PM10 samples were collected at six sampling sites in city center of Tianjin from April 2008 to January 2009. The concentrations of 17 selected polycyclic aromatic hydrocarbons (PAHs) in PM10 were quantified. Spatial and seasonal variations of PAHs were characterized. The dominant PAHs in PM10 samples were fluoranthene, pyrene, benz[a] anthracene, phenanthrene, chrysene, benzo[b]fluoranthene, an...

In the title compound, [Fe(C(5)H(5))(C(31)H(24)N(3)O)], the pyrrolidine ring makes a dihedral angle of 86.3 (3)° with the mean plane [r.m.s deviation = 0.074 (2) Å] of the indeno-quinoxaline ring system. The central pyrrolidine ring adopts a twist conformation and the two cyclopentadienyl rings adopt an eclipsed conformation. In the crystal, mol-ecules are linked by weak C-H⋯N and C-H⋯π inter-a...

Dibenzopyracylene (indeno[l ,2,3-cdjfluoranthene) (4) is of theoretical interest due to its electron system, which is regarded as a perturbed [12]annulene [4]. 4 wras only accessible by a multistep synthesis starting from fluoranthene [5]. It was also isolated in traces from the tar formed by pyrolysis of several low molecular compounds [6]. According to the results [3, 7, 8] of the CO eliminat...

Oil spills are one of the environmental pollutions that commonly occur along coastal areas. Tar-balls products come from oil spill pollution. In this study, tar-ball pollution was monitored at 10 points coastline Marintaman Beach in Sipitang, Sabah, Malaysia. This research determined physical characteristics, composition, and concentration Polycyclic Aromatic Hydrocarbons (PAHs) tar-balls. The ...

Due to their system of annulated 6-5-5-6-membered rings, indenoindoles have sparked great interest for the design of ATP-competitive inhibitors of human CK2. In the present study, we prepared twenty-one indeno[1,2-b]indole derivatives, all of which were tested in vitro on human CK2. The indenoindolones 5a and 5b inhibited human CK2 with an IC50 of 0.17 and 0.61 µM, respectively. The indeno[1,2-...

A series of novel 11-Indeno[1,2-b]quinoxalin-11-one have been synthesized by condensation of Indeno[1,2-b]quinoxalin-11-one and primary amines. Their chemical structures were assigned by means of spectral analysis (FT-IR, H-NMR). Synthesized compounds were screened for in vitro antiviral activity against HIV -1 and -2 in MT-4 cells and Cytotoxicity was also investigated in mock-infected MT-4 ce...

Novel solid-emissive indeno[1,2-b]benzo[4,5-e]pyran-11-one-type fluorophores having non-planar structures with sterically hindered substituents (R = butyl, phenyl, and thienyl) have been designed and conveniently synthesized. The fluorescence quantum yields of in 1,4-dioxane were (Phi = 0.053) >> (Phi = 0.013) > (Phi = 0.003). On the other hand, the solid-state fluorescence quantum yields of th...

The in vitro effects of polycyclic aromatic hydrocarbons (PAHs) on haemocyte and haemolymphatic parameters of the Pacific oyster, Crassostrea gigas, were tested using field concentrations (10(-7) and 10(-9) mg mL(-1)) observed in the Marennes-Oleron Basin (Charente-Maritime, France) and high concentrations (10(-3) and 10(-5) mg mL(-1)) observed during oil spills. As a first step, the effects of...
