AB  - Biogenic amines are integral part of nearly every cell. In the present study, the method of acidic extraction of histamine (His), of polyamines putrescine (Put), spermidine (Spd) and catecholamines epinephrine (Epi) and norepinephrine (NE) from human serum, precolumn derivatization with dansyl chloride, and LC/DAD analysis of the biogenic amines was used with the aim of monitoring differences of their levels in patients with diabetes mellitus, chronic urticaria, and Hashimoto's thyroiditis, compared to healthy subjects, and to observe them as possible markers for immune mediated diseases. The retention times were used for the determination of serum biogenic amines. Statistically significant differences were found in the levels of putrescine and histamine in diabetes mellitus patients, of the levels of putrescine, histamine, spermidine and epinephrine in chronic urticaria patients and of the levels of putrescine and spermidine levels in Hashimoto's thyroiditis patients, compared to those of healthy controls. Norepinephrine was found only in the serum of patients with chronic urticaria. The values of recovery, evaluated in controls, varied between 85.7 and 106.7 %. The statistically significant changes in putrescine, histamine, spermidine and epinephrine levels in patients compared with those in healthy people reflects the existence of biochemical disturbances in the mentioned immune-mediated diseases.

AB  - The in vitro cytotoxic activity of previously synthesized steroid dimers with different spacer group (sulfide, trithiolane ring or phosphorotrithioate) and the substituent at C-17 position was tested for their possible effects against following human tumor cell lines: cervical adenocarcinoma (HeLa), chronic myelogenous leukemia (K562) and two human breast cancer cell lines (MDA-MB-361 and MDA-MB-453). These compounds, applied at micromolar concentrations, exhibited cytotoxic activity of different intensity (compared with cisplatin as a control), modality and selectivity in these malignant cell lines. The best activity against all four cell cancer lines was exhibited by dimer-sulfides. All screened compounds exerted concentration-dependent cytotoxic activity against leukemia K562 cells. The compounds which exerted the most pronounced cytotoxic action exhibited notably higher cytotoxic activities against K562, HeLa and MDA-MB-453 cells in comparison to resting and PHA-stimulated PBMC, pointing to a significant selectivity in their antitumor actions. Examination of the mechanisms of cytotoxicity on leukemia K562 cells revealed pro-apoptotic action of each of the investigated compounds applied at concentrations 2IC(50). The most prominent pro-apoptotic action was exhibited by dimer-sulfide of cholest-4-en-3-one. Furthermore, almost all of the tested compounds at IC50 concentrations induced G1 phase cell cycle arrest in K562 cells. Antimicrobial activity against Gram-positive, Gram-negative bacteria and fungal cells, and toxicity to brine shrimp Artemia sauna, were evaluated. There was no antibacterial activity. The best antifungal activity was exhibited against Saccharomyces cerevisiae by dimers linked with trithiolane ring, indicating a selective activity of investigated compounds.

AB  - Background: The aim of this research was to determine the intensity and mechanisms of the cytotoxic actions of five extracts isolated from the endemic plant species Helichrysum zivojinii Cernjavski & Soska (family Asteraceae) against specific cancer cell lines. In order to evaluate the sensitivity of normal immunocompetent cells implicated in the antitumor immune response, the cytotoxicity of extracts was also tested against healthy peripheral blood mononuclear cells (PBMC). Methods: The aerial parts of the plants were air-dried, powdered, and successively extracted with solvents of increasing polarity to obtain hexane, dichloromethane, ethyl-acetate, n-butanol and methanol extracts. The cytotoxic activities of the extracts against human cervix adenocarcinoma HeLa, human melanoma Fem-x, human myelogenous leukemia K562, human breast adenocarcinoma MDA-MB-361 cells and PBMC were evaluated by the MTT test. The mode of HeLa cell death was investigated by morphological analysis. Changes in the cell cycle of HeLa cells treated with the extracts were analyzed by flow cytometry. The apoptotic mechanisms induced by the tested extracts were determined using specific caspase inhibitors. Results: The investigated Helichrysum zivojinii extracts exerted selective dose-dependent cytotoxic actions against selected cancer cell lines and healthy immunocompetent PBMC stimulated to proliferate, while the cytotoxic actions exerted on unstimulated PBMC were less pronounced. The tested extracts exhibited considerably stronger cytotoxic activities towards HeLa, Fem-x and K562 cells in comparison to resting and stimulated PBMC. It is worth noting that the cytotoxicity of the extracts was weaker against unstimulated PBMC in comparison to stimulated PBMC. Furthermore, each of the five extracts induced apoptosis in HeLa cells, through the activation of both intrinsic and extrinsic signaling pathways. Conclusion: Extracts obtained from the endemic plant Helichrysum zivojinii may represent an important source of novel potential antitumor agents due to their pronounced and selective cytotoxic actions towards malignant cells.

