  .beta.-Adrenergic blocking agents: substituted phenylalkanolamines. Effect of side-chain length on .beta.-blocking potency in vitro

  摘要：

  The synthesis of a group of potential beta-blockers bearing a new 5-ethoxysalicylamide substituent on nitrogen is described. These compounds were tested for beta-adrenergic blocking potency in vitro and compared with analogous compounds bearing a tert-butyl group on nitrogen. The new N-substituent increased the beta-blocking potency substantially. In a series of five homologous compounds of the type Ar(CH2)nCHOHCH2NHR (R = 5-ethoxysalicylamide; n = 0-4), two maxima of beta-blocking potency were found for n = 0 and 2. Moreover, the carbon isostere of the corresponding (aryloxy)propanolamine still proved to be a very potent beta-blocker. The ether oxygen in the side chain is therefore not an absolute requirement for activity. Structure-activity relationships are discussed.
