  • Synthetic peptides having growth promoting activity
    Patent number: 4058512
    Abstract: Novel synthetic peptides of the general formula ##STR1## and the corresponding reduced, linear form. The cyclic form of the peptide is produced by oxidation of the corresponding linear compound thereby providing the divalent dithio group --S--S-- joining the beta carbon of each of the cysteine moieties. In the above formula X is serine (SER) or lysine (Lys), and Y is OH or Thr-Glu-Gly-Phe. The obtained synthetic peptides, in either form, are useful in promoting growth of cells of mammalian tissues.
