Papaver rhoeas plant is common in many regions worldwide and contributes to the landscape with its red flower. In the present study we first carried out morphological investigation by optical and scanning electron microscopy of the ovules within the ovary. After ovules’ isolation we prepared extracts to test possible cytotoxic activities on HL60 leukemia human cells and investigated the extracts using thin-layer chromatography (TLC) and gas-chromatography/mass spectrometry (GC-MS). P. rhoeas ovules showed an elongated, round shape and the presence of ordered sculptures on the ovule surface. The ovule extracts showed cytotoxic activity on HL60 human cells mainly found in some TLC-isolated spots. Compounds consisting of active spots were identified by GC-MS investigations. Our findings on the P. rhoeas ovule compounds open perspectives for further investigations of TLC-isolated spots on other human cancer cell lines.

A new ent-kaurane glycoside, annoglabasin H (1), and three known ent-kauranes, annoglabasin E (2), annoglabasin B (3), and 19-nor- ent-kaurent-4-ol-17-oic acid (4) were isolated from the fruits of Annona glabra. Their structures were determined by the combination of spectroscopic and chemical methods, including 1D- and 2D-NMR spectroscopy, as well as by comparison with the NMR data reported in the literature. The cytotoxic activities of these compounds were evaluated on four human cancer cell lines, LU-1, MCF-7, SK-Mel2, and KB. Compound 1 exhibited significant cytotoxic activity on all tested human cancer cell lines with IC50 values ranging from 3.7 to 4.6 μM.

A series of benzo [d] [1,3] azoles 2-substituted with benzyl- and allyl-sulfanyl groups were synthesized, and their cytotoxic activities were in vitro evaluated against a panel of six human cancer cell lines. The results showed that compounds BTA-1 and BMZ-2 have the best inhibitory effects, compound BMZ-2 being comparable in some cases with the reference drug tamoxifen and exhibiting a low cytotoxic effect against healthy cells. In silico molecular coupling studies at the tamoxifen binding site of ERα and GPER receptors revealed affinity and the possible mode of interaction of both compounds BTA-1 and BMZ-2.

Mature Seeds

The present study embraces phytochemical investigation of the essential oil extracted from the mature seeds of Trachyspermum ammi Linn for different constituents by subjecting the oil to gas chromatography-mass spectrometry (GC-MS) analysis. The identification of the constituents is based upon retention indices and by comparison of their mass spectral fragmentation patterns against the commercial library mass spectra (Wiley, Nist etc.). Ellagic acid (EA), which is a natural phenol antioxidant, has been isolated from methanol extract from the mature seeds of Trachyspermum ammi Linn. Also, Thymol (Thl), a naturally occurring phenolic compound, has been crystallized by the reported standard procedure from oil extracted from these mature seeds. Both these compounds have been evaluated for their possible anti-cancer effect against a selected panel of human cancer cell lines by means of sulforhodamine B assay.

AbstractSix new neo-clerodane diterpenoids (1–6), scutebatas X – Z, A1-C1, along with twelve known ones (7–18) were obtained via the phytochemical investigation of the aerial parts of Scutellaria barbata. Their structures were established by detailed spectroscopic analysis. The absolute configurations of 1 and 2, as the representative members of this type, were identified based on a circular dichroic exciton chirality method. Moreover, in vitro cytotoxicity of compounds 1–6 were evaluated against three human cancer cell lines (SGC-7901, MCF-7, and A-549) using the MTT method. Compound 6 showed cytotoxic activities against all the three cell lines with IC50 values of 17.9, 29.9, and 35.7 µM, respectively.

Murraya microphylla is the most closely related species to M. koenigii (Curry tree). Inspired by the traditional effects of M. koenigii, the antioxidant, anti-inflammatory, and cytotoxic activities of the essential oil and extracts of M. microphylla were evaluated for the first time. The light petroleum and chloroform extracts were found to be able to scavenge DPPH free radicals, inhibit linoleic acid peroxidation, and nitric oxide production, as well as to present cytotoxicity to the human cancer cell lines HepG2, Bel7402, Bel7403, and Hela, but the essential oil only showed moderate activities. Chemical analysis of the active extracts by LC-DAD-MSn indicated that carbazole alkaloids were the main constituents. GC-MS analysis of the essential oil resulted in identification of 91 constituents, representing 96.9% of the total oil, with ( E)-caryophyllene (18.4%) and terpinen-4-ol (12.6%) as the major constituents. These results demonstrate that M. microphylla has similar biological activities, as well as chemical constituents to M. koenigii, and the carbazole alkaloids were disclosed to be the main potential active components. A promising development as a flavor and potential therapeutic agent could thus be predicated for this plant.

