摘要

Within the relationship of the structure and effect of new beta-adrenolytic agents derivatived from p-hydroxyacetophenone and p-hydroxypropiophenone with a propoxymethyl group in the lipophilic part of the molecule and with a propanamine, a butanamine and a pyrrolidine in the side-chain were studied. In order to prepare these substances, a procedure was selected from several tested ones, in which 4-hydroxy-3propoxymethylphenylketone were treated with chloromethyloxirane and subsequent reaction a hydrobromic acid were prepared 4-(3-brom-2-hydroxypropoxy)-3-propoxymethylalkylketone. Final substances were prepared reaction with amine. The structure of prepared compounds was confirmed on the basic interpretation of the IR, UV and 1H NMR spectra. The results of pharmacological evaluation of selected compounds showed a significant beta 1-blocking activity lower than acebutolol. Their local anesthetic activity is low according with their partition coefficients. The characteristic of the prepared compounds was supplemented by the determination of their partition coefficients, surface tension, dissociation constants and acute toxicity.
