  • Endorphins having placental or pancreatic origin
    Patent number: 4316895
    Abstract: A peptide endorphin having a molecular weight in the range of about 4500 to 5000 daltons is described. This peptide endorphin has .beta.-endorphin-like activity, reacting immunologically to rabbit antisera prepared against .beta.-endorphin and displacing Naloxone from opiate receptors in brain tissue. Unlike .beta.-endorphin, however, this peptide endorphin does not exhibit respiratory depressor effect when administered to mice. This peptide endorphin can be obtained from placental and pancreatic tissue, preferably by extracting with dilute mineral acid.
