Azinomycin B is a natural product that contains densely assembled functionalities with potent antitumor activity.[1] It is isolated from Streptomyces sahachiroi[2] which is reisolated from S. griseofuscus along with its analog azinomycin A.[3] Azinomycin B can bind within the major groove of DNA and forms covalent interstrand crosslinks (ISCs) with the purine bases.[4][5][6][7] The DNA alkylation and crosslinking by azinomycin B suggests its potent antitumor activity.[8]
Biosynthesis
[edit]The biosynthesis of azinomycin B includes a type 1 polyketide synthase and several nonribosomal peptide synthetases.[9]
