All individuals in MeSH

Label Id Description
Nitrogen Isotopes D009587 [Stable nitrogen atoms that have the same atomic number as the element nitrogen, but differ in atomic weight. N-15 is a stable nitrogen isotope. ]
Nitrogen Mustard Compounds D009588 [A group of alkylating agents derived from mustard gas, with the sulfur replaced by nitrogen. They were formerly used as toxicants and vesicants, but now function as antineoplastic agents. These compounds are also powerful mutagens, teratogens, immunosuppressants, and carcinogens. ]
Nitrogen Oxides D009589 [Inorganic oxides that contain nitrogen. ]
Nitrogen Radioisotopes D009590 [Unstable isotopes of nitrogen that decay or disintegrate emitting radiation. N atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes. ]
Nitrogen-Fixing Bacteria D000072738 [Bacteria that are capable of NITROGEN FIXATION. ]
Nitrogenase D009591 [An enzyme system that catalyzes the fixing of nitrogen in soil bacteria and blue-green algae (CYANOBACTERIA). EC 1.18.6.1. ]
Nitrogenous Group Transferases D019884 [Enzymes that catalyze the transfer of nitrogenous groups, primarily amino groups, from a donor, generally an amino acid, to an acceptor, usually a 2-oxoacid. EC 2.6. ]
Nitroglycerin D005996 [A volatile vasodilator which relieves ANGINA PECTORIS by stimulating GUANYLATE CYCLASE and lowering cytosolic calcium. It is also sometimes used for TOCOLYSIS and explosives. ]
Nitrohydroxyiodophenylacetate D009592 [Also called 4-hydroxy-3-iodo-5-nitrophenylacetate. A haptenic determinant that can be radiolabeled and used as salts and derivatives for investigations of immunogenic specificity studies. ]
Nitroimidazoles D009593 [IMIDAZOLES having a nitro moiety. ]
Nitromifene D009594 [A non-steroidal estrogen antagonist (as the 1:1 citrate) most commonly used as a research tool in animal studies. ]
Nitroparaffins D009595 [Alkanes having one or more nitro (NO2) groups attached to carbon atoms. ]
Nitrophenols D009596 [PHENOLS carrying nitro group substituents. ]
Nitrophenylgalactosides D009598 [Includes ortho-, meta-, and para-nitrophenylgalactosides. ]
Nitroprusside D009599 [A powerful vasodilator used in emergencies to lower blood pressure or to improve cardiac function. It is also an indicator for free sulfhydryl groups in proteins. ]
Nitroquinolines D009600 [Quinolines substituted in any position by one or more nitro groups. ]
Nitroreductases D009601 [Enzymes which reduce nitro groups (NITRO COMPOUNDS) and other nitrogenous compounds. ]
Nitrosamines D009602 [A class of compounds that contain a -NH2 and a -NO radical. Many members of this group have carcinogenic and mutagenic properties. ]
Nitrosation D015538 [Conversion into nitroso compounds. An example is the reaction of nitrites with amino compounds to form carcinogenic N-nitrosamines. ]
Nitrosative Stress D000073039 [A metabolic excess of REACTIVE NITROGEN SPECIES, including NITRIC OXIDE and PEROXYNITRITE, that leads to damaging effects of oxidation and nitration. ]
