Abstract

Chemical analysis of an Australian marine-derived Streptomyces sp. (CMB-M0150) yielded two new anthracycline antibiotics, aranciamycins I (1) and J (2), as well as the previously reported aranciamycin A (3) and aranciamycin (4). The aranciamycins 1-4, identified by detailed spectroscopic analysis, were noncytotoxic when tested against selected Gram-negative bacteria and fungi (IC₅₀ >30 μM) and exhibited moderate and selective cytotoxicity against Gram-positive bacteria (IC₅₀ >1.1 μM) and a panel of human cancer cell lines (IC₅₀ > 7.5 μM). Significantly, 1-4 were cytotoxic (IC₅₀ 0.7-1.7 μM) against the Mycobacterium tuberculosis surrogate M. bovis bacille Calmette-Guérin.
