The cytotoxic effects of the essential oils obtained from the flowering aerial parts (APO) and ripe fruits (RFO) of Echinophora spinosa L. (Apiaceae) from central Italy toward human U937 promonocytoid cells were studied; the contribution of each of the major constituents to the whole cytotoxic activity of either APO or RFO was also characterized. The major components of APO were β-phellandrene (34.7%), myristicin (16.5%), p-cymene (16.3%), δ3-carene (12.6%), α-pinene (6.7%) and α-phellandrene (6.2%); those of RFO p-cymene (50.2%), myristicin (15.3%), α-pinene (15.1%) and α-phellandrene (8.1%). Both oils tested were toxic to U937 cells, but RFO was much more cytotoxic: indeed, the IC50 values calculated from the linear regression curves of RFO and APO were 14.5 ± 0.85 and 43.4 ± 2.81 μg/mL, respectively. α-Pinene and α-phellandrene were identified as the most toxically relevant constituents: however, they did not completely account for the toxic effects of genuine APO and RFO. Interestingly, we found that p-cymene, although per se devoid of toxicity within the tested range of concentrations, was capable of significantly sensitizing U937 cells to the cytotoxic activity of α-pinene and α-phellandrene, and that specific mixtures of these three terpenes were as toxic as genuine APO and RFO.

Inula aucheriana DC is a member of the family Asteraceae which is known to produce cytotoxic secondary metabolites noted as sesquiterpene lactones. In the present study, sesquiterpene lactones inuchinenolide B, 6-deoxychamissonolide (stevin) and 14-acetoxy-1β,5α,7αH-4β-hydroxy-guai-9(10),11(13)-dien-12,8α-olide were isolated from I. aucheriana. Inuchinenolide B and 14-acetoxy-1β,5α,7αH-4β-hydroxy-guai-9(10),11(13)-dien-12,8α-olide were further evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay to demonstrate cytotoxic activity with IC50 values of (56.6, 19.0), (39.0, 11.8), and (55.7, 15.3) μg/mL against HepG-2, MCF-7 and A-549 cells, respectively. The cytotoxic activity of the two evaluated sesquiterpene lactones partly explains the cytotoxic activity that was previously observed for the extracts of Inula aucheriana. The isolated compounds could be further investigated in cancer research studies.

The aim of this study was to evaluate the inhibitory activity of compounds isolated from the aerial parts of Hedyotis pilulifera (Pit.) T.N. Ninh toward selected cancer cell lines. The isolated compounds were identified by analyzing their nuclear magnetic resonance spectral data and physical properties, and comparison of these with reported data. The sulforhodamine B assay was used for the cytotoxic evaluation of isolates. Among twenty-one compounds isolated from H. pilulifera, compounds 2, 3, and 4 showed moderate inhibitory effect on MCF-7 with IC50 values of 63.5, 59.4, and 52.7 μg/mL, respectively, while the other compounds exhibited no effect (IC50 values > 100 μg/mL). Further investigation using HT29, LU-1, HL-60, KB, Hep G2, and SK-Mel2 cancer cell lines showed the moderate cytotoxic activity of compound 3 (IC50 values ranging from 51.7 to 78.3 μg/mL) to all cells, while compound 4 showed selective effect only against HL-60 cells (IC50 61.5 μg/mL). This is the first report of cytotoxic activity of pomolic acid 3β-acetate (3) toward all tested cancer cell lines, and also the first report of cytotoxicity of rotungenic acid (4) against LU-1, HL-60, KB, Hep G2, and SK-Mel2 cancer cell lines. The methanol extract of chaga mushroom { Inonotus obliquus (Ach. ex Pers.) Pilát} exhibited the strongest cytotoxic effects against HL-60 and LU-1 (32.2 and 38.0 μg/mL, respectively), and modest cytotoxic effects against SW480 (41.3 μg/mL), HepG2 (51.3 μg/mL), KB (57.0 μg/mL), and LNCaP (57.7 μg/mL). We conclude that compounds 3 and 4 from H. pilulifera may be useful in further investigation for anticancer agent discovery and chaga could be used as a natural anticancer remedy against promyelocytic leukemia and lung adenocarcinoma.

