Mutagenic activity of nine nitro derivatives of benzanthrone, namely 1-nitro-, 2-nitro-, 3-nitro-, 9-nitro-, 11-nitro-, 1,9-dinitro-, 3,9-dinitro-, 3,11-dinitro- and 3,9,11-trinitrobenzanthrone were tested with Salmonella strains TA98, TA100, YG1021 and YG1024 in both the presence and absence of an S9 mix. Each compound exhibited mutagenic activity with all the strains. Among these nine isomers...

OBJECTIVE Inflammatory processes and foam cell formation are key determinants in the initiation and progression of atherosclerosis. Electrophilic nitro-fatty acids, byproducts of nitric oxide- and nitrite-dependent redox reactions of unsaturated fatty acids, exhibit antiinflammatory signaling actions in inflammatory and vascular cell model systems. The in vivo action of nitro-fatty acids in chr...

ZnO and ZrO2 photo catalysts were synthesized by sol-gel auto combustion method. The products were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and ZrO2 was obtained 44 and 51 nm, respectively. Also, photo catalytic degrada...

Tiofenóis reagem com nitro olefinas em meio aquoso dando os correspondentes nitro-sulfetos em 58 95 % de rendimento. Este processo leva à formação, predominante, de produtos anti. Para o caso da nitro olefina cíclica 1-nitro-ciclo-hexeno é observada unicamente a formação de cis-1nitro-2-(tio-fenil)-ciclo-hexano. Esta metodologia é interessante porque utiliza-se água como solvente levando à mini...

8-Nitro-cGMP was recently discovered as a second messenger of nitric oxide. We describe here the synthesis and properties of DMACM-modified 8-nitro-cGMP for photochemical uncaging. Owing to the limited photostability of 8-nitro-cGMP care must be taken, but the photorelease of the intact product was readily feasible. Unexpectedly, 8-nitro-cGMP decays under formation of 8-nitrosoguanine when irra...

In the title compound, C(5)H(8)N(3) (+)·C(7)H(4)NO(4) (-)·C(7)H(5)NO(4), the non-H atoms of the 3,4-diamino-pyridinium cation are coplanar, with a maximum deviation of 0.022 (1) Å. The carboxyl-ate and nitro groups of the 4-nitro-benzoate anion are twisted out of the attached ring planes by dihedral angles of 15.89 (8) and 10.20 (8)°, respectively. In the 4-nitro-benzoic acid mol-ecule, the car...
