The screening of several Chinese medicinal herbs for nematocidal properties showed that the ethanol extract of Liriope muscari fibrous roots possessed significant nematocidal activity against the pine wood nematode (Bursaphelenchus xylophilus). From the ethanol extract, a new constituent (1,4-epoxy-cis-eudesm-6-O-β-D-glucopyranoside) and three known glycosides [1β,6α-dihydroxy-cis-eudesm-3-ene-6-O-β-D-glucopyranoside (liriopeoside A), 1β,6β-dihydroxy-cis-eudesm-3-ene-6-O-β-D-glucopyranoside, and 1α,6β-dihydroxy-5,10-bis-epi-eudesm-4(15)-ene-6-O-β D-glucopyranoside] were isolated by bioassay-guided fractionation. The structures were elucidated by 1D and 2D NMR and MS techniques. 1,4-Epoxy-cis-eudesm-6-O-β-D-glucopyranoside possessed moderate nemato-cidal activity against B. xylophilus with a LC(50 )value of 339.76 μg/mL, while liriopeoside A (LC(50) = 82.84 μg/mL) and 1β,6β-dihydroxy-cis-eudesm-3-ene-6-O-β-D-glucopyranoside (LC(50) = 153.39 μg/mL) also exhibited nematocidal activity against B. xylophilus. The crude extract of L. muscari fibrous roots exhibited nematocidal activity against the pine wood nematode with a LC(50) value of 182.56 μg/mL.

Antimicrobial metabolites from the endophytic fungus Pichia guilliermondii isolated from Paris polyphylla var. yunnanensis

Three steroids and one nordammarane triterpenoid were isolated for the first time from the endophytic fungus Pichia guilliermondii Ppf9 derived from the medicinal plant Paris polyphylla var. yunnanensis. By means of physicochemical and spectrometric analysis, they were identified as ergosta-5,7,22-trienol (1), 5α,8α-epidioxyergosta-6,22-dien-3β-ol (2), ergosta-7,22-dien-3β,5α,6β-triol (3), and helvolic acid (4). Both micro-dilution-colorimetric and spore germination assays were employed to evaluate their antimicrobial activity. Among them, helvolic acid (4) exhibited the strongest antibacterial activity against all test bacteria, with MIC values ranging from 1.56 μg/mL to 50 μg/mL, and IC(50) values from 0.98 μg/mL to 33.19 μg/mL. It also showed strong inhibitory activity on the spore germination of Magnaporthe oryzae with an IC(50) value of 7.20 μg/mL. Among the three steroids, 5α,8α-epidioxyergosta-6,22-dien-3β-ol (2) exhibited relatively strong antimicrobial activity. The results suggest that the endophytic fungus Pichia guillermondii Ppf9 could be a candidate for producing helvolic acid, and the metabolites from this fungus could be potentially developed as antimicrobial agents in the future.

Cytotoxic Podophyllotoxin Type-Lignans from the Steam Bark of <em>Bursera fagaroides </em>var. <em>fagaroides</em>

The hydroalcoholic extract of the steam bark of B. fagaroides var. fagaroides displayed potent cytotoxic activity against four cancer cell lines, namely KB (ED₅₀ = 9.6 × 10^-2 μg/mL), PC-3 (ED₅₀ = 2.5 × 10^-1 μg/mL), MCF-7 (ED₅₀ = 6.6 μg/mL), and HF-6 (ED₅₀ = 7.1 × 10^-3 μg/mL).

Synthesis and Antitumor Activity of a New 7-Azaindole Derivative

We designed and synthesized a 7-azaindole derivative（TH1082）, which was characterized by 1^H NMR and 13^C-NMR. We investigated its antitumor effects on human melanoma A375 cells, human liver cancer SMMC cells and human breast cancer MCF-7 cells in vitro via 3-（4,5-dimethyldiazol-2-yl）-2,5-diphenyl-tetrazolium bromide （MTT） assay and also explored the mechanism of antiproliferation of them. The results show that TH1082 significantly inhibited the proliferation of these cells to different extent. The IC50 values for A375 cells, SMMC cells and MCF-7 cells were 25.38, 48.70 and 76.94 μg/mL at 24 h, respectively. To observe cell morphological changes, acridine orange/ethidium bromide（AO/EB） staining and Hoechest33342/Pl staining were carried out. These results indicate that TH1082 could induced the apoptosis of A375 cells. The apoptotic rates were （9.5±2.09）%, （18.9±2.25）% and （39.5±2.02）%（5, 10 and 20 μg/mL） for A375, SMMC and MCF-7 cell lines, respectively. Further, we determined the activities of caspase-3 and caspase-9 in A375 cells treated with TH1082 at different concentrations（0, 5, 10 and 20 μg/mL） or Z-VAD-FMK（20 μmol/L）, a pan-caspase inhibitor for 24 h. The results show that TH1082 activated caspase-3 and caspase-9, and the activation could be blocked by Z-VAD-FMK. Taken together, these findings indicate that TH 1082 could inhibit the proliferation ofA375 cells via activating caspase-3 and caspase-9.
