| | GUANABENZ Usage And Synthesis |
| Description | Guanabenz is an α2-adrenergic agonist that exhibits pronounced hypotensive action, and
that is associated with a reduction of overall peripheral vascular resistance, decline in frequency
of cardiac contractions, and reduced cardiac output. | | Originator | Wytensin,Wyeth,US,1982 | | Uses | It is used both independently and in combination with oral diuretics for treating various
degrees of hypertension. | | Uses | alpha agonists | | Definition | ChEBI: Guanabenz is a dichlorobenzene. | | Manufacturing Process | A mixture of 14.0 g of 2,6-dichlorobenzaldehyde, 10.8 g of aminoguanidine
bicarbonate and 100 ml of pyridine was refluxed for 3 hours. The reaction
mixture was poured into water and the crystalline precipitate filtered off; MP
225°C to 227°C. | | Therapeutic Function | Antihypertensive | | Synthesis | Guanabenz, [(2,6-dichlorobenzyliden) amino] guanidine (22.3.1), is synthesized
in one step by reacting 2,6-dichlorobenzaldehyde with amino guanidine. 
| | Purification Methods | Crystallise the guanidine from MeCN and store it in a CO2–free atmosphere. The monoHCl [23256-5-0] has m 178o(dec) [solubility w% at 25o is 1.1(H2O), 5(EtOH), 0.1(EtOAc), 0.06(CHCl3)]. It is an antihypertensive drug. [Holmes et al. Drugs 26 212 1983.] |
