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

Studies that did not test the peptide alone3

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. 01AnimalNot a test of Semax aloneAnimal study (in vivo)Activity measurement

    In rats, truncating N-terminal residues of Semax analogs eliminated analgesic activity in the paw-withdrawal test.

    In plain wordsIn rats, shortened versions of Semax at the start of the chain lost their pain-relieving effect.

  2. 02AnimalNot a test of Semax aloneAnimal study (in vivo)Activity measurement

    In rats, Semax analogs with lysine in place of N-terminal methionine, or with glucuronic acid attached to methionine, showed an analgesic effect.

    In plain wordsIn rats, Semax analogs with a swapped or modified first amino acid still reduced pain sensitivity.
