RESUMEN

BACKGROUND: The treatment options for newly diagnosed non-small-cell lung cancer (NSCLC) patients with 1 to 3 synchronous brain metastases (BM) remain controversial. The current study aimed to comprehensively analyze the characteristics, local treatment paradigms, and survival outcomes in these populations. PATIENTS AND METHODS: A total of 252 NSCLC patients initially diagnosed with 1 to 3 synchronous brain-only metastases were enrolled onto this study. Local therapy (LT) to primary lung tumors (PLT) and BM included surgery, radiotherapy, or both. Median overall survival (mOS) was measured among patients who received LT to both PLT and BM (all-LT group), patients who were treated with LT to either PLT or BM (part-LT group), and patients who did not receive any LT (non-LT group). RESULTS: The mOS for all-LT (n = 70), part-LT (n = 113), and non-LT (n = 69) groups was 33.2, 18.5, and 16.8 months, respectively (P = .002). The OS rates at 5 years for the all-LT, part-LT, and non-LT groups were 25.5%, 16.2%, and 0, respectively. Multivariable analysis revealed that all-LT versus non-LT, pretreatment Karnofsky performance status > 70, histology of adenocarcinoma, thoracic stage I-II, EGFR mutation, ALK positive, and second-line systemic therapies were independent prognostic factors for improved mOS. CONCLUSIONS: The current study showed that LT for both PLT and BM is associated with superior OS in appropriately selected NSCLC patients initially diagnosed with 1 to 3 synchronous BM. Prospective trials are urgently needed to confirm this finding.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Toxicodendron vernicifluum (Stokes) F.A. Barkley (syn. Rhus verniciflua or vernicifera Stokes, Anacardiaceae) (RVS), the lacquer tree, also known as sumac, has been used in China, Japan and South Korea for thousands of years as a highly durable coating material and a traditional herbal medicine, which contains medicinal ingredients with anti-tumor, anti-inflammatory, antiviral, and anti-rheumatic activities. AIM OF THIS REVIEW: This review intends to provide a comprehensive and critical appraisal of RVS, including its phytochemical data, botanical and pharmacological literature that support its therapeutic potential in treatment on human diseases, with emphasis on the isolation of natural occurring compounds and detailed pharmacological investigations. MATERIALS AND METHODS: Specific information of RVS was collected by using the key words "Toxicodendron vernicifluum", "Rhus verniciflua Stokes", "Rhus vernicifera Stokes" and "Lacquer tree" through published scientific materials (including PubMed, ScienceDirect, Wiley, ACS, CNKI, Scifinder, Springer, Web of Science, Google Scholar, and Baidu Scholar) and other literature sources. RESULTS: The major phytoconstituents, 175 of which are presented in this review, including flavonoids, urushiols, terpenes, phenolic acids and other types of compounds, of which flavonoids and urushiols are main components. The extracts and isolates purified from RVS showed a wide range of in vitro and in vivo pharmacological effects, such as anti-cancer, anti-oxidation, anti-inflammatory, antimicrobial, tyrosinase inhibition and so on. CONCLUSION: The modern pharmacological research of RVS mainly focus on the pharmacological effects of crude extract or active constituents, of which the flavonoids are widely studied. However, there are few reports on the relationship between pharmacological effects and their structures. And at present, there is still a lack of researches that are of both effective and in-depth. Meanwhile, there is little research on quality control. Apart from the wood and lacquer, other botanical parts also need to be explored further. In addition to phenolic compounds, the study on other types of components in T. vernicifluum would start more sparks for the discovery of new bioactive principles.

RESUMEN

Two new α-tetralonyl glucosides, (4S)-4,5,8-trihydroxy-α-tetralone-5-O-ß-D-glucopyranosyl(1 → 6)-ß-D-glucopyranoside (1: ) and (4S)-4,8-dihydroxy-α-tetralone-4-O-ß-D-glucopyranosyl(1 → 6)-ß-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.

RESUMEN

Zeasesquiterpene A-E (1-5), five new sesquiterpenes with two cyclohexanes, were isolated from the roots of Zea mays. Their structures were elucidated on the basis of 1D and 2D NMR spectral data and ECD analysis. A plausible biosynthetic pathway for the compounds (1-6) were hypothesized. All isolated compounds were screened for cytotoxicities against five human cancer cell lines (A549, MDA-MB-231, SK-Hep-1, SNU638 and HCT116) in vitro by MTT assay. Compound 4 showed potential cytotoxic activities against A549 (14.3 µΜ) and SNU638 (9.7 µΜ). By contrast, compound 1 exhibited moderate cytotoxicity to the four human cancer cell lines (A549, SK-Hep-1, SUN638 and HCT116), and the IC50 values are from 19.5 µΜ to 22.5 µΜ.