AB  - Helichrysum zivojinii Cernjavski & Soska is an endemic plant species that grows in the National Park Galicica in Macedonia. Five extracts were isolated as fractions from the aerial parts of the plant: a n-hexane extract (1), a dichloromethane extract (2), an ethyl-acetate extract (3), a n-butanol extract (4) and a methanol extract (5). A dose-dependent cytotoxic activity of the extracts on MDA-MB-231 and EA.hy926 cells was observed. Extracts exhibited more pronounced cytotoxic actions on MDA-MB-231 cells than on EA.hy926 cells. The n-hexane extract (1), at a non-toxic concentration, exhibited an inhibitory effect on the migration as well the invasiveness of MDA-MB-231 cells. The dichloromethane extract (2), at a non-toxic concentration, demonstrated inhibition of MDA-MB-231 cells invasion. Each of the five extracts applied at non-toxic concentrations inhibited migration of EA.hy926 cells. The prominent inhibitory effect of the n-hexane extract on EA.hy926 cells migration was associated with a notable anti-angiogenic action of this extract. The other four tested extracts demonstrated mild anti-angiogenic activity. Our data highlight the prominent anticancer potential of n-hexane (1) and dichloromethane (2) extracts, which could be attributed to their very pronounced and selective cytotoxic activities as well as their anti-invasive and anti-angiogenic properties.

AB  - With the aim to evaluate the selectivity in the antitumor action, the cytotoxic activity of chamomile and marigold tea was tested against various malignant cell lines and against healthy immunocompetent peripheral blood mononuclear cells (PBMC). Chemical profiles of chamomile and marigold infusions and decoctions were analyzed by liquid chromatography/mass spectrometry; their total phenolic content and radical scavenging activity were determined, too. Results from present research demonstrate that chamomile and marigold tea exert selective dose-dependent cytotoxic action against target cancer cells. It is noteworthy that cytotoxicity of tea prepared from Calendula officinalis is remarkably higher in comparison to that from Matricaria recutita tea. The cytotoxic effect of chamomile tea is very weak to healthy PBMC, while the effect of marigold tea on PBMC is more pronounced. Marigold tea exerts highly selective antitumor effect especially to melanoma Fem-x cells in comparison to the action to normal healthy PBMC. Chemical analyses show that dominant phenolic compounds in examined infusions and decoctions are flavonoid glycosides and hydroxycinnamic acid derivatives. There are no considerable differences in total phenolic content and antioxidant activity between examined infusions. Antitumor potential of chamomile and marigold tea should be further investigated.

AB  - Six novel gold(III) complexes containing O,O'-dialkyl-(S,S)-ethylenediamine-N,N'-di-2-(3-cyclohexyl)propanoate ([AuCl2{(S,S)-R(2)eddch}]PF6, R = Me, Et, n-Pr, n-Bu, i-Bu, i-Am; 1-6, respectively) were synthesized and characterized by elemental analysis, UV/Visible, IR and NMR spectroscopy, mass spectrometry and differential pulse voltammetry. Density functional theory (DFT) calculations confirmed that diastereoisomer with the N,N' atoms configured (S,S) was the most stable. In vitro antiproliferative activity was determined against human cervix adenocarcinoma HeLa and human myelogenous leukemia K562 tumor cell lines, as well as against rested and stimulated normal immunocompetent human peripheral blood mononuclear cells (PBMC) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Complex 6 expressed the highest activity against K562 cells (IC50 = 3.8 +/- 0.5 mu M). Apoptosis, seen as condensation of HeLa cell nuclei was the mode of cell death induced by complexes 2-6. Complexes 3-6 induced death of K562 cells inhibiting cell entry in mitosis.

