Nitrogen-containing Sugars. III

Natural products containing a nitrogen-nitrogen bond.

As of early 2013, over 200 natural products are known to contain a nitrogen-nitrogen (N-N) bond. This report categorizes these compounds by structural class and details their isolation and biological activity.

Nucleotides containing variously modified sugars: energetics, structure, and mechanical properties.

The influence of various sugar residue modifications on intrinsic energetic, conformational, and mechanical properties of 2'-deoxyribonucleotide-5'-monophosphates (dNs) was comprehensively investigated using modern quantum chemical approaches. In total, fourteen sugar modifications, including double bonds and heteroatoms (S and N) inside the sugar ring, as well as fluorination in various positi...

Activity of nitrogen-containing and non-nitrogen-containing bisphosphonates on tumor cell lines.

We synthesized and tested three series of bisphosphonates for their activity in inhibiting the growth of three human tumor cell lines: MCF-7 (breast), NCI-H460 (lung), and SF-268 (CNS). The first series of compounds consisted of 49 nitrogen-containing bisphosphonates, the most active species being a tetrakispivaloyloxymethyl (POM) ester, having an (average) IC(50) of 6.8 microM. The second seri...

MATERIALS CHEMISTRY COMMUNICATION Nitrogen-containing carbon nanotubes

could be prepared by employing appropriate precursor molecules. Nanotubes containing both boron and nitrogen have Carbon nanotubes containing small amounts of nitrogen are been grown in the electric arc discharge between graphite produced by the pyrolysis of aza-aromatics such as pyridine, cathodes and graphite anodes filled with boron in a nitrogen methylpyrimidine and triazine over cobalt nan...
