1.Hyperoside protects human primary melanocytes against H2O2-induced oxidative damage.
Yang B1, Yang Q2, Yang X1, Yan HB1, Lu QP3. Mol Med Rep. 2016 Apr 12. doi: 10.3892/mmr.2016.5107. [Epub ahead of print]
Cuscutae semen has been shown to have beneficial effects in the treatment of vitiligo, recorded in the Chinese Pharmacopoeia, whereas the effects of its constituent compounds remains to be elucidated. Using a tetrazolium bromide assay, the present study found that hyperoside (0.5‑200 µg/ml) significantly increased the viability of human melanocytes in a time‑ and dose‑dependent manner. The present study used a cell model of hydrogen peroxide (H2O2)‑induced oxidative damage to examine the effect of hyperoside on human primary melanocytes. The results demonstrated that hyperoside pretreatment for 2 h decreased cell apoptosis from 54.03±9.11 to 17.46±3.10% in the H2O2‑injured melanocytes. The levels of oxidative stress in the mitochondrial membrane potential of the melanocytes increased following hyperoside pretreatment. The mRNA and protein levels of B‑cell lymphoma‑2/Bcl‑2‑associated X protein and caspase 3 were regulated by hyperoside, and phosphoinositide 3‑kinase/AKT and mitogen‑activated protein kinase signaling were also mediated by hyperoside.
2.MicroRNA-22 is downregulated in clear cell renal cell carcinoma, and inhibits cell growth, migration and invasion by targeting PTEN.
Fan W1, Huang J1, Xiao H1, Liang Z2. Mol Med Rep. 2016 Apr 11. doi: 10.3892/mmr.2016.5101. [Epub ahead of print]
MicroRNA (miR)-22 has previously been reported to be frequently downregulated in certain types of cancer. The present study examined the expression and effects of miR-22 in renal cell carcinoma (RCC). The results indicated that miR‑22 was downregulated in tumor tissue from patients with RCC. In addition, lower miR‑22 expression levels were associated with histological grade, tumor stage and lymph node metas-tasis. Following transfection of RCC cells with miR‑22, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, cell migration, cell invasion and luciferase assays, and western blotting were conducted. The results demonstrated that miR‑22 was able to inhibit cell proliferation, migration and invasion in 786‑O and A498 cells. Furthermore, the results indicated that miR‑22 may directly target phosphatase and tensin homolog (PTEN) in RCC. In conclusion, the present study suggested that the miR-22/PTEN axis may be considered a novel therapeutic target in RCC.
3.Quantitative analysis of the hydration of lithium salts in water using multivariate curve resolution of near-infrared spectra.
Barba MI1, Larrechi MS2, Coronas A1. Anal Chim Acta. 2016 May 5;919:20-7. doi: 10.1016/j.aca.2016.03.022. Epub 2016 Mar 19.
The hydration process of lithium iodide, lithium bromide, lithium chloride and lithium nitrate in water was analyzed quantitatively by applying multivariate curve resolution alternating least squares (MCR-ALS) to their near infrared spectra recorded between 850 nm and 1100 nm. The experiments were carried out using solutions with a salt mass fraction between 0% and 72% for lithium bromide, between 0% and 67% for lithium nitrate and between 0% and 62% for lithium chloride and lithium iodide at 323.15 K, 333.15 K, 343.15 K and 353.15 K, respectively. Three factors were determined for lithium bromide and lithium iodide and two factors for the lithium chloride and lithium nitrate by singular value decomposition (SVD) of their spectral data matrices. These factors are associated with various chemical environments in which there are aqueous clusters containing the ions of the salts and non-coordinated water molecules. Spectra and concentration profiles of non-coordinated water and cluster aqueous were retrieved by MCR-ALS.
4.Synthesis of N-substituted phthalimides and their antifungal activity against Alternaria solani and Botrytis cinerea.
Pan L1, Li X2, Gong C3, Jin H2, Qin B4. Microb Pathog. 2016 Apr 12;95:186-192. doi: 10.1016/j.micpath.2016.04.012. [Epub ahead of print]
As organosulfur and organophosphorus agents, phaltane and phosmet are facing great challenges for the environmental contamination, mammalian toxicity and increasing resistance with long term use. It is efficient and meaningful to develop phthalimide-based alternatives with non-sulfur and non-phosphorus groups. A series of N-substituted phthalimides were synthesized and their antifungal activity against two disastrous phytopathogenic fungi, Alternaria solani and Botrytis cinerea was evaluated in vitro. Most of them showed significant antifungal activity against both of fungi, or either of them selectively. N-vinylphthalimide (4) and 8-[4-(phthalimide-2-yl) butyloxy] quinoline (13) were identified as the most promising candidates against B. cinerea and A. solani with the IC50 values of 7.92 μg/mL and 10.85 μg/mL respectively. The brief structure-activity relationships have revealed that vinyl, quinolyl, bromide alkyl and benzyl substitutions were appropriate substituents and coupling functional moieties indirectly with optimum alkyl chain was efficient to prepare phthalimides related fungicides.
