Direct Nitration of Vinylcycles with Copper Nitrate
Organic Letters, 2023A direct nitration of vinylcyclopropanes is disclosed with Cu(NO3)2 and KI in a regio- and stereoselective manner to afford nitroalkenes efficiently, where the cyclopropane skeleton was retained. The given method could be extended to other vinylcycles as well as biomolecule derivatives with wide substrate scope, good functionality tolerance, and ...

Nitrate signalling: Functions of a nitrate transceptor
Nature Plants, 2015The nitrate transporter NRT1.1 is a versatile plasma-membrane protein that mediates not only nitrate uptake in roots, but also nitrate sensing and signalling. A study of the structural features of NRT1.1 reveals how this protein can coordinate a range of physiological and morphological responses to nitrate.

Nitrates have been used for the last 130 years to treat and control the symptoms of angina pectoris. Within the last 15 years, nitrates also have been shown to limit infarct size and to be beneficial in the treatment of patients with severe intractable heart failure, cardiogenic shock, severe mitral and aortic regurgitation, hypertensive episodes, and ...

Abstract The nitration of bovine pancreatic ribonuclease with tetranitromethane has been studied. A procedure involving solvent extraction of excess reagent and product is described. A spectrophotometric procedure for determining the extent of nitration of tyrosines has been devised, which is not vitiated by the presence of other chromophoric ...

Nitrate transport: a key step in nitrate assimilation
Current Opinion in Plant Biology, 1998The nitrate assimilation pathway has been the matter of intensive research during the past decade. Many genes involved in low and high affinity nitrate uptake have been identified in fungi, algae and, more recently, in plants. The plant genes so far isolated are transcriptionally regulated; their inducibility by nitrate seems to be a common feature ...

The nitrate group of drugs is one of the most commonly used therapeutic modalities. The application of the nitrates is generally directed at ameliorating the symptoms of occlusive coronary artery disease (angina) and/or congestive heart failure. Although studies are available that attempt to refute the concept of nitrate-induced tolerance in angina ...

The surface tension of molten TlNO/sub 3/ has been measured over the temperature range 220-350 /sup 0/C, using the maximum bubble pressure method. We have also measured the surface tension of the binary mixtures TlNO/sub 3/-LiNO/sub 3/ and TlNO/sub 3/-KNO/sub 3/ at 350 /sup 0/C over the entire composition range. 3 tables, 2 figures.

AbstractVerschiedene Mono‐ und Dinitrate von Bicyclo[3.3.0]octanolen2und3, Bicyclo[3.3.1]nonanolen4und 9‐Oxabicyclo[3.3.1]nonanolen5wurden dargestellt und auf antianginöse Aktivität untersucht. Keine der geprüften Substanzen zeigte eine dem Isosorbiddinitrat vergleichbare Wirkung.
