1. 3-amino-5-hydroxybenzoic acid in antibiotic biosynthesis. XI. Biological origins and semisynthesis of thionaphthomycins, and the structures of naphthomycins I and J
A M Hooper, R W Rickards J Antibiot (Tokyo). 1998 Sep;51(9):845-51. doi: 10.7164/antibiotics.51.845.
Fermentations of Streptomyces sp. E/784 produce low levels of the novel C-30 alkylthio-substituted ansamycin antibiotics naphthomycins J (9) and I (10), in addition to the more abundant C-30 hydroxylated analogues actamycin (1) and naphthomycin D (2) and C-30 chlorinated analogues naphthomycins H (3) and A (4). The addition of N-acetyl-L-cysteine to the fermentation medium substantially increases the production of the thionaphthomycins J and I at the expense of their chloro analogues H and A. Other thiols and thiol progenitors are similarly utilised, including N-acetyl-L-cysteine methyl ester which affords the known naphthomycin F (8) and its novel 2-demethyl homologue (7). The formation of thioansamycins from chloroansamycins and thiols in vivo is probably non-enzymic since similar conversions can be effected in vitro.
