ChemInform Abstract: SYNTHESIS AND PHARMACOLOGICAL ACTIVITY OF SOME 2,3-DIHYDRO-1,4-BENZODIOXIN AND 1,3-BENZODIOXOLE DERIVATIVES, AS CYCLIC ANALOGS OF ISOXSUPRINE

A few analogs of the isoxsuprine drug with the phenoxyethyl group incorporated into the heterocyclic 2,3-dihydro-1,4-benzodioxin or 1,3-benzodioxol ring have been synthesized. Among these compounds, the benzodioxol derivative (I e) has been found to possess hypotensive activity in rats in the same range as isoxsuprine, with no alpha-adrenolytic and central sedative properties. Cardiovascular studies in dogs have shown that (I e) is less potent than isoxsuprine, although its activity is longer-lasting at an equally hypotensive dose.
