The invention relates to a polypeptide of formula I:-
wherein each of the generic terms is disclosed in full in the specification and includes:-R1 is (2-6C)alkanoyl or (1-4C)alkoxycarbonyl; A1 is a direct link to A2, or is Gly or Arg; A2 is a direct link to A3, or is Gly or Pro; A3 is a direct link to A4, or is Lys or Lys(Z); A4 is His or D-His; A5 is Trp or MeTrp; A6 is Ala or MeAla; A7 is Val or MeVal; A8 is Gly or Sar; A9 is His or MeHis; and Q is a group of the formula -A10.R2 in which A10 is Leu or D-Leu and R2 is hydroxy, amino, (1-3C)alkylamino or (1-3C)alkoxy; or Q is (1-6C)alkoxy or (1-10C)-alkylamino;
provided that when R1 is acetyl and -A4-A5-A6-A7-A8-A9-Q is -His-Trp-Ala-Val-Gly-His-Leu-NH2 then -A1-A2-A3- is not a direct link to His.
The compounds possess antagonist properties against bombesin-like peptides and are of value in the treatment of malignant disease in warm-blooded animals.
