The chemical total synthesis of gallidermin specifically demands the accurate incorporation of modified amino acids and the formation of thioether bridges characteristic of lantibiotics. The synthesis of lanthionine rings and their subsequent integration into the peptide backbone on a solid phase are critical steps. Researchers have developed methodologies for the synthesis of orthogonally protected lanthionines, which can then be utilized in the solid-supported total synthesis of gallidermin and other related lantibiotics. For instance, the synthesis of specific lanthionine moieties, such as those found in gallidermin, has been reported, paving the way for their incorporation into the total synthesis of the complete molecule.

The efficiency of solid phase synthesis techniques is often evaluated by the overall yield and purity of the synthesized peptide. While SPPS is a method used to create peptides with relative ease, achieving high yields for complex molecules like gallidermin can be challenging.
