Streptomyces sp. KY40-1, a strain isolated from the Kentucky Appalachian foothills, is the producer of moromycins A (18) and B (19). Further investigations of this strain led to the isolation and structure elucidation of the five new saquayamycins G-K (1-5), along with known compounds. Two of the new compounds bear the unusual aminosugar rednose, which was found here for the first time in angucyclines. The...
