摘要

β-Adrenergic receptor antagonists are important therapeutics for the treatment of cardiovascular disorders. In the group of β-blockers, much attention is being paid to the third-generation drugs that possess important ancillary properties besides inhibiting β-adrenoceptors. Vasodilating activity of these drugs is produced through different mechanisms, such as nitric oxide (NO) release, β2 -agonistic action, α1 -blockade, antioxidant action, and Ca(2+) entry blockade. Here, a study on evaluation of the cardiovascular activity of five new compounds is presented. Compound 3a is a methyl and four of the tested compounds (3b-e) are dimethoxy derivatives of 1-(1H-indol-4-yloxy)-3-(2-(2-methoxyphenoxy)ethylamino)propan-2-ol. The obtained results confirmed that the methyl and dimethoxy derivatives of 1-(1H-indol-4-yloxy)-3-(2-(2-methoxyphenoxy)ethylamino)propan-2-ol and their enantiomers possess α1 - and β1 -adrenolytic activities and that the antiarrhythmic and hypotensive effects of the tested compounds are related to their adrenolytic properties. © 2016 WILEY-VCH Verlag GmbH & Co.
