OBJECTIVE: To investigate the anti-tumor activity of a novel cyclophosphamide derivate 4, 6-diphenyl cyclophosphamide (9b) on cultured SK-OV3 (human ovarian cancer cell line) and 143B (human osteosarcoma cell line) cells in vitro aid S180 (mouse sarcoma cell line) and B16 (murine melanoma cell line) solid tumors in vivo, and its possible anti-tumor mechanism. METHODS: The inhibitory effects of 9b on SK-OV3 and 143B cells proliferation were analyzed by MTT assay in vitro. The effect of 9b on cell cycle distribution and apoptosis were evaluated by flow cytometry. To evaluate the anti-tumor effect of 9b in vivo, mouse model bearing inoculated S180 and B16 tumor were established. RESULTS: MTT assay revealed that 9b obviously suppressed SK-OV3 and 143B cells growth and proliferation in a dose-dependent manner within the concentration ranging from 3.7 to 300 Limol·L-1 and in a time-dependent manner from 24 to 72 h. The IC50 value of 9b was (71.27±1.08) μmol·L-1 for SK-OV3 cells, and (98.50±0.82) μmol·L-1 for 143B cells respectively when incubation for 48 h. The results of flow cytometry indicated that after treated for 48 h with different concentration of 9b, the ratios of 143 B cells in the G0/G1 phase and SK-OV3 cells in the G0/G1 phase and G2/M phase were significantly increased compared with control group (P<0.05, P<0.01), the apoptosis rate had significantly increased (P<0.05, P<0.01). 9b (3, 10 and 30 mg·kg-1·d-1) could significantly reduce tumor weight in the S180 and B16 solid tumor mouse model in vivo. CONCLUSION: 9b showed significantly anti-tumor activity both in vivo and in vitro, of which the mechanism might be associated with the change of cell cycle distribution and induction of tumor cell apoptosis.

The methanol extract of Capparis zeylanica Linn. root was evaluated for its wound healing potential in two different types of wound models viz., incision and excision. Two dose levels (100, 200 mg/kg b.w.) of methanol extract of Capparis zeylanica root were tested by incision wound model. The 100 mg/kg produced mild wound healing activity whereas 200 mg/kg produced pronounced healing properties in the tested parameters, tensile strength and DNA content. Two concentrations, 1% and 2% were tested in the excision wound model. There was better healing property observed in 2% concentration when compared to povidone iodine ointment. It was confirmed by finding the parameters; percentage wound contraction, epithelisation time, collegen content and DNA content.

Secondary metabolites from plants play key roles in human medicine and chemical industries. Due to limited accumulation of secondary metabolites in plants and their important roles, characterization of key enzymes involved in biosynthetic pathway will enable metabolic engineering or synthetic biology to improve or produce the compounds in plants or microorganisms, which provides an alternative for production of these valuable compounds. Salvia miltiorrhiza, containing tanshinones and phenolic acids as its active compounds, has been widely used for the treatment of cardiovascular and cerebrovascular diseases. The biosynthetic analysis of secondary metabolites in S. miltiorrhiza has made great progress due to the successful genetic transformation system, simplified hairy roots system, and high-throughput sequencing. The cloned genes in S. miltiorrhiza had provided references for functional characterization of the post-modification steps involved in biosynthesis of tanshinones and phenolic acids, and further utilization of these steps in metabolic engineering. The strategies used in these studies could provide solid foundation for elucidation of biosynthetic pathways of diterpenoids and phenolic acids in other species. The present review systematically summarizes recent advances in biosynthetic pathway analysis of tanshinones and phenolic acids as well as synthetic biology and metabolic engineering applications of the rate-limiting genes involved in the secondary metabolism in S. miltiorrhiza. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

