Abstract

From the aerial parts of Hypericum polyanthemum Klotzsch ex Reichardt (Guttiferae), three chromenes, 6-isobutyryl-5,7-dimethoxy-2,2-dimethyl-benzopyran; 7-hydroxy-6-isobutyryl-5-methoxy-2,2-dimethyl-benzopyran and 5-hydroxy-6-isobutyryl-7-methoxy-2,2-dimethyl-benzopyran were isolated. Their structures were determined by NMR spectroscopic analyses.

HA14-1, a small molecule inhibitor of Bcl-2, bypasses chemoresistance in leukaemia cells.

We analyzed the biological activity of HA14-1, a small organic compound inhibitor of Bcl-2, against established leukaemia cell lines and blasts from acute myeloid leukaemia (AML) patients. HA14-1 had a potent killing activity against the leukaemia cell line that expressed endogenous or ectopic Bcl-2. This activity was mostly caspase-independent and was not altered by the expression of a multidrug-resistant phenotype. Moreover, HA14-1 efficiently induced cell death in a broad spectrum of AML blasts but not in normal peripheral blood lymphocytes. Thus, single-agent regimens using Bcl-2 inhibitors such as HA14-1 may be advantageous in overcoming some forms of chemoresistance in AML.

Mobilization and speciation of chromium in compost: a methodological approach.

An integral approach to study the mobility of chromium in compost is presented. The approach is based on batch pH dependence leaching tests and the analysis of the leachates for total chromium, chromium(VI) and complexes of chromium(III) with natural organic matter. As leachings are performed with no aggressive reagents (ultrapure water with added nitric acid or potassium hydroxide), the method can be considered a good approach to simulate natural scenarios. The analysis of leachates is complemented with the determination of total chromium and total Cr(VI) in the solid sample. Speciation analysis are done by high performance liquid chromatography with inductively coupled plasma mass spectrometry as detection technique; Cr(VI) is determined by ion chromatography, whereas Cr(III) complexes with natural organic matter by size exclusion chromatography. In the compost studied, Cr(VI) accounted for 6% of the total chromium in the solid, whereas no significant amounts of Cr(VI) were mobilized in the pH range studied (4-10). Chromium is mobilized as Cr(III) bound to organic matter, both to humic and fulvic acids, with an increasing contribution of humic acids at higher pHs.

Evolution of the fulvic acid fractions during co-composting of olive oil mill wastewater sludge and tree cuttings.

Fulvic acids (FAs) were isolated by a conventional procedure from two mixtures of the sludge residue obtained from olive oil mill wastewater (OMW) evaporated in open-air pond and tree cuttings (TC) at different stages of the co-composting process. The FAs were analyzed for elemental (C, H, N, S, O) and acidic functional group (carboxylic and phenolic) composition, and by ultraviolet/visible, Fourier transform infrared and fluorescence spectroscopies. At the initial stage of composting, FAs from the OMW sludge-TC mixtures were characterized by a prevalent aliphatic character, large contents of C, S-containing groups, proteinaceous materials and polysaccharide components, extended molecular heterogeneity, small O and acidic functional group contents, and small degrees of aromatic ring polycondensation, polymerization and humification. As composting proceeded, C, H and S contents, C/N ratio, and aliphaticity decreased, whereas N, O, COOH and phenolic OH contents, C/H and O/C ratios, and aromaticity increased. These results suggested that, with increasing the composting time, the chemical and structural properties of the FA components of the two OMW sludge-TC mixtures approached the characteristics typical of native soil FAs. Thus, co-composting of OMW sludge mixed with TC may represent a suitable treatment for enhancing the quality of organic matter in these materials when used as soil amendments.
