[4-aminobutyrophenones with hypotensive activity]

G Cascio, E Manghisi, R Erba

    Il Farmaco; Edizione Scientifica
    |June 1, 1976
    PubMed
    Summary

    Researchers synthesized novel butyrophenones to decrease neuroleptic activity and increase hypotensive effects. A promising compound, 1-(4'-fluorobenzoyl)-3-pyrrolidinyl-propane, demonstrated significant hypotensive activity with minimal neurological impact.

    Area of Science:

    • Medicinal Chemistry
    • Pharmacology

    Context:

    • Butyrophenones are a class of drugs known for their neuroleptic properties.
    • Existing butyrophenones often exhibit significant central nervous system side effects.
    • There is a need for butyrophenone derivatives with improved safety profiles and enhanced therapeutic effects.

    Purpose:

    • To synthesize novel butyrophenone derivatives.
    • To reduce the neuroleptic activity associated with butyrophenones.
    • To enhance the hypotensive effects of this drug class.

    Summary:

    • A series of new butyrophenones were synthesized and screened for toxicity using the Irwin scheme.
    • Compounds were tested for their effects on systemic arterial pressure in anesthetized cats.
    • 1-(4 '-fluorobenzoyl)-3-pyrrolidinyl-propane exhibited significant hypotensive activity with negligible neurological effects across multiple species.
    • This compound was further evaluated in rabbits, cats, dogs, rats, and mice for both cardiovascular and central nervous system effects.

    Impact:

    • Identified a novel butyrophenone derivative with a favorable therapeutic window.
    • Potential for developing new antihypertensive agents with reduced side effect profiles.
    • Provides a lead compound for further research into safer and more effective cardiovascular drugs.
