrocyclic compounds were absent in the C. conicum extract. The anti­mic­robial potential was tested on eight bacterial strains. Antimicrobial effects of extracts and mar­chantin A were observed against Gram-positive bacteria, while they showed no effect against Gram-negative bacteria in both methods used – well diffusion and broth microdilution.
AB  - У овом раду испитиван је хемијски састав и антибактеријска активност метанолних екстраката три јетрењачe, Marchantia polymorpha, Conocephalum conicum и Pellia endiveifolia и бис-бибензила маршанцина A, доминантне компоненте у метанолном екстракту M. polymorpha. 1H-NMR спектроскопија је показала присуство терпена, уља, шећера и бис-бибензила у екстрактима M. polymorpha и P. endiviifolia, док екстракт C. conicum не садржи специфична макроциклична једињења – бис-бибензиле. Антимикробни потен- цијал је тестиран на осам бактеријских сојева. Антимикробни ефекат маршанцина А уочен је на све грам позитивне сојеве, док је ефекат изостао код грам негативних сојева у обе тестиране методе – дифузионе методе у бунарима и микродилуционе методе у хранљивом бујону.

abstract = "The antimicrobial activity of methanol extracts of three thalloid liver­worts, Marchantia polymorpha, Conocephalum conicum and Pellia endiviifolia and bis-bibenzyl marchantin A, the most dominant compound in the methanol extract of M. polymorpha, have been investigated in this research. 1H-NMR spec­troscopy revealed that the M. polymorpha and P. endiviifolia extracts of liverwort contain terpenes, oils, sugars and bis-bibenzyls, while these specific macrocyclic compounds were absent in the C. conicum extract. The anti­mic­robial potential was tested on eight bacterial strains. Antimicrobial effects of extracts and mar­chantin A were observed against Gram-positive bacteria, while they showed no effect against Gram-negative bacteria in both methods used – well diffusion and broth microdilution., У овом раду испитиван је хемијски састав и антибактеријска активност метанолних екстраката три јетрењачe, Marchantia polymorpha, Conocephalum conicum и Pellia endiveifolia и бис-бибензила маршанцина A, доминантне компоненте у метанолном екстракту M. polymorpha. 1H-NMR спектроскопија је показала присуство терпена, уља, шећера и бис-бибензила у екстрактима M. polymorpha и P. endiviifolia, док екстракт C. conicum не садржи специфична макроциклична једињења – бис-бибензиле. Антимикробни потен- цијал је тестиран на осам бактеријских сојева. Антимикробни ефекат маршанцина А уочен је на све грам позитивне сојеве, док је ефекат изостао код грам негативних сојева у обе тестиране методе – дифузионе методе у бунарима и микродилуционе методе у хранљивом бујону.",

AB  - Liverworts are characterized by a high content of bioactive compounds reported to show antimicrobial, anticancer, and antioxidant properties. In this study, the biological effects of the methanol extract of the liverwort Pellia endiviifolia and its constituents, bis-bibenzyls perrottetin E, 10′-hydroxyperrottetin E, and 10,10′-dihydroxyperrottetin E, were investigated using human peripheral blood cells as a model system. The assessment of the investigated compounds comprised testing their genotoxicity, apoptotic potential, and redox modulating activities. The genotoxicity testing indicated that medium (25 µM) and high concentrations (100 µM) of the investigated compounds displayed genotoxic and antiproliferative effects in human lymphocytes as revealed by significant, concentration-dependent enhancement of the micronuclei incidence and decrease in the cytokinesis-block proliferation index compared to the control (P <.001). Analysis of leukocyte apoptosis showed a substantial potential of all investigated compounds to induce apoptosis, which was not concentration-dependent. The P endiviifolia extract and perrottetin E demonstrated considerable pro-apoptotic potential, even at the lowest concentration (1 µM) applied. Evaluation of the redox modulating effects, which comprised measuring erythrocyte catalase activity and the lymphocyte malondialdehyde level, showed that the investigated compounds did not induce oxidative stress in human peripheral blood cells (P >.05). The observed genotoxic, antiproliferative, and proapoptotic effects of the investigated compounds make them suitable for further comprehensive studies related to their possible applications as anticancer agents.

