摘要

Three analogs of human β-endorphin (β(h)-EP) have been synthesized: [Gly 31]β(h)-EP, [Gly 31]β(h)-endorphinamide, and [Gly 31]β(h)-endorphinylglycine. All are more active than β(h)-EP in both the guinea pig ileum bioassay and the opiate receptor binding assay. The last two analogs are about twice as active as β(h)-EP in an assay for analgesia. Modification at position 31 and extension at the COOH terminus may afford a route toward analogs with even greater biological activity.
