Nitrospira are a diverse group of nitrite-oxidizing bacteria and among the environmentally most widespread nitrifiers. However, they remain scarcely studied and mostly uncultured. Based on genomic and experimental data from Nitrospira moscoviensis representing the ubiquitous Nitrospira lineage II, we identified ecophysiological traits that contribute to the ecological success of Nitrospira. Une...

The asymmetric synthesis of the orthogonally funtionalised compounds tert-butyl 2-N-benzyl-N-alpha-methylbenzylamino-5-methoxycarbonylmethylcyclopentane- 1-carboxylate and methyl 2-N-benzyl-N-alpha-methylbenzylamino-5-carboxymethylcyclo- pentane-1-carboxylate by a domino reaction of tert-butyl methyl (E,E)-octa-2,6- diendioate with lithium N-alpha-methylbenzyl-N-benzylamide initiated by a Micha...

The first metal complexes comprising amidino-guanidinate ligands have been prepared and structurally characterized, namely bis-[μ-N,N',N'',N'''-tetraisopropyl-1-(1-butyl-amidinato)guanidinato-κ3N1,N2:N2]bis-[(tetra-hydro-furan)lithium], [Li2(C18H37N4)2(C4H8O)2], (2), and [bis-(tetra-hydro-furan)-lithium]-di-μ-chlorido-{(N,N'-di-cyclo-hexyl-1-butyl-amidinato-κ2N1,N2)[N,N',N'',N'''-tetra-cyclo-he...

1. Urethane is metabolized in the rat, rabbit and man by a process of N-hydroxylation. This occurs to a smaller extent when methyl, n-propyl and n-butyl carbamates are administered to the rat and rabbit. 2. Other metabolites which have been detected in urine of animals dosed with urethane and N-hydroxyurethane are ethylmercapturic acid, ethylmercapturic acid sulphoxide and N-acetyl-S-carbethoxy...

The effect of N-acetyl-L-cysteine on interleukin-1beta-induced nitric oxide synthase expression was studied in rat vascular smooth muscle cells to determine if the reduction/oxidation state would modulate cytokine-induced changes. Interleukin-1beta induced the production of nitrite, a stable metabolite of nitric oxide in a time- and dose-dependent manner. Cytokine-induced nitrite production was...

The water-soluble gold(III) complex [Au(III)(butyl-C^N)biguanide]Cl (butyl-HC^N = 2-(4-n-butylphenyl)pyridine, BCN) displays cytotoxicity through S-phase cell cycle arrest and endoplasmic reticulum (ER) damage in HeLa cells, and shows a promising anti-angiogenic effect at sub-cytotoxic concentrations.

In the mol-ecule of the title compund [systematic name: N-butyl-N-ethyl-2,5,6-trimethyl-7-(2,4,6-trimethyl-phen-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine], C(24)H(34)N(4), the pyrrolopy-rimidine ring system is nearly planar, its five- and six-membered rings forming a dihedral angle of 5.3 (2)°. The benzene ring is nearly orthogonal to the central ring system. The N atom carrying the ethyl and n-bu...
