Novel peptides represented by the general formula:
and physiologically acceptable acid addition salts thereof;
where
(A) represents H-, H-Gly, H-Lys-Gly, H-Ser-Lys-Gly, H-Leu-Ser-Lys-Gly, H-Gly-Leu-Ser-Lys-Gly, H-ser, H-Ser-Ser, H-Arg-Ser-Ser, H-Arg-Arg-Ser-Ser, H-Leu-Arg-Arg-Ser-Ser, H-Ser-Leu-Arg-Arg-Ser-Ser;
(B) represents H-Cys or Pmp;
(C) represents Phe-, pCℓ-Phe, pF-Phe, pNO₂-Phe or Cha;
(D) represents Ile, Val, Aib, tLeu, Gly or Leu;
(E) represents Lys or Arg;
(F) represents Ile, Leu or Met;
(G) represents Ser or Ala;
(H) represents Met or Gln;
(I) represents -OH, -Asn-OH, -Asn-Ser-OH, -Asn-Ser-Phe-OH, -Asn-Ser-Phe-Arg-OH or -Asn-Ser-Phe-Arg-Tyr-OH; and the symbol "......." represents a disulfide bond;
provided that 1) α-hANP, 2) α-hANP (7 - 28) and 3) CNP-22 are excluded from the scope of that general formula.
Also disclosed are agents for suppressing the growth of vascular smooth muscle cells that contains those peptides as effective ingredients.
