Dichloroisoproterenol is also known as Dichloroisoprenaline (DCI), was the first beta blocker ever to be developed. It is non-selective for the β1-adrenergic and β2-adrenergic receptors. DCI has low potency and acts as a partial agonist antagonist at these receptors. Dichloroisoprenaline is a racemic mixture of enantiomers.
Mabuterol is a selective agonist of β2 adrenoreceptor with no beta 1-stimulation. Mabuterol inhibited the positive inotropic effect of isoprenaline at 10(-7) g ml and decreased the maximum driving frequency at 3 X 10(-6) g ml. Mabuterol was 3 times more p
Mabuterol, (S)- is a D isoform of Mabuterol, which is a selective β2 adrenoreceptor agonist. Mabuterol has been found to decrease the blood pressure in rats and increase heart rate and contractile force in guinea pigs. Mabuterol inhibited the positive inotropic effect of isoprenaline but has no effect on alpha-adrenergic, acetylcholine and histamine receptors.
D-Mabuterol hydrochloride is a D isoform of Mabuterol, which is a selective β2 adrenoreceptor agonist. Mabuterol has been found to decrease the blood pressure in rats and increase heart rate and contractile force in guinea pigs. Mabuterol inhibited the positive inotropic effect of isoprenaline but has no effect on alpha-adrenergic, acetylcholine and histamine receptors.
Mabuterol, (R)- is a D isoform of Mabuterol, which is a selective β2 adrenoreceptor agonist. Mabuterol has been found to decrease the blood pressure in rats and increase heart rate and contractile force in guinea pigs. Mabuterol inhibited the positive inotropic effect of isoprenaline but has no effect on alpha-adrenergic, acetylcholine and histamine receptors.