Culms and leaves of Cymbopogon citratus L. were collected from two regions of Phu Tho province (Thanh Son and Phu Ninh) and used as materials for essential oil extraction. Oils obtained were steam-distilled, analyzed for chemical composition and evaluated for cytotoxic activity against three different cancer cell lines. The GC/MS analysis showed that citral is the major content of the steam-distilled essential oils which was found in the range of 64.15-76.22%. Camphene was found only in culm oils of both regions but it was not detected in the leaf oils. Interestingly, the isomer forms of ocimene present at higher content in the culm oils than in the leaf oils whereas myrcene content in the leaf oils is higher than that in the culm oils. In a cytotoxicity test, four essential oils of culms and leaves of C. citratus from Thanh Son and Phu Ninh showed potent activity against A549 (human lung carcinoma) cell line with the IC50 values ranging from 4.01±0.39 to 6.3±0.54 µg/ml. The essential oils (culms and leaves) from Phu Ninh exhibited moderate effects on the Hela (human cervical adenocarcinoma) cells with the IC50 values of 19.43±1.16 and 42±2.41 µg/ml, respectively. However, they were inactive against the human hepatocellular carcinoma Hep3B cell line. The essential oils from Thanh Son exhibited potent cytotoxic activity against Hela and Hep3B cell lines with the IC50 values ranging from 1.18±0.26 to 8.91±0.32 µg/ml. The results indicated that the essential oils of C. citratus from Thanh Son, Phu Tho could be considered as a promising candidate for the natural sources of anticancer agents.

Abstract: A Lewis acid BF3•Et2O-mediated intramolecular cycloaddition reaction of mahanimbine (1) is described. Three cycloadducts, bicyclomahanimbine (2), cyclomahanimbine (3) and murrayazolinine (4) were obtained. The structural char-acterization of these compounds were determined by 1D and 2D NMR experiments. These compounds showed no cytotoxic activity against human MRC-5 cells (IC50 > 60 μg/mL). Compound 3 showed the highest inhibition cytotoxic effects against HeLa and HL-60 cancer cells with IC50 values of 10.0 and 28.7 μg/mL, respectively. This strategy opens a new approach for the synthesis of biologically significant cyclic monoterpenoid pyrano[3,2-a]carbazole alkaloids

This study aimed to investigate the susceptibility of Trypanosoma brucei to the Anthriscus nemorosa essential oils (EOs), isolated compounds from these oils, and artificial mixtures of the isolated compounds in their conventional and nanoencapsulated forms. The chemical composition of the essential oils from the aerial parts and roots of Anthriscus nemorosa, obtained from a wild population growing in central Italy, were analyzed by gas chromatography/mass spectrometry (GC/MS). In both cases, the predominant class of compounds was monoterpene hydrocarbons, which were more abundant in the EOs from the roots (81.5%) than the aerial parts (74.0%). The overall results of this work have shed light on the biological properties of A. nemorosa EO from aerial parts (EC50 = 1.17 μg/mL), farnesene (EC50 = 0.84 μg/mL), and artificial mixtures (Mix 3–5, EC50 in the range of 1.27 to 1.58 μg/mL) as relevant sources of antiprotozoal substances. Furthermore, the pool measurements of ADP (adenosine diphosphate) and NTPs (nucleoside triphosphates) in the cultivated bloodstream form of trypanosomes exposed to different concentrations of EOs showed a disturbed energy metabolism, as indicated by increased pools of ADP in comparison to ATP (adenosine triphosphate) and other NTPs. Ultimately, this study highlights the significant efficacy of A. nemorosa EO to develop long-lasting and effective antiprotozoal formulations, including nanoemulsions.

Genista species (family Leguminosae) show interesting biological properties. In this paper we describe the biological activity of the essential oils extracted from the aerial parts of G. sessilifolia DC. and G. tinctoria L. against M14 human melanoma cells, testing several biochemical parameters, such as cell vitality, cell membrane integrity and genomic DNA fragmentation. In addition, we report for the first time the study of the composition of the essential oil obtained from G. tinctoria. The most abundant components of the oil were carbonylic compounds such as ( E)-β-ionone (9.1%), dihydroactinidiolide (7.3%), nonanal (5.1%) and hexahydrofarnesylacetone (4.3%). The essential oils from aerial parts of both G. sessilifolia and G. tinctoria showed interesting potential anticancer activity, suggesting the presence of active compounds.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

The essential oils from Foeniculum vulgare commercial aerial parts and fruits were isolated by hydrodistillation, with different distillation times (30 min, 1 h, 2 h and 3 h), and analyzed by GC and GC-MS. The antioxidant ability was estimated using four distinct methods. Antibacterial activity was determined by the agar diffusion method. Remarkable differences, and worrying from the quality and safety point of view, were detected in the essential oils. trans-Anethole (31-36%), α-pinene (14-20%) and limonene (11-13%) were the main components of the essentials oil isolated from F. vulgare dried aerial parts, whereas methyl chavicol (= estragole) (79-88%) was dominant in the fruit oils. With the DPPH method the plant oils showed better antioxidant activity than the fruits oils. With the TBARS method and at higher concentrations, fennel essential oils showed a pro-oxidant activity. None of the oils showed a hydroxyl radical scavenging capacity >50%, but they showed an ability to inhibit 5-lipoxygenase. The essential oils showed a very low antimicrobial activity. In general, the essential oils isolated during 2 h were as effective, from the biological activity point of view, as those isolated during 3 h.
