Bleomycin is a nonribosomal peptide that is a hybrid peptide-polyketide natural product. The peptide / polyketide / peptide backbone of the bleomycin aglycon is assembled by the bleomycin megasynthetase, which is made of both nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) modules.t is believed to primarily work by preventing the making of DNA. Bleomycin was discovered in 1962. It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.
