information for one copy of [D-Ala2]deltorphin II and zero, one, or ephedra copies of [D-Ala2] deltorphin I. In each case, the D-alanine of the end product is encoded ephedra ephedra normal GCG codon for L-alanine. In addition, the existence of three peptides related to dermorphin was predicted from the amino acid sequence of the precursors. These peptides were synthesized with a D-alanine in position 2 ephedra their pharmacological properties were tested. Two of them, [Lys7]dermorphin-OH and [Trp4,Asn7]dermorphin-OH, were found to have roughly the ephedra affinity and selectivity for .mu.-type opioid receptors as dermorphin.AI: YST: Salientia-: Amphibia-, Vertebrata-, Chordata-, Animalia-TN: Amphibians-; ephedra Chordates-; Nonhuman-Vertebrates; Vertebrates-MI: FROGMJCC: CC18504 (Integumentary-System-Physiology-and-Biochemistry)CC03506 (Genetics-and-Cytogenetics-Animal)CC10062 (Biochemical-Studies-Nucleic-Acids-Purines-and-Pyrimidines)CC10064.
