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, Melanotan II 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 Melanotan II.

  1. 01LabNot a test of Melanotan II aloneIn vitro (cell-free)Mechanism

    By NMR-based modelling, the essential core appeared as a V shape with two orientations, and some conformers of SHU9119 and MTII shared the orientation of compound 1 and others that of compound 2.

    In plain wordsIn lab models, MTII can take two different shapes in its key region, like related compounds.

    Summary
    Molecular modeling of these compounds based on their NMR data showed that the essential core appeared as a "V" shape with two different orientations, one for compound 1 and some of the conformers of SHU9119 and MTII, and the other for compound 2 and some other conformers of SHU9119 and MTII.

    Summary · context
    Comparison of the structures by NMR and molecular modeling of compounds 1 and 2 vs SHU9119 and MTII indicated that, even though they existed as an average of several conformations in solution, there were distinctions in their structures.

    In this study, Melanotan II 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 Melanotan II.

  2. 02LabNot a test of Melanotan II aloneIn vitro (cell-free)Mechanism

    By NMR-based modelling, the remaining conformers of SHU9119 and MTII that mapped to neither compound 1 nor 2 were suggested to lie outside the hMC-4R binding envelope.

    In plain wordsIn lab models, some shapes of MTII did not fit the MC-4R binding site.

    Summary
    The remaining conformers of SHU9119 and MTII, which did not map to compound 1 or 2, suggested that they were outside of the hMC-4R binding envelop.
