Guanfacine is a centrally acting α-adrenoceptor agonist, more selective for α2-receptors than clonidine. It is an antihypertensive medication that works by reducing blood pressure through its action on the central nervous system. Guanfacine is a white solid and is available under the brand name Tenex (Dr. Reddy’s).

29110-47-2 Usage

Uses

Used in Pharmaceutical Industry:
Guanfacine is used as an antihypertensive agent for the treatment of high blood pressure. It helps in lowering blood pressure by acting on the central nervous system, specifically targeting α2-adrenergic receptors.
Used in Central Nervous System Applications:
Guanfacine is also used in the management of attention deficit hyperactivity disorder (ADHD) due to its ability to stimulate the central nervous system and improve focus and attention in patients.
Used in Research and Development:
Guanfacine's selective action on α2-receptors makes it a valuable compound for research and development in the field of neuroscience, particularly in the study of adrenergic receptor function and the development of new medications for various conditions related to the central nervous system.

Originator

Estulic,Sandoz,Switz.,1980

Manufacturing Process

2,6-Dichlorophenyl-acetyl-guanidine: A solution of 3.245 g (0.055 mol) of guanidine in isopropanol is added to a solution of 11.7 g (0.05 mol) of 2,6- dichlorophenyl-acetic acid ethyl ester (BP 142°C to 143°C/12 mm of Hg) in 20cc of isopropanol. The reaction mixture is allowed to stand overnight and is subsequently concentrated by evaporation. After recrystallizing the residue from methanol/ether 2,6-dichlorophenyl-acetyl-guanidine is obtained in the form of white grains having a MP of 225°C to 227°C. 2,6-Dichlorophenyl-acetyl-guanidine hydrochloride: A solution of 5.6 g (0.025 mol) of 2,-dichlorophenylacetic acid chloride (BP 137°C to 138°C/12 mm of Hg) in 10 cc of toluene is added dropwise to a mixture of 4.5 g (0.076 mol) of guanidine and 60 cc of toluene. The reaction mixture is allowed to stand at room temperature for 20 minutes, is then heated on a steam bath for 2 hours and is subsequently cooled. The resulting precipitate is filtered off and washed twice with 25 cc amounts of water in order to separate the guanidine hydrochloride. The residue (2,6-dichlorophenyl-acetyl-guanidine) is washed with chloroform for further purification and is then dissolved in 50 cc of isopropanol. The pH-value of the solution is adjusted to 6 with ethanolic hydrochloric acid and the solution is cooled. The resulting white needles are again washed with chloroform. The resulting 2.6-dichlorophenyl-acetylguanidine hydrochloride has a MP of 213°C to 216°C.

Therapeutic Function

Antihypertensive

Synthesis

Guanfacin, N-amidino-2-(2,6-dichlorophenyl)acetamide (22.3.2), is also synthesized in a very easy synthesis of reacting the acid chloride or ester of 2,6- dichlorophenylacetic acid with guanidine.

Check Digit Verification of cas no

The CAS Registry Mumber 29110-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,1 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29110-47:
(7*2)+(6*9)+(5*1)+(4*1)+(3*0)+(2*4)+(1*7)=92
92 % 10 = 2
So 29110-47-2 is a valid CAS Registry Number.

Solid-phase synthesis of N,N′-substituted acylguanidines

Dodd, Dharmpal S.,Zhao, Yufen

, p. 1259 - 1262 (2001)

An efficient method for the solid-phase synthesis of N,N′-substituted acylguanidines is presented. The key-step involves the N-acylation of resin immobilized S-methylisothiourea with a variety of carboxylic acids using PyAOP as the coupling agent. The resulting resin bound N-acyl-derivatives are reacted with a host of amines and the N-acyl,N′-alkyl(aryl)guanidines liberated from the resin upon exposure to TFA.

Substituted phenylacetylguanidines: a new class of antihypertensive agents

Bream,Lauener,Picard,Scholtysik,White

, p. 1477 - 1482 (2007/10/05)

The synthesis of a new series of phenylacetylguanidines is described. Several of them exhibited high antihypertensive activity in the rat. The most potent member of the series is N amidino 2 (2,6 dichlorophenyl) acetamide hydrochloride [2,6 dichlorophenylacetylguanidine hydrochloride, compound 19], which is now in clinical study under the clinical code number BS 100-141.
