  β1- and β2-Adrenoceptor antagonist activity of a series of para-substituted N-isopropylphenoxypropanolamines

  摘要：

  To further explore the structure-activity relationships of beta-adrenoceptor (beta-AR) antagonists, a series of 25 para-substituted N-isopropylphenoxy-propanolamines were synthesised, nine of which are new compounds. All have been examined for their ability to antagonise beta(1)-ARs in rat atria and beta(2)-ARs in rat trachea. Substitution in the para-position of the phenyl ring is thought to confer B-3-specificity and the selectivity of these compounds for the beta(1)-AR ranges from 1.5-234. None of the compounds tested were selective for the beta(2)-AR. Of the 25 compounds studied, 22 had reasonable (pA(2) > 7) potencies for the rat beta(1)-AR. Only compound I displayed reasonable (pA(2) > 7) potency for the rat beta(2)-AR. Twenty two compounds were used as the training set for comparative molecular field analysis (CoMFA) of antagonist potency (pA(2)) at the rat beta(1)- and beta(2)-ARs. The inclusion of a number of additional physical characteristics improved the QSAR analysis over models derived solely using the CoMFA electrostatic and steric fields. The final models predicted the beta(1)- and beta(2)-AR potency of the compounds in the training set with high accuracy (r(2) = 0.93 and 0.86 respectively). The final beta(1)-AR model predicted the beta(1)-potencies of two out of the three test compounds, not included in the training set, with residual pA(2) values < -0.14, whereas the test compounds were not as well predicted by our final beta(2)-AR model (residual pA(2) values < -0.38).