Four new compounds, including two new polyketides, heterocornols M and N (1, 2), and a pair of epimers, heterocornols O and P (3, 4), were isolated from the fermentation broth of the marine sponge-derived fungus Pestalotiopsis heterocornis XWS03F09, together with three known compounds (5–7). The new chemical structures were established on the basis of a spectroscopic analysis, optical rotation, experimental and calculated electronic circular dichroism (ECD). All of the compounds (1–7) were evaluated for their cytotoxic activities, and heterocornols M-P (1–4) exhibited cytotoxicities against four human cancer cell lines with IC50 values of 20.4–94.2 μM.

The Plectranthus genus is commonly used in traditional medicine due to its potential to treat several illnesses, including bacterial infections and cancer. As such, aiming to screen the antibacterial and cytotoxic activities of extracts, sixteen selected Plectranthus species with medicinal potential were studied. In total, 31 extracts obtained from 16 Plectranthus spp. were tested for their antibacterial and anticancer properties. Well diffusion method was used for preliminary antibacterial screening. The minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) values of the five most active acetonic extracts (P. aliciae, P. japonicus, P. madagascariensis var. “Lynne”, P. stylesii, and P. strigosus) were determined. After preliminary toxicity evaluation on Artemia salina L., their cytotoxic properties were assessed on three human cancer cell lines (HCT116, MCF-7, and H460). These were also selected for mechanism of resistance studies (on NCI-H460/R and DLD1-TxR cells). An identified compound—parvifloron D—was tested in a pair of sensitive and MDR-Multidrug resistance cancer cells (NCI-H460 and NCI-H460/R) and in normal bronchial fibroblasts MRC-5. The chemical composition of the most active extract was studied through high performance liquid chromatography with a diode array detector (HPLC-DAD/UV) and liquid chromatography–mass spectrometry (LC–MS). Overall, P. strigosus acetonic extract showed the strongest antimicrobial and cytotoxic potential that could be explained by the presence of parvifloron D, a highly cytotoxic diterpene. This study provides valuable information on the use of the Plectranthus genus as a source of bioactive compounds, namely P. strigosus with the potential active ingredient the parvifloron D.

Methanol (MeOH), dichloromethane (DCM) and 80% MeOH extractions of fourteen medicinal plants of the families Solanaceae and Lamiaceae collected from different area of Iran were tested for their cytotoxic potential against MOLT-4 human cancer cell lines. Cytotoxicity of the tested plants indicated that 11 plants had one or two active extracts (IC50 ≤50): MeOH extracts of the shoots of Thymus trautvetteri, Solanum luteum and stems of Lycium shawii; DCM extracts of the shoots of Thymus kotschyanus, Salvia persepolitana, Ballota aucheri, Nepeta glomerulosa, Hyoscyamus tenuicaulis, Salvia lachnocalyx, Salvia sharifii as well as the stems of Salvia verticillata and the roots of Salvia multicaulis and S. lachnocalyx; 80% MeOH extracts of the shoots of T. trautvetteri, S. luteum and the stems of L. shawii. The DCM extract of the aerial parts of S. lachnocalyx as one of the most active species was subjected to the cytotoxic bioassay-guided fractionation and purification using combination of chromatography methods. The bioassay-guided fractionation of DCM extract of the shoots of S. lachnocalyx led to the isolation of two cytotoxic compounds: (2 Z,6 Z,10 Z,14 E)-geranylfarnesol (1), a novel natural product, and spathulenol (2). Both of the isolated compounds, especially 1 (IC50 range: 9.6 −20.2 μg/mL), showed good cytotoxic effects against 3 human cancer cell lines, MOLT-4, MCF-7 and HT-29.
