2165-19-7 Usage

Originator

Envacar,Pfizer

Uses

Guanoxan is a sympatholytic drug related to Guanethidine (G815000). Guanoxan is used in the treatment of hypertension.

Manufacturing Process

2 Methods of producing of 2-guanidinemethyl-2,3-dihydro-1,4-benzodioxine: 1. 3.3 parts by weight of 2-aminomethyl-1,4-benzodioxane and 2.78 parts by weight of S-methylisothiouronium sulfate were dissolved in 20 parts by volume of water, and the resulting aqueous solution was heated under reflux for 3 h. At the end of this time, the solvent was removed by means of evaporation under reduced pressure and the residue so obtained dissolved in a minimum amount of fresh water and treated with charcoal. Upon filtration, there was obtained a clear filtrate which, on standing, soon afforded pure crystals of di(2-guanidinomethyl-1,4-benzodioxane)sulfate, melting point 204°-205°C. The base 2-guanidinemethyl-2,3-dihydro-1,4-benzodioxine may be obtained by reaction of di(2-guanidinomethyl-1,4-benzodioxane)sulfate with, for example, sodium hydroxide. 2. o-Dihydroxybenzene reacted with epichlorhydrine in the presence sodium hydroxide and 2-hydroxymethyl-2,3-dihydro-1,4-benzodioxine was obtained. To solution of 2-hydroxymethyl-2,3-dihydro-1,4-benzodioxine thionylchloride was added to give 2-chlormethyl-2,3-dihydro-1,4-benzodioxine. 2-Chloromethyl-2,3-dihydro-1,4-benzodioxine reacted with benzylamine to produced 2-benzylaminomethyl-2,3-dihydro-1,4-benzodioxine, which was reduced at the presence of hydrogen and Pd-C (catalyst) to 2-aminomethyl- 2,3-dihydro-1,4-benzodioxine. 2-Aminomethyl-2,3-dihydro-1,4-benzodioxine was treated by Smethylisothiouronium sulfate and there was produced 2-guanidinemethyl-2,3- dihydro-1,4-benzodioxine.

Check Digit Verification of cas no

The CAS Registry Mumber 2165-19-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2165-19:
(6*2)+(5*1)+(4*6)+(3*5)+(2*1)+(1*9)=67
67 % 10 = 7
So 2165-19-7 is a valid CAS Registry Number.

N-Hydroxyl derivatives of guanidine based drugs as enzymatic NO donors

Xian, Ming,Li, Xiaopeng,Tang, Xiaoping,Chen, Xinchao,Zheng, Zhongling,Galligan, James J,Kreulen, David L,Wang, Peng G

, p. 2377 - 2380 (2007/10/03)

Recent research suggests that NO may play a role in the physiological effects of some guanidine-containing drugs. In this report, three guanidine-containing drugs (guanadrel, guanoxan, and guanethidine) together with their N-hydroxyl derivatives were synthesized and their NO-releasing abilities catalyzed by nitric oxide synthases (NOSs) and horseradish peroxidase were evaluated. The guanidine containing compounds could not release NO in the presence of NOS or peroxidase. The corresponding N-hydroxyl compounds exhibited weak NO-releasing ability under the catalyzed of NOS and good NO-releasing ability under the oxidation by horseradish peroxidase in the presence of H2O2. These compounds also displayed vasodilatory activity. Elsevier Science Ltd. All rights reserved.