In vitro antiproliferative activity was determined against human cervix adenocarcinoma HeLa and human myelogenous leukemia K562 tumor cell lines, as well as against rested and stimulated normal immunocompetent human peripheral blood mononuclear cells (PBMC) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Complex 6 expressed the highest activity against K562 cells (IC50 = 3.8 +/- 0.5 mu M). Apoptosis, seen as condensation of HeLa cell nuclei was the mode of cell death induced by complexes 2-6. Complexes 3-6 induced death of K562 cells inhibiting cell entry in mitosis.",

AB  - The reactions of 17 alpha-hydroxyprogesterone with Lawesson's reagent (LR) in toluene, CH2Cl2 and/or CCl4 gave, depending on the duration of the reaction, two diastereoisomeric androst-4-en-17-spiro-1,3,2-oxathiaphospholane-2-sulfide pairs 2a,b and 3a,b in approximately 7:3 ratio, differing in configuration at the phosphorus atom. A parallel analysis of heteronuclear 2D H-1-C-13 spectra (HSQC and HMBC) and homo-nuclear 2D spectra (NOESY) enabled complete H-1 and C-13 assignments of each isomer. Also, analysis of NOESY correlations provided evidence for the preferred conformation. X-ray analysis of 3a confirmed the structure and absolute configuration on phosphorus. A pathway for the formation of 1,3,2-oxathiaphospholane ring was proposed. Cytotoxic activity in vitro was tested against three tumor cell lines (human cervix carcinoma HeLa cells and two human breast carcinoma MDA-MB-361 and MDA-MB-453 cells). Compound 3a and mixture 3a,b showed a moderate activity against HeLa and MDA-MB-453 cell lines while against MDA-MB-361 cell line all tested compounds exerted very weak cytotoxic effect. Antimicrobial activity against Gram-positive, Gram-negative bacteria and fungal cells, toxicity to brine shrimp Artemia sauna, were evaluated. All tested compounds showed strong antifungal activity.

AB  - It was demonstrated that mixed steroidal tetraoxanes inhibit cancer cell proliferation at micromolar level through an apoptotic mechanism. It will be interesting to see if these compounds may possibly induce oxidative stress, which could lead to induction of apoptosis in tumour cells. As tumour cells contain more iron than other normal tissues it is reasonable to suggest that tetraoxanes could react with iron, generating alkoxy radicals or even highly reactive hydroxyl radicals in a Fenton-like reaction. To gain further insight into the mechanism of cell death induced by tetraoxane endoperoxides, we tested production of reactive oxygen species (ROS) and level of activation of caspase 3 in tumour cells treated with several newly synthesized tetraoxanes.

AB  - Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different cancer cell lines-human cervix adenocarcinoma HeLa, human breast adenocarcinoma MDA-MB-361, and human breast carcinoma MDA-MB-453 and normal human peripheral blood mononuclear cells (PBMCs). Qualitative and quantitative compositions of wine polyphenolic extracts obtained by fractional vacuum distillation of corresponding wines were determined using spectrophotometric methods and high-performance liquid chromatography with diode array detection and liquid chromatography with electrospray ionization-time of flight mass spectrometry analysis. It was demonstrated that wine polyphenolic extracts and resveratrol exerted higher cytotoxic activity against HeLa and MDA-MB-453 cells in comparison to MDA-MB-361 cells and unstimulated and stimulated PBMCs. Furthermore, white wine polyphenolic extract exhibited a significantly higher antiproliferative action on cancer cell lines than red wine extract. The presence of condensed or fragmented nuclei in HeLa cells, pretreated with extract of white wine and stained with a mixture of acridine orange and ethidium bromide, pointed to the morphological signs of apoptosis. In addition, HeLa cells in late stages of apoptosis or secondary necrosis were also observed. Results from our study suggest that polyphenolic extracts from red and white wine may have anticarcinogenic potential.

