Synthesis and Microbiological Activities of 3-Nitropyrazolo-[1,5-d][1,2,4]triazin-7(6H)-ones and Derivatives

Molecules
A new synthetic strategy for pyrazolo[1,5-d][1,2,4]triazin-7(6H)-ones 4 through intramolecular cyclization of alkyl 2-(4-nitro-1H-pyrazol-3-yl)methylene)hydrazine-1-carboxylates 3 is described, allowing us to selectively modify the N-substituent in 3 ...

The 1-((diorganooxyphosphonyl)-methyl)-2,4- and -2,6-diamido benzenes [PDF]

, 1989
1-((Diorgano oxyphosphonyl) methyl)-2,4- and -2,6-dinitro and diamino benzenes are prepared by nitrating an (organophosphonyl) methyl benzene to produce the dinitro compounds which are then reduced to the diamino compounds.

Emission of reactive oxygen species during degradation of iron gall ink [PDF]

, 2010
Iron gall inks are characterised by high contents of acids and transition metals, promoting degradation of cellulose due to hydrolysis and oxidation, respectively. Their chemical interaction with the environment is not well understood, especially in view

Molecular Periphery Design Allows Control of the New Nitrofurans Antimicrobial Selectivity

Molecules
A series of 13 new 3-substituted 5-(5-nitro-2-furyl)-1,2,4-oxadiazoles was synthesized from different aminonitriles. All compounds were screened in the disc diffusion test at a 100 μg/mL concentration to determine the bacterial growth inhibition zone ...

Maleimido substituted aromatic cyclotriphosphazenes [PDF]

, 1985
4-Aminophenoxy cyclotriphosphazenes are reacted with maleic anhydride to produce maleamic acids which are converted to the maleimides. The maleimides are polymerized. By selection of starting materials (e.g., hexakis amino or trisaminophenoxy-trisphenoxy-
