N-Vinylpyrrolidone (NVP) is an organic compound consisting of a 5-membered lactam ring linked to a (2 carbon) vinyl group. It is a colorless liquid although commercial samples can appear yellowish. It is produced industrially by vinylation of 2-pyrrolidone, i.e. the base-catalyzed reaction with acetylene. [2]
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties. [2]
Using the same principle it is used to remove polyphenols in beer production and thus clear beers with stable foam are produced. [2] One such commercial product is called Polyclar. PVPP forms bonds similar to peptidic bonds in protein (especially, like proline residues) and that is why it can precipitate tannins the same way as proteins do. [3]
The researchers fed both male and female mice food containing 0.15% aspartame daily — the equivalent of a person drinking three cans (or about 1 litre) of diet soda a day — for 12 weeks.
The researchers reviewed 601 published trials of older people to investigate whether the efficacy of three medications — DPP-4 inhibitors, SGLT2 inhibitors, and GLP-1 agonists — was affected ...
The Food and Drug Administration (FDA) recently approved the nasal spray Spravato for the treatment of major depression in people who have not responded to at least two oral antidepressants.
2-Pyrrolidone, also known as 2-pyrrolidinone or butyrolactam, is an organic compound consisting of a 5-membered lactam, making it the simplest γ-lactam. It is a colorless liquid that is miscible with water and most common organic solvents.
GLP-1 receptor agonists are already being used to treat alcohol use disorder in some circumstances, Dr. Sarhan says, noting that this is a growing trend in addiction disorder medicine ...
