Aromatase inhibitory and cytotoxic activities were determined for apigenin, luteolin and the new diterpene named scutebarbalactone VN, which were obtained by bioassay-guided fractionation and isolation from the methanol extract of the Vietnamese medicinal plant Banchi-lien (Scutellaria barbata D. Don). In the aromatase inhibition assay, an IC50 value of 3.36 mM was found for scutebarbalactone VN, while IC50  values of 7.2 mM and 7.95 mM were found for the positive controls aminoglutethimide and b-estradiol, respectively. In the cytotoxicity  assays using a panel of human cancer cell lines, scutebarbalactone VN showed promising anticancer activity with IC50  ranging from 2.15 to 8.3 mM compared with those of the positive control ellipticine ranging from 1.0 to 2.1 mM. Apigenin and luteolin were found to be inactive  in both assays.

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.

A series of novel structurally simple analogues based on nitidine was designed and synthesized in search of potent anticancer agents. The antitumor activity against human cancer cell lines (HepG2, A549, NCI-H460, and CNE1) was performed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay in vitro. The results showed that some of them had good anticancer activities, especially derivatives with a [(dimethylamino)ethyl]amino side chain in the C-6 position. Planar conjugated compounds 15a, 15b, and 15c, with IC50 values of 1.20 μM, 1.87 μM, and 1.19 μM against CNE1 cells, respectively, were more active than nitidine chloride. Compound 15b and compound 15c with IC50 values of 1.19 μM and 1.37 μM against HepG2 cells and A549 cells demonstrated superior activities to nitidine. Besides, compound 5e which had a phenanthridinone core displayed extraordinary cytotoxicity against all test cells, particularly against CNE1 cells with the IC50 value of 1.13 μM.

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.

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.

On the basis of the ‘one strain, many compounds’ (OSMAC) strategy, chemical investigation of the marine-derived fungus Trichothecium roseum resulted in the isolation of trichomide cyclodepsipeptides (compounds 1–4) from PDB medium, and destruxin cyclodepsipeptides (compounds 5–7) and cyclonerodiol sesquiterpenes (compounds 8–10) from rice medium. The structures and absolute configurations of novel (compounds 1, 8, and 9) and known compounds were elucidated by extensive spectroscopic analyses, X-ray crystallographic analysis, and ECD calculations. All isolated compounds were evaluated for cytotoxic, nematicidal, and antifungal activities, as well as brine shrimp lethality. The novel compound 1 exhibited significant cytotoxic activities against the human cancer cell lines MCF-7, SW480, and HL-60, with IC50 values of 0.079, 0.107, and 0.149 μM, respectively. In addition, it also showed significant brine shrimp lethality, with an LD50 value of 0.48 μM, and moderate nematicidal activity against Heterodera avenae, with an LC50 value of 94.9 μg/mL. This study constitutes the first report on the cytotoxic and nematicidal potential of trichomide cyclodepsipeptides.
