Synthesis of bradykinin analogs modified in position eight: Synthesis of bradykinin analogs modified in position eight. Krit, N. A.; Ravdel, G. A.; Ivanov, V. T. (M. M. Shemyakin Inst. Bioorg. Chem., Moscow, USSR). Bioorg. Khim., 2(11), 1455-63 (Russian) 1976. CODEN: BIKHD7. 63027-48-5 and 21160-82-7 which are cas registry numbers of chemicals are mentioned. DOCUMENT TYPE: Journal CA Section: 34 (Synthesis of Amino Acids, Peptides, and Proteins) Lys-Arg-Pro-Pro-Gly-Phe-Gly-Pro-OCH(CH2Ph)CO-Arg (I), [8-(N-methyl-L-phenylalanine)]bradykinin, [6-glycine-8-(N-methyl-L-phenylalanine)]bradykinin, and [6-glycine-8-(.beta.-cyclohexyl-L-lactic acid)]bradykinin (II) were prepd. by stepwise coupling reactions. Peptide linkages were formed by active ester or dicyclohexylcarbodiimide condensation reactions, and ester linkages in I-II were formed by reaction of lactic acid derivs. with appropriate acid chlorides. .