Objectives: The aim of this study was to elucidate the mechanism underlying the neuroprotective effects of the phosphatase and tensin homolog (PTEN) inhibitor, bisperoxovanadium-pic [bpV(pic)]. Methods: We determined the effects of bpV(pic) on amyloid-β-peptide-(25-35)-induced neurotoxicity, particularly intracellular reactive oxygen species (ROS) production and mitochondria-mediated apoptotic signaling, in a human neuroblastoma (SH-SY5Y) cell model. Results: We found that exposure of SH-SY5Y cells to amyloid β peptides (Aβ25-35) resulted in a significant reduction in cell viability accompanied by increased lactate dehydrogenase (LDH) release, elevated levels of intracellular ROS, and decreased superoxide dismutase (SOD) activities, all of which were reversed by co-treatment with bpV(pic). Moreover, bpV(pic) induced significant protection against Aβ25-35-induced apoptosis, and effectively suppressed mitochondria-dependent apoptotic signaling triggered by Aβ25-35. Discussion: Aβ peptides are thought to cause neurodegeneration in Alzheimer’s disease (AD), via the induction of free radical oxidative stress. Our results indicate that bpV(pic) provides protection against Aβ25-35-induced oxidative stress and neurotoxicity, suggesting that bpV(pic) could be a potential therapeutic candidate in the treatment of neurodegenerative diseases such as AD. © 2017 Informa UK Limited, trading as Taylor & Francis Group.

An efficient surfactant assisted ultrasonic extraction technology was employed for extracting shikonin from Arnebia euchroma and the extraction process was optimized. Based on single-factor experiments, a four-factor-three-levels experimental design has been developed. The optimum conditions were carried out at 35 °C for 35 min at a solid-to-liquid ratio of 1:12 upon the addition of 0.0004 g L-1 surfactant. Shikonin contents could be determined readily by high-performance liquid chromatography within 20 min. The mean yield of shikonin was 30.64 mg L-1. Moreover, the contact angle of the powder was 30.501° in methanol. The proposed method was reliable by repeatability, stability and recovery tests. The results indicated that addition of surfactant could significantly increase the extraction yield of shikonin.

Purpose: To explore associations of CYP2E1 and NAT2 polymorphisms with lung cancer susceptibility among Mongolian and Han populations in the Inner Mongolian region. Materials and Methods: CYP2E1 and NAT2 polymorphisms were detected by PCR-RFLP in 930 lung cancer patients and 1000 controls. Results: (1) Disequilibrium of the distribution of NAT2 polymorphism was found in lung cancer patients among Han and Mongolian populations (p=0.031). (2) Lung cancer risk was higher in individuals with c1, D allele of CYP2E1 RsaI/PstI, DraI polymorphisms and slow acetylation of NAT2 (c1 compared with c2, OR=1.382, 95%CI: 1.178- 1.587, p=0.003; D compared with C, OR=1.241, 95%CI: 1.053-1.419, P < 0.001; slow acetylation compared with rapid acetylation, OR=1.359, 95%CI:1.042-1.768, p=0.056) (3) Compared with c2/c2 and rapid acetylation, c1/c1 together with slow acetylation synergetically increased risk of lung cancer 2.83 fold. (4) Smokers with CYP2E1 c1/c1, DD, and NAT2 slow acetylation have 2.365, 1.916, 1.841 fold lung cancer risk than others with c2/c2, CC and NAT2 rapid acetylation, respectively. (5) Han smokers with NAT2 slow acetylation have 1.974 fold lung cancer risk than others with rapid acetylation. Conclusions: Disequilibrium distribution of NAT2 polymorphism was found in lung cancer patients among Han and Mongolian populations. Besides, Han smokers with NAT2 slow acetylation may have higher lung cancer risk compared with rapid acetylation couterparts. CYP2E1 c1/ c1, DD and NAT2 slow acetylation, especially combined with smoking, contributes to the development of lung cancer. CYP2E1 c1/c1 or DD genotype and NAT2 slow acetylation have strong synergistic action in increasing lung cancer risk.
