Lysidine is a derivative of 2-imidazoline. It is a colorless solid with basic properties and soluble in organic solvents. It is used as a precursor to other compounds of pharmaceutical interest.
It is prepared by condensing ethylenediamine with acetic acid to give the diamide, which undergoes CaO-induced cyclization. Alternatively, it arises from the condensation of glyoxal, acetaldehyde, and ammonia.
Lysidine is an intermediate in the synthesis of the drug metronidazole. In the presence of Raney nickel, it undergoes dehydrogenation to 2-methylimidazole, which can then be further elaborated. [3]
Metronidazole, marketed under the brand name Flagyl among others, is an antibiotic and antiprotozoal medication. It is used either alone or with other antibiotics to treat pelvic inflammatory disease, endocarditis, and bacterial vaginosis. It is effective for dracunculiasis, giardiasis, trichomoniasis, and amebiasis. It is an option for a first episode of mild-to-moderate Clostridium difficile colitis if vancomycin or fidaxomicin is unavailable. Metronidazole is available by mouth, as a cream, and by injection into a vein.
5-Nitroimidazole is an organic compound with the formula O2NC3H2N2H. The nitro group at position 5 on the imidazole ring is the most common positional isomer. The term nitroimidazole also refers to a class of antibiotics that share similar chemical structures.
Ornidazole is an antibiotic used to treat protozoan infections. A synthetic nitroimidazole, it is commercially obtained from an acid-catalyzed reaction between 2-methyl-5-nitroimidazole and epichlorohydrin. Antimicrobial spectrum is similar to that of metronidazole and is more well tolerated; however there are concerns of lower relative efficacy.
Mebendazole (MBZ) is a medication used to treat a number of parasitic worm infestations. This includes ascariasis, pinworm infection, hookworm infections, guinea worm infections, hydatid disease, and giardia, among others. It is taken by mouth.
Aminophylline is a compound of the bronchodilator theophylline with ethylenediamine in 2:1 ratio. The ethylenediamine improves solubility, and the aminophylline is usually found as a dihydrate.
Ethylenediamine (abbreviated as en when a ligand) is the organic compound with the formula C2H4(NH2)2. This colorless liquid with an ammonia-like odor is a basic amine. It is a widely used building block in chemical synthesis, with approximately 500,000 tonnes produced in 1998. Ethylenediamine readily reacts with moisture in humid air to produce a corrosive, toxic and irritating mist, to which even short exposures can cause serious damage to health (see safety). Ethylenediamine is the first member of the so-called polyethylene amines.
2-Imidazoline (Preferred IUPAC name: 4,5-dihydro-1H-imidazole) is one of three isomers of the nitrogen-containing heterocycle imidazoline, with the formula C3H6N2. The 2-imidazolines are the most common imidazolines commercially, as the ring exists in some natural products and some pharmaceuticals. They also have been examined in the context of organic synthesis, coordination chemistry, and homogeneous catalysis.
A diamine is an amine with exactly two amino groups. Diamines are used as monomers to prepare polyamides, polyimides, and polyureas. The term diamine refers mostly to primary diamines, as those are the most reactive.
Antiprotozoal agents is a class of pharmaceuticals used in treatment of protozoan infection.
Pinacolone (3,3-dimethyl-2-butanone) is an important ketone in organic chemistry. It is a colorless liquid and has a slight peppermint- or camphor- odor. It is a precursor to triazolylpinacolone in the synthesis of the fungicide triadimefon and in synthesis of the herbicide metribuzin. The molecule is an unsymmetrical ketone. The α-methyl group can participate in condensation reactions. The carbonyl group can undergo the usual reactions. It is a Schedule 3 compound under the Chemical Weapons Convention 1993, due to being related to pinacolyl alcohol, which is used in the production of soman. It is also a controlled export in Australia Group member states.
EDDHA or ethylenediamine-N,N′-bis(2-hydroxyphenylacetic acid) is a chelating agent. Like EDTA, it binds metal ions as a hexadentate ligand, using two amines, two phenolate centers, and two carboxylates as the six binding sites. The complexes are typically anionic. The ligand itself is a white, water soluble powder. Both the free ligand and its tetraanionic chelating agent are abbreviated EDDHA. In contrast to EDDHA, most related aminopolycarboxylic acid chelating agents feature tertiary amines and few have phenolate groups.
Tris(ethylenediamine)cobalt(III) chloride is an inorganic compound with the formula [Co(en)3]Cl3 (where "en" is the abbreviation for ethylenediamine). It is the chloride salt of the coordination complex [Co(en)3]3+. This trication was important in the history of coordination chemistry because of its stability and its stereochemistry. Many different salts have been described. The complex was first described by Alfred Werner who isolated this salt as yellow-gold needle-like crystals.
1,2-Diphenyl-1,2-ethylenediamine, DPEN, is an organic compound with the formula H2NCHPhCHPhNH2, where Ph is phenyl (C6H5). DPEN exists as three stereoisomers: meso and two enantiomers S,S- and R,R-. The chiral diastereomers are used in asymmetric hydrogenation. Both diastereomers are bidentate ligands.
A nucleic acid inhibitor is a type of antibacterial that acts by inhibiting the production of nucleic acids. There are two major classes: DNA inhibitors and RNA inhibitors. The antifungal flucytosine acts in a similar manner.
cis-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl2(en)2]Cl (en = ethylenediamine). The salt consists of a cationic coordination complex and a chloride anion. It is a violet diamagnetic solid that is soluble in water. One chloride ion in this salt readily undergoes ion exchange, but the two other chlorides are less reactive, being bound to the metal center.
Tiamenidine (BAN, USAN, INN, also known as thiamenidine, Hoe 440) is an imidazoline compound that shares many of the pharmacological properties of clonidine. It is a centrally-acting α2 adrenergic receptor agonist (IC50 = 9.1 nM). It also acts as an α1-adrenergic receptor agonist to a far lesser extent (IC50 = 4.85 μM). In hypertensive volunteers, like clonidine, it significantly increased sinus node recovery time and lowered cardiac output. It was marketed (as tiamenidine hydrochloride) by Sanofi-Aventis under the brand name Sundralen for the management of essential hypertension.
N-(1-Naphthyl)ethylenediamine is an organic compound. It is commercially available as part of Griess reagents, which find application in quantitative inorganic analysis of nitrates, nitrite and sulfonamide in blood, using the Griess test.
Ceftolozane/tazobactam, sold under the brand name Zerbaxa, is a combination antibiotic medication used for the treatment of complicated urinary tract infections and complicated intra-abdominal infections in adults. Ceftolozane is a cephalosporin antibiotic, developed for the treatment of infections with gram-negative bacteria that are resistant to conventional antibiotics. It was studied for urinary tract infections, intra-abdominal infections and ventilator-associated bacterial pneumonia.
Acetomepregenol (ACM), also known as mepregenol diacetate and sold under the brand name Diamol, is a progestin medication which is used in Russia for the treatment of gynecological conditions and as a method of birth control in combination with an estrogen. It has also been studied in the treatment of threatened abortion. It has been used in veterinary medicine as well. It has been marketed since at least 1981.
3,9-Diethylidene-2,4,8,10-tetraoxaspiro[5.5]undecane (DETOSU) is a bicyclic ketene acetal derived from the isomeric allyl acetal 3,9-divinyl-2,4,8,10-tetraoxaspiro[5.5]undecane (DVTOSU). As a bifunctional monomer, DETOSU is an important building block for polyorthoesters formed by the addition of diols to the activated double bond of the diketene acetal.
