Synthesis and preliminary cardiovascular activity of some phenoxypropanolamines as beta blockers
J Kannan, R Giridhar, R Balaraman
Three compounds of phenoxypropanolamine type with chlorine substituted at para (Compound I: PCP) and ortho (Compound II: OCP) positions and without chlorine (Compound III: NCP) were synthesised and characterised by their physical and chemical methods. All the three compounds significantly (P<0.001) reduced the tachycardia induced by isoprenaline in dogs and rats while compound I and compound II significantly (P<0.001) blocked the isoprenaline induced fall in blood pressure implying a non-selective beta, and beta, blocking effect in both species. Compound III did not block the isoprenaline induced fall in blood pressure in both the animals implying a selective beta, action. The blockade produced by compound I & II (2 x 10-6 M) were similar to the effect produced by propranolol (2 x 10-6 M).
