It is produced by the strain of Pachybasium sp. It has strong anti-candida albicans B311 activity in the presence of aculeacin with 0.05 ㎍/mL. Cerebroside D is a glycoceramide compound with antitumor activity. Study on murine experimental colitis showed that cerebroside D reduced weight loss and the macroscopic as well as microscopic appearances of colitis induced by dexran sulfate sodium. Cerebroside D also inhibited proliferation and induced apoptosis of T cells activated by concanavalin A or anti-CD3 plus anti-CD28 antibodies.
