A method for the synthesis of daptomycin or a daptomycin analogue is carried out on a resin to form a linear precursor followed by a serine ligation macrocyclization in solution. Daptomycin analogues can differ from daptomycin by substitution of amino acids residues and/or deletion or addition of amino acid residues. Daptomycin analogues can include a different fatty acid in the side arm of the daptomycin analogue.

lipopeptides assembled by nonribosomal peptide synthetase (NRPS) enzymes. Active site modification of the 3‐methyl glutamate activating adenylation (A) domain of the CDA NRPS enables the incorporation of synthetic 3‐methyl glutamine into CDA. This provides the first example of how A‐domains can be engineered to introduce synthetic “non‐natural” amino acids into nonribosomal peptides.
钙依赖性抗生素(CDA)是由非核糖体肽合成酶(NRPS)组装而成的环状脂肽。CDA NRPS 的 3-甲基谷氨酸激活腺苷酸化 (A) 域的活性位点修饰能够将合成的 3-甲基谷氨酰胺掺入 CDA。这提供了如何设计 A 域以将合成的“非天然”氨基酸引入非核糖体肽的第一个例子。
