S. Sasaki et al., FUNGAL METABOLITES .14. NOVEL POTENT IMMUNOSUPPRESSANTS, MYCESTERICINS, PRODUCED BY MYCELIA-STERILIA, Journal of antibiotics, 47(4), 1994, pp. 420-433
Mycestericins A, B, C, D and E were isolated from the culture broth of
Mycelia sterilia ATCC 20349 along with thermozymocidin (=myriocin). T
heir structures were elucidated on the basis of spectroscopic studies
and chemical evidence. Tile acetate of mycestericin C was identical wi
th the acetate of 6,7-dihydromyriocin. Mycestericins suppressed the pr
oliferation of lymphocytes in the mouse allogeneic mixed lymphocyte re
action, with a potency similar to that of myriocin.
