Mycestericins A, B, C, D and E were isolated from the culture broth of Mycelia sterilia ATCC 20349 along with thermozymocidin (= myriocin). Their structures were elucidated on the basis of spectroscopic studies and chemical evidence. The acetate of mycestericin C was identical with the acetate of 6, 7-dihydromyriocin. Mycestericins suppressed the proliferation of lymphocytes in the mouse allogeneic mixed lymphocyte reaction, with a potency similar to that of myriocin.
霉菌素 A、B、C、D 和 E 与 Thermozymocidin(= 多球菌素)一起从无菌菌丝体 ATCC 20349 的培养液中分离出来。它们的结构是根据光谱研究和化学证据阐明的。霉菌素C的乙酸盐与6,7-二氢霉菌素的乙酸盐相同。霉菌素抑制小鼠同种异体混合淋巴细胞反应中淋巴细胞的增殖,其效力与霉菌素相似。
