A new compound of ansamitocin was isolated from the extracts of fermentation medium of mutant strain HGF052 derived from Actinosynnema pretiosum ssp. aurantium ATCC 31565, and identified as N-demethyl-desepoxy-9-methoxy-maytansinol (1) on the basis of extensive spectroscopic methods. Bioassay results showed

Access of four new tumor specific folic acid/ansamitocin conjugates is reported that relies on a synthetic strategy based on the combination of mutasynthesis and semisynthesis. Two bromo-ansamitocin derivatives were prepared by mutasynthesis or by a modified fermentation protocol, respectively, that

Ansamitocins are potent antitumor agents produced by Actinosynnema pretiosum. As deduced from their structures, an N-methylation on the amide bond is required among the various modifications. The protein encoded by asm10 belongs to the SAM-dependent methyltransferase family. Through gene inactivation
