Rink amide AM resins or Rink amide MBHA resins are taken as starting chemicals. According to the solid phase synthesis, amino acids with protective groups are sequentially connected to give protective decapeptide resins. Crude product is obtained through sequential removing of Fmoc-protective groups and removal of the side chain protective groups and cutting peptides.
Crude products are separated and purified by C18 column and freeze-dried.
The drug used for the treatment of:
