Novel analogs of enkephalin: identification of functional groups required for biological activity
摘要:
Novel tri- and tetrapeptide analogues of enkephalin, in conjunction with earlier structure-activity data, confirm that chemical substitutents present in the first and fourth residues of enkephalin are required for in vitro biological activity. A class of arylamino and alkylamino derivatized tripeptides also were found to have significant in vitro opioid-like activity indistinguishable from [D-Ala2,D-Leu5]enkephalin and morphine.

Novel derivatives of 1-aminoindan and their salts are described. Optically active 1-aminoindan derivatives are prepared by reacting a N-benzyl analog of the desired compound with an enantiomer of mandelic acid. Parkinson's disease, dementia, epilepsy, convulsions, or seizures are treated by administering a compound of the formula:
