Convenient synthesis of human calcitonin and its methionine sulfoxide derivative.
The human calcitonin peptide chain was assembled using Fmoc solid-phase peptide synthesis chemistry. The combinations of cleavage Reagent H with trans-[Pt(en)(2)Cl(2)](2+) and Reagents B, K, and R with trans-[Pt(CN)(4)Cl(2)](2-) provide convenient methods for the synthesis of human calcitonin and its methionine sulfoxide derivative; the formation of intramolecular disulfide bonds by the above Pt(IV) oxidants is essentially quantitative.