AB  - An alignment-free 3D QSAR study on antiproliferative activity of the thirty-three 1,2,4,5-tetraoxane derivatives toward two human dedifferentiated cell lines was reported. GRIND methodology, where descriptors are derived from GRID molecular interaction fields (MIF), were used It was found that pharmacophoric pattern attributed to the most potent derivatives Include amido NH of the primary or secondary amide, and the acetoxy fragments at positions 7 and 12 of steroid core which are, along with the tetraoxane ring, common for all studied compounds. Independently, simple multiple regression model obtained by using the whole-molecular properties, confirmed that the hydrophobicity and the H-bond donor properties are the main parameters influencing potency of compounds toward human cervix carcinoma (HeLa) and human malignant melanoma (FemX) cell lines Corollary, similar structural motifs are found to be Important for the potency toward both examined cell lines.

AB  - Nine alkyl(aryl)thio derivatives of the marine sesquiterpene quinone avarone were synthesized by nucleophilic addition of thiols or thiophenol to avarone. In most cases only one regioisomer was obtained. Their cytotoxic activities, brine shrimp lethality and antibacterial activity were evaluated, as well as those of some previously synthesized avarone derivatives. Anti-HIV activity of two derivatives was tested. Electrochemical properties were determined for all the derivatives in Order to obtain more accurate information on structure-activity relationships. Most derivatives showed cytotoxic activity against tumor cell lines, with IC50 values less than 10 mu M for some of them, in particular those with electron-donating substituents. The most active Compound was 4'-(methylamino)avarone, with IC50 value of 2.4 mu M to melanoma Fem-X cells, and no cytotoxicity to normal lymphocytes.

AB  - In recent times interest has increased in the complementary medicine of cancer patients. Two herbal mixtures were prepared from 17 and 12 plants, respectively. The goal of this study was to examine the in vitro cytotoxic and cell cycle effects of the aqueous-ethanol extracts (Extract 1 and Extract 2) obtained by maceration of the mixtures. The two extracts investigated exhibited significant antiproliferative activity toward two human breast cancer cell lines (MDA-MB-361 and MDA-MB-453) and a human cervix carcinoma cell line (HeLa) with 50% inhibitory concentration (IC(50)) values ranging from 9.92 to 17.38 mu L/mL. The extracts did not exert any significant cytotoxicity toward healthy human peripheral blood mononuclear cells. In vitro antitumor activites were accompanied by an important apoptotic fraction of all cell lines after treatment with the extracts. The amount of total phenols was similar in both extracts, whereas the concentration of total tannins was significantly higher in Extract 1. Extract 1 was also found to be a stronger free radical scavenger, with an IC(50) value of 13.4 mu g/mL. Both extracts contained rosmarinic acid, while ursolic acid was identified in Extract 2.

AB  - New R2eddip-type esters (R = cyclopentyl, L3·2HCl 1.5H2O; cyclohexyl, L4·2HCl·H2O) and corresponding palladium(II) complexes, [PdCl2L3] (3) and [PdCl2L4]·H2O (4), as well as [PdCl2L2] (2; L2 diisobutyl ester of eddip) were synthesized and characterized by IR, 1H and 13C NMR spectroscopies and elemental analysis. The crystal structure of L3·2HCl·2CHCl3 was resolved and is given herein. The NMR spectroscopy confirmed the presence of two isomers (from three possible) for each palladium(II) complex. DFT calculations support the formation of two diastereoisomers. In addition, antitumoral investigations were performed and these investigations also included the diisopropyl ester of eddip (L1) and corresponding palladium(II) complex, [PdCl2L1] (1). In vitro antiproliferative activity was determined against several tumor cell lines HeLa, Fem-x, K562 and rested and stimulated normal immunocompetent cells (human peripheral blood mononuclear cells -PBMCs) using MTT test.

AB  - In this study we investigated the antiproliferative activity of six mixed steroidal tetraoxanes against various tumor cell lines, the toxicity against normal peripheral blood mononuclear cells (PBMC), and the mode of HeLa cell death induced by these compounds. Investigated tetraoxanes exerted a dose dependent antiproliferative action at micromolar concentrations toward target tumor cell lines. Treatment of HeLa cells for 24 h with all tetraoxanes induced apoptosis, as confirmed by morphological analysis and by the appearance of a typical ladder pattern in the DNA fragmentation assay.

