AZETOMICINS

摘要

Modified actinomycin compounds that incorporate azetidine in the polypeptide component of the actinomycin molecule are disclosed. These compounds are called azetomicins and specifically incorporate an azetidine derivative in the 3' peptide position in at least one of the two polypeptides normally present in actinomycins. The azetomicins are produced by bio-synthetic means from Streptomyces antibioticus that are cultured on a medium including azetidine-2 carboxylic acid and derivatives thereof.
