Studies that did not test the peptide alone2

In this study, Melanotan I (afamelanotide) 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 I (afamelanotide).

    In structural and cAMP assay analysis of cyclic and linear MSH analogues, a lysine residue at the C-terminus of the His-Phe-Arg-Trp core sequence was an important determinant of receptor selectivity.

    In plain wordsIn lab tests, one lysine in the core of MSH analogues helped decide which melanocortin receptor they favour.

    Summary
    Using data from c-AMP assays in combination with structural analysis of melanocortin receptor/ligand models, we conclude that a lysine residue at the C-terminus of the His-Phe-Arg-Trp core sequence of melanocortin hormone is an important determinant for receptor selectivity in the both cyclic and linear MSH analogues.

    In structural analysis of cyclic and linear MSH analogues, side-chain orientation and charge-charge interactions with the ligand appeared critical for receptor selectivity, whereas backbone conformation contributed mainly to receptor binding.

    In plain wordsIn lab tests, side-chain position and charge helped decide receptor choice, while backbone shape mainly affected receptor binding.

    Summary
    Our results suggest that side-chain orientation and charge-charge interactions with the ligand molecule play critical roles in receptor selectivity, whereas the overall backbone conformation or turn type contributes mainly to receptor binding.
