    Phenformin hydrochloride has active electron pairs on nitrogen atoms, enabling hydrogen bonding and metal coordination. This explains its antidiabetic action through competition with insulin for essential elements.

    Area of Science:

    • Medicinal Chemistry
    • Biochemistry
    • Electrochemistry

    Background:

    • Phenformin hydrochloride is an antidiabetic biguanide.
    • The molecular interactions of biguanides are crucial for their biological activity.

    Purpose of the Study:

    • To investigate the electronic properties of phenformin hydrochloride.
    • To elucidate the mechanisms underlying the antidiabetic action of biguanides.

    Main Methods:

    • Polarographic analysis to detect hydrogen catalytic waves.
    • Chemical analysis to infer the presence of active electron pairs.

    Main Results:

    • A hydrogen catalytic polarographic wave was observed, indicating active electron pairs on phenformin's nitrogen atoms.

  • Biguanides can form hydrogen bridges with biomolecules like amino acids and proteins.
  • Biguanides form coordination complexes with metallic cations, such as zinc.

    • Conclusions:

    • Active electron pairs on phenformin facilitate hydrogen bonding and metal coordination.
    • The antidiabetic effect of phenformin involves competition with insulin for cationic oligoelements.
    • Hydrogen bonding between biguanides and insulin contributes to the antidiabetic mechanism.
