A new method for separation and quantitative determination of isofiavone glucosides in rhizomes of Belamcanda chinensis (Iridaceae) by high performance liquid chromatography was elaborated. A reverse-phase system with a Spheri-5 RP-18 column using MeOH : HOAc : H₂O(24 : 5 : 71) as a mobile phase was developed. The isoflavonoids were detected at 268 ㎚ and the analysis was successfully carried out within 15 min.

Phytochemical investigation of the MeOH extract of the root barks of Cudrania tricuspidata Bureau (Moraceae), as guided by hepatoprotective activity in vitro, furnished four isoprenylated xanthones, cudratricusxanthone A (1), cudraxanthone L (2), cudratricusxanthone E (3), and macluraxanthone B (4). All of these compounds showed the significant hepatoprotective effect on tacrine-induced cytotoxicity in human liver-derived Hep G2 cells. Compounds 1, 2, and 4 also exhibited the significant hepatoprotective effect on nitrofurantoin-induced cytotoxicity in human liver-derived Hep G2 cells.

Background: To determine the potential value of serum tumor markers in predicting pCR (pathological complete response) during neoadjuvant chemotherapy. Materials and Methods: We retrospectively monitored the pro-, mid-, and post-neoadjuvant treatment serum tumor marker concentrations in patients with locally advanced breast cancer (stage II-III) who accepted pre-surgical chemotherapy or chemotherapy in combination with targeted therapy at Fudan University Shanghai Cancer Center between September 2011 and January 2014 and investigated the association of serum tumor marker levels with therapeutic effect. Core needle biopsy samples were assessed using immunohistochemistry (IHC) prior to neoadjuvant treatment to determine hormone receptor, human epidermal growth factor receptor 2(HER2), and proliferation index Ki67 values. In our study, therapeutic response was evaluated by pCR, defined as the disappearance of all invasive cancer cells from excised tissue (including primary lesion and axillary lymph nodes) after completion of chemotherapy. Analysis of variance of repeated measures and receiver operating characteristic (ROC) curves were employed for statistical analysis of the data. Results: A total of 348 patients were recruited in our study after excluding patients with incomplete clinical information. Of these, 106 patients were observed to have acquired pCR status after treatment completion, accounting for approximately 30.5% of study individuals. In addition, 147patients were determined to be Her-2 positive, among whom the pCR rate was 45.6% (69 patients). General linear model analysis (repeated measures analysis of variance) showed that the concentration of cancer antigen (CA) 15-3 increased after neoadjuvant chemotherapy in both pCR and non-pCR groups, and that there were significant differences between the two groups (P=0.008). The areas under the ROC curves (AUCs) of pre-, mid-, and post-treatment CA15-3 concentrations demonstrated low-level predictive value (AUC=0.594, 0.644, 0.621, respectively). No significant differences in carcinoembryonic antigen (CEA) or CA12-5 serum levels were observed between the pCR and non-pCR groups (P=0.196 and 0.693, respectively). No efficient AUC of CEA or CA12-5 concentrations were observed to predict patient response toward neoadjuvant treatment (both less than 0.7), nor were differences between the two groups observed at different time points. We then analyzed the Her-2 positive subset of our cohort. Significant differences in CEA concentrations were identified between the pCR and non-pCR groups (P=0.039), but not in CA15-3 or CA12-5 levels (p=0.092 and 0.89, respectively). None of the ROC curves showed underlying prognostic value, as the AUCs of these three markers were less than 0.7. The ROC-AUCs for the CA12-5 concentrations of inter-and post-neoadjuvant chemotherapy in the estrogen receptor negative HER2 positive subgroup were 0.735 and 0.767, respectively. However, the specificity and sensitivity values were at odds with each other which meant that improving either the sensitivity or specificity would impair the efficiency of the other. Conclusions: Serum tumor markers CA15-3, CA12-5, and CEA might have little clinical significance in predicting neoadjuvant treatment response in locally advanced breast cancer.

Two new quinones, 1-hydroxy-5-pentyl-anthraquinone (1) and 4-(5-hydroxy-1,4-dioxo-1,4-dihydronaphthalen- 2-ylamino)-butyric acid methyl ester (2), together with two known quinones, 5-hydroxy-2-(2-hydroxy- ethylamino)-(1,4) naphthoquinone (3) and juglone (4) were isolated from the roots of Juglans mandshurica (Juglandaceae). Their structures were elucidated on the basis of spectral data. Compound 3 was isolated from the Juglans genus for the first time. Compounds 1–4 exhibited significant cytotoxicity towards cultured MDA-MB231, HepG2 and SNU638 cells with IC50 values ranging from 4.46 to 88.47 μM.

The present study was designed to isolate and characterize novel chemical constituents of the stem bark of Juglans mandshurica Maxim. (Juglandaceae).The chemical constituents were isolated and purified by various chromatographic techniques. The structures of the compounds were elucidated on the basis of spectral data (1D and 2D NMR, HR-ESI-MS, CD, UV, and IR) and by the comparisons of spectroscopic data with the reported values in the literatures. Two long chain polyunsaturated fatty acids (1 and 2) were obtained and identified as (S)-(8E, 10E)-12-hydroxy-7-oxo-8, 10-octadecadienoic acid (1) and (S)-(8E, 10E)-12-hydroxy-7-oxo-8,10-octadecadienoic acid methyl ester (2). To the best of our knowledge, this is the first report on the isolation and structural elucidation of the two new conjugated ketonic fatty acids from this genus.

Two new (1 and 3) and two known diarylheptanoids(2 and 4), along with two tetralones (5 and 6), onenaphthoquinone (7), four phenylpropanoids (8–11), andone phenol (12) were isolated from the leaves of Juglansmandshurica. Their structures were elucidated on the basisof spectral and chemical data. Compounds 2 and 10 arefirstly isolated from this plant and 8 and 12 were isolatedfrom the Juglans genus for the first time. Among thesecompounds, only 7 exhibited moderate cytotoxicitiesagainst cultured MGC-803, A549, K562, and HeLa tumorcell lines with IC50 values of 25.90, 28.60, 39.06,44.90 lM, respectively.
