In the pharmaceutical industry, N-methyl-2-pyrrolidone is used in the formulation for drugs by both oral and transdermal delivery routes. [4] It is also used heavily in lithium ion battery fabrication, as a solvent for electrode preparation, because NMP has a unique ability to dissolve polyvinylidene fluoride binder.
2-Pyrrolidone itself is used in inkjet cartridges. [5] A variety of pharmaceutical drugs are 2-pyrrolidone derivatives, including cotinine, doxapram, povidone, and ethosuximide, and the racetams. The chemical is an intermediate in the production of the polyvinylpyrrolidone precursor vinylpyrrolidone. [3]
γ-Butyrolactone (GBL) or gamma-butyrolactone is an organic compound with the formula O=CO(CH 2) 3. It is a hygroscopic, colorless, water-miscible liquid with a weak characteristic odor. It is the simplest 4-carbon lactone. It is mainly used as an intermediate in the production of other chemicals, such as N-methyl-2-pyrrolidone. [5]
Modafinil is a drug that helps keep people awake and alert (wakefulness-promoting agent or "eugeroic"). [ 1 ] [ 2 ] Most of the listed modafinil analogues are drugs that specifically target dopamine reuptake (reabsorption of a neurotransmitter by a neurotransmitter transporter ) with stronger effects ( selective DRIs with improved potency ...
Selective androgen receptor modulators (SARMs) are a novel class of androgen receptor ligands. They are intended to maintain the desirable muscle building effects of anabolic steroids while reducing undesirable androgenic actions (e.g., increased risk of prostate cancer).
Racetams are 2-pyrrolidone derivatives and may sometimes be referred to simply as pyrrolidones (2-oxopyrrolidines). [1] Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide nucleus, which is the chemical structure of piracetam. Racetams are cyclic derivatives of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). [2]
At elevated temperature and in the presence of a palladium catalyst, hydrogenolysis of dihydrolevoglucosenone via levoglucosanol selectively yields tetrahydrofuran-2,5-dimethanol (THF-dimethanol), [8] which is a biodegradable solvent and a bio-based precursor to 1,6-hexanediol (and 1,6-diaminohexane).
It is found in many drugs such as procyclidine and bepridil. It also forms the basis for the racetam compounds (e.g. piracetam, aniracetam). The amino acids proline and hydroxyproline are, in a structural sense, derivatives of pyrrolidine. Nicotine contains an N-methylpyrrolidine ring linked to a pyridine ring.
