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-(1-methyl-2-aziridinyl)- and 3-(2-aziridinyl)-3,4-dihydro-3,7,8,10,12b-pentahydroxy-9,12-dimeth oxy-benz [a]anthracene-1,6(2H,5H)-dione, respectively.
从拟无枝酸菌属MJ126-NF4的培养液中分离出了一类新型结构的抗生素——氮杂霉素A（1）和B（2）。通过其物理化学性质、各种核磁共振实验以及化学转化确定了它们的结构，结果表明它们分别是3-（1-甲基-2-氮丙啶基）-和3-（2-氮丙啶基）-3,4-二氢-3,7,8,10,12b-五羟基-9,12-二甲氧基-苯并[a]蒽-1,6(2H,5H)-二酮。
