A new structural class of antibiotics, azicemicins A (1) and B (2) were isolated from the culture broth of Amycolatopsis sp. MJ126-NF4. Their structures were elucidated from their physico-chemical properties, various NMR experiments and chemical transformations and were shown to be 3-(l-methyl-2-aziridinyl)-and 3-(2-aziridinyl)-3,4-dihydro-3,7,8,10,12b-pentahydroxy-9,12-dimethoxy-benz[a]anthracene-l,6(2H,5H)-dione, respectively. © 1995, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
