Synthetic polymers as drugs.

A C Albertsson, L G Donaruma, O Vogl

    Annals of the New York Academy of Sciences
    |January 1, 1985
    PubMed
    Summary

    Synthetic polymers were modified with biologically active compounds like bithionol, primaquine, and vinylsalicylic acids to create novel antibacterial and antimalarial materials. These advanced polymers show potential for targeted drug delivery and controlled degradation.

    Area of Science:

    • Polymer Chemistry
    • Medicinal Chemistry
    • Materials Science

    Background:

    • Biologically active compounds offer therapeutic potential but require suitable delivery systems.
    • Synthetic polymers can be functionalized to incorporate and release active pharmaceutical ingredients.
    • Developing biodegradable polymers with controlled release properties is crucial for biomedical applications.

    Purpose of the Study:

    • To synthesize and characterize novel polymers incorporating biologically active compounds.
    • To investigate the degradation properties and biological activity of these functionalized polymers.
    • To explore the potential of these materials in drug delivery and antimicrobial applications.

    Main Methods:

    • Incorporation of bithionol as bisphenol monomers into polyesters, polyphosphates, and phosphonates.
    • Synthesis of copolycarbonates and polyurethanes using bithionol derivatives.
    • Reaction of primaquine and amantadine with isocyanates and polyepichlorohydrin.
    • Polymerization and copolymerization of vinylsalicylic acids to create polymeric antibacterials.

    Main Results:

    • Bithionol-based copolycarbonates exhibited controlled degradation (approx. 1% per day) under physiological conditions.
    • Primaquine-containing polymers were synthesized via biuret formation and nucleophilic substitution.
    • Vinylsalicylic acid polymers and copolymers demonstrated selective antibacterial activity, tunable by comonomer choice or derivatization.

    Conclusions:

    • Synthetic polymers can be effectively functionalized with biologically active agents to create advanced materials.
    • Degradable polymers with incorporated drugs show promise for controlled release applications.
    • Tailored polymer structures offer selectivity in biological activity, paving the way for targeted therapeutics.
