Aromatic C-nitrosation of a bioactive molecule. Nitrosation of minoxidil.
Minoxidil (2,4-diamino-6-(piperidin-1'-yl)pyrimidine N(3)-oxide; CASRN 38304-91-5) is a bioactive molecule with several nitrosatable groups widely used as an antihypertensive and antialopecia agent. Here the nitrosation of minoxidil was investigated. The conclusions drawn are as follows: (i) In the pH = 2.3-5.0 range, the minoxidil molecule undergoes aromatic C-nitrosation by nitrite. The domin...
متن کاملS-nitrosation of proteins
Nitric oxide (NO) is a key factor in inflammation as it regulates microvascular permeability, leukocyte adhesion and wound healing. This mini-review addresses mainly spatial and temporal requirements of NO regulatory mechanisms, with special emphasis on S-nitrosation. Endothelial nitric oxide synthase (eNOS)-derived NO induces S-nitrosation of p120 and β-catenin, particularly in response to pla...
متن کاملNitrosation of dietary precursors.
The diet contains a large number of constituents which can be nitrosated in the gastrointestinal tract (especially in the stomach) to potentially carcinogenic nitroso compounds (NOC). The nitrosation of food mixtures has been investigated with a number of assays, such as chemical analysis or detection of alkylating potential, mutagenicity and carcinogenicity. Relatively good information is avai...
متن کاملNitrosation, Thiols, and Hemoglobin: Energetics and Kinetics
Nitrosothiols are powerful vasodilators. Although the mechanism of their formation near neutral pH is an area of intense research, neither the energetics nor the kinetics of this reaction or of subsequent reactions have been addressed. The following considerations may help to guide experiments. (1) The standard Gibbs energy for the homolysis reaction RSNO → RS(•) + NO(•)(aq) is +110 ± 5 kJ mol(...
متن کاملDietary meat, endogenous nitrosation and colorectal cancer.
Colorectal cancer is the third most common cancer in developed countries such as the U.K., but incidence rates around the world vary approx. 20-fold. Diet is thought to be a key factor determining risk: red and processed meat, but not white meat or fish, are associated with an increased risk of colorectal cancer. The endogenous formation of N-nitroso compounds is a possible explanation because ...
