Results from this study2

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone2

In this study, Semax was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Semax.

  1. 01LabNot a test of Semax aloneIn vitro (cell-free)Pharmacokinetics

    In enzyme assays, Pro-Gly-Pro-Leu, Pro-Gly-Pro-Gly and Pro-Gly-Pro were considerably more stable to proteolysis than semax.

    In plain wordsIn lab tests, three simple Pro-Gly-Pro peptides broke down much more slowly than semax in enzyme assays.

    Summary
    It is shown that all three peptides are considerably more stable to proteolysis by N-leucine-aminopeptidase (EC 3.4.11.1, Sigma, type VI, 9.2 units/mg), and by enzymes of nasal slime, brain microsomal fractions, and rat blood.

    Summary · context
    Proteolysis of Pro-Gly-Pro-Leu, Pro-Gly-Pro-Gly and Pro-Gly-Pro were studied comparatively to Met-Glu-His-Phe-Pro-Gly-Pro (semax).

    In this study, Semax was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Semax.

  2. 02LabNot a test of Semax aloneIn vitro (cell-free)Pharmacokinetics

    In enzyme assays, proteolysis of semax gave His-Phe-Pro-Gly-Pro as the only metabolite.

    In plain wordsIn lab tests, enzymes broke semax down into one fragment only, His-Phe-Pro-Gly-Pro.
