Endusamycin formerly called CP-63,517 (C47H77O14Na), is a novel polycyclic ether antibiotic produced by a new strain of Streptomyces endus subsp. aureus (ATCC 39574). Recovery, fractionation and purification were achieved using standard procedures. Forms include the endusamycin free acid, mp 95 approximately 105 degrees C, lambda max 232 nm (log E 4.16),(More)
CP-60,993, 19-epi-dianemycin, is a novel polycyclic ether antibiotic produced byStreptomyces hygroscopicus ATCC 39305. Fermentation recovery, purification and crystallization were achieved using standard procedures. CP-60,993 was characterized as a monocarboxylic acid. Elemental analysis suggested a molecular formula of C47H78O14 for the free acid and(More)
