Abstract:
Decapeptide and undecapeptides substituted on the N-terminal nitrogen atom by acyl groups which include furo-2-yl, isonicotinyl, nicotinyl, 2-, 3-, and 4-quinolinecarbonyl, shikimyl, dihydroshikimyl, and tetrahydrofur-2-oyl are potent antagonists of LHRH and are useful for hormones the levels of sex hormones in mammals.
Abstract:
The present invention provides a class of decapeptide compounds which are potent antagonists of LHRH activity and which have the structure A?1-D2-E3-G4-J5-L6-M7-Q8-R9-T10¿. The compounds of the percent invention are characterized by having an Φ-amino-functionalized side chain on the D-aminoacyl residue at position 6. The Φ-amino group of this side chain is further derivatized by the attachment of an extending group which likewise has a terminal amino group which is capped by an acyl group.
