Crystal packing of two 5-substituted 2-methyl-4-nitro-1H-imidazoles
, 2007 Infinite chains connected by N-H...N hydrogen bonding form the primary packing motif in two closely related 4-nitroimidazole derivatives, viz. 5-bromo-2-methyl-4-nitro-1H-imidazole, C4H4BrN3O2, (I), and 2-methyl-4-nitro-1H-imidazole-5-carbonitrile ...

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges
Angewandte Chemie International Edition, EarlyView.Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Synthesis, characterization, and crystal structure of 2-(2-azidophenyl)-3-oxo-3H-indole 1-oxide
Acta Crystallographica Section E: Crystallographic CommunicationsAn attempt to explore the reactivity of the nitro group in the presence of gold catalysis in comparison to the azide group yielded intriguing results. Surprisingly, only the nitro group exhibited reactivity, ultimately giving rise to the formation of the

Nitro group as a new anchoring group for organic dyes in dye-sensitized solar cells
, 2012 An organic dye JY1 bearing a nitro group was designed, synthesized and applied in DSCs. An unusual colour change was observed when the voltage applied to the device was reversed which was accompanied by a five-fold increase in the cell efficiency.

Conformation preference of 5-nitro group in 1,3-dioxanes [PDF]
, 1975 1. The protonation of the 2-phenyl-5-nitro-1,3-dioxane anion with water leads via equatorial attack to the cis-isomer. 2. 2-Aryl-5-nitro-1,3-dioxanes have a cis-configuration with an axial NO2 group. 3.

New inhibitors of bacterial hyaluronidase - synthesis and structure-activity relationships
, 2006 Potent and selective inhibitors of hyaluronidases are not reported in the literature so far. Such compounds are required as pharmacological tools to investigate the physiological and pathophysiological role of the enzymes and their preferred substrate ...

Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in the environment – A review
, 2017 Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are derivatives of PAHs with at least one nitro-functional group (-NO2) on the aromatic ring. The toxic effects of several nitro-PAHs are more pronounced than those of PAHs.
