    Summary
    This summary is machine-generated.

    New double-enkephalins, featuring a second active fragment linked by a diamine bridge, show high biological activity. Their potency varies with the diamine bridge size, indicating a key structural determinant for enkephalin analogue efficacy.

    Area of Science:

    • Medicinal Chemistry
    • Pharmacology
    • Peptide Science

    Background:

    • Enkephalin analogues are studied for their biological activities.
    • Previous research informed the design of novel peptide structures.

    Purpose of the Study:

    • To propose and synthesize a new class of enkephalin analogues called double-enkephalins.
    • To evaluate the biological activity of these novel compounds.

    Main Methods:

    • Synthesis of double-enkephalin analogues with varying diamine bridge lengths.
    • Assessment of biological activity using the guinea-pig ileum assay.

    Main Results:

    • The synthesized double-enkephalins exhibited significant biological activity.
    • Activity levels were found to be dependent on the size of the diamine bridge.

    Conclusions:

    • Double-enkephalins represent a promising class of compounds with high biological activity.
    • The diamine bridge length is a critical factor influencing the efficacy of these enkephalin analogues.