AB  - Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative HPLC and their structures were established to be 8-hydroxyperrottetin F, C-7-C-8 cleaved product, and perrottetin F 6’-sulfate using 1D and 2D NMR, HR-ESI-MS, IR and UV spectroscopy. The antimicrobial and cytotoxic properties of these compounds were also evaluated. Given the suggested cytotoxic properties of the parent compound, antiproliferative activity against healthy human lung fibroblasts (MRC5) and human lung carcinoma (A549) of three metabolites were evaluated revealing their lower cytotoxic properties in comparison to the starting compound-perrottetin F. The antimicrobial properties of these compounds were also evaluated, with the inhibitory activity against the Pseudomonas aeruginosa PAO1 and Staphylococcus aureus determined between 100 µM and 450 µM. The metabolites showed remarkable ability to inhibit synthesis of bacterial quorum-sensing signal molecules such as short chain acyl homoserine lactones (AHLs). Therefore, biotransformation method represents fast and effective tool for obtaining new bioactive structures.

AB  - Lamiaceae (Labiatae) are an important group of medicinal plants, which have been used for treating heart disease in traditional medicine for centuries. These mainly aromatic plants are used as essential oils, extracts or isolated components (polyphenols, phenolic compounds, terpenes, iridoids etc.). Some Labiatae species (more than 30, such as cornmint, lavender, patchouli, rosemary etc.) are famous for their use in essential oil production worldwide. In this review, cardioprotective effects of Lamiaceae and their active secondary metabolites, as well as mechanism of action against cardiovascular diseases (hypertension, angina pectoris, hyperlipidemia, thromboembolism, coronary heart disease, heart failure, venous insufficiency, arrhythmia) will be discussed. Use of Labiatae as food or food additives (such as spices) may prevent risk of cardiovascular diseases, diabetes and cancer. This approach is also described as a part of the article. Studies on developing new, effective and safe natural products from Lamiaceae (rich source of flavonoids and other active compounds) are promising and may offer prevention and treatment for patients with coronary disease and other related diseases.

AB  - Natural products represent a key source of novel drug leads and their essential value in anticancer research is being increasingly recognized. The presence, quantity, and structural characteristics of natural compounds within the same species could differ between regions as a result of environmental variations contributing to intraspecific chemodiversity. The Balkan Peninsula is a vital part of Europe’s biodiversity, with a considerable number of endemic species and with a broad ecosystem distribution. This region provides an unlimited supply of unique, structurally diverse compounds and offers vast potential for discovering and developing therapeutics for human benefit. This chapter gives an overview of anticancer compounds derived from natural sources of the Balkans and underlines the importance for the long-term conservation of biodiversity in this part of Europe.

AB  - Chemical and biocatalytic synthesis of seven previously undescribed marchantin A ester derivatives has been presented. Chemical synthesis afforded three peresterified bisbibenzyl products (TE1-TE3), while enzymatic method, using lipase, produced regioselective monoester derivatives (ME1-ME4). The antiproliferative activities of all prepared derivatives of marchantin A were tested on MRC-5 healthy human lung fibroblast, A549 human lung cancer, and MDA-MB-231 human breast cancer cell lines. All tested esters were less cytotoxic in comparison to marchantin A, but they also exhibited lower cytotoxicity against healthy cells. Monoesters displayed higher cytotoxic activities than the corresponding peresterified products, presumably due to the presence of free catechol group. Monohexanoyl ester ME3 displayed the same IC50 like marchantin A against MDA-MB-231 cells, but the selectivity was higher. In this way, regioselective enzymatic monoesterification enhanced selectivity of marchantin A. ME3 was also the most active among all derivatives against lung cancer cells A549 with the slightly lower activity and selectivity in comparison to marchantin A.
