    Summary

    New synthetic compounds, structurally similar to tilorone, effectively bind to DNA. One compound, a bis-benzodifuranic acid ester, demonstrated twice the interferon-stimulating activity of tilorone in mice.

    Area of Science:

    • Medicinal Chemistry
    • Molecular Biology
    • Pharmacology

    Background:

    • Tilorone is a known interferon stimulator with a specific molecular structure.
    • Novel compounds with similar structures can be explored for therapeutic potential.

    Purpose of the Study:

    • To synthesize and characterize novel compounds analogous to tilorone.
    • To investigate the DNA-binding capabilities of these new compounds.
    • To evaluate their efficacy in stimulating interferon production in vivo.

    Main Methods:

    • Chemical synthesis of four novel compounds based on furocoumarin, benzodipyrone, and benzodifuran nuclei.
    • DNA complexation studies involving intercalation and electrostatic interactions.
    • In vivo interferon production assays in mice, comparing activities against tilorone.

    Main Results:

    • Four new compounds were successfully synthesized, featuring a tricyclic moiety and basic side chains.
    • All synthesized compounds formed complexes with DNA through intercalation and electrostatic binding.
    • One compound, the diethylamino ethyl ester of bis-benzodifuranic acid (III), showed significantly enhanced interferon production, double that of tilorone.

    Conclusions:

    • The synthesized compounds exhibit DNA-binding properties similar to tilorone.
    • The bis-benzodifuranic acid derivative (III) shows promising potential as a more potent interferon stimulator.
    • Further research into these compounds could lead to new therapeutic agents.
