Annona Glabra

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.

ABSTRACTFrom leaves of Amesiodendron chinense (Mer.) Hu four lignans (+)-aptosimon (1), (+)-isolariciresinol (2), (-)-cleomiscosin A (3), and (-)-cleomiscosin C (3) were isolated. Their structures were determined by spectroscopic analysis including MS, 1D and 2D NMR as well as by comparison with reported data in literature. All compounds were evaluated for cytotoxic activities against five human cancer cell lines, KB, SK-LU-1, MCF-7, HepG-2, and SW-480. They showed weak cytotoxic activity on five tested human cancer cell lines with IC50 values ranging from 32.61 to 95.18 µg/ml.

Their structures were elucidated by 1D-, 2D-NMR spectroscopic analysis, HR-ESI-MS, and by comparing with the NMR data reported in the literature. The cytotoxic activities of the all compounds were evaluated on five human cancer cell lines, LU-1, HL-60, SK-Mel-2, HepG-2, and MCF-7. Compound 4 was found to exhibit significant cytotoxic activities on all tested human cancer cell lines with IC50 values ranging from 0.7 to 1.6 μg/mL.

One new schiartane- type triterpene, heteroclitalactone N (1), and four known compounds (2–5), seco-coccinic acid F, dihydroguaiaretic acid, schizanrin F, and kadsuralignan B were isolated from the stems of Kadsura heteroclita. Their structures were determined by the combination of spectroscopic and chemical methods, including 1D-, 2D-NMR, and CD spectra as well as by comparing with the NMR data reported in the literature. The cytotoxic activities of all isolated compounds were evaluated on three human cancer cell lines. Compound 3 exhibited moderate to weak cytotoxic activities on three human cancer cell lines, OVCAR, HT-29, and A-549, with IC50 values ranging from 16.2 to 36.4 μM.

Cytotoxic Compounds

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.

AbstractTwo new α-tetralonyl glucosides, (4S)-4,5,8-trihydroxy-α-tetralone-5-O-β-D-glucopyranosyl(1 → 6)-β-D-glucopyranoside (1) and (4S)-4,8-dihydroxy-α-tetralone-4-O-β-D-glucopyranosyl(1 → 6)-β-D-glucopyranoside (2), together with eight known compounds (3 – 10) were isolated from the green walnut husks of Juglans mandshurica. The structural characterization of all compounds was performed by spectroscopic analyses, including 1D and 2D NMR and HR-ESI-MS experiments. The isolated compounds were assayed for their cytotoxicity against two human cancer cell lines, A549 and HeLa. Four compounds (7 – 10) exhibited inhibitory effects against two human cancer cell lines with GI50 values between 1.3 and 5.8 µM.
