SCH-79687 is a synthetic small molecule that functions as a selective histamine H₃ receptor antagonist. Originally described pharmacologically in 2003, it exhibits both in vitro and in vivo H₃-blocking activity and has demonstrated wake-promoting properties, potential anti-obesity effects, and nasal decongestion (particularly when administered alongside an H₁ antagonist) .
Examples of imidazole-derived agonists and antagonists:Thioperamide, clobenpropit, SCH-79687, r-alpha-methylhistamine.
Quinolinium is a positively charged ion (cation) formed by protonating quinoline. It is similar to ammonium but derived from quinoline, a nitrogen-containing aromatic compound. Quinolinium salts, where the cation is paired with a counterion (like chloride or iodide), are a class of organic compounds with various applications, particularly in photocatalysis and medicinal chemistry.

Cyclothiazide is 3,4-Dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxide substituted at positions 3, 5 and 6 by a 2-norbornen-5-yl group, chlorine, and a sulfonamide group, respectively. A thiazide diuretic, it has been used in the management of hypertension and oedema. It has a role as a diuretic and an antihypertensive agent.

Phosphoramidic acid, ion(2−), also known as phosphoramidate dianion, is the conjugate base of phosphoramidic acid (H₂PO₂NH₂). It has the molecular formula [H₂NPO₂]²⁻ and consists of a phosphorus atom centrally bonded to an amino group (–NH₂), two oxygen atoms (one double-bonded and one single-bonded with a negative charge), and a lone pair of electrons. This dianion plays a role in biochemical and pharmaceutical research, particularly in the study of phosphoryl transfer reactions and enzyme inhibitors. It is typically encountered as part of salts or coordination compounds, and its structure is stabilized by resonance between the phosphorus–oxygen bonds.
Glucose is a simple sugar (monosaccharide) generated during phosynthesis involving water, carbon and sunlight in plants. It is produced in humans via hepatic gluconeogenesis and breakdown of polymeric glucose forms (glycogenolysis). It circulates in human circulation as blood glucose and acts as an essential energy source for many organisms through aerobic or anaerobic respiration and fermentation.
Two reference monosaccharide derivatives 5a and 5b were prepared to determine the stereochemistry at the C-6 position. The major isomer 5b obtained by addition of (4-fluorophenyl)magnesium bromide to glucose-6-aldehyde 4 was converted to the benzylidene derivative 6. This compound has a small J5,6 and only conforms to the S-stereochemistry. The β-cyclodextrin derivative 2f was hydrolyzed and converted to the methyl glycoside to give the minor R-isomer 5a.
