An approach to peripheral vasodilator-beta-adrenergic blocking agents.

J J Baldwin, R Hirschmann, P K Lumma

    Journal of Medicinal Chemistry
    |August 1, 1977
    PubMed
    Summary

    New imidazole derivatives with a tert-butylamino-hydroxypropoxy group were synthesized. These compounds were evaluated for their potential antihypertensive, vasodilating, and beta-adrenergic blocking activities, revealing structure-activity relationships.