AB  - Dehydroxylated MCM-41 and SBA-15 surfaces were modified by the grafting of two different titanocene complexes ([Ti(Tη5-C5H 4Me)2Cl2] and [Ti(Me2Si(η 5-C5Me4) (η5-C5H 4)}Cl2]) to give new materials, which have been characterized by powder X-ray diffraction, X-ray fluorescence, nitrogen gas sorption, MAS-NMR spectroscopy, thermogravimetry, SEM, and TEM. The toxicity of the resulting materials toward human adenocarcinoma HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x, and normal immunocompetent cells, such as peripheral blood mononuclear cells PBMC has been studied. Estimation of the number of particles per gram of material led to the calculation of O 50 values for these samples, which is the number of particles required to inhibit normal cell growth by 50%. In addition, M50 values (quantity of material needed to inhibit normal cell growth by 50%) of the studied surfaces is also reported. Nonfunctionalized MCM-41 and SBA-15 did not show notable antiproliferative activity, whereas functionalization of these materials with different titanocene based anticancer drugs led to very promising antitumoral activity. The best Q50 values correspond to titanocene functionalized MCM-41 surfaces (MCM-41/[Ti(η5C5H 4Me)2Cl2] (1) and MCM-41/[TiIMe 2Si(Tf-C5Me4)(Tf-C5H 4)(Cl2] (2)) with Q50 values between 3.8 ± 0.6 x 108 and 24.5 ±3.0 x 108 particles. Titanocene functionalized SBA-15 surfaces (SBA-15/[Ti(η5-C 5H4Me)2Cl2] (3) and SBA-15/[Ti{Me2Si(η5-C5Me 4)(η5C5H4)}Cl2] (4)) gave higher Q50 values, showing lower activity from 73.2 ± 9.9 x 108 to 362±7×l08 particles. The best response of the studied materials in terms of M50 values was observed against Fem-x (309 ± 42 g for 4) and K562 (338±18 g for 2), whereas moderate activities were observed in HeLa cells (from 508±63g of 2 to 912 ± 10g of 1). In addition, the analyzed surfaces presented only marginal activity against unstimulated and stimulated PBMC, showing a slight selectivity on human cancer cells.

The toxicity of the resulting materials toward human adenocarcinoma HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x, and normal immunocompetent cells, such as peripheral blood mononuclear cells PBMC has been studied. Estimation of the number of particles per gram of material led to the calculation of O 50 values for these samples, which is the number of particles required to inhibit normal cell growth by 50%. In addition, M50 values (quantity of material needed to inhibit normal cell growth by 50%) of the studied surfaces is also reported.

AB  - The antiproliferative activity of previously synthesized (Z)-cholest-4-en-6-one oxime (1), (E)-cholest-4-en-6-one oxime (2), 7-aza-B-homocholest-4-en-6-one (3) and 6-aza-B-homocholest-4-en-7-one (4) and newly synthesized 6-thioxo-7-aza-B-homocholest-4-ene (5) and 6-aza-7-thioxo-B-homocholest-4-ene (6) was tested for their possible effects against two human tumor cell lines, cervical carcinoma (HeLa) and chronic myelogenous leukemia (K-562). Compounds 1-6, exerted a dose-dependent antiproliferative effect toward cell lines used in experimental design, showing high selectivity in their action for tumor cells in comparison to normal immunocompetent cells (non-stimulated PBMC and PHA-stimulated PBMC). Compounds 2, 3 and 4 exhibited a very high but selective antitumor activity, by inducing apoptosis in sensitive, for that purpose targeted tumor cell line (HeLa cells). Low toxic effect upon both non-stimulated, and PHA stimulated PBMCs from control, healthy volunteers, has been detected for compounds 1, 2, 3 and 4. The possible reasons for profound differences in the effects of this spectrum of steroidal compounds between tumor cell lines and normal stimulated and non-stimulated PBMCs are discussed. The molecular mechanisms for apoptotic events in HeLa cell line are suggested. The guidelines for further research are underlined.
