Phenylbiguanide (PBG) is a 5-HT3 agonist used to study the role of 5-HT3 receptors in the central nervous system. [1] It has been found to trigger dopamine release in the nucleus accumbens of rats. [ 2 ]
Biguanide (/ b aɪ ˈ ɡ w ɒ n aɪ d /) is the organic compound with the formula HN(C(NH)NH 2) 2. It is a colorless solid that dissolves in water to give a highly basic solution. It is a colorless solid that dissolves in water to give a highly basic solution.
The Craig plot, named after Paul N. Craig, is a plot of two substituent parameters (e.g. Hansch-Fujita π constant and sigma constant) used in rational drug design. [1] Two most used forms of a Craig plot are plotting the sigma constants of the Hammett equation versus hydrophobicity; plotting the steric terms of the Taft equation against ...
meta-Chlorophenylbiguanide (1-(3-Chlorophenylbiguanide, m-CPBG) is an allosteric agonist and modulator of the 5-HT 3 receptor [1] [2] [3] and an antagonist of the α 2A-adrenergic receptor. [4] It has anxiogenic , emetic and hypothermic effects in animal studies.
An example published in Organic Syntheses is the conversion of cyclobutanecarboxamide, easily synthesized from cyclobutylcarboxylic acid, to cyclobutylamine. [2] The primary amine is initially present as its trifluoroacetate salt, which can be converted to the hydrochloride salt to facilitate product purification. [1] [2]
Structure of chlorhexidine, a bisbiguanide antiseptic.. Bisbiguanides are a class of chemically related compounds known for their bactericidal properties. Generally considered to be of the generic formula: R 1 R 2 N.C(:NR 6)NH.C(:NH)NH.CH 2 X--(CH 2) 3 NH.C(:NH)NH.C(:NR 7)NR 3 R 4 V. [1] These compounds include the antiseptics chlorhexidine and alexidine.
Buformin hydrochloride is a fine, white to slightly yellow, crystalline, odorless powder, with a weakly acidic bitter taste. Its melting point is 174 to 177 °C, it is a strong base, and is freely soluble in water, methanol and ethanol, but insoluble in chloroform and ether.
Like other hydroxylamines it will react with aldehydes to form nitrones, illustrative is the condensation with benzaldehyde to form diphenylnitrone, a well-known 1,3-dipolar compound: [4] C 6 H 5 NHOH + C 6 H 5 CHO → C 6 H 5 N(O)=CHC 6 H 5 + H 2 O. Phenylhydroxylamine is attacked by NO + sources to give cupferron: [5] C 6 H 5 NHOH + C 4 H 9 ...
