Zusammenfassung: | FIELD: organic chemistry, peptides. SUBSTANCE: invention relates to peptides of the general formula (I) where R is C1-7-alkyl; R is C1-4-alkyl; X is C1-5-alkyl; R is a lower alkyl; B - is C1-5-alkyl; D is C1-5-alkoxy; M - phenylalanine; R - H; R - H or benzyl; d = 0 or 1, or their salts showing the improved therapeutic properties for treatment of patients with neoplasms as compared with dolostatine-10. Proposed analog can be synthesized by conventional methods unlike to the latter. EFFECT: improved therapeutic properties. 2 cl, 2 tbl, 2 ex |
