Uses
Oxyfedrine hydrochloride, a vasodilator, is an orally active β-adrenoreceptor agonist. Oxyfedrine decreases the tonicity of coronary vessels. Oxyfedrine hydrochloride can be used in the research of cardiovascular disease[1][2].
Manufacturing Process
45 grams of m-methoxy acetophenone, 8 grams of paraformaldehyde and 30.2 grams of 1 norephedrine were mixed with about 135 cc of isopropanol HCl solution to provide a pH of 4 and the mixture refluxed for 4 hours. The reaction mixture was cooled and the crystals filtered off on a suction filter. 3[1-phenyl-1-hydroxypropyl-(2)-amino]-1-(m-methoxyphenyl)-propanone-(1) HCl was obtained which after recrystallization from methanol had a MP of 190° to 193°C.
Therapeutic Function
Coronary vasodilator
in vivo
Oxyfedrine (14 mg/kg, p.o., for 3-4 weeks) shows anti-anginal action in cats[2].
Oxyfedrine (10 mg/kg, i.p., HCT116 cell xenograft mice) suppresses tumor growth when combined with sulfasalazine (SSZ, 350 mg/kg, i.p.)[1].
Oxyfedrine (1 mg/kg, i.v.) decreases the arterial and venous blood high blood viscosity (HBV) in ice water stress rats[3].
