Advances in research on the effects of platelet activation in acute lung injury (Review).

Acute lung injury (ALI) is an acute hypoxic respiratory insufficiency or failure caused by various factors inside and outside the lungs. ALI is associated with high morbidity and a poor prognosis in hospitalized patients. The lungs serve as a reservoir for platelet precursor megakaryocytes and are closely associated with platelets.

Synthesis and biological evaluation of novel -(piperazin-1-yl)alkyl-1-dibenzo[,]carbazole derivatives of dehydroabietic acid as potential MEK inhibitors.

In this paper, a series of novel 1-dibenzo[,]carbazole derivatives of dehydroabietic acid bearing different -(piperazin-1-yl)alkyl side chains were designed, synthesised and evaluated for their anticancer activities against three human hepatocarcinoma cell lines (SMMC-7721, HepG2 and Hep3B). Among them, compound exhibited the most potent activity against three cancer cell lines with IC values of 1.39 ± 0.

Synthesis and biological evaluation of novel N-substituted 1H-dibenzo[a,c]carbazole derivatives of dehydroabietic acid as potential antimicrobial agents.

A series of new N-substituted 1H-dibenzo[a,c]carbazole derivatives were synthesized from dehydroabietic acid, and their structures were characterized by IR, (1)H NMR and HRMS spectral data. All compounds were evaluated for their antibacterial and antifungal activities against four bacteria (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas fluorescens) and three fungi (Candida albicans, Candida tropicalis and Aspergillus niger) by serial dilution technique. Some of the synthesized compounds displayed pronounced antimicrobial activity against tested strains with low MIC values ranging from 0.

Expression and significance of Wnt signaling components and their target genes in breast carcinoma.

The aim of this study was to investigate the expression of β-catenin, axin, cyclin D1 and c-myc, and their correlation with various clinicopathological factors of breast carcinoma. Using immunohistochemistry, the expression of axin, β-catenin, cyclin D1 and c-myc proteins was detected in 168 breast carcinomas and 40 normal breast tissue samples, as well as in 72 breast intraductal proliferative lesions. Correlations among the expression of these proteins with the clinicopathological factors of breast carcinomas were subsequently analyzed.

Furandiones from an endophytic Aspergillus terreus residing in Malus halliana.

Two new furandiones named asperterone B (1) and C (2) together with four known metabolites (3-6) were isolated from the liquid culture of the endophytic fungus Aspergillus terreus MHL-P22 residing in the fresh leaves of Malus halliana. The structures of the new compounds were elucidated by analysis of their MS, IR, 1D- and 2D-NMR spectra. 1 and 2 showed moderate cytotoxic activities against human colorectal carcinoma SW1116 cells with IC(50) values of 57.

N-(4-Bromo-phen-yl)-3,4,5-trimeth-oxy-benzamide.

In the title compound, C(16)H(16)BrNO(4), the dihedral angle between the two aromatic rings is 67.51 (25)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds involving the N-H and C=O groups of the amide function, leading to a chain along [-101].
