The terminal aminotriguanidine obtained by hydrolysis of phleomycin G is identical with synthetic 1-[[4-((3-[4-{3-(4-aminobutyl)guanidino}butyl]guanidino)butyl]]guanidine (4). The branched isomer 1-(4-aminobutyl)-2,3-bis(4-guanidinobutyl)guanidine (5) has also been prepared for comparison with the hydrolysis base.
