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, Delta sleep-inducing peptide (DSIP) 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 Delta sleep-inducing peptide (DSIP).

  1. 01LabNot a test of Delta sleep-inducing peptide (DSIP) aloneEx vivo tissuePharmacokinetics

    In human or rat blood incubations, DSIP was degraded and released products that eluted on gel filtration like tryptophan.

    In plain wordsIn lab tests with human or rat blood, DSIP broke down and released a product that behaved like tryptophan.

    Summary
    Incubation of DSIP in human or rat blood led to release of products having retention times on a gel filtration column equivalent to Trp.
    1 context sentence
    Summary · context
    The biostability of DSIP (delta sleep-inducing peptide) and two analogs in blood was investigated in order to determine if rates of inactivation contribute to variable effects in vivo.

    In this study, Delta sleep-inducing peptide (DSIP) 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 Delta sleep-inducing peptide (DSIP).

  2. 02LabNot a test of Delta sleep-inducing peptide (DSIP) aloneEx vivo tissuePharmacokinetics

    In blood incubations, formation of DSIP degradation products depended on temperature, time and species.

    In plain wordsIn lab tests with blood, how much DSIP broke down depended on temperature, time and species.
